Pico Technology has released a new range of PicoScope 2000 oscilloscopes that occupy roughly the area of a passport and are only 19 mm thick.
Connected to and powered from a USB port, they offer bandwidths up to 200 MHz and feature an arbitrary waveform generator, yet are almost 80% smaller than the previous generation of PicoScopes. This makes them ideal for engineers on the move to keep in their laptop bag, while offering features and performance of a traditional benchtop oscilloscope.
The new range was very much a ‘skunkworks’ project, according to managing director Alan Tong. “We give all of our engineers one afternoon a week to work on a project of their own choosing, and a group decided to see how small they could make an oscilloscope without compromising on performance.
“They kept the project secret until they had a working prototype complete with a 3D-printed enclosure. When I saw it I was immediately sold on the idea, as it was a product I wanted to own myself. It’s so small and light, I now carry an oscilloscope in my laptop bag all the time.”
The specifications include a maximum sampling rate of 1 GSps, adjustable analog offset over the full input range, and high-speed USB streaming up to 1 MSps for waveform captures of up to 100 million samples in length. The built-in signal source can act as a standard signal generator (sine, square, triangle and others) with programmable sweep or as a 12-bit, 20 MSps full-function arbitrary waveform generator.
Despite their small size, the dual channel scopes include an impressive list of features as standard, including an FFT spectrum analyser, up to 48K samples of segmented memory for rapid captures, math channels, automatic measurements, colour persistence display mode, advanced digital triggering, mask limit testing and serial decoding (CAN bus, LIN bus, FlexRay, SPI, I²C, I²S, UART).
A free SDK with example code is available for developing applications in languages such as C, Microsoft Visual Basic, National Instruments LabVIEW and MathWorks MATLAB.
