Vodafone GigaCube (Huawei B528s-23a) In First Test

Vodafone GigaCube (Huawei B528) In First TestTag: Vodafone B528, Huawei B528, Gigacube B528, Vodafone GigaCube B528, Vodafone Cube B528, Huawei B528s-23aVodafone GigaCube (Huawei B528s-23a): https:///huawei-b528-cube-4g-lte-router.htmlLast month, Vodafone has presented the GigaCube for a package of routers and mobile phone rates. The router is the Huawei B528, which is also without Vodafone branding. Only the outer packaging carries the design of the telecommunication service provider. The GigaCube itself has the manufacturer Huawei's logo and there is no indication of Vodafone. Now we have the opportunity to have closer look at the GigaCube router.Not suitable for mobile useThe Vodafone GigaCube is 105 x 105 x 181 millimeters in size. The body is not in small size, so you may not take it in hand like Huawei E5787 mobile WiFi hotspots. For this reason alone, the GigaCube is not suitable for mobile use, but it’s cool for the weekend house, the caravan, the hotel room or the apartment. In addition, there is no inserted battery or replacable battery in the Huawei B528 GigaCube. Instead, the unit is powered only by the included power supply.As an alternative to WLAN, a notebook can also be connected to the router via a network cable. Such a cable is included with the GigaCube. The connector is located on the back of the device. There is also the socket with which the power supply is connected to the mobile hotspot. Under one flap there are also jacks, via which external antennas can be connected to the GigaCube. The connection for a VoIP telephone, which is also located on the back of the router, has been deactivated according to Vodafone specifications. We could not test this so far.On the front, we can see not only the on/off switch and the WPS button, but also four light-emitting diodes. These indicate whether the B528 GigaCube is powered, whether the WLAN hotspot is available and whether the LAN port is being used. The fourth LED indicates whether the router is connected to the mobile network.Easy SetupThe GigaCube can be configured via a connected computer, a smartphone or a tablet. The Internet address to configure the router is giga.cube, user need enter it in the Internet browser. The default password for the web front-end is located on the bottom of the router. Here is also the SSID and WLAN password specified. In addition, the SIM card (micro SIM format) slot is located on the underside.After the SIM card is inserted directly and the GigaCube is switched on, the LED for the mobile radio reception is initially red. Reason: The SIM PIN must be entered via the web-based menu if the PIN search on the SIM card has not been switched off, which is at least partly the case with the operator cards defined for the GigaCube. After this, the initial setting can be made. A personalized SSID can be assigned, which can be connected with a special password.On page 2, you can read about the function in the configuration menu, and to what extent, the GigaCube also allows the use of SIM cards from other networks. During the initial setup, the access data for the router menu can also be adjusted. In addition to own WLAN data for the hotspot on 2.4 GHz, the individualization for 5 GHz is also integrated. The settings can be changed subsequently. Furthermore, the user can decide whether to operate parallel to 2.4 and 5 GHz or only on one of these frequency ranges. In principle, the WLAN function can also be switched off completely if, for example, only a device via a network cable is connected to the router for the Internet access.SIM free & UnlockedWe have also used a SIM card from other network provider such as O2, which has worked smoothly in the GigaCube. Say: The Vodafone GigaCube router was not equipped with a SIM lock or Netlock and it can be used with any operator cards. The access data for foreign networks may not be recognized automatically.To do this, a new profile must only be created in the Connection Setup - Profile Management menu.What Interesting is the possibility to set up a VPN directly on the Huawei B528 router. The WLAN channels can be selected manually. These are automatically assigned by default. The user interface is very similar to Huawei's other mobile hotspots. The WLAN range is significantly higher than the Huawei E5776 mobile hotspot, which we had tested for comparison.Fast Wireless Internet ConnectionThe GigaCube supports speeds of up to 300 MBit/s in the downstream via LTE, especially on the LTE-Advanced networks. Also Internet connections can be established with the router via UMTS/HSPA and GPRS/EDGE. In the first test, the Huawei B528 sold by Vodafone GigaCube left a good impression. The setup is intuitively possible (can be seen from the fact that the access data for the 5 GHz, WLAN area must be adjusted later) and the WiFi range is quite comparable to that of a FRITZ! Box 7490, which we had tested at the same Place.The Vodafone GigaCube could serve as a DSL replacement, but less suitable for the more extensive file exchange and intensive streaming. Exciting is the possibility to use any SIM card. Thus, the Huawei B528 GigaCube can also be bought at the comparatively low price from , for example on a holiday abroad, where the GigaCube tariff is not available, can also be used with a local SIM card. And there is newer model Huawei B618 LTE CPE Cube available now, which supports higher level LTE networks.If you would like to know more Huawei 4G LTE Routers, welcome to checkhttps:///4g-wireless-router/huawei-4g-lte-wifi-router.html。

