almost all of the 848x series power sensor heads use a thermocouple and

directly from HP/Agilent. They were crazy expensive (like $750) as I
remember) plus you needed an eye loop and the nerves of a? Swiss
watchmaker to replace them. What is essentially being attempted here is
to make a diode version of the power sensor head as a replacement since
the heads have become scarce and expensive in their own right.
"parkertest" on ebay seem to have bought a lot of replacement thermocouples and are selling them at $7200 obo for 20!
They will also repair an 8481A for $465 or sell a refurbished one for $475 obo.? Kind of puts a limit on the value of these things.
