19 :MEASure Commands
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
