RF out2 not working on 125-14 boards

[WayneCrump]

Hello

We have two 125-14 v1.1 boards which both seem to have the output 2 not working. If it was just one board I would assume the output to be broken, but both our boards have the same issue which makes me suspect it might be something software related.

I have been using the oscilloscope program to try to set the output. I have used operating systems STEMlab 125-14 1.04-18 and 1.04-28 as well as trying RedPitaya OS 2.0 version 30. I also tried using the C api to set the output as well using the generate_continous.c program and changing the channel number. Channel 1 out works for both boards but not channel 2 out.

I don't have any ideas of what else to try at this moment so it would be nice to have some help.

Thanks.

To be completely sure that it is not software-related please do the following (back-up anything important on the board first to a file on your computer - everything on the Red Pitaya will be erased):
- Take out the SD card from both Red Pitayas
- Download the 1.04-28 Red Pitaya OS image from https://redpitaya.readthedocs.io/en/lat ... d.html#id1
- Reflash the SD cards with it using the recommended Balena Etcher application
- Reinsert the SD cards and connect to the board
- Perform a factory reset to default calibration parameters - https://redpitaya.readthedocs.io/en/lat ... alibration

That should remove any software problems.

Otherwise, we do have a bug in the 1.04-28 OS where the OUTPUT:STATE ON and SOUR:TRIG:INT SCPI commands do not function (both outputs cannot be changed at once, but separately function as intended - OUTPUT1:STATE ON and OUTPUT2:STATE ON work)

Also please make sure you are using the correct GitHub branch for the examples. The "main" GitHub branch is always meant for the latest Red Pitaya OS. For 1.04-28 check branch 2022-2.
