PicoScope 2000 Series 超级紧凑式数字双通道或四通道波形仪和混合信号仪说明书
PicoScope® 2000 SeriesUltra-compact PC oscilloscopes The compact alternative to a benchtop oscilloscope2 or 4 analog channelsMSO models with 16 digital channelsUp to 100 MHz bandwidthUp to 1 GS/s sampling rateUp to 128 MS buffer memoryBuilt-in arbitrary waveform generatorUSB-connected and powered2-channel oscilloscope: 2206B, 2207B and 2208BIntroducing the PicoScope 2000 SeriesThe PicoScope 2000 Series offers you a choice of 2-channel and 4-channeloscilloscopes, plus mixed-signal oscilloscopes (MSOs) with 2 analog + 16 digitalinputs. All models feature a spectrum analyzer, function generator, arbitrary waveform generator and serial bus analyzer, and the MSO models also include a logic analyzer.The PicoScope 2000A models all deliver unbeatable value for money, with excellent waveform visualization and measurement to 25 MHz for a range of analog and digital electronic and embedded system applications. They are ideal for education, hobby and field service use.The PicoScope 2000B models have the added benefits of deep memory (up to 128 MS), higher bandwidth (up to 100 MHz) and faster waveform update rates, giving you the performance you need to carry out advanced analysis of your waveform, including serial decoding and plotting frequency against time.Advanced oscilloscope displayThe PicoScope 6 software takes advantage of the display size, resolution andprocessing power of your PC – in this case displaying four analog signals, a zoomed view of two of the signals (undergoing serial decoding), and a spectrum view of athird, all at the same time. Unlike a conventional benchtop oscilloscope, the size of the display is limited only by the size of your computer monitor. The software is also easy to use on touch-screen devices – you can pinch to zoom and drag to scroll.4-channel oscilloscope2-channel oscilloscope: 2204A and 2205A2+16-channel mixed-signal oscilloscope (MSO)Powerful, portable and super-smallThe PicoScope 2000 Series oscilloscopes are compact enough to fit easily into your laptop bag along with all their probes and leads. These modern alternatives to bulky benchtop devices are ideal for a wide range of applications including design, test, education, service, monitoring, fault-finding and repair, and are perfect for engineers on the move.Fast samplingThe PicoScope 2000 Series oscilloscopes provide fast real-time sampling rates of up to 1 GS/s on the analog channels. This represents a timing resolution of 1 ns.For repetitive analog signals, equivalent-time sampling (ETS) mode can boost the maximum effective sampling rate up to 10 GS/s, allowing even finer resolution down to 100 ps. All scopes support pre-trigger and post-trigger capture using the full memory depth.High-end features as standardBuying a PicoScope is not like making a purchase from other oscilloscope companies, where increased functionality can considerably raise the price. PicoScopes are all-inclusive instruments, with no need for expensive upgrades to unlock the hardware. Other advanced features such as resolution enhancement, mask limit testing, serial decoding, advanced triggering, automatic measurements, math channels (including the ability to plot frequency and duty cycle against time), XY mode and segmented memory are all included in the price.FlexibilityThe PicoScope software offers a breadth of advanced features with a user-friendly interface. As well as the standard Windows installation, PicoScope Beta software also works effectively on Linux and macOS operating systems, giving you the freedom to operate your PicoScope from your chosen platform.Unique commitment to product supportYour PicoScope gets better the longer you use it, thanks to the regular free updates we supply for both the PC software and the oscilloscope firmware throughout the life of the product. The performance and functionality of the scope both keep improving, without you paying a penny more than the purchase price.This level of support, combined with the personal service provided by our technical and sales support teams, is reflected in consistently excellent customer feedback.High signal integrityAt Pico Technology we’re proud of the dynamic performance of our products. Careful front-end design and shielding reduce noise, crosstalk and harmonic distortion. Decades of oscilloscope design experience can be seen in improved pulse response and bandwidth flatness.The result is simple: when you probe a circuit, you can trust in the waveform you see on the B connectivityThe USB connection makes printing, copying, saving, and emailingyour data from the field quick and easy. The high-speed USBinterface allows fast data transfer, while USB powering removesthe need to carry around a bulky external power supply.Deep capture memoryPicoScope 2000 Series ‘B’ models have waveform capture buffers ranging from 32 to 128 megasamples – many times larger than competing scopes. Deep memory enables the capture of long-duration waveforms at maximum sampling speed. In fact, some PicoScope 2000 Series models can capture 100 ms waveforms with 1 ns resolution. In contrast, the