For maximum accuracy, ACAL should be performed every 24 hours. For example, addi-tional Vdc volts gain errors due to temperature changes are reduced from 1ppm/°C to 0.15ppm/°C (over 6:1) using ACAL. In ACV volts, additional gain error due to temperature changes are reduced from 30ppm/°C to less than 1ppm/°C (over 30:1) using ACAL. The time to perform a complete ACAL is about 12minutes. ACAL ACV takes about 1minute, ACAL DCV takes about 2minutes, and ACAL OHM takes about 9minutes. For monitor-ing temperature changes, the Agilent 3458A provides the TEMP? command (found in the command Menu) to measure the internal instrument tempera-ture.

The device regulates an output voltage as low as 0.8V from a 4.5V to 30V input power supply. The device can provide up to 1.2Amp continuous current to the output. The EUP3458 uses current-mode architecture to control the regulator loop. The output voltage is measured at FB through a resistive voltage divider and amplified through the internal error amplifier.Slope compensation is internally added to eliminate subharmonic oscillation at high duty cycle. The slope compensation adds voltage ramp to the inductor current signal which reduces maximum inductor peak current at high duty cycles.The device uses an internal n-channel switch to step down the input voltage to the regulated output voltage. Since the n-channel switch requires gate voltage greater than the input voltage, a boostrap BS capacitor is connected between SW and BS to drive the n-channel gate.Application InformationSetting the Output VoltageThe output voltage is set through a resistive voltage divider (see Figure1 or 2). The voltage divider divides the output voltage down by the ratio:Thus the output voltage is :The feedback resistor R1 also sets the feedback loop bandwidth with the internal compensation capacitor. R2 can be determined by:InductorThe inductor is required to supply constant current to the output load while being driven by the switched input voltage. A larger value inductor results in less ripple current and lower output ripple voltage. However, the larger value inductor has a larger physical size, higher series resistance, and lower saturation current. Choose an inductor that does not saturate under the worst-case load conditions. A good rule for determining the inductance is to allow the peak-to- peak ripple current in the inductor to be approximately 30% of the maximum load current. Also, make sure that the peak inductor current (the load current plus half the peak-to-peak inductor ripple current) is below the 2A minimum peak current limit.The inductance value can be calculated by the equation: Where V OUT is the output voltage, V IN is the input voltage, f is the switching frequency, and ∆I is the peak-to-peak inductor ripple current.Input CapacitorThe input current to the step-down converter is discontinuous, and therefore an input capacitor C1 is required to supply the AC current to the step-down converter while maintaining the DC input voltage. A low ESR capacitor is required to keep the noise minimum at the IC. Ceramic capacitors are preferred, but tantalum or low-ESR electrolytic capacitors may also suffice. The input capacitor value should be greater than 10µF, and the RMS current rating should be greater than approximately 1/2 of the DC load current. In Figure 1 or 2, all ceramic capacitors should be placed close to the EUP3458. Output CapacitorThe output capacitor is required to maintain the DC output voltage. Low ESR capacitors are preferred to keep the output voltage ripple low. The characteristics of the output capacitor also affect the stability of the regulator control loop. In the case of ceramic capacitors, the impedance at the switching frequency is dominated by the capacitance. For most application, a 22µF ceramic capacitor will be sufficient. Output Rectifier DiodeThe output rectifier diode supplies the current to the inductor when the switch is off. A schottky diode is recommended to reduce losses due to the diode forward voltage and recovery times. The reverse voltage rating of the diode should be greater than the maximum input voltage, and current rating should be greater than the maximum load current.External Boostrap DiodeAn external boostrap diode may improve the efficiency when input voltage is lower than 5.5V or duty cycle is higher than 65%. The external 5V can be a 5V fixed input from system or a 5V output of the EUP3458.()2R /2R 1R V 8.0V OUT +∗=()()()I f V /V V V L IN OUT IN OUT ∆∗∗−∗=()V 8.02R 1R /2R V V OUT FB =+∗=()18.0/V 1R 2R OUT −=Thermal ConsiderationsTo avoid the EUP3458 from exceeding the maximum junction temperature, the user will need to do a thermal analysis. The goal of the thermal analysis is to determine whether the operating conditions exceed the maximum power dissipation which can be calculated by following formula:Where T J(MAX) is the maximum operation junction temperature, T A is the ambient temperature and the θJA is the junction to ambient thermal resistance.Table 1.

