Just suggesting you verify your signal generator before you have an unrecoverable oops. The front panel input goes into A12 Microwave Assembly, you do not want to smoke that, U1 Sampler is one part I have never located other than in another unit. The output goes to A6 IF AMP / Detector, there is an adjustment for the overload point. Perhaps obtain a manual and go thru the procedures. Better safe than @$#%!

Subject: [hp_agilent_equipment] HP 5347A frequency counter input level question

I have just acquired an HP 5347A frequency counter.
A quick run-through appears to show that the instrument is
working and displays frequencies correctly on both input 1
and input 2. Input 1 (the high-frequency input, 500 MHz to
22 GHz) has an input power level of +7 dBm Max. However, on
my unit, I get the "Overload" message if I exceed
about -10 or -11 dBm. Is this normal? I thought I could
input up to +7 dBm without overloading the input?
