Introduction to
:MEASure
Commands
The commands in the MEASure subsystem are used to make parametric
measurements on displayed waveforms.
Measurement Setup
To make a measurement, the portion of the waveform required for that
measurement must be displayed on the oscilloscope screen.
Measurement Error
If a measurement cannot be made (typically because the proper portion of the
waveform is not displayed), the value +9.9E+37 is returned for that measurement.
