[time-nuts] OCXO Soft-Start

I recognize that unusual start upcharacteristic. I will guess with a rather high confidence that thatoscillator is made by C-mac / Rakon. I have some C-Mac CFP04-A1oscillators, and they all exhibit that characteristic. These are newin the box, actually I wish there was a way to remove the pack

[time-nuts] Ocxo wrong frequency.

was messing around with one of theocxo's last night. The most easily way to guarantee an instantincorrect frequency turn on is to either start it at an under voltagecondition(ex. initial power on at 10V, with full current), or tostart it with a current limited power supply, that delivers half

Has anyone come across oscillators outputting the incorrect frequency when powered up. The frequency that is outputted reads 10.8 Mhz, and falls a few HZ as the ocxo warms up. The frequency is stable, even when measured over the course of many hours. It is a repeatable issue, when the ocxo
