Hello!
I am making Conducted Coupling tests on an RS485 communication circuit by applying 10 V over a frequency sweep of 1 to 230 MHz. After some time of running the tests, I see that the communication fails, and I cannot get it to work at all, even without the added disturbances. After a couple of hours of waiting, I can communicate with the circuit again. Can it be due to overheating of the transceivers, and that they self-heal, i.e. cool down, after a couple of hours, or what is the phenomena behind this?
If this is the case, how can I protect my transceivers from this phenomena?
