MATH<x>:UNIt
s? (Query Only)
This query only command returns the math units for the specified math waveform.
The x argument can be 1 through 8, specifying math waveforms M1 through M8.
The instrume
nt will attempt to determine the appropriate units for the result of the
math expression that generates the math waveform. The default is UNDEFINED
unless one of the following rules can be applied:
If the resultant waveform is unitless, a "U" is displayed for the unit label.
Plus (+), M
inus (-), Average, Envelope, and Filter functions use the unit label
of the source operands for the vertical axis readout and the horizontal axis unit
label of the source operands for the horizontal axis readout. If the units for the
sources are not the same, then the result is unitless.
An integration function concatenates the vertical axis unit label and the
horizontal axis label of its source operand for the vertical axis readout (for
example, Vs) and the horizontal axis unit label of the source operands for
the horizontal axis readout.
A differential function concatenates the vertical axis unit label and the
horizontal axis label of its source operand with a slash (/) inserted between
label
s (for example, V/s) and the horizontal axis unit label of the source
operands for the horizontal axis readout.
The m
ultiply function (*) concatenates the vertical axis unit labels of its source
operands for the vertical axis readout (for example, VV) and the horizontal
axis unit label of the source operands for the horizontal axis readout.
The divide function concatenates the unit labels of its source operands with a
slash (/) inserted between the labels (for example, V/V) and the horizontal
axis unit label of the source operands for the horizontal axis readout.
The log, ln, sqrt, and e
x
function results are unitless.

Syntax
MATH<x>:UNIts?
Examples
MATH3:UNITS? might return MATH3:UNITS "V", indicating that the units for
Math 3 waveform are volts.
MATH<x>:WFMLabel
This command sets or queries the label associated with the math waveform
specified.
