HI All , first time request. I wish to know how I can accurately set some oscillators on frequency. I have 3 Sulzer oscillators .. 1 x 2.5A and 2 x 2.5C's and 1 matching P/S with dead nicads. My main reference is a Trimble Thunderbird which was the second source to the HP unit was used in cellular phone installations in the US a while ago I think that they maybe Nortel pulls like the HP's that were around. I have tried in the past by putting the main reference into input "A" and triggering 1 cycle of 10 MHZ and feeding one of the other oscillators into input "B" and adjusting the Sulzer to be totally overlaid with no movement over many hours.. All Sulzers had been on for 36 hours before the test.and the Trimble has been on for 2 years. What accuracy can I expect from this method, and is there a better method with the equipment I have. Regards, Don VK3YV.......
