Mask Test Commands
SCALe:Y1
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:
Y = (Y x (Y2 - Y1)) + Y1
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.
10 OUTPUT 707; ":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.
