PPULSECount is
the count of positive pulses.
PWIdth (positive width) is the distance (time) between the middle reference
(default = 50%
) amplitude points of a positive pulse. The measurement is made
on the rst pulse in the waveform or gated region.
RISe timing
measurement nds the rise time of the waveform. The rise time is
the time it takes for the leading edge of the rst pulse encountered to rise from a
low reference value (default is 10%) to a high reference value (default is 90%).
This measurement is applicable only to the analog c hannels.
RMS amplitude measurement nds the true Root Mean Square voltage in the
entire waveform or gated region. This measurement is applicable only to the
analog channels.
Examples
MEASUREMENT:IMMED:TYPE FREQUENCY denes the immediate measurement to
be a frequency measurement.
MEASUREMENT:IMMED:TYPE? might return :MEASURE MENT:IMMED:TYPe RMS
indicating that the immediate measurement is the true Root Mean Square voltage.
MEASUrement:IMMed:UNIts? (Query Only)
Returns the units of the immediate measurement:
