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.

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.

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.

Because I am being me???  Thank you!  Cleaned up my work area so I can see what I am doing and set trigger to DC.  Sweep now takes a deep breath.
