[time-nuts] HP 5090B

[Robert Atkinson]

Hi David,
I had one of these years ago. As others have said, its a UK 200kHz receiver. full of pot core transformers. I decided it was not worth the effort to convert it to 198kHz. In the end I put a OCXO and divider in the case.

OK, I just got one of these as part of a lot of other test gear.

What is it for?  I found nothing searching the archive, and Google didn't help much either.  The Agilent site disclaimed all knowledge!

I suspect it MIGHT be an off air frequency standard as it has 1MHz and 100kHz outputs and an aerial input.

Any clues - or pointers to documentation?

Regards,
David Partridge
