Re: HP8640B output 10db low on all settings
I have figured out what is going on. The output attenuator vernier knob, when reduced towards minimum, cause the 0-3 level to light, and the 1-10 light to go off, this drops the output by 10db even

Re: HP8640B output 10db low on all settings
If the 10 db pad were stuck, the output would read +10, +10, -10, -10, -30 etc rather than +20, +10, 0, -10, etc What's the -140 db position? My unit and photos on the web I see only have +20 to -130