For maximum accuracy, ACAL should be performed every 24 hours. For example, addi-tional Vdc volts gain errors due to temperature changes are reduced from 1ppm/°C to 0.15ppm/°C (over 6:1) using ACAL. In ACV volts, additional gain error due to temperature changes are reduced from 30ppm/°C to less than 1ppm/°C (over 30:1) using ACAL. The time to perform a complete ACAL is about 12minutes. ACAL ACV takes about 1minute, ACAL DCV takes about 2minutes, and ACAL OHM takes about 9minutes. For monitor-ing temperature changes, the Agilent 3458A provides the TEMP? command (found in the command Menu) to measure the internal instrument tempera-ture.

Faster system start-upThe value of a fast system multimeter in production test is clear. But it is also important that the dmm programs easily to reduce the learning timefor new system applications. The Keysight Multimeter Language (ML) offers a standard set of commands for the multimeter user that consists of easily understood, readable com-mands. Easier programming and clearer documentation reduce system development time.Faster measurements and setupsNow you can have a system dmm with both fast and accurate measure-ments. The 3458A optimizes your measurements for the right combi-nation of accuracy, resolution, and speed. The 3458A Multimeter fits your needs from 4.5 digit DC volts measurements at 100,000/second,to 8.5 digit DC volts measurements at 6/second, or anywhere in between in 100 ns steps.Even the traditionally slower measure-ment functions, such as AC volts, are quicker with the 3458A. For example,you can measure true rms ACV at upto 50 readings/second with fullaccuracy for input frequencies greaterthan 10 kHz.Besides high reading rates, the3458A’s design was tuned for themany function and level changesrequired in testing your device. The3458A can change function andrange, take a measurement, andoutput the result at 340/second.This is at least 5 times faster thanother dmms. In addition, the 3458Atransfers high speed measurementdata over GPIB or into and out of its75,000 reading memory at 100,000readings/second.You can reduce your data transferoverhead by using the unique non-volatile program memory of the 3458Ato store complete measurementsequences. These test sequences canbe programmed and initiated from thefront panel for stand-alone operationwithout a controller.Finally, the 3458A Multimeter makesfast and accurate measurements.Consider the 3458A’s 0.6 ppm 24 hourDC volts accuracy, 100 ppm AC voltsaccuracy and its standard functions ofDCV, ACV, DCI, ACI, ohms, frequencyand period. Greater measurementaccuracy from your dmm means higherconfidence and higher test yields.More functions mean greater versatilityand lower-cost test systems.Longer system up-timeThe 3458A Multimeter performs acomplete self-calibration of all func-tions, including AC, using high stabil-ity internal standards. This self- orauto-calibration eliminates measure-ment errors due to time drift andtemperature changes in your rack oron your bench for superior accuracy.When it’s time for periodic calibrationto external standards, simply con-nect a precision 10 VDC source anda precision 10 kΩ resistor. All rangesand functions, including AC, are auto-matically calibrated using precisioninternal ratio transfer measurementsrelative to the external standards.The 3458A’s reliability is a product ofKeysight’s “10X” program of defectreduction. Through extensive envi-ronmental, abuse, and stress testingduring the design stages of productdevelopment, has reduced the num-ber of defects and early failures in itsinstruments by a factor of ten overthe past ten years. Our confidencein the 3458A’s reliability is reflectedin the low cost of the option foradditional years of return-to-repair.For High Test System Throughput – Faster system start-upMultimeter Language (ML) compat-ible– Faster measurementsand setups100,000 readings/sec in 4.5 digits50,000 readings/sec in 5.5 digits340 function or range changes/sec– Longer system up-timeMultimeter Language (ML)compatible6In the calibration lab, you’ll find the 3458A’s 8.5 digits to have extraordi-nary linearity, low