Time Null Menu
The time null menu sets the timing of all channels to correspond to channel 1
at the probe tip. This eliminates time discrepancies between channels
caused by variations in cable lengths. Also, you can use time null to manually
adjust for any differences in cable length by horizontally overlaying displayed
waveforms that are time-skewed.
Channel Softkey
The channel softkey selects which channel to skew as referenced to
channel 1.
Time Softkey
This is an unlabelled softkey. The time softkey shows the time null setting
between the selected channels. You can use the entry knob or keypad to
change the time null setting. The range of time null is + 70 ns.
Exit Menu Softkey
The exit menu softkey returns you to the utility menu.
