Attention all
Automotive Scope Users

Pico Automotive Scope software now sports a new Waveform Library browser.
Must own PicoScope to view.
See details here


Serial Decoding - UPDATE

The new PicoScope beta release, 6.13, adds Modbus RTU and ASCII to its growing list of serial decoders. Modbus is used in industrial automation to communicate with programmable logic controllers (PLCs).

PicoScope 6 now supports a total of 18 serial protocols and is the only oscilloscope that can decode Modbus.


You can use PicoScope to decode data from a serial bus such as CAN bus. Unlike a conventional bus analyzer, PicoScope lets you see the high-resolution electrical waveform at the same time as the data. RS232/UART and SPI formats added to serial decoding mode
