Need manual for old Boonton generator
 

I've searched everywhere on the web with no success. I need a manual for a
Boonton 103F signal generator. If you have one or know of a likely source,
please contact me. Thanks.

Hi Floyd,
Exactly what do you need from the manual? I have a manual
for the 103D, which is the 125kHz to 174MHz model. It is a couple hundred
pages, with fold-out schematics, so it would be quite expensive and time
consuming to copy. If you just need a couple of pages, I can help you.
As an alternative, you can contact Boonton. This is their URL:

One thing I want to mention about that generator............there are 10uF
caps in parallel with the large filter caps on the power supply board. When
these caps dry out, the -5.2V regulator for the ECL circuitry oscillates.
This will cause numerous sidebands to appear on the RF output, along with a
dancing display that never seems to indicate a locked frequency.

Thanks, Pete. I'll take a look for those caps. I know that the 103F supply
is different from the 103D because of a previous problem, but the caps could
be there. I've got the major problem fixed. There was a fuse hidden inside
the RF output connector and it was open. My 103D manual shows a fuse as an
option, but I assumed it would be somewhere in sight if it was installed.

Pete - I wonder what you find that 1MHz input useful for? Does that allow
you to lock the oscillator in phase with the external oscillator ? If so,
how do you use that capability?

By the way, I located the four 10 mF caps you mentioned in the power supply
and will replace them today before I button up the unit again. While this
103F is very much the same as the 103D, there are some unusual differences.
The frequency ranges are different and the upper limit is 100 MHz instead of
175 or so. Also, there's no sweep capability. The metal tag on the unit
indicates serial number 1, and has a contract number scratched in, so I
wonder if this wasn't a one-off that was never produced in quantity.

Hi Floyd,
I am glad that you fixed the unit. I burned out the fuse
in
my unit, and went through the same process of trying to find it. It is my
favorite generator. I like the fact that it has a separate 1MHz OCXO for
phase locking the unit.

That external 1MHz input is useful if you want to lock the generator to a
Cesium or Rubidium standard. As an example, if you are doing frequency hop
tests with a synthesizer, you can use the same reference for both the
generator and the synthesizer. This way, it makes it easy to measure
settling time. On another note....................I don't have too many
spare parts for these units, but if one of your ECL 10K devices ever dies, I
do have some of them on hand. I haven't run into a dead one yet, and I hope
that the 10116 device never dies (the one with the heat sink mounted to it),
because I don't have any of those.
