Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 495
:MTESt:SCALe:X1
(see page 1088 )
Command Syntax
:MTESt:SCALe:X1 <x1_value>
<x1_value> ::= X1 value in NR3 format
The :MTESt:SCALe:X1 command defines where X=0 in the base coordinate
system used for mask testing. The other X- coordinate is defined by the
:MTESt:SCALe:XDELta command. Once the X1 and XDELta coordinates are
set, all X values of vertices in the mask regions are defined with respect
to this value, according to the equation:
X = (X *
Δ
X) + X1
Thus, if you set X1 to 100 ms, and XDELta to 100 ms, an X value of 0.100
is a vertex at 110 ms.
The oscilloscope uses this equation to normalize vertices. This simplifies
reprogramming to handle different data rates. For example, if you halve
the period of the waveform of interest, you need only to adjust the
XDELta value to set up the mask for the new waveform.
The X1 value is a time value specifying the location of the X1 coordinate,
which will then be treated as X=0 for mask regions coordinates.
Query Syntax
:MTESt:SCALe:X1?
The :MTESt:SCALe:X1? query returns the current X1 coordinate setting.
Return Format
<x1_value><NL>
<x1_value> ::= X1 value in NR3 format
