Re: A homemade diode power sensor for HP meters

 

开云体育

From memory the 8484 power sensor is a diode? front end

?

But a working 8481? or 8484 go for about ?120 to ?160 in the UK equivalent to a day’s wages?

And it would take best part of a day to modify busted thermocouples for a diode by the time you did any calibration

An interesting and long running thread.

Like many, I have a bit of a soft spot for the old HP435 meters and would like to have one working on the bench.

Since broken detectors do show up now and again at a decent price, has anyone successfully reworked one with busted thermocouples and modified for a diode front end? I know it’s small and very fiddly, but is that not easier than trying to build one from scratch?
