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:

mples 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:TESt:HARDCopy,
MASK:TESt:SRQ:FAILure
Arguments
ON stops waveform acquisition
on the first occurrence of a mask violation.
OFF turns this feature off.
<NR1>=0 turns this feature off ; any other value turns it on.
Examples
MASK:STOPONVIOLATION ON sets the instrument to stop waveform acquisition
on the first occurrence of a waveform violation.
MASK:STOPONVIOLATION? might return :MASK:STOPONVIOLATION ON,
indicating that the waveform acquisitions will be stopped upon the first occurrence
of a waveform violation.
MASK:TEMPLate:CREATEmask (No Query Form)
This command, used for limit mask testing, causes a template mask to be created
based on the settings of the MASK:TEMPLate:SOUrce, MASK:TEMPLate:
TOLerance:HORizontal,andMASK:TEMPLate:TOLerance:VERTical
commands. If you do not specify horizontal or vertical tolerances, the default
tolerance of one minor division will be used.
