Hello all, I would like your opinion on one matter that happened in my lab not long ago.
I found out that my RF generator was sending a much lower power than it was specified. If on the display it was described as it was generating 0dBm, the real output power was around -50dBm. I also found out that, one of my co-workers, previous to this problem, had connected the RF output (with 50hm of impedance) to an oscilloscope (with 1Mohm of impedance). Of course, this means that I had a full signal reflection on this case. The signal was around -20dBm in 35kHz. Should I assume that my generator is damaged? Or maybe I have another kind of problem, and this connection and reflected wave do not pose a threat to the generator? Thank you very much for your help.
