OFF|<NR1>}
MASK:LOCk?
Related Commands
MASK:SOUrce
Arguments
ON turnsonthisfeature,sothatthemask is locked to the waveform.
OFF turns off this feature.
<NR1> = 0 turns off this feature. Any other value turns it on.
Examples
MASK:LOCK? might return :MASK:LO CK 1, indicating that the mask lock to
waveform mode is enabled.
MASK:MARgin:PERCent
Sets or returns the tolerance for the mask test. A positive value expands themask
and a negative margin shrinks the mask by the specified percentage.
A series of examples showing how to use mask commands for typical tasks
is included in an appendix. (See page E-1, Mask/Limit Command Sequence
Examples.)
Conditions
This command requires a DPO4LMT application module for 4000 series models,
and an MDO3LMT application module for MDO3000 series models.

Mask
Syntax
MASK:MARgin:PERCent <NR3>
MASK:MARgin:PERCent?
Related Commands
MASK:CUSTom
MASK:USER:WIDth
Arguments
<NR3> is a floating point value that ranges from -50.0 to +50.0. The default is 5.
Examples
MASK:MARGIN:PERCENT 25 sets the mask margin percentage to 25.
MASK:MARGIN:PERCENT? might return :MASK:MARGIN:PERCENT
1.00000000000E+001
, indicating that the mask margin is set to 10%.

MASK:SOUrce
This command specifies the mask source waveform to be used during pass/fail
mask testing. Must be one of CH1 through CH4.
A series of examples showing how to use mask commands for typical tasks
is included in an appendix. (See page E-1, Mask/Limit Command Sequence
Examples.)
Conditions
This command requires a DPO4LMT application module for 4000 series models,
and an MDO3LMT application module for MDO3000 series models.

Mask
Syntax
MASK:SOUrce {CH1|CH2|C H3|CH4}
MASK:SOUrce?
Related Commands
MASK:LOCk
Examples
MASK:SOUrce CH2 sets the source waveform for the mask to channel 2.
MASK:STANdard
This command replaces the existing mask, if any, with a specified standard mask.
There are three categories of standard masks: ANSI T1.102, ITU-T, and USB.
To ensure that Mask commands are enabled, use the command APPLication:TYPe
LIMITMask.
A series of examples showing how to use mask commands for typical tasks
is included in an appendix. (See page E-1, Mask/Limit Command Sequence
Examples.)
NOTE. The only argument enumerations available for the MDO3000 series
models are
CUSTom | LIMit | NONe | USER
.
Conditions
This command requires a DPO4LMT application module for 4000 series models,
or an MDO3LMT application module for MDO3000 series models.