Fluke Calibration 8588A 8558A数字多功能仪器说明书

The 8588A Reference Multimeter is the world’s most stable digitizing multi-meter. Designed for calibration laboratories, this long-scale high-precision reference multi-meter features superior accuracy and long-term stability over a wide measurement range, with an intuitive user interface and a color display.The 8588A delivers reliable and reproducible measurements with exceptional performance suitable for primary levellaboratories. With more than 12 measurement functions, includ-ing the new digitize voltage, digitize current, capacitance, RF power, and external shunts for dc and ac current, the 8588A helps you consolidate your lab’s cost of test into a single mea-surement instrument. Its superb analog performance is aug-mented by Fluke Calibration’s new high-speed system design and the industry’s fastest direct digitizing capability, enabling significant throughput increase for many automated systems demanding a combination of the highest speed and best accuracy.The 8588A holds the indus-try’s best one-year dc voltage accuracy of 2.7 uV/V at 95 % confidence interval, or3.5 uV /V at 99 %, and best 24-hour stability of 0.5 uV/V (95 %) or 0.65 uV/V (99 %),enabling it to outperform other long-scale reference multimeters on the market. The 8588A fur-ther pushes the speed envelope by producing a stable 8.5 digits reading in a mere one second.The 8588A platform consists of two models. The 8588A and 8558A both feature a common intuitive user interface with an easy-to-navigate menu struc-ture for all configurations and a set of matching SCPI-compliantcommands for automated envi-ronments.

This best-in-class long-scale digital reference multimeter guarantees superior 3.5 ppm one-year dc voltage relative accuracy at99 % confidence level and long-term stability over awide measurement range and functions.The 8588A contains the world’s most stable voltage references and attenuators custom crafted at Fluke Cali-bration. These precision components eliminate the need for daily internal self-calibration to compensate for drift when less-precise components are used. Autozeroing also becomes unnecessary because the ampli-fier offsets are ultra-stable. The 8588A achieves an exceptional 8.5-digit resolution reading in one second, two times shorter than the next best in class, which amounts to considerable productivity improvements.The 8588A is easy and intui-tive to use. It is the ideal lab multimeter for metrologists and calibration laboratory manag-ers who expect and appreciate a straightforward setup that quickly achieves the maximum performance of the instrument.• 3.5 µV/V (99 %), 1 year relative accuracy, dc voltage, without internal self-calibra-tion or auto-adjustments • 0.65 µV/V (99 %), 24 hour stability, dc voltage• 9 µΩ/Ω (99 %), 1 year, resistance• 2.02x full scale stretches lower noise floor to higher signal levels to maximize higher accuracies from the instrument• 0 ns to 100 s aperture setting allows the industry’s widest flexibility to control data capture window Accuracy, offset andstability provide excellentac performanceThe 8588A provides the mostaccurate true ac rms mea-surement available in a FlukeCalibration multimeter.With a 5 mega-sam-ples-per-second samplinganalog-to-digital converterand an extraordinarily stabledc analog path, the 8588Aachieves remarkable ac rmsmeasurement performance thatis ten times faster, two timesless noisy, and more sensitivefor low level signals than otherinstruments in this class. Itutilizes digital rms calculationsto maintain full resolution of awide dynamic range of digitizedsignals.Rapid digital filters are moreeffective than their analogequivalents for faster settling.The digital filters eliminate thedielectric absorption on analogfilters, commonly associatedwith residual slow-tail char-acteristics. The digital filterseffectively shorten settling timeto within 6 cycles of the filterfrequency and less than 1 ppmof the fully settled value. This isup to 10 times faster than otherlong-scale precision digital mul-timeters at low frequencies.Low noise is achieved fromaveraging the collected high-resolution digitized data andthe inherently stable signalpath. De-coupling low levelsignal sensitivity from tempera-ture drift enables the 8588A tomake high accuracy low-levelac measurements. Therefore,temperature drift, offsets, andlong-term instability typicallyassociated with an analog rmsconverter are eliminated.• 77 µV/V (99 %), 1 yearrelative accuracy, for themost accurate ac voltagemeasurement• 323 µA/A (99 %), 1 yearrelative accuracy, ac current• 15 ms settling time at1 kHz ac filter accom-plishes 10x faster ac voltagemeasurement• 2.02x full scale Vpp, 1.2x fullscale Vrms• Up to 30 A for peak accurrent greatly extends accurrent measurement rangeAC voltage measurementAC voltage measurement settingsSoft menu keysLarge, bright full color display30 A terminal™ terminalsThe intuitive user interface and ﬂatmenu structure makes it easy to access conﬁgurations and view trend plots,waveforms, FFT, histogram and statistics.easy to learn.Enables industry's widest current measurement range through a single terminal.Multi-language selectionChoice of English, Chinese, French,Japanese, Korean, Russian and Spanish.and easily to a ﬂash drive.Run/Stop triggerToggles the continuous, or free run, measurement state.easily to a ﬂash drive.Usability designed for metrologists by metrologistsThe 8588A is the ideal lab multimeter.

