Hello,
This is a question about the DAC37J84 v1.1 GUI, screen DAC3XjX Controls, Dig Block 1, ABQMC EN.
DAC channel A and B are outputting 100 MHz sine waves, 60 deg apart at sample rate = 983.04 MHz. I set Phase AB = 0, Gain A = 512, Gain B = 512. When I click AB QMC EN the sine waves phase jumps about 100 degrees. When I click QB QMC EN off the phase goes back to normal. This does not seem correct. what do you think is happening? I checked register config 16 and it seems that qmc_phaseab is zero.
Thanks very much,
John Reyland
