The Picoscope 3000D oscilloscopes offer a maximum real-time sampling rate of 1 Gsample/sec and feature a USB 3.0 interface; they also host a built-in AWG (arbitrary waveform generator). Deep memory enables long timebases with the fastest sampling rates; for example, at 1 Gsample/s sampling rate, you can capture a 500 msec waveform—that’s half a billion samples, Pico points out—while hardware acceleration keeps the display updating smoothly.

The 512 Msample buffer memory can be segmented, enabling acquisition of up to 10,000 individual waveform segments of 50,000 samples, with less than 1 µs re-arm time between each segment. You can set the PicoScope to trigger on each packet and skip the gaps that are of no interest. This function lets you acquire, for instance, CAN data packets over several minutes and then analyze the packet content at a later point in time.

The oscilloscopes are multi-function include a spectrum analyser and AWG, and advanced functions include serial-bus decoding, mask-limit testing, math channels, and filtering. Advanced triggers include pulse width, interval, window, window pulse width, level dropout, window dropout, runt pulse, variable hysteresis, and logic. All triggering is digital, ensuring low jitter and single-LSB voltage resolution. MSO (mixed-signal oscilloscope) models combine these triggers with edge and pattern triggering on the digital inputs. Other built-in features include color persistence display modes, automatic measurements with statistics, programmable alarms, and decoding of I²C, UART/RS232, SPI, CAN bus, LIN, FlexRay and I²S signals.

Software updates include a fast persistence mode that gives updates of around 100,000 waveforms per second, while the math channels have been expanded to include configurable filters.

A free SDK (Software Development Kit) lets you develop custom applications. It includes example programs in C#, C++, Excel, LabVIEW, and MATLAB, and you can use it with any language that supports C calling conventions. The PicoScope software and SDK are compatible with Windows XP or later, with beta versions for Linux and Mac OS X. Beta drivers are also available for the ARM-based Beaglebone Black and Raspberry Pi.
