[Boatanchors] Heath IG-42 - More

[Garey Barrell]

Yes, the IG-42, with the meter set to "10" and the Step Attenuator set 
to "x10,000" if calibrated correctly, put 100,000 uV RMS into a 50 ohm 
load.  That is 0.1V RMS or 0.2828V p-p, which should be enough to drive 
any counter worth the name up to 30 MHz.

Unfortunately, it does not have an "uncalibrated" output to drive an 
external counter.  Certainly one could be added.  Heath really did a 
nice job cooping the RF up inside the cabinet, fully shielding all 
circuitry inside the outer cabinet and including a power line filter to 
keep RF off the line cord as well.  It's about as good a job as you 
could ask for a generator in it's price range.

Plus, it's a LOT easier to move around than my HP-606A!!
