Hi Mitch,
Are you trying to peak them, or do you need for them to be
at a specific value? Both of the meters you mention are really
audio meters. That they work up to 10MHz, is just the HP way.
Usually IF's are aligned by either peaking the whole mess as
seen by the AGC, or an AM detector, or using a sweeper with
a special detector. If you attach a 3400 to the IF, it will
load the IF stage so much that your alignment will be wrong.

Hi Chuck,
I wanted to measure the IF signal levels in a radio that I am trying to align. Output of one stage needs to be set to 250 mV. Again, the frequency is at 9 MHz.
