Re: HP 11664A Detector - DIY equivalent?
¿ªÔÆÌåÓýHi? ok? I made a mistake as quoted? the D when I should have quoted C ? The 11664A is up to 18 Ghz? the? 11664C is the detector adapter this allows you to use any diode detector with the scaler analyser and I have personally used this up to 75 ghz The 11664D is 26 to 40 Ghz? with? wave guide input? and I do not have any documentation on this part ? So basically we now have ( as I have just uploaded them? ) the operator and service manuals including? the CCT for the 11664 A and the C? on this site and that is all that is available at this time ?

Hi look in the ?photos on this site and you will have the 11664D admittedly not that good but also a new design based on modern components Paul B ? From: [email protected] [mailto:[email protected]] On Behalf Of Dave Brown ? 11664D schematic somewhere? The manual in? files section of grps io is ops only, no ccts. DaveB, NZ ? From: [email protected] [mailto:[email protected]] On Behalf Of Paul Bicknell ? 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 ? 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. Jeff Kruth ?
