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
The PicoScope 3000 range of PC oscilloscopes offer a level of performance that exceeds any other PC oscilloscope currently manufactured by Pico or our competitors.

* In normal operation the PicoScope 320x is powered either from a USB port on your computer or from a powered hub. It is not possible to power this device from an un-powered USB hub. If both the PC and the device under test are referenced to the same ground (earth) then noise/offset problems may occur. This problem is only likely to occur when using a mains powered desktop PC whilst measuring DC coupled (earth referenced) signals of a small amplitude. If this situation occurs a mains power adaptor (supplied) will have to be used to power the unit.
