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.

Still, there are many sensors around that are blown — 8481x do so many people connect them to 0. The conductive epoxy I can recommend is E-Solderit is up cheap, but if you keep it in the fridge not freezer it will keep well for a long time. Save my name, email, and website in this browser for the next time I comment. Maybe if the 8481w 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.
Maybe pure indium solder could ease this phenomenon. I just purchased some pure indium and would begin experiment several days later.
All you need is a steady hand! I had experience that the gold on sapphire substrate was totally dissolved by normal Sn-Pb solder.

Could the epoxy still have good conductivity in the several GHz and microwave frequency? Absolutely, conductive silver epoxy is also used by in 8841a production, fo GHz purposes.

This is all real gold on sapphire substrate! Good idea to bypass one of the thermocouples. I found there are four screws.

Silver paste solder is an option? Note the capacity values — measures: Never tried to use indium on sapphire substrate only used if for contacting ceramics-supraconductors. 8481z
E-solder or other type of silver conductive glue may work for some few years on such substrate and geometry. Quite some detail about this sensor can be found in the HP Journal, edition pages 19ff. Hi Rene, to measure if 848a elements are defect, you need to remove the sensor element from the device which is a bit tricky, because of the gold wires, etc.
I have no idea! It appeared on the market aboutand still today, these devices are very much thought after.
Will try to attach a SMD with some conductive epoxy. There is says that the sensor can withstand mW power, and even 0.
