Hi EE-digger,


--- Quote from: EE-digger on May 12, 2024, 02:04:08 am ---For a handful of minutes I was in fear of not being able to display a stored trace and a live on top of it.  Siglent does not make this easy.  But their trace COPY, MOVE and other stuff seems pretty complete.  I was able to get a live and stored overlayed but need to do it a few more times.  I think this would make a good YouTube video as it's commonly used.  Maybe when I get some free time.  update - displaying live and stored trace is a piece of cake which I missed.  It's under MATH.

Could you please detail how you got this working?
I'm still looking for this after several minutes :)

Ok, I think I've found it. The "Data->Memory" button copies the trace to the memory of this one trace.
Then, "Display" let you choose if you want to display the trace or trace+memory or the memory alone.

EE-digger:
Glad you found it.  There are other things which could use written help somewhere.

Averaging is another.  In VNA, you enable averaging under the IFBW button.  In SA, like many SAs, you change the trace type (under math, trace type) to averaging.  Averaging then appears on the soft keys.

I'm also in search mode, see next post.

EE-digger:
The SNA5000A does not have a ZERO SPAN mode for the SA.  This is a real problem because without it, you can't examine any time domain characteristics of a single frequency signal (for instance, advertising on Bluetooth).

I hope Siglent will add this at some point.  I hope they can.

EE-digger:
In VNA mode, does anyone know if there's a way to use a delta marker between a memory trace and the current data?  The memory trace does have it's own markers, using the same marker numbers but in their own little world.
