Mask Test Commands

Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 465
:MTESt:SCALe:Y1
Command
:MTESt:SCALe:Y1 <y_value>
The :MTESt:SCALe:Y1 command defines where Y=0 in the coordinate
system for mask testing. All Y values of vertices in the coordinate system
are defined with respect to the boundaries set by SCALe:Y1 and SCALe:Y2
according to the equation:
Thus, if you set Y1 to 100 mV, and Y2 to 1 V, a Y value of 0.100 in a
vertex is at 190 mV.
<y1_value>
A voltage value specifying the point at which Y=0.
Example This example sets the Y1 marker to - 150 mV.
myScope.WriteString ":MTEST:SCALE:Y1 -150E-3"
Query
:MTESt:SCALe:Y1?
The SCALe:Y1? query returns the current setting of the Y1 marker.
Returned Format
[:MTESt:SCALe:Y1] <y1_value><NL>
Example
This example gets the setting of the Y1 marker from the oscilloscope and
prints it on the computer screen.
Dim strScale_y1 As String
myScope.WriteString ":MTEST:SCALE:Y1?"
strScale_y1 = myScope.ReadString
Debug.Print strScale_y1
Y = (Y × (Y2 - Y1)) + Y1