internal noise, and excellent short term stability. The linearity of the 3458A’s Multislope A to D converter has been characterized with state-of-the-art precision. Using Josephsen Junction Array intrinsic standards, linearity has been mea-sured within ± 0.05 ppm of 10 volts. The 3458A’s transfer accuracy for10 volts DC is 0.1 ppm over 1 hour± 0.5° C. Internal noise has been reduced to less than 0.01 ppm rms yielding 8.5 digits of usable resolution. So, the right choice for your calibration standard dmm is the 3458A.DCV stabilityThe long term accuracy of the 3458A is a remarkable 8 ppm per year—more accurate than many system dmms are after only a day. Option 002 gives you a higher stability voltage reference specified to 4 ppm/year for the ultimate performance. Reduced-error resistanceThe 3458A doesn’t stop with accurate DCV. Similar measurement accuracy is achieved for resistance, ACV, and current. You can measure resistance from 10 µΩ to 1 GΩ with midrange accuracy of 2.2 ppm.Finally, the 3458A, like its dmm pre-decessors, offers offset-compensatedohms on the 10 Ω to 100 kΩ rangesto eliminate the errors introduced bysmall series voltage offsets. Usablefor both two- and four-wire ohms, the3458A supplies a current through theunknown resistance, measures thevoltage drop, sets the current to zero,and measures the voltage drop again.The result is reduced error forresistance measurements.Precision ACVThe 3458A introduces new heights oftrue rms AC volts performance with achoice of traditional analog or a newsampling technique for higher accu-racy. For calibration sources and peri-odic waveforms from 1 Hz to 10 MHz,the 3458A’s precision sampling tech-nique offers extraordinary accuracy.With 100 ppm absolute accuracy for45 Hz to 1 kHz or 170 ppm absoluteaccuracy to 20 kHz, the 3458A willenhance your measurement capabili-ties. Accuracy is maintained for up to2 years with only a single 10 volt DCprecision standard. No AC standardsare necessary. For higher speed andless accuracy, the analog true rmsAC technique has a midband absolutemeasurement accuracy of 300 ppmusing the same simple calibrationprocedure. With a bandwidth of 10 Hzto 2 MHz and reading rates to 50/second, is an excellent choice for highthroughput computer-aided testing.Easy calibrationThe 3458A gives you low cost ofownership with a simple, two-sourceelectronic calibration. With its superiorlinearity, the 3458A is fully calibrated,including AC, from a precision 10 VDCsource and a precision 10 kΩ resistor.All ranges and functions are automat-ically calibrated using precise internalratio transfer measurements relativeto these external standards. In addi-tion, the 3458A’s internal voltagestandard and resistance standard arecalibrated. Now you can perform aself-verifying, self- or auto-calibrationrelative to the 3458A’s low drift inter-nal standards at any time with theACAL command. So, if your dmm’senvironment changes, auto-calibrationoptimizes your measurement accuracy.Calibration securityUnlike other dmms, the 3458A goesto great lengths to assure calibrationsecurity. First, a password securitycode “locks” calibration values andthe self-calibration function. Next, youcan easily store and recall a securedmessage for noting items, such ascalibration date and due date. Plus,the 3458A automatically incrementsa calibration counter each time you“unlock” the dmm — another safe-guard against calibration tampering.If you have a unique situation ordesire ultimate security, use the inter-nal dmm hardwired switch to forceremoval of the instrument covers toperform calibration.For Calibration Lab Precision– 8.5 digits resolution– 0.1 ppm DCV linearity– 100 ppm ACV absoluteaccuracy– 4 ppm/year optionalstability78For High Resolution Digitizing– 16 bits at100,000 samples/sec – Effective rates to 100 Msamples/sec – Signal bandwidth of 12 MHz– 10 ns timing with < 100 psjitterEasily acquire waveformsSimple, application-oriented commands in the Keysight Multimeter Language (ML) make the task of waveform digitizing as easy as measuring DCV. Simply specify the sweep rate and number of samples.Integration or track-and-hold