:MTESt:SCALe:XDELta

Command Syntax
:MTESt:SCALe:XDELta <xdelta_value>
<xdelta_value> ::= X delta value in NR3 format
The :MTESt:SCALe:XDELta command defines the position of the X2
marker with respect to the X1 marker. In the mask test coordinate system,
the X1 marker defines where X=0; thus, the X2 marker defines where X=1.
Because all X vertices of the regions defined for mask testing are
normalized with respect to X1 and
vertices to stay in the same locations with respect to X1 and
many applications, it is best if you define XDELta as a pulse width or bit
period. Then, a change in data rate without corresponding changes in the
waveform can easily be handled by changing
The X- coordinate of polygon vertices is normalized using this equation:
X = (X *
The X delta value is a time value specifying the distance of the X2 marker
with respect to the X1 marker.
For example, if the period of the waveform you wish to test is 1 ms,
setting
