[Test-Equipment] Jerrold RF Detector

[Raymond LaRue]

If I recall correctly, (I used several of these many years ago (mid-sixties), for bench sweeping CATV and MATV amplifiers and filters, etc.).  

They were used with a broadband sweep generator to enter markers from an external marker generator and then drive a scope with the detected RF.  The combo produced an X-Y display on the scope showing a device's bandpass characteristics and with frequency marker pips inserted.   

They were typically set up for 75 ohms with "F" connectors.  Yours may be for 50 ohms.  Jerrold did have some sweep gens for 50 ohm applications.

Greetings All,

        While I was looking for parts this morning to finish up a long over due project I can across the little devise. It marked " RF Detector, Model D-86, Freq 0.5 - 250 Mcs ", made by Jerrold. It's a roughly square box, about one inch thick. It has four BNC connectors marked as follows, RF Input, RF Output, Marker, Scope. I would guess it was used in the Cable TV Service. Dose anyone have information on it. All my web searches came up empty. Thanks
