Thanks for the answer Chris
You made things a bit clearer.
I don't need accuracy, just stability. I do have a frequency source
that I can use to tune into the frequency I'm after
but then I would like to keep this stable.
In zero span mode I should be able to use a frequency counter on the
1st LO. I found one for frequencies up to
5.8GHz for a reasonable price.
In scanning mode I will try to read the DVM input voltage (U2140) with
a more precise external
DVM and see if I can use it for some improvement.
I will test and let you know if it works.
