Examples
MASK:COPy:SOU
rce
E1Coax specifies that the source for a user-defined custom
mask (to be created with the command
MASK:COPy:USER)istobeastandard
ITU-T E1 Coaxial Pair mask.
MASK:COPy:SOUrce? might return NONE, indicating that no source has been
specified.
MASK:COPy:
USER (No Query Form)
This creates a user-defined custom mask by making a copy of the source mask
that was specified prior with the command .MASK:COPy:SOUrce The source
mask coul
d be a standard, limit or another custom mask.
A series of examples showing how to use mask commands for typical tasks
is inclu
ded 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.

Examples
MASK:COPy:USER creates a user-defined custom mask from a copy of the source
mask.
MASK:COUNt (No Query Form)
This command resets to zero the number of hits and failures for all mask segments.
