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.

Quite some detail about this sensor can be found in the HP Journal, edition pages 19ff. I had experience that the gold on sapphire substrate was totally dissolved by normal Sn-Pb solder. The conductive epoxy I can recommend h; E-Solderit is not cheap, but if you keep it in the fridge not freezer it will keep well for a long time.

It appeared on the market aboutand still today, these 84881a are very much thought after. I just purchased some pure indium and would begin experiment several days later.

Will try to attach a SMD with some conductive epoxy. 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. Note the capacity values — measures: All you need is ph steady hand!


Maybe pure indium solder could ease this phenomenon. I have no idea!

I found there are four screws. Could the epoxy still have good conductivity in the several GHz and microwave frequency?

E-solder or other type of silver conductive glue may work for some few years on such substrate and geometry. There is says that the sensor can withstand mW power, and even 0. Notify me of new posts by email. Save my name, email, and website in this browser for the next time I comment.

hl Silver paste solder is an option? Still, there are many sensors around that are blown — why do so many people connect them to 0.
