Hi They are adjustable via the RS-232 port. You type commands at them and they change frequency. Type another command and they save the setting in permanent memory.
They are still pretty close to 10 MHz (like less than 2x10^-10).

But is is still not clear to me if these are even adjustable and if not, how far have they drifted off of 10Mhz since they were new. I'd like to buy one and calibrate it to a GPS.
