Re: HP 11664A Detector - DIY equivalent?

Yes, I have. Polarity of detector doesnt matter, as the signal is chopped at 27.8 KHz.
Best bet is get a blown detector then remove the detector bulkhead and fashion a small aluminum sheet metal plate to hold a BNC, replacing the bulkhead with this. It is the same as an HP11664C detector adapter. Easy-peasy. Works great.

Hi,
I've been looking for a couple of HP 11664 detectors for a network analyser but was put off by the sky high price - even for second hand items of dubious condition.
I've seen a web page showing a DIY equivalent using a?33330B?(positive)?detector and an amplifier replicated from the HP service manual.I was wondering if this is a sensible/realistic thing to attempt? Has anybody ever tried this?
thanks
Tony
