Hi. I'm not sure if there is a problem with the tracking generator of my Rigol DSA815. When I watch the signal with the scope it looks like the graph is not sinusoidal for <1 MHz.
I recorded a sweep from 500 kHz to 1.5 MHz, sweep time is 10 seconds:
On the spectrum analyzer the graph shows -18.1 dBm at 500 kHz and -19.2 dBm at 1.5 MHz. I don't think that the cable (RG-58) is that bad:
The setup is a cable from the tracking generator to the scope and back to the input of the spectrum analyzer:
Can anybody reproduce that issue? Is there a problem with my tracking generator or does every DSA815 act like this?
