Examples
MASK:USER:VSC
ALE200E-3
sets the user mask nominal vertical scale to
200 millivolts per division.
MASK:USER:VS
CALE?
might return :MASK:USER:VSCALE 1.0000E-3,
indicating that the nominal vertical scale of the displayed mask is set to 1 millivolt
per division.
MASK:USER:
WIDth
This command specifies the nominal bit width value, in seconds, to be used for
a user-defined custom mask. This is the time of one bit of data where bit width
=1/(data
rate of the signal).
NOTE. Width is set to the scope's horizontal time per div setting at the time the
mask is created. If you create a mask, e xtract the definition, modify width, then
recall the modified mask definition, you will get the same mask you originally did.
If you change the width after the mask has been recalled, you will modify the
mask ratio metrically; i.e., if you increase it by a factor of two, the mask display
become
s twice as wide, and the mask segment points are recalculated.
A series of examples showing how to use mask commands for typical tasks
is in
cluded 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.

Arguments
<NR3> is a floating point number that indicates the nominal bit width value in
seconds.

MASK:USER:WIDTH 648E-9 sets the nominal bit width value of the user mask to
648 nanoseconds (1.544 Mbits/second).
