I recently acquired an FE 5650A 10 MHz standard. So far, I cannot get the status indictor to lock.
This 5650A has option "CFOM" whatever that means. It appears the 5650A came in several configurations. I do not see that option listed in the FE manual. My other 56050A has option 20 and lets me use a single +15V supply. It's possible that lock isn't occurring because it may need a +5V supply like 5650A models that do NOT have option 20. I am using a +15V Dell laptop supply that works great with the working 56050A. A status LED and 2N3906 transistor was added into the DB-9 power connector to indicate when lock is achieved. Never a problem with the working 5650A. Can anyone provide any information with respect to option "CFOM?"