pathsThe 3458A gives you the choice of two configurations for high speed measurements: a 150 kHz bandwidth integrating path with a variable aper-ture from 500 ns to 1 second or a 12 MHz bandwidth path with a fixed 2 ns aperture and 16-bit track-and-hold. Use the integration path for lower noise, but use the track-and-hold path to precisely capture the voltage at a single point on a waveform.Direct sampling functionThe 3458A has two samplingfunctions for digitizing wave-forms: direct sampling and sequential or sub-sampling. With direct sampling, the 3458A samples through the 12 MHz path followed by the 2 ns track-and-hold providing 16 bits of resolution. The maximum sample rate is 50,000 samples/second or 20 µs between samples. Samples can be internally paced by a 0.01% accurate timebase with time increments in 100 ns steps. Data transfers directly to your computer at full speed or into the dmm’s internal reading memory. Waveform reconstruction consists of simply plotting the digitized voltage readings versus the sampling interval of the timebase.Sequential sampling functionSequential or sub-sampling uses the same measurement path asdirect sampling; however sequential sampling requires a periodic input signal. The 3458A will synchronize to a trigger point on the waveform set by a level threshold or external trigger. Once synchronized, the dmm automatically acquires the waveform through digitizing successive periods with time increment steps as small as 10 ns, effectively digitizing at rates up to 100 Msamples/second. All you specify is the effective timebase and the number of samples desired, the 3458A automatically optimizes its sampling to acquire the waveform in the least amount of time. Then, for your ease of use, the 3458A automati-cally re-orders the data in internal memory to reconstruct the waveform.93458A Technical SpecificationsEXAMPLE 5:Absolute Accuracy; 90 DayAssuming the same conditions as Example 4, but now add the traceability error to establish absolute accuracy.(4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV T emperature Coefficient (specification is per °C):(0.15 ppm x 10 V + 0.01 ppm x 10 V) x 10 °C = 16 µV factory traceability error of 2 ppm:(2 ppm x 10 V) = 20 µV T otal absolute error = 78 µVAdditional errorsWhen the 3458A is operated at power line cyclesbelow 100, additional errors due to noise and gainbecome significant. Example 6 illustrates the errorcorrection at 0.1 PLC.EXAMPLE 6:Operating temperature is 28°C; 0.1 PLCAssuming the same conditions as Example 2, but now add additional error.(4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µVReferring to the Additional Errors chart and RMSNoise Multiplier table, additional error at 0.1 PLC is:(2 ppm x 10 V) + (0.4 ppm x 1 x 3 x 10 V) = 32 µV T otal relative error = 74 µV Section 1: DC Voltage 10 Section 7: Digitizing 21Section 2: Resistance 11 Section 8: System Specifications 23Section 3: DC Current 13 Section 9: Ratio 24Section 4: AC Voltage 14 Section 10: Math Functions 24Section 5: AC Current 19Section 11: General Specifications 25Section 6:Frequency/Period 20Section 12: Ordering Information 26IntroductionThe Keysight 3458A accuracy is specified as a part per million (ppm) of the reading plus a ppm of range for DCV, Ohms, and DCl. In ACV and ACl, the speci-fication is percent of reading plus percent of range. Range means the name of the scale, e.g. 1 V, 10 V, etc.; range does not mean the full scale reading, e.g. 1.2 V, 12 V, etc. These accuracies are valid for a specific time from the last calibration.Absolute versus Relative AccuracyAII 3458A accuracy specifications are relative to the calibration standards. Absolute accuracy of the 3458A is determined by adding these relative accuracies to the traceability of your calibration standard. For DCV, 2 ppm is the traceability error from the factory. That means that the absolute error relative to the U.S. National Institute of Standards and T echnology (NIST) is 2 ppm in addition to the DCV accuracy specifications. When you recalibrate the 3458A, your actual traceability error will depend upon the errors from your