Huge Changes in PUCCH and PUSCH SNR Values

[FawalWasiela]

I am trying to dump the values of the PUCCH and PUSCH SNR values to a file which I will later do some analysis on these them. I simply added a logger function to the code to export those values to a .csv files when that part of the code is hit. I dump the variable "pucch_res.snr_db" that is in the file "/src/srsenb/src/phy/lte/cc_worker.cc". after dumping the variables I see a huge dynamic range of the SNR and a sudden changes that are problematic, like the SNR changes from 20 to -0.5 dB in a couple of microseconds. My question is:

1. Is my attempt to dump the values using the method I mentioned even valid?

2. If it is valid, What is the reason for those huge changes?

3. If it is not valid, how could I get those readings for the PUCCH and PUSCH SNR?

Please note that this huge dynamic range was also present when I tried to use the virtual radio ZMQ to make sure that there's not any thing wrong with my setup. please find a sample of the dumped values attached below
