Hi, I have a 7L12 and a 7L14 and I made my self the same question. With two prescalers and two counters is possible to make a circuit and write in the readout system. Anyway I?m searching for a TR502 system with counter.
Regards
Miguel

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.
Regards
Gudjon
