SSA3032X-R AVG100 Scectra of LiteVNA64

<< < (4/8) > >>

tautech:
Does result = same after Default Preset and set up the SA again ?

markus_jlrb:
@tautech,
and all,

I have preset the SA as requested.

Compare the screenshot of SA mode vers RTA mode.

What do you think?

See the small blue line in between the noise in RTA mode.
this is the AVG100 line - no irregularity there.
This is a proof that FW has an issue in simple SA mode.

Am I right?

Thanks to all for your effort.

I have reported this findings to Siglent Germany pointing
to this EEVBlog thread.

kladit:
Now the difference is not so big as before.
Use markers to make the results numerical comparable.
What do you use for the external 13 dB attenuation?
Here two mini-circuits bnc attenuators 10 dB + 3 dB in series.

markus_jlrb:
See my measurement constellation.
SDG6022X in 50Ohm mode and 0dBm output level.
