Is my Siglent 1032 Defective???
watchmaker:
I wasted today trying to align an FM radio. But my sweeps made no sense.
Finally, I decided to check the output of the Siglent against my TinySA.
Below are pics of the setup and the screenshots of when I trigger off the Siglent and then the TinySA. I also took pics of the TinySA setting and the Siglent setting. The Setup shows before I set both to 20ms sweep time.
The trace of the TIny SA breathes as expected. The trace produced by the Siglent is hash with no evidence of "breathing".
Before I call Siglent, I would like to ensuure It is not me being me. Output 1 and Output 2 produce the same result. While I was trying to use 10.7MHz, you can see these sweeps are set for 100KHz.
I corrected the setup picture.
THANKS!!

Use a Burst setting also for the sweep.

Thanks Tautech. I will do this in the AM; after I clean up the barf. I was elbow deep in leads and stuff by the time I wrote my plea. Called it a night.

I think I understand why you wanted me to test Burst Mode. The trace of N cycles jumps right to left. The trace is clear at 10KHz and 10MHz, but it will not lock. I can tell myself this is very similar to what I see in the Sweep function.

tautech:
I believe you have some settings incorrect......I look at your screenshots and everything is AC coupled, why ?
I haven't got a SDG1032X to test so used my SDG6022X that has the same functionality albeit to much higher frequencies.
Sweep 10-100 kHz over a set duration.