calibration standards. These errors will likely be different from the error of 2 ppm.EXAMPLE 1:Relative Accuracy; 24 hour operating temperature is Tcal ±1 °CAssume that the ambient temperature for the measurement is within ± 1 °C of the temperature of calibration (T cal). The 24 hour accuracy specification for a 10 V DC measurement on the 10 V range is 0.5 ppm + 0.05 ppm. That accuracy specificationmeans:0.5 ppm of Reading + 0.05 ppm of Range For relative accuracy, the error associated with themeasurement is:(0.5/1,000,000 x 10 V) + (0.05/1,000,000 x 10 V) =± 5.5 µV or 0.55 ppm of 10 VErrors from temperature changesThe optimum technical specifications of the 3458A are based on auto-calibration (ACAL) of the instru-ment within the previous 24 hours and following ambient temperature changes of less than ±1 °C. The 3458A ’s ACAL capability corrects for measure-ment errors resulting from the drift of critical components from time and temperature.The following examples illustrate the error correc-tion of auto-calibration by computing the relative measurement error of the 3458A for various temperature conditions. Constant conditions for each example are:10 V DC input 10 V DC range T cal = 23 °C90 day accuracy specificationsEXAMPLE 2:Operating temperature is 28 °C; with ACALThis example shows basic accuracy of the 3458A using auto-calibration with an operating tempera-ture of 28 °C. Results are rounded to 2 digits.(4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV T otal relative error = 42 µV EXAMPLE 3:Operating temperature is 38 °C; without ACAL The operating temperature of the 3458A is 38 °C, 14 °C beyond the range of T cal ±1 °C. Additional measurement errors result because of the added temperature coefficient without using ACAL.(4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV T emperature Coefficient (specification is per °C):(0.5 ppm x 10 V + 0.01 ppm x 10 V) x 14 °C = 71 µV T otal error = 113 µV EXAMPLE 4:Operating temperature is 38°C; with ACALAssuming the same conditions as Example 3, but using ACAL significantly reduces the error due to temperature difference from calibration tempera-ture. Operating temperature is 10 °C beyond the standard range of T cal ±5 °C.(4.1 ppm x 10 V) + (0.05 ppm x 10 V) = 42 µV T emperature Coefficient (specification is per °C):(0.15 ppm x 10 V + 0.01 ppm x 10 V) x 10 °C = 16 µVT otal error = 58 µVSection 1: DC Voltage10Section 2: Resistance11Measurement ConsiderationKeysight recommends the use of PTFE* cable or otherhigh impedance, low dielectric absorption cable for thesemeasurements.12Section 3: DC CurrentMeasurement ConsiderationsKeysight recommends the use of PTFE cable or other highimpedance, low dielectric absorption cable for low currentmeasurements. Current measurements at rates < NPLC 1are subject to potential noise pickup. Care must be takento provide adequate shielding and guarding to maintainmeasurement accuracies.1314Section 4: AC Voltage Synchronous Sub-sampled Mode (ACV Function, SETACV SYNC)General InformationThe Keysight 3458A supports three techniques for measuring true rms AC voltage, each offering unique capabilities. The desired measurement technique is selected through the SETACV command. The ACV functions will then apply the chosen method for subsequent measurements.The following section provides a brief description of the three operation modes along with a summary table helpful in choosing the technique best suited to your specific measurement need.SETACV SYNC Synchronously Sub-sampled Computed true rms technique.This technique provides excellent linearity and the most accurate measurement results. It does require that theinput signal be repetitive (not random noise for example). The bandwidth in this mode is from 1 Hz to 10 MHz.SETACV ANA Analog Computing true rms conversion technique.This is the measurement technique at power-up or following an instrument reset. This mode works well withany signal within its 10 Hz to 2 MHz bandwidth and provides the fastest measurement speeds.SETACV RNDM Random Sampled Computed true rms technique.This technique again provides excellent linearity, however