Hello,
I have two spectrum analyzers that are giving me very different results.
Using the first analyzer, I used the 'channel power' measurement function on a local FM station. The result is about 39.5 dBuV.
I then unplug the first analyzer and plug in the second one at the antenna feed. Using all the same settings, the new result is 30.97 dBuV.
I'm not trying to do certification testing or anything, so accuracy isn't crucial, but a 10 dBuV difference is a lot.
The two analyers are the Anritsu MS2720T and the Keysight N9343C. They advertise .5 dB and 1.3 dB accuracy, respectively.
Are the channel power measurements (39.5 dBuV and 30.97 dBuV) inside the range of variability that you would expect, or am I doing something wrong?
Thanks,
Pete