same 100 ms waveform captured by an oscilloscope with a 10 megasample memory would have just 10 ns resolution.Deep memory can be useful in other ways too: PicoScope 6 lets you divide the capture memory into a number of segments, up to a maximum of 10 000. You can set up a trigger condition to store a separate capture in each segment, with as little as 1 µs dead time between captures. Once you have acquired the data, you can step through the memory one segment at a time until you find the event you are looking for.Powerful tools are included to allow you to manage and examine all of this data. As well as functions such as mask limit testing and color persistence mode, the PicoScope 6 software enables you to zoom into your waveform by a factor of several million. The Zoom Overview window allows you to easily control the size and location of the zoom area. Other tools, such as the waveform buffer, serial decoding and hardware acceleration work with the deep memory, making the PicoScope 2000 Series some of the best-value oscilloscopes on the market.PicoScope 6 softwareThe PicoScope software display can be as basic or as detailed as you need. Begin with a single view of one channel, and then expand the display to include up to four live channels (model-dependent), plus math channels and reference waveforms. Display multiple scope and spectrum views with automatic or custom layouts and quickly access all the most frequently-used controls from the toolbars, leaving the display clear for your waveforms.Oscilloscope controls: PicoScope’s full analog-domain controls, including zoom, filtering, andfunction generatovr, are all available in MSO digital signal mode.Mixed digital and analog signalsThe PicoScope 2000 MSO models add 16 digital channels to their two analog channels, enabling you to accurately time-correlate analog and digital channels. You can group digital channels together and display them as a bus, with each bus value displayed in hex, binary or decimal, or as a level (for DAC testing). You can set advanced triggers across both the analog and digital channels.The digital inputs also bring extra power to the serial decoding options. You can decode serial data on all analog and digital channels simultaneously, giving you up to 20 channels of data – for example decoding multiple SPI, I²C, CAN bus, LIN bus and FlexRay signals all at the same time.Persistence modePicoScope 6 persistence mode options allow you to see old and new data superimposed, with newer waveforms drawn in a brighter color or deeper shade. This makes it easy to spot glitches and dropouts and estimate their relative frequency – useful for displaying and interpreting complex analog signals such as video waveforms and analog modulation signals.The PicoScope 2000 Series’ hardware acceleration means that, in Fast Persistence mode, waveform update rates of up to 80 000 waveforms per second are achievable. Color-coding or intensity-grading shows which areas are stable and which are intermittent. Choose between analog intensity, digital color and fast display modes or create your own custom setup.Spectrum analyzerThe spectrum view plots amplitude against frequency and is ideal for finding noise, crosstalk or distortion in signals. PicoScope 6 uses a fast Fourier transform (FFT) spectrum analyzer, which (unlike a traditional swept spectrum analyzer) can display the spectrum of a single, non-repeating waveform.With a click of a button, you can display a spectrum plot of the active channels, with a maximum frequency of up to 200 MHz. A comprehensive range of settings gives you control over the number of spectrum bins, window functions, scaling (including log/log) and display mode (instantaneous, average or peak-hold).Display multiple spectrum views with different channel selections and zoom factors, and place these alongside time-domain views of the same data. Choose froma number of automatic frequency-domain measurements to add to the display, including THD, THD+N, SNR, SINAD and IMD. You can apply mask limit testing to a spectrum and can even use the AWG and spectrum mode together to perform sweptscalar network analysis.Serial decoding and analysisThe PicoScope 2000 Series oscilloscopes include serial decoding capability as standard. The PicoScope 6 software has support for 20 protocols including I2C, SPI, CAN, RS-232, Manchester and DALI. Decoding helps you see what is happening in your design to identify programming and timing errors and check for other signal integrity issues. Timing analysis tools help to show the performance of each design element, identifying parts of the design that need to be improved to optimize overall system performance.You can capture and decode several protocols at a time, in any combination, the only limit being the number of available channels – 18 for MSO models, as you can decode serial data on all analog and digital inputs simultaneously. The ability to observe data flow across a bridge (such as CAN bus in, LIN bus out) is incredibly powerful. The deep memory of the PicoScope 2000B models makes them ideal for serial decoding, as they can