Trigger on UART pattern
« on: June 03, 2023, 07:46:26 pm »
Hello all,

I’m in the market for a new scope which has the capability of triggering (and decoding) on a UART pattern. Like most lower entry scopes, my Rigol 2000 series scope will only allow for a single data byte for triggering. I would like to be able to trigger on a string of data. A minimum of 10-20 bytes would be nice. It doesn’t look like the Rigols or Siglents have the multi-byte trigger capability. I did find a high-end Agilent 9000 series, but they are way out of my budget which under $2k.

wouldn't take many line of code to do as an addon with cheap micro connected to ext-trig

We actually support multi-byte UART triggering on all of our oscilloscopes, but even our entry level RTB2000 oscilloscope with the UART option (K2) lists at about 2500 USD.

Edit: the RTB only supports patterns up to 4 bytes.

I thought about that and may end up with that approach in the interim. Just wanted to check if any scopes had this feature before upgrading mine.

Thanks!
