In the previous procedure, we used the default setup of the Skew parameter (which is detecting positive edges on
both signals at 50%). We also inverted C3 in order to make C2 and C3 both have positive edges at the same
time.
Alternately, we clearly could have not inverted C3 and instead selected the Skew clock 2 tab in the P1 parameter
menu and set the oscilloscope to look for negative edges on the second input (C3). However, it is somewhat
agreed that the previous procedure looks much more aesthetically pleasing from the display as it shows C2 and
C3 with the same polarity.
