: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
Δ
X, redefining
Δ
X also moves those
vertices to stay in the same locations with respect to X1 and
Δ
X. Thus, in
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
Δ
X.
The X- coordinate of polygon vertices is normalized using this equation:
X = (X *
Δ
X) + X1
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
Δ
X to 1 ms ensures that the waveform's period is between the X1
and X2 markers.
Query Syntax
:MTESt:SCALe:XDELta?
The :MTESt:SCALe:XDELta? query returns the current value of
Δ
X.
Return Format
<xdelta_value><NL>
<xdelta_value> ::= X delta value in NR3 format
