I am experiencing strange behavior of the spectrum analyzer overlay implemented with the RFSoC2x2 module. Regardless of whether the inputs are connected or not, I observe a signal about 100 MHz wide on the spectrum. I am using a standard, freshly installed image version 2.7.
Additionally, when I turn on the spectrum analyzer, the program stops working. The spectrogram cannot be turned on. The signal spectrum is static, it does not refreshing.
For comparison, I have no such problems on the ZCU111 module.
Are there any additional tools to verify correct operation of the module?
I have opened a GitHub issue for you on the rfsoc_sam repository here:
I’ll investigate your issue shortly. Meanwhile, you can subscribe to the issue for updates,