handle many thousands of frames of data.GRAPH FORMAT shows the decoded data (in hex, binary, decimal or ASCII) in a timing diagram format, beneath the waveform on a common time axis, with error frames marked in red. You can zoom in on these frames toinvestigate noise or distortion, and eachpacket field is assigned a different color,so the data is easy to read.TABLE FORMAT shows a list of thedecoded frames, including the data andall flags and identifiers. You can set upfiltering conditions to display only theframes you are interested in or search forframes with specified properties.The statistics option reveals more detailabout the physical layer such as frametimes and voltage levels. PicoScope 6 canalso import a spreadsheet to decode thedata into user-defined text strings.Waveform buffer and navigatorEver spotted a glitch on a waveform, but by the time you’ve stopped the scope it’s gone? With PicoScope you no longer need to worry about missing glitches or other transient events, as it can store the last 10 000 waveforms in its circular waveform buffer.The buffer navigator provides an efficient way of navigating and searching through waveforms, effectively letting you turn back time. When carrying out a mask limit test, you can also set the navigator to show only mask fails, enabling you to find any glitches quickly.Mask limit testingMask limit testing allows you to compare live signals against known good signals, and is designed for production and debugging environments. Simply capture a known good signal, generate a mask around it and then use the alarms to automatically save any waveform (complete with a time stamp) that violates the mask. PicoScope 6 will capture any intermittent glitches and show a failure count in the Measurements window (which you can still use for other measurements). You can also set the waveform buffer navigator to show only mask fails, enabling you to find any glitches quickly.Mask files are easy to edit (numerically or graphically), import and export, and you can simultaneously run mask limit tests on multiple channels and in multiple viewports.AlarmsYou can program PicoScope 6 to execute actions when certain events occur.The events that can trigger an alarm include mask limit fails, trigger events and buffers full.PicoScope 6 actions include saving a file, playing a sound, executing a program and triggering the arbitrary waveform generator.Automatic measurementsPicoScope allows you to automatically display a table of calculated measurements for troubleshooting and analysis. Using the built-in measurement statistics you can see the average, standard deviation, maximum and minimum of each measurement as well as the live value.You can add as many measurements as you need on each view – 18 differentmeasurements are available in scope mode and 11 in spectrum mode. For information on these measurements, see Automatic Measurements in the Specificationstable.Scope modeSpectrum modeArbitrary waveform and function generatorAll PicoScope 2000 Series oscilloscopes have a built-in function generator and arbitrary waveform generator (AWG). The function generator can produce sine, square, triangle and DC level waveforms, and many more besides, while the AWG allows you to import waveforms from data files or create and modify them using the built-in graphical AWG editor.As well as level, offset and frequency controls, advanced options allow you to sweep over a range of frequencies. Combined with the advanced spectrum mode, with options including peak hold, averaging and linear/log axes, this creates a powerful tool fortesting amplifier and filter responses.Advanced triggersThe PicoScope 2000 Series offers an industry-leading set of advanced triggers including pulse width, windowed and dropout.The digital trigger available on MSO models allows you to trigger the scope when any or all of the 16 digital inputs match a user-defined pattern. You can specify a condition for each channel individually, or set up a pattern for all channels at once using a hexadecimal or binary value.You can also use the logic trigger to combine the digital trigger with an edge or window trigger on any of the analog inputs, for example to trigger on data values in a clocked parallel bus.Digital triggering architectureIn 1991, Pico Technology pioneered the use of digital triggering and precision hysteresis using theactual digitized data. Traditionally, digital oscilloscopes have used an analog trigger architecture based on comparators, which can cause time and amplitude errors that cannot always be calibrated out. Additionally, the use of comparators can often limit the trigger sensitivity at high bandwidths and can create a long trigger rearm delay.Pico’s technique of fully digital triggering reduces trigger errors and allows our oscilloscopes to trigger on the smallest signals, even at the full bandwidth, so you can set trigger levels and hysteresis with high precision and resolution.The digital trigger architecture also reduces the rearm delay. Combined with the segmented memory, thisenables you to use rapid triggering to capture 10 000 waveforms in 10 ms