Boonton 102F Signal Generator Query - UK Vintage Radio Repair and Restoration Discussion Forum

Deltatango · 14th Jul 2021, 10:43 pm

Just to get some information on a part please:-

There is connector between and through two aluminium housings with a link through it, in its manual this is listed as an AMP product 60789-2 (J1701 location), this connector is made through a threaded tube to screen it, with solder points at each end and both look to be mounted on ceramic insulators. One end is a hex screw on cap its other secured with a nut on that threaded tube

Its design looks a bit like a feedthrough type device with maybe 100pf and carries clock pulses to another board.

Just need confirmation of what it is, because the pin and socket inside has a poor connection, if I could confirm its identity that may help me decide on a cure for it.

Thanks for any help David

I don't know that one, but HP and Boonton had a close relationship for many years. It may be something I've seen in HP stuff.

Photos would help.

It's a nice-looking synthesised sig gen with early 1980s sort of styling.

What signal is the connector carrying? Clock pulses doesn't tie things down much.

I think it may be a homebrew item but can now include some pictures to give an idea of it, seems to have capacitance at each end to ensure the clock pulse is clean to pass on to its next module.

Hope it helps to identify the part.

Many thanks from David

Pics 2, 3 & 4 look like they were took from outer space : ) Isn't it just some sort of connector similar to an SMA? Could it be the capacitance your seeing is part of the fault? The one pictured below looks similar, bigger than an SMA, smaller than BNC. But basically a metal threaded tube with straight wire insert in a low dialetric plastic.

Could connecting the modules with a straight wire or a 100p cap as a test should give some idea of the craic?

It was made by Boonton Electronics, not the Boonton Radio Corp. that HP acquired.
Boonton Electronics (now called Boonton) formed in 1947 and are now part of the Wireless Telecom Group, Inc. https://www.boonton.com/about/corporate-profile

Booton Radio Corp date back to 1934; http://hparchive.com/boonton
I have a transistor tester from another Boonton based instrumentation company, Measurements Corp, there are a few others in this old article; http://hparchive.com/wp-content/uplo...ey-Article.pdf
