Hi All; Does anyone have a data sheet or experience with the Symmetricom 1111C, I have one in a Symmetricom 4065C and the internal diagnostics say it is at the end of it's tuning range. Is there a way to do a coarse manual adjustment, or is it a possibility the Cesium is locking to a side peak? In addition the +- 15 volt supplies have failed to switch on twice during testing, but have switch on after rebooting. On one reboot it locked quickly. Thanks; Thomas Knox
