Thanks to everyone for their replies, and to Bob Raker for a scan from the 1990 Vectron catalog.
The unit is spec'd to run from 24V, +/-5%, with 12-28 V tolerable at varied output power.. The CO-22 indicates a higher output level and frequency. A standard unit should deliver +13 dBm into 50 Ohms at +24 V. An L2 unit should deliver greater than +10 dBm into 50 ohms at 24 V. This particular unit does not have the external voltage tune option. Stability is spec'd at +/- 3 e10 ^ -8 over +15C to +35C (Temp Range A). The "3" indicates an aging of 3 e10 ^ -8 / day, 5 e10 ^ -6 / yr. The L2 suffix indicates an ultra low phase noise option, which is 10 dB better than the standard option. Specs for standard and L2 options: Offset Standard L2 kHz dBc/Hz dBc/Hz 0.1 -120 -130 1 -135 -145 10 -140 -150 50 -145 -155 The unit has never had wires soldered to it. The output power measures +12 dBm at 100 MHz on my 8560 spectrum analyzer. (An indicative but non-authoritative power measurement) Dropping the input voltage to 15 V drops the output power to +10.5 dBm. The startup current at 24 V was about 240 mA, dropping to about 118 mA after warm-up. I will have to look up the specs on the company Agilent E5500 phase noise test set; it is quite possible that this oscillator is spec'ed beneath its noise floor. Regards, John John P.
