I have a Bulova crystal oscillator, part number 1505869-1K, model number
AMO31HP-V-1, NSN 6N5840-797-7659.
The NSN tells me it is a little old and that it was a turn-in, probably
repairable at some higher level.
The frequency is marked 100.000000 KHz.
The oscillator voltage is 30 V DC and the oven voltage is 115 VAC.
It has an octal plug on the bottom with the pins marked:
1 - oven indicator
2 - A.F.C.
3 - heater power
4 - +30 VDC
5 - case ground
6 - ground
7 - heater return
8 - 100 KC output.
With the nameplate listing the frequency in KHz and the case listing the
frequency in Kc and the older NSN, it appears that this oscillator was
made for a longer period of time.
The top has two adjustments, both with a screw cover.
One is freq adj and the other is output adj.
Does anyone have any data on this oscillator?
What would I expect the accuracy to be?
The printed frequency implies, to me, that the accuracy is in the realm
of 0.001 Hertz at 100 KHz.
Did I miss something here?
The top also shows this to be a "Generator Reference Signal".
Any insite appreciated.
