Group
Math
Syntax
MATH[1]:VERTical:UNIts?
Examples
MATH:VERTICAL:UNITS? might return MATH:VERTICAL:UNITS "joules"
indicating that the math vertical unit label for unknown values is joules.
MATHVAR? (Query Only)
Queries both numerical values you can use within math expressions.

Returns
<NR3> are the stored numerical values.
Examples
MATHVAR? returns the values of all variables stored in locations 1 through 2.
MATHVAR:VAR<x>
This command specifies one of two different numerical values you can use within
math expressions. These values can range from -10.0e-18 to 1.0e+15; the default
values are 0.0. <x> specifies the location, 1 or 2, in which you can store values.
Stored math variables can be referenced within math expressions as VAR1 and
VA R 2 .
For example, the following command defines MATH1 as the product of Channel
1andma
th variable 1: MATH1:DEFINE "CH1 * VAR1".

Syntax
MEASUrement:GATing {OFF|SCREen|CURSor}
MEASUrement:GATing?
Arguments
OFF turns off measurement gating (full record).
SCREen turns on gating, using the left and right edges of the screen.
