Hello,
Just received mine yesterday, upgraded in a minute (thx Janekivi!), then started to experiment all functions, impressive. But when I tried to play with the two chanels locked, I found something which seems at first abnormal: leaving the phase at 0°, the two signals are supposed to be in phase, and guess what, they are'nt. After ome measurement, I found that there is a constant time shift of 2.8ns between them, which leads to a phase deviation from roughly 0° below 1MHz but up to 120° at 120MHz. Playing with the phase parameter, you can adjust the signals to whatever phase deviation you want, but for that you need an oscilloscope, as the 2.8ns is not only function of the frequency, but also of the amplitude (the less the amplitude, the less the time shift). Here bellow some oscilloscope display captures.
Can one of you guys confirm this behaviour as a feature and not an hardware bug of my unit? (I also tried with same results chanels coupling, chanel copy and eqphase functions)
Thanks to all
Denis
