Arguments
H CH<1-4>
Selects a channel waveform to be compared against the specified
mask. The range for is 1 through 4.
H MATH<1-4>

The range for is 1 through 4.
H REF<1-4>
Selects a reference waveform to be compared against the specified
mask. The range is 1 through 4.
Example 1
MASK:SOURCE CH1
Enables CH1 to be compared against the mask. Since a timebase is not
