Anritsu MT8801A/B/C & MT8802A

Sorry for digging up an old thread, but the I have quite similar issues.
I purchased today an Anritsu MT8801B which I was able to test as it powers up and opens all test apps.
However, when I started testing it to measure analogue FM-radios, I noticed it will freeze. No keyboard input will have any affect. The clock will continue to run, but that's it. No variation in measured power or whatever.
The unit is in decent shape, but all these problems are reappearing in analogue test sets, which are why I bought the unit in the first place.
Naturally, I will give the vendor a call tomorrow to see if there's anything to be done (it was the only MT880x there).

There were other symptoms too; the rf modulation measured at 100kHz (should be <5kHz) and there was no visible indication on the spectrum analyzer either.

Apparently, all these should be solved by changing the caps, but that'll be a few days work + parts.

Till now, my unit is top-notch.
I am quite amazed how powerful and reliable analyzer  is.
Analog measurement option is very precise and capable
to measure down to a few uVolts (very useful in measurements of hiss in audio preamps).
Also, RF generator is extraordinary useful in testing ham receivers (down to -143dBm)!
I am also thinking about back up the compact flash card,
unfortunately, haven't enough  software knowledge to manage that. :palm:

Are these units good for assessing RF amplifier performance, RF power, modulation  etc. on the 88-108Mhz FM bands?
What about wifi bands 2.4ghz etc?

They're fine for that, with the proviso that they won't demodulate the complex mod of the wifi

Ok I ordered a 'tested' unit off ebay for $600 with the S.A.  I hope all is well when it arrives.
thx
