[time-nuts] HP5334A Opt 010

[Flemming Larsen]

Hello Javier,

>From the HP5334A Manual Parts List:

  05334-60001 (Standard) and 05334-6006
  (Option 10) A1 Main Board Assemblies are
  identical except for C8, C100 and Y1.

The Field Installation Procedure for Option 010
includes the following:

  Remove A1C8 and install A1C100 using the soldering
  iron.

Nothing is mentioned about A1Y1 in this section, so
it may be OK to leave this in place.

Looking through the parts list, I notice that C8 and
C100 (.01 uF +- 20% 50VDC CER) have the same part
number, 0160-4554, so all that should be necessary
is to move C8 to the C100 position on the main board.

If you don't have the Option 010 Oven Oscillator
Support Board, you could also "borrow" the needed
supply voltages from the 6-pin connector on the main
board, feed them through the rear panel, then make
your own interface board, and mount this board and
the HP10811 oscillator in a separate enclosure. You
could then feed the 10 MHz signal from the HP10811
back through the Time Base In/Out connector on the
rear panel.

In this case you would not need to make any
modifications to the main board.

You could also make your own power supply for the
external oscillator to have a complete, stand-alone
10 MHZ source, which you could use for other
applications.

Sorry to bother the list, but this is NOT off-topic,
and may be of interest to other members on the list.

Regards,
