Syntax 1
MASK:SOUrce {CH[1-4]|MATH[1-4]|REF[1-4]}
Syntax 2
MASK:SOUrce?
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>
Selects a math waveform to be compared against the specified mask.
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
specified, the default, Main, is used.
Example 2
MASK:SOURCE?
Might return
:MASK:SOURCE CH1,MAIN
indicated that the Channel 1 waveform will be compared against the
