OCXO Upgrade for KS 33521B - Looking for info

[HighVoltage]

Congratulations on your modification
Yes, this is a very quick and low cost upgrade.

Actually I am surprised that this is not a standard for all the counters from Agilent / Keysight
The models without the OCXO just suck in stability.

If anyone has high resolution photos of the front panel PCB for the 33521B, I would be very grateful. The trace from the CMOS battery is damaged on my 33509b front panel and I am fairly certain an inline resistor fell off my pcb. The front panel should be the same as on my 33509b

Thanks!

KS 336xx Models & OXCO: Does one exchanged any OXCO on this models too? As similar models IMHO...
