Command Description
MATHVAR? Returnsall numerical values used within
math expressions
MATHVA R:VAR <x> Sets or returns numerical values you can use
within math expressions
Measurement Command Group
Use the commands in the Measurement Command Group to control the automated
measurement system.
Up to four automated measurements can be displayed on the screen. In the
commands, these measurement readouts are named MEAS<x>, where <x> is the
measurement number.
In addition to the four displayed measurements, the measurement commands let
you specify an additional measurement, IMMed. The immediate measurement
has no front-panel equivalent. Immediate measurements are never displayed.
Because they are computed only when needed, immediate measurements slow the
waveform update rate less than displayed measurements.
Whether you use displayed or immediate measurements, use the VALuequery to
obtain measurement results.
Measurement commands can set and query measurement parameters. You
can assign some parameters, such as waveform sources, differently for each
measurement. Other parameters, such as reference levels, have only one value,
which applies to all measurements.
