[time-nuts] Vectron OCXO 204-8888

[Heinz Breuer]

Hello,

it seems that I have an similar (?) unit here. It says:
ELECTRONIC RESEARCH CO
EROS-800-A1
AMD135-30698
5.000000 MHz
S/N 23   Date Code 90-10

Same dimensions but other pinout: 
It has two coax cables attached

Pin 1 NC
Pins 2, 3 and 7 are GND
Pin 4 Coax cable center, no connection
Pin 5 Coax cable center connector with 8.3 kOhms to GND

There is a SMA connector which probably is 5 MHz output

Unfortunately I don't have any data on it. 

I would appreciate any data about it.

Best regards
Heinz Breuer DH2FA, KM5VT
