Up to 8 channels of high resolution With the PicoScope 4000A Series providing a choice of either 2, 4 or 8 highresolution analog channels you can easily view audio, ultrasonic, vibration and power waveforms, analyze timing of complex systems, and perform a wide range of precision measurement tasks on multiple inputs at the same time. The scopes have a small, compact footprint, yet the BNC connectors with a minimum 20 mm spacing still accept all common probes and accessories. Despite their compact size, there is no compromise on performance. With a high vertical resolution of 12 bits, 20 MHz...

Power measurements The PicoScope 4000A Series is ideal for making a range of power measurements on high voltages and currents and low-voltage control signals. For the best results, use a Pico differential voltage probe (TA041 or TA057) in combination with a current clamp (TA167) or probes (TA167, TA325 or TA326). To improve the efficiency and reliability of power designs, the scope can display and analyze standby power dissipation, inrush current, and steady-state power consumption. PicoScope’s built-in measurements and statistics of parameters such as true RMS, frequency, peak‑to-peak...

DeepMeasure™ One waveform, millions of measurements. Measurement of waveform pulses and cycles is key to verification of the performance of electrical and electronic devices. DeepMeasure delivers automatic measurements of important waveform parameters, such as pulse width, rise time and voltage. Up to a million cycles can be displayed with each triggered acquisition. Results can be easily sorted, analyzed and correlated with the waveform display. Complex embedded systems When debugging an embedded system with a scope, you can quickly run out of channels. You may need to look at an I2C or...

PicoScope performance and reliability With over 25 years’ experience in the test and measurement industry, we know what’s important in an oscilloscope. The PicoScope 4000A Series delivers value for money by including a wide range of high-end features as standard. The PicoScope 6 software includes serial decoding and mask limit testing, and new functionality is regularly delivered through free upgrades to ensure that your device does not quickly become outdated. All Pico Technology devices are optimized with the help of feedback from our customers. Zoom in and capture every last detail The...

Math channels With PicoScope 6 you can perform a variety of mathematical calculations on your input signals and reference waveforms. Use the built-in list for simple functions such as addition and inversion, or open the equation editor and create complex functions involving trigonometry, exponentials, logarithms, statistics, integrals and derivatives, filters, averaging and peak-detection. Spectrum analyzer With the click of a button, you can open a new window to display a spectrum plot of selected channels up to the full bandwidth of the oscilloscope. A comprehensive range of settings...

Automatic measurements PicoScope allows you to display a table of automated measurements for troubleshooting and analysis: 15 scope and 11 spectrum mode measurements are available. 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. Each measurement includes statistical parameters showing its variability. For information on the measurements available in scope and spectrum modes, see Automatic Measurements in the Specifications...

Serial decoding The PicoScope 4000A Series includes serial decoding capability across all channels as standard. PicoScope software can decode 1-Wire, ARINC 429, CAN, DALI, DCC, DMX512, Ethernet 10Base-T, FlexRay, I²C, I²S, LIN, Manchester, Modbus ASCII, Modbus RTU, PS/2, SENT, SPI, and UART protocol data as standard, with more protocols in development and available in the future with free-of-charge software upgrades. The decoded data can be displayed in the format of your choice: in graph, in table, or both at once. • Graph format shows the decoded data beneath the waveform on a common time...

High signal integrity Careful front-end design and shielding reduce noise, crosstalk and harmonic distortion, meaning we are proud to publish the specifications for our scopes in detail. Decades of oscilloscope design experience can be seen in improved pulse response and bandwidth flatness, and low distortion. The scope features 12 input ranges from ±10 mV to ±50 V full scale and a huge spurious free dynamic range of up to 70 dB. The result is simple: when you probe a circuit, you can trust in the waveform you see on the screen. High-end features as standard Buying a PicoScope is not like...

Digital triggering Most digital oscilloscopes still use an analog trigger architecture based on comparators. This can cause time and amplitude errors that cannot always be calibrated out. The use of comparators often limits the trigger sensitivity at high bandwidths and can also create a long trigger rearm delay. In 1991 Pico set an innovation milestone by pioneering the use of full digital triggering using the actual digitized data. This reduces trigger errors and allows our oscilloscopes to trigger on the smallest signals, even at the full bandwidth. All real-time triggering is digital,...

Mask limit testing PicoScope allows you to draw a mask around any signal, in either the scope view or the spectrum view, with user-defined tolerances. This has been designed specifically for production and debugging environments, enabling you to compare signals. Simply capture a known good signal, draw a mask around it, and then attach the system under test. PicoScope will capture any intermittent glitches and can show a failure count and other statistics in the Measurements window. The numerical and graphical mask editors can be used separately or in combination, allowing you to enter...
