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
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 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.
