In the Measure menu I dont find it. There is "Channel Power", "ACPR" and so on.
In the Sweep menu I find "Points" = 751 at the bottom, but its grey, I can not modify. (Picture) Manual tells a max of 751 but not how it can be modified.

I dont find it in the SA mode to select it.

The pictures "SigSpek" and "SigScope" show the Siglent Generator at -10 dBm (10 dB Attenuator in the connection cable). Measured with the Rigol SA and with the Scope. Looks clean.
The pictures "RigSpek1 and RigSpek2" and "RigScope" show the Rigol Generator at -20 dBm. Measured with the Siglent SA and the Scope. Looks short time clean but if I select MaxHold shows that the signal jumps, also visible in the Scope picture. Looks a bit strange but may be no issue when used for the VNA function.
Both where configured with Zero Span.
I will add VNA and Realtime function next days and then I have to choose one and send back the other.
If somebody has a suggestion what else I should look on just let me know.

So RigSpek2 shows the Rigol with tracking generator set to 100 MHz at zero span. Wonder where all that spurious is coming from! The waveform is severely distorted. The Siglent waveform looks perfect.

This is RigSpek2 but mislabeled as it's from the Siglent analyzer and certainly not zero span.
I see some broadcast and possibly LoRa signals.

Sure the picture is from the Siglent as I measured with the Siglent the Rigol TG. The Rigol was set to zero span to be at a fixed frequency. The Siglent which measured the Rigol was set to 1 GHz span to measure also the harmonics. So "RigSpek" means the Spektrum of the Rigol TG measured on the Siglent.

So there seems to be a problem with the Rigol's tracking generator on zero span. It looks like it's still sweeping. Did you try it on zero span on any other frequencies?
