Use Siglent SSA as LCR Meter / Bode Plot?
techneut:
This what my screen showed the first time after upgrading:
https://www.eevblog.com/forum/testgear/siglent-ssa3000x-spectrum-analyzers/msg3087608/#msg3087608
It looks a bit familiar.
tautech:
So after a rat around found some Cal standards and went through a 1 Port Cal and applied it.
The load used is a quite good one and later compared against a homemade 3x 150 Ohm SMD resistors in parallel.
Screenshots attached for reference.
Attenbach:
thank you so much techneut, that was exactly the issues. I have added my finding in the the SSA3021X thread and will use this thread to continue explaining how to use this device to do component analysis. Thanks!
Attenbach:
Ok, I am back in business. I managed to measure the first passives here as shown with this inductor coming in at around a sensible 250 µH.
Does anyone know whether it is possible to plot a single variable vs. frequency, for example here plot inductance (Y) vs frequency (log10(x))?
Feels like a low-hanging fruit to have such a plot with so much more to offer. Especially given that Siglent doesn't offer a dedicated LCR Meter or IA.
I have tried all formats, but none reveal more info than the R+jX and rotating the cursor to get a feeling.
Thank you
PS: I suspect if there is no such thing, the last solution is to export the raw data through SCPI into the pc and plot it there... :--

@Attenbach,
that's the point that I meant, see attachment.
You are working with power-coils/power-transformers,
so be careful not to catch some energy spikes while measuring
with your SSA (like from solder iron, motor, psu, other em-fields from transformers, etc.)
in order not to destroy your new device!
Same refers to caps in nF/uF range holding charge not being
discharged properly!