the overall accuracy is the lowest of the three modes.It does not require a repetitive input signal and is threfore well suited to wideband noise measurements. Thebandwidth in this mode is from 20 Hz to 10 MHz.15Analog Mode(ACV Function, SETACV ANA) 16Random Sampled Mode(ACV Function, SETACV RNDM)171819Section 5: AC Current20Section 5: AC Current continued Section 6: Frequency/Period21Section 7: DigitizingStandard DC Volts Digitizing (DCV Function)General InformationThe Keysight 3458A supports three independent methods for signal digitizing. Each mehtod is discussed below to aid in selecting the appropriate setup best suited to your specific application.DCV Standard DCV function.This mode of digitizing allows signal acquisition at rates from 0.2 readings/sec at 28 bits resolution to 100 k read-ings/sec at 16 bits. Arbitrary sample apertures from 500 ns to 1 sec are selectable with 100 ns resolution. Inputvoltage ranges cover 100 mV to 1000 V full scale. Input bandwidth varies from 30 kHz to 150 kHz depending on themeasurement range.DSDCDirect Sampling DC Coupled measurement technique.DSAC Direct Sampling AC Coupled measurement technique.In these modes the input is sampled through a track/hold with a fixed 2 ns aperture which yields a 16 bit resolutionresult. The sample rate is selectable from 6000 sec/sample to 20 µs/sample with 100 ns resolution. Input voltageranges cover 10 mV peak to 1000 V peak full scale. The input bandwidth is limited to 12 MHz.SSDCSub-Sampling (Effective time sampling) DC Coupled.SSAC Sub-Sampling (Effective time sampling) AC Coupled.These techniques implement synchronous sub-sampling of a repetitive input signal through a track/hold with a 2 nssample aperture which yields a 16 bit resolution result. The effective sample rate is settable from 6000 sec/sampleto 10 ns/sample with 10 ns resolution. Sampled data can be time ordered by the instrument and output to the GPIB.Input voltage ranges cover 10 mV peak to 1000 V peak full scale. The input bandwidth is limited to 12 MHz.Section 7: Digitizing continuedDirect and Sub-sampled Digitizing(DSDC, DSAC, SSDC and SSAC Functions) 2223Section 8: System SpecificationsSection 9: RatioSection 10: Math Functions 24Operating environment0 to 55 °COperating humidity rangeUp to 95% RH at 40 °CPhysical characteristics88.9 mm H x 425.5 mm W x 502.9 mm DNet weight: 12 kg (26.5 lbs)Shipping weight: 14.8 kg (32.5 lbs) IEEE-4888 interfaceComplies with the following:IEEE-488.1 Interface StandardIEEE-728 Codes/Formats StandardHPML (Multimeter Language) Storage temperature–40 to +75 °CWarm-up time4 hours to published specifications Power requirements100/120 V, 220/240 V ± 10%48-66 Hz, 360-420 Hz automaticallysensed< 30 W, < 80 VA (peak)Fused: 1.5 @ 115 V or 0.5 A @ 230 V Designed in accordance withSafety: IEC 348, UL 1244, CSA7n: Classified underMIL-T-28800D as Type III,Class 5, Style E, and Color R.Warranty periodOne yearInput terminalsGold-plated tellurium copperIncluded with 3458A34137A Test lead set for 3458Acalibration certificate25Kelvin probe and clip set Keysight 3458A multimeter Array (with GPIB, 20 k bytes reading memory, and 8 ppm stability)3458A-001 Extended reading memory(Expands total to 148 k bytes)3458A-002 High stability (4 ppm/year) reference3458A-A6J ANSI Z540 compliant calibration3458A-907 Front handles kit (P/N 5063-9226)3458A-908 Rack mount kit (P/N 5063-9212)3458A-909 Rack mount kit with handles (P/N 5063-9219)3458A-ABD German manual3458A-ABF French manual3458A-ABJ Japanese manual3458A-ABZ Italian manualAccessories10833A GPIB cable (1 m)10833B GPIB cable (2 m)10833C GPIB cable (4 m)10833D GPIB cable (0.5 m)11059A Kelvin probe set (4-wires, 1 m)11060A Surface mount device (SMD) test probes11062A Kelvin clip set (2 each)34137A Deluxe test lead set for the 3458A34308A Thermistor kit34330A 30 A current shuntE2308A Thermistor temperature probe26myKeysight/find/mykeysightA personalized view into the information most relevant to you.AdvancedTCA® Extensions for Instrumentation and Test (AXIe) is anopen standard that extends the AdvancedTCA for general purpose and semiconductor test.
