HP 8481A PDF
Up for sale is a used HP A Power Sensor as can be seen in the pictures. This item is in working condition, however, it’s sold as-is, as described. Nothing. A remarkable HP product, the HPA sensor. It appeared on the market about , and still today, these devices are very much thought. Agilent / HP A Power Sensors 10 MHz to 18 GHz, 1 uW to mW, Refurbished HP Agilent Hewlett Packard – Used Test Equipment at Test Equipment.

A Power Sensor [Discontinued] | Keysight (formerly Agilent’s Electronic Measurement)
Will try to attach a SMD with some conductive epoxy. Maybe if the reference is blown, and you replace it by a resistor, you could still get some readings from the power meter, with very much offset baseline, and accuracy would be gone anyway, but may still be usable for some test purposes. I had experience that the gold on sapphire substrate was totally dissolved by normal Sn-Pb solder.

I found there are four screws. Maybe pure indium solder could ease this phenomenon. Still, there are many sensors around that are blown — why do so many people connect them to 0. Never tried to use indium on sapphire substrate only used if for contacting ceramics-supraconductors.
It appeared on the market aboutand still today, these devices are very much thought after. I have no idea! Notify me of new posts by email.

There is says that the sensor can withstand mW power, and even 0. Notify me of follow-up comments by email. This is all real gold on sapphire substrate! Good idea to bypass one of the thermocouples. I just purchased some pure indium and would begin experiment several np later.
Could the epoxy still have good conductivity in the several GHz and microwave frequency?
Quite some detail about this sensor can be found in the HP Journal, edition pages 19ff. Silver paste solder is an option?
Hi Rene, to measure if the elements are defect, you need to remove the sensor element from the device which is a bit tricky, because of the gold wires, etc. Note the capacity values — measures: Learn how your comment data is processed.

E-solder or other type of silver hl glue may work for some 8481s years on such substrate and geometry. Absolutely, conductive silver epoxy is also used by in industrial production, fo GHz purposes.

The conductive epoxy I can recommend is E-Solderit is not cheap, but if you keep it in the fridge not freezer it will keep well for a long time. All you need is a steady hand!
