The 8508 is very nice for watching the phase diff of 2 signals say 10 MC. Note the phase, wait some time and see what the new phase is. Thats the drift rate and offset for the oscillator in question. I have a older version of this system. I have never had any gpib software or anything like that. Heck I do not remember if it even has GPIB. Never needed it. Regards Paul WB8TSL
