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.

I just purchased some pure indium and would begin experiment several days later. Notify me of follow-up comments by email. I had experience that 84811a gold on sapphire substrate was totally dissolved by normal Sn-Pb solder. This is all real gold on sapphire substrate!

Still, there are many sensors around that are blown — why do so many people 8481z them to 0. 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.

Will try to attach a SMD with some conductive epoxy. All you need is a steady hand! E-solder or other type of silver conductive glue may work for some few years on such substrate and geometry.

Good idea to bypass one of the thermocouples. It appeared on the market aboutand still today, these devices are very much thought after. This site uses Akismet to reduce spam. H; — A wild collection of random thoughts, observations and learnings. The conductive epoxy I can recommend is E-Solderit is not cheap, but if you keep it in the fridge not 848a it will keep well for a long time.
There is says that the sensor can withstand mW power, and even 0.

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. Learn how your comment data is processed.

I have no idea! Note the capacity values — measures: Could the epoxy still have good h in the several GHz and microwave frequency? Your email address will not be published. Maybe pure indium solder could ease this phenomenon. Never tried to use indium on sapphire substrate only used if for contacting ceramics-supraconductors.
Silver paste solder is an option? I found there are four screws.
Absolutely, conductive silver epoxy is also used by in industrial production, fo GHz purposes. Notify me of new posts by email.
