Subject: Re: [HP-Agilent-Keysight-equipment] HP 11664A Detector - DIY equivalent?? I have done as Jeff described a number of times to get someone a working scaler analyser I use the 11664 C detector adapter for frequencies above 18 Ghz? so if you are making an adapter without using an old 11664 then the circuit used in the D version is actually better and easier to configure to different detectors ? Also I have seen possibly on this site a modern board lay out using modern components Paul B ? From: [email protected] [mailto:[email protected]] On Behalf Of Jeff Kruth via groups.io

Subject: Re: [HP-Agilent-Keysight-equipment] 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
