PEDGECount is the count of positive edges.
PERIod is the time required to complete the rst cycle in a waveform or gated
region. Period is the reciprocal of frequency and is measured in seconds.
PHAse measures the phase difference (amount of time a waveform leads or lags
the reference waveform) between two waveforms. The measurement is made
between the middle reference points of the two waveforms and is expressed in
degrees, where 360° represents one waveform cycle.
PK2Pk (peak-to-peak) nds the absolute difference between the maximum and
minimum amplitude in the entire waveform or gated region. This measurement is
applicable only to the analog channels.
POVershoot is the positive overshoot value over the entire waveform or gated
region. This measurement is applicable only to the analog channels.
Positive Overshoot = ((Maximum - High) / Amplitude) ×100%
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 channels.
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:MEAS2:TYPE FREQUENCY denes measurement 2 as a
measurement of the frequency of a waveform.
MEASUREMENT:MEAS1:TYPE? might return :MEASUREMENT:MEAS1:TYPE RMS
indicating that measurement 1 is dened to measure the RMS value of a waveform.
MEASUrement:MEAS<x>:UNIts? (Query Only)
Returns the units associated with the specied measurement. The measurement
slots are specied by <x>, which ranges from 1 through 4.
