In taking a phase angle measurement it is apparent that only 1 cycle is analyzed even though multiple cycles appear on the scope. In fact the resolution gets worse the greater the horizontal timebase. Since we have some noisy signals the measurement varies considerably. Even when we put a perfect sine wave into adjacent channels we see variation of 1.4 degrees when it should be perfectly 0.0 degrees. Can the scope be setup to average several measurements on it's own or would this require external communication to transfer measurements and average on a remote PC?