LF198/LF298/LF398,LF198A/LF398A Monolithic Sample-and-Hold CircuitsGeneral DescriptionThe LF198/LF298/LF398are monolithic sample-and-hold circuits which utilize BI-FET technology to obtain ultra-high dc accuracy with fast acquisition of signal and low droop rate.Operating as a unity gain follower,dc gain accuracy is 0.002%typical and acquisition time is as low as 6µs to 0.01%.A bipolar input stage is used to achieve low offset voltage and wide bandwidth.Input offset adjust is accom-plished with a single pin,and does not degrade input offset drift.The wide bandwidth allows the LF198to be included in-side the feedback loop of 1MHz op amps without having sta-bility problems.Input impedance of 1010Ωallows high source impedances to be used without degrading accuracy.P-channel junction FET’s are combined with bipolar devices in the output amplifier to give droop rates as low as 5mV/min with a 1µF hold capacitor.The JFET’s have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities.The overall design guarantees no feed-through from input to output in the hold mode,even for input signals equal to the supply voltages.Featuresn Operates from ±5V to ±18V supplies n Less than 10µs acquisition timen TTL,PMOS,CMOS compatible logic input n 0.5mV typical hold step at C h =0.01µF n Low input offsetn 0.002%gain accuracyn Low output noise in hold moden Input characteristics do not change during hold mode n High supply rejection ratio in sample or hold n Wide bandwidthn Space qualified,JM38510Logic inputs on the LF198are fully differential with low input current,allowing direct connection to TTL,PMOS,and CMOS.Differential threshold is 1.4V.The LF198will operate from ±5V to ±18V supplies.An “A”version is available with tightened electrical specifications.Typical Connection and Performance CurveFunctional DiagramDS005692-32Acquisition TimeDS005692-16DS005692-1July 2000LF198/LF298/LF398,LF198A/LF398A

occur.Operating Ratings indicate conditions for which the device is functional,but do not guarantee specific performance limits.Note 2:The maximum power dissipation must be derated at elevated temperatures and is dictated by T JMAX ,θJA ,and the ambient temperature,T A .The maximum allowable power dissipation at any temperature is P D =(T JMAX −T A )/θJA ,or the number given in the Absolute Maximum Ratings,whichever is lower.The maximum junction temperature,T JMAX ,for the LF198/LF198A is 150˚C;for the LF298,115˚C;and for the LF398/LF398A,100˚C.Note 3:Although the differential voltage may not exceed the limits given,the common-mode voltage on the logic pins may be equal to the supply voltages without causing damage to the circuit.For proper logic operation,however,one of the logic pins must always be at least 2V below the positive supply and 3V above the nega-tive supply.Note 4:See AN-450“Surface Mounting Methods and their effects on Product Reliability”for other methods of soldering surface mount devices.Note 5:These parameters guaranteed over a supply voltage range of ±5to ±18V,and an input range of −V S +3.5V ≤V IN ≤+V S −3.5V.Note 6:Hold step is sensitive to stray capacitive coupling between input logic signals and the hold capacitor.1pF,for instance,will create an additional 0.5mV step with a 5V logic swing and a 0.01µF hold capacitor.Magnitude of the hold step is inversely proportional to hold capacitor value.Note 7:Leakage current is measured at a junction temperature of 25˚C.The effects of junction temperature rise due to power dissipation or elevated ambient can be calculated by doubling the 25˚C value for each 11˚C increase in chip temperature.Leakage is guaranteed over full input signal range.Note 8:A military RETS electrical test specification is available on request.The LF198may also be procured to Standard Military Drawing #5962-8760801GA or to MIL-STD-38510part ID JM38510/12501SGA.Typical Performance CharacteristicsNote

