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.

There is says that the sensor can withstand mW power, and even 0. Maybe pure indium solder could ease this phenomenon. The conductive epoxy I can recommend is E-Solderit is not cheap, but if you keep it in the fridge not freezer it will 8481z well for a long time.

All you need is a steady hand! It appeared on the market aboutand still today, these devices are very much thought after. E-solder or yp type of silver conductive glue may work for some few years on such substrate and geometry. This is all real gold on sapphire substrate! SimonsDialogs — A wild collection of random thoughts, observations and learnings. 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.
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. Quite some detail about this sensor can be found in the HP Journal, edition pages 19ff. 848a the epoxy still have good conductivity in the several GHz and microwave frequency? Good idea to bypass one of the thermocouples.
I have no idea! Note the capacity values — measures: Absolutely, conductive silver epoxy is also used by in industrial production, fo GHz purposes. Notify me of follow-up comments by email.

I had experience that the gold on sapphire substrate was totally dissolved by normal Sn-Pb solder.

Never tried to use indium on sapphire substrate only used if for contacting ceramics-supraconductors. Still, there are many sensors around that are blown — why do so many people connect them to 0. Learn how your comment data is processed. I just purchased some pure indium and would begin experiment several days later.
I found there are four screws. Will try to attach a SMD with some conductive epoxy.
