>Bruce Thanks Bruce, I used a HP5335A counter to measure the ref out at 10.000,000,3MHz and the 200MHz test point-1 on the multiplier board as 200.000,007 MHz The HP5335 is not calibrated but it looks like the multiplier is working O.K. I have no way to measure the harmonics as I do not have a RF spectrum analyser. The test point has a nice 200MHz sine wave as tested with my eye and a 150MHz CRO. I also adjusted the DAC voltages on A18 although they were close enough. BTW I think the "set test switch" settings for the DAC module A18 may have a error. I think the OA cal switch settings should be the same as the OO cal settings. Could the harmonics from the multiplier be causing the problem?
