I am considering buying the Picoscope 3205 MSO, but before I buy it I would like to understand if it meets my requirements. One of the uses will be to use the oscilloscope to debug UART communication protocols (baudrates varying from 31,250 up to 600,000, mostly "non-standard" baudrates.)

While playing around with the PicoSoftware (PicoScope® 6 - PC Oscilloscope software version: 6.6.50.3), I noticed that in the serial decoding option, there exists a dropdown list containing "standard" baudrates upto 115,200. There is no option to enter custom baudrates.

Is it possible to decode these "non-standard" baudrates? If yes, then how could I use the Picoscope 3205 MSO to decode a serial communication at 230,400 baud?

If you select UART decoding on a channel, the software will try and work out the baud rate of the signal it sees. It may pick up your 230,400 baud by default, but if not you will then have the option to enter a setting.

Thanks Martyn! I hadn't realized that one could type in a value in the Serial decoding -> baud rate dropdown box.
