Subject: [HP-Agilent-Keysight-equipment] Replacement OCXO board for 5315B

Hello everyone,

Just as a follow-up for the other topic (1820-2131 for the 5315B counter).

My 5315B came with Option 004, which is the high-stability OCXO. Unfortunately, the Ovenaire 85-50 oscillator had a problem with the heater which stayed cold, so it "worked" and generated a sinewave, but was 30 Hz away from its nominal 10.0000 MHz.

I decided to use another OCXO and got a Bliley NVG47A, for which I designed a PC board which mounts on the original bracket intended for the Ovenaire oscillator (re: attached pictures). No electrical or mechanical changes to the counter are needed.

I have a few bare PC boards which I'd be glad to sell for $1 each plus the price of mailing from France. If anybody is interested, please let me know !

Cheers,

Joel