in 8-bit mode.Custom probesThe custom probes feature allows you to correct for gain, attenuation, offsets and nonlinearities in probes, transducers and other sensors, and to measure quantities other than voltages (such as current, power or temperature).Definitions for standard Pico-supplied probes are built in, but you can also create your own using linear scaling or even an interpolated data table, and save them for later use.Math channels and filtersWith PicoScope 6 you can perform a variety of mathematical calculations on your inputsignals and reference waveforms. Select simple functions such as addition and inversion,or open the equation editor to create complex functions involving filters (lowpass,highpass, bandpass and bandstop filters), trigonometry, exponentials, logarithms,statistics, integrals and derivatives.Display up to eight real or calculated channels in each scope view. If you run out ofspace, just open another scope view and add more. You can also use math channels toreveal new details in complex signals, for example graphing the changing duty cycle orfrequency of your signal over time.Plot frequency against time with PicoScope 6All oscilloscopes can measure the frequency of awaveform, but often you need to know how thatfrequency changes over time, which is a difficultmeasurement to make. The freq math function cando exactly this: in this example, the top waveform’sfrequency is being modulated by a ramp function, asplotted in the bottom waveform.A separate math function allows you to plot duty cyclein a similar way.PicoLog ® 6 supportAll PicoScope 2000 Series oscilloscopes are now supported in PicoLog 6, allowing you to view and record signals on multiple units in one capture.PicoLog 6 allows sample rates of up to 1 kS/s per channel, and is ideal for long-term observation of general parameters, such as voltage or current levels, on several channels at the same time. It is less suitable for waveshape or harmonic analysis: use the PicoScope 6 software for these tasks.You can also use PicoLog 6 to view data from your oscilloscope alongside a data logger or other device. For example, you could measure voltage and current with your PicoScope and plot both against temperature using a , or humidity with a DrDAQ multipurpose data logger .PicoLog 6 is available for Windows, macOS and Linux, including Raspbian.PicoSDK ® – write your own appsOur software development kit, PicoSDK, allows you to write your own software and includes drivers for Windows, macOS and Linux. Example code supplied on our GitHub organization page shows how to interface to third-party software packages such as National Instruments LabVIEW and MathWorks MATLAB.Amongst other features, the drivers support data streaming, a mode that captures continuous gap-free data directly to your PC at rates of up to 125 MS/s, so you are not limited by the size of your scope’s capture memory. Sampling rates in streaming mode are subject to PC specifications and application loading.There is also an active community of PicoScope 6 users who share both code and whole applications on our Test and Measurement Forum and the PicoApps section of the website. The Frequency Response Analyzer shown here is one of the most popular of theseapplications.20-way 25 cm digital MSO cableMSO test clipsKit contents and accessoriesThe PicoScope 2000 Series oscilloscope kit contains the following items:• USB 2.0 (USB 3.0/3.1 compatible) cable• Two or four x1/x10 passive probes (except kits specified as without probes)• Digital input cable (MSO models only)• 20 logic test clips (MSO models only)•Quick Start GuideProbes, cables and clipsYour PicoScope 2000 Series oscilloscope kit comes with probes trimmed to match the performance of your oscilloscope.MSO models are also supplied with an MSO cable and 20 test clips.Oscilloscope probeQuick product selector Array 2-channel oscilloscopes4-channel oscilloscopesMixed-signal oscilloscopes2 analog + 16 digital inputsUsers writing their own apps can find example programs for all platforms on the Pico Technology organization page on .Ordering informationPP906PicoScope 2204A10 MHz 2-channel oscilloscopePP966PicoScope 2205A-D225 MHz 2-channel oscilloscope without probesPP907PicoScope 2205A25 MHz 2-channel oscilloscopePQ012PicoScope 2206B50 MHz 2-channel oscilloscopePQ013PicoScope 2207B70 MHz 2-channel oscilloscopePQ014PicoScope 2208B100 MHz 2-channel oscilloscopePQ015PicoScope 2405A25 MHz 4-channel oscilloscopePQ016PicoScope 2406B50 MHz 4-channel oscilloscopePQ017PicoScope 2407B70 MHz 4-channel oscilloscopePQ018PicoScope 2408B100 MHz 4-channel oscilloscopePQ008PicoScope 2205A MSO25 MHz 2+16 channel mixed-signal oscilloscopePQ009PicoScope 2206B MSO50 MHz 2+16 channel mixed-signal oscilloscopePQ010PicoScope 2207B MSO70 MHz 2+16 channel mixed-signal oscilloscopePQ011PicoScope 2208B MSO100 MHz 2+16 channel mixed-signal oscilloscopeReplacement accessoriesTA136TA136 logic cable20-way 25 cm digital cable (suitable for MSOs only)TA139TA139 test clips Pack of 10 logic test clips (suitable for MSOs only)Calibration service* Prices are correct at the time of publication.
