Mask Test Commands
SCALe:X1
SCALe:X1
Command :MTESt:SCALe:X1 <x1_value>
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
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 x
∆
X) + X1
Thus, if you set X1 to 100 m s, and XDELta to 100 m s, an X value of 0.100 is a
vertex at 110 m s.
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.
<x1_value>
A time value specifying the location of the X1 coordinate, which will then be
treated as X=0 for mask regions coordinates.
Example
This example sets the X1 coordinate at 150 ms.
10 OUTPUT 707;":MTEST:SCALE:X1 150E-3"
20 END
Query :MTESt:SCALe:X1?
The :MTESt:SCALe:X1? query returns the current X1 coordinate setting.
Returned Format
[:MTESt:SCALe:X1] <x1_value><NL>
Example This example gets the current setting of the X1 coordinate from the oscilloscope
and prints it on the computer screen.
10 DIM Scale_x1$[50]
20 OUTPUT 707;":MTEST:SCALE:X1?"
30 ENTER 707;Scale_x1$
40 PRINT Scale_x1$
50 END
