Waveform Save Menu
Automask Menu
Source---Memory Softkey
The source---memory softkey is used to select both the source of the
waveform used during an automask function, and the destination memory
pair for the resulting upper and lower limit masks. All channels, functions,
and reference waveforms are available as source selections. Memory pairs
are either ml and m2 or m3 and m4. The upper limit mask is stored in m1 or
m3, and the lower limit mask is stored in m2 or m4.
Tolerance Units Softkey
The tolerance units softkey allows you to select the vertical and
horizontal tolerance units used during an automask function to generate the
upper and lower limit masks. You can specify tolerance as divisions or in
volts and time (seconds). Once desired units are selected, use the
horiz-vert softkey to enter the tolerance.
