I am using a 33622A model to produce arbitrary waveforms. I need to set a phase between the two output channels with good time resolution - ideally not more than 0.2 ns. For short arbitrary waveforms this works perfectly fine since there is the start phase parameter with a range from -360 to +360 degrees, and 0.1 degree resolution, which gives 7200 points per waveform cycle as resolution. But this means I am limited to waveform lengths of about 1500ns. Is there another way to set a phase or shift channel timing with good resolution?