pin8LF198/LF298/LF398,LF198A/LF398A5Logic Input Configurations(Continued)Application HintsHold CapacitorHold step,acquisition time,and droop rate are the major trade-offs in the selection of a hold capacitor value.Size and cost may also become important for larger e of the curves included with this data sheet should be helpful in se-lecting a reasonable value of capacitance.Keep in mind that for fast repetition rates or tracking fast signals,the capacitor drive currents may cause a significant temperature rise in the LF198.A significant source of error in an accurate sample and hold circuit is dielectric absorption in the hold capacitor.A mylar cap,for instance,may “sag back”up to 0.2%after a quick change in voltage.A long sample time is required before the circuit can be put back into the hold mode with this type of capacitor.Dielectrics with very low hysteresis are polysty-rene,polypropylene,and Teflon.Other types such as mica and polycarbonate are not nearly as good.The advantage of polypropylene over polystyrene is that it extends the maxi-mum ambient temperature from 85˚C to 100˚C.Most ce-ramic capacitors are unusable with >1%hysteresis.Ce-ramic “NPO”or “COG”capacitors are now available for 125˚C operation and also have low dielectric absorption.For more exact data,see the curve Dielectric Absorption Error.The hysteresis numbers on the curve are final values,taken after full relaxation.The hysteresis error can be significantlyreduced if the output of the LF198is digitized quickly after the hold mode is initiated.The hysteresis relaxation time constant in polypropylene,for instance,is 10—50ms.If A-to-D conversion can be made within 1ms,hysteresis error will be reduced by a factor of ten.DC and AC ZeroingDC zeroing is accomplished by connecting the offset adjust pin to the wiper of a 1k Ωpotentiometer which has one end tied to V +and the other end tied through a resistor to ground.The resistor should be selected to give ≈0.6mA through the 1k potentiometer.AC zeroing (hold step zeroing)can be obtained by adding an inverter with the adjustment pot tied input to output.A 10pF capacitor from the wiper to the hold capacitor will give ±4mV hold step adjustment with a 0.01µF hold capacitor and 5V logic supply.For larger logic swings,a smaller capacitor (<10pF)may be used.Logic Rise TimeFor proper operation,logic signals into the LF198must have a minimum dV/dt of 1.0V/µs.Slower signals will cause ex-cessive hold step.If a R/C network is used in front of theCMOS7V ≤V LOGIC (Hi State)≤15VDS005692-35Threshold =0.6(V

delay,calculate the slope of the wave-form at the threshold point to ensure that it is at least 1.0V/µs.Sampling Dynamic SignalsSample error to moving input signals probably causes more confusion among sample-and-hold users than any other pa-rameter.The primary reason for this is that many users make the assumption that the sample and hold amplifier is truly locked on to the input signal while in the sample mode.In ac-tuality,there are finite phase delays through the circuit creat-ing an input-output differential for fast moving signals.In ad-dition,although the output may have settled,the hold capacitor has an additional lag due to the300Ωseries resis-tor on the chip.This means that at the moment the“hold”command arrives,the hold capacitor voltage may be some-what different than the actual analog input.The effect of these delays is opposite to the effect created by delays in the logic which switches the circuit from sample to hold.For ex-ample,consider an analog input of20Vp-p at10kHz.Maxi-mum dV/dt is0.6V/µs.With no analog phase delay and100 ns logic delay,one could expect up to(0.1µs)(0.6V/µs) =60mVerror if the“hold”signal arrived near maximum dV/dt of the input.A positive-going input would give a+60mV er-ror.Now assume a1MHz(3dB)bandwidth for the overall analog loop.This generates a phase delay of160ns.If the hold capacitor sees this exact delay,then error due to analog delay will be(0.16µs)(0.6V/µs)=−96mV.Total output error is+60mV(digital)−96mV(analog)for a total of−36mV.To add to the confusion,analog delay is proportioned to hold capacitor value while digital delay remains constant.A family of curves(dynamic sampling error)is included to help esti-mate errors.A curve labeled Aperture Time has been included for sam-pling conditions where the input is steady during the sam-pling period,but may experience a sudden change nearly coincident with the“hold”command.This curve is based on a1mV error fed into the output.A second curve,Hold Settling Time indicates the time re-quired for the output to settle to1mV after the“hold”com-mand.Digital FeedthroughFast rise time logic signals can cause hold errors by feeding externally into the analog input at the same time the amplifier is put into the hold mode.To minimize this problem,board layout should keep logic lines as far as possible from the analog input and the C h pin.Grounded guarding traces may also be used around the input line,especially if it is driven from a high impedance source.Reducing high amplitude logic signals to2.5V will also help.Guarding TechniqueDS005692-5Use10-pin layout.Guard around C h is tied to output.LF198/LF298/LF398,LF198A/LF398A7Typical ApplicationsX1000Sample&HoldDS005692-39*For lower gains,the LM108must be frequency compensatedSample and Difference

变态面试题，世界上98%人答不出

爱因斯坦在20世纪初出的这个谜语。他说世界上有98％的人答不出来。某家公司在面试应聘者时借用了爱因斯坦的这个IQ题，考查应聘者的IQ，现在我们暂且不去讨论这个公司用这样的题目来考查应聘者的IQ有多“变态”，如果是你，拿到了这样的笔试题目，你能做得出来吗？
你能做出来吗？做得出来算你牛!
