Re: HP Power Sensor wanted

I have an HP33330B 18 GHz Low-Barrier Schottky detector that I
use with a set of Radiall attenuators. I calibrate it now and
then against my 8481A and 8481D heads on an HP436A. I'm thinking
of building an interface to it with an A/D converter and PIC and
building that into a 435 case with a rechargeable battery and a
USB interface for charging, updating the calibration curves and
reading the output using a 436A or ACPI emulation.
OK, I could build it into a small case with an e-ink display, but I like the big analogue meter when tweaking things. I have a 435B that is very clean and works well, so I'd have to find an unloved one to gut and re-purpose. Having it run on batteries would make it a lot more useful.
