Examples
MEASUREMENT:MEAS1:UNITS? might return :MEASUREMENT:MEAS1:UNIts %
indicating units for measurement 1 are set to percent.
MEASUrement:MEAS<x>:VALue? (Query Only)
Returns a calculate value for the measurement specified by <x>, which ranges
from 1 through 8 (only 4 in MDO3000 models).
NOTE. This is the same value as displayed on-screen. If measurement statistics
are enabled, a new value is calculated with every waveform. In addition, this
value is updated approximately every 1/3 second. If you are acquiring a long
acquisition record, the oscilloscope may take longer to update.
