SSA3032X-R AVG100 Scectra of LiteVNA64

@perfoma01,
remarkable low noise, your SH_SA44  looks much better than the SSA3075X-R.
Does its software exist for linux or is it windows only?
Here my screenshots, 100 MHz signal originates from SDG6052X.

Well, the SA44 has a very different mixing scheme, so it is hard to beat at lower frequencies and narrow spans. In general, it has quite some limitations, but whith the right settings it can outperform most of the "big boys" in certain situations.

There is at least a Spike version for 64-bit Ubuntu.

My signal source has been a SDG6052X as well. For the following screenshots this wasn't even necessary, as the SA44 happens to produce a strong spur at exactly 100 MHz :-DD

The attached screenshots show the noise floor around 100 MHz with and without preamplifier.

Sorry not catch you - could you please provide a more detailed procedure.

Thanks in advance.

I think you could switch between FFT and accuracy under sweep settings.

What do you hope for when the measurement is made with an R&S Analyzer?
I could offer a measurement with an SA4401A VNA and an FSIQ  or SMIQ + FSIQ.

tautech:
Just because I had one out and not yet had access to an X-R, a quick check with my SNA5004A in SA mode.

KeBeNe:
What I saw in the pictures of @kladit that the correction is off, is that the default setting on the R model?
