Here is some info about those things. Very easy to make when it's under 1GHz. I made several using geramnium, schottkey and kristaldiodes. For small signals with lowlevel the shunt type is the best option I think.

Hi Dave I have a 2000 under the bench somewhere it has a problem I havent
sorted yet, I was hooked on those "compactrons" :-)) It is probably propping
up the bench !!
I think any "diode probe" circuit would do, even using a silicon 1N4148 or
1N914. these were not precision equipments and were used only at faily high
levels. The return to the mainframe is generally for the mixing in of
markers, and is not essential if you dont want the markers. I have collected
a number of Marconi, GR and, and HP diode detectors most would be overkill
as they are rated to 10GHz or higher.

Hi John,
Actually, I have 4 analysers... The issue is that this sweeper is designed
so that signal goes out to the DUT, through the detector and back into the
sweeper before returning out again as H and V signals for a scope or
plotter. The detector expected is a simple BNC in/out type.

I'm assuming that you don't have access to a spectrum anlyser.....
How about just plugging up to an oscilliscope with a 50 ohm thro-termination
(or equivalent) ?? 0dBm = 0.632v p-p

Ok, so I have Telonic SM-2000 sweeper from about '64, which appears to be
working correctly, but in order to ~calibrate it (or even completely verify
operation) and need an appropriate rf detector.?? The user manual is no help,
"see our literature for recommended detectors", ...right...?? The only plugin
modual I have spans 0-20Mhz, so we're not talking high speeds here.?? There's
got to be a simple schottky based circuit that would work here.??
Any ideas???
Thanks!?? -Dave
