Hello, all!
I am using demo file benchmark_tx.py and benchmark_rx.py to test the average PER at a certain distance. Whenever I initiated a test, the first two or three PER varied violently. For example, the expected PER is around 4%, in the first three tests, PER might be 30% and after the first three tests, each PER in each test would change within a constant range, say 4%. Does USRP need some warm up before it goes to its stable state?
Thanks a lot for all!!!
Bill
