The 8484 is a dione power sensor. Many other HP diode sensors end with t "D" instead of an "A" in the model number.
E.g. 8485D as opposed to 8485A

Quoting Paul Bicknell <admin@...>:
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

Subject: Re: [HP-Agilent-Keysight-equipment] A homemade diode power sensor for HP meters
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?
