Commands Listed in Alphabetical Order
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) finds the absolute difference between the maximum and
minimum amplitude in the entire waveform or gated region. This measurementis
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 first pulse in the waveform or gated region.
RISe timing measurement finds the rise time of the waveform. The rise time is
the time it takes for the leading edge of the first 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 finds the true Root Mean Square voltage in the
entire waveform or gated region. This measurement is applicable only to the
analog channels.
SIGMA1 (histogram measurement) measures the percentage of points in the
histogram that are within one standard deviation of the histogram mean.
SIGMA2 (histogram measurement) measures the percentage of points in the
histogram that are within two standard deviations of the histogram mean.
SIGMA3 (histogram measurement) measures the percentage of points in the
histogram that are within three standard deviations of the histogram mean.
STDdev measures the standard deviation (Root Mean Square (RMS) deviation) of
all acquired points within or on the histogram box.
TOVershoot (total overshoot) measures the sum of the positive and negative
overshoot value over the entire waveform or gated region. This measurementis
applicable only to the analog channels.
WAVEFORMS (waveform count) measures the number of waveforms used to
calculate the histogram.
Examples
MEASUREMENT:MEAS2:TYPE FREQUENCY defines 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 defined to measure the RMS value of a waveform.
