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.
Group
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.

In addition to the standard masks,
LIMit, USER, and NONe can be input as well.
Returns
MASK:STANdard? returns one of the following:
NONE indicates that the mask application is not active.
USER indicates one of the following:
the current mask has been recalled from a file or
the current mask has been created from scratch using the MASK commands or
the current mask has been created by modifying one of the built-in standard
telecommunications masks.
LIMIT indicates that the mask is a limit test (template) mask.
DS1, etc. indicates that the current mask is one of the built-in standard masks.
Examples
MASK:STANdard DSO Double replaces the existing mask, if any, with a
standard ITU-T DSO Double mask.
MASK:STANdard? might return NONE, indicating that the mask application
is not currently active.
MASK:STOPOnviolation
This command stops the waveform acquisitions upon the first occurrence
of a waveform violation. You can also specify an action to be performed
when acquisitions are stopped by using the commands such as MASK:TESt:
