EMC Testing - Changing Radio Frequency with SWD?

[William Geng]

Hello All.

We are planning to do a EMC test on our device that is using nRF52832, the test facility requires us to provide a programming interface that can change the frequency of the radio to test across the full range, does the SWD interface of the nRF52832 support changing the radio frequency register on the fly?

Cheers,

William

Any reason why you don't just use the DTM (direct test mode) example?

Yes, SWD can change the RADIO, but good luck writing those JLINK scripts.

Thanks! I wasn't aware of the DTM, so does that mean for that I will just need any two GPIO configured as UART and run the DTM example on it?
