PK2pk is the absolute difference between the maximum and minimum amplitude.
It can be used with both general purpose and histogram measurements.
POVershoot is the positive overshoot, expressed as:
POVershoot = 100 ×
Ꮛ
(Maximum − High)
Amplitude
Ꮠ
PWIdth is the distance (time) between MidRef (usually 50%) amplitude points of
a positive pulse.
RISe is the time that it takes for the leading edge of a pulse to rise from a low
reference value to a high reference value of its final value.
RMS is the true Root Mean Square voltage.
MEASUREMENT:MEAS3:TYPE RMS
specifies MEAS3 to calculate the Root Mean Square voltage.
MEASUrement:MEAS<x>:UNIts? (Query Only)
Returns the units for the measurement specified by MEASUre-
ment:MEAS<x>:TYPe.
Measurement
MEASUrement:MEAS<x>:UNIts?
<QString> returns ”V” for volts, ”s” for seconds, ”HZ” for hertz, or ”%” for
percent. ”A” for amps, ”W” for watts, ”?” for unknown, and ””for non-dimen-
sional units. Measurements on math waveforms can return the following units:
”V/V”, ”A/W”, ”WV”, ”W/V”, ”dBV”, ”dB/V”, ”V/A”, ”A/A”, ”WA”, ”W/A”, ”dBA”,
”dB/A”, ”VW”, ”V/W”, ”AW”, ”A/W”, ”WW”, ”W/W”, ”dBW”, ”dB/W”, ”VdB”,
”V/dB”, ”AdB”, ”A/dB”, ”WdB”, ”W/dB”, ”dBdB”,and”dB/dB”.
MEASUREMENT:MEAS3:UNITS?
might return ”%”, indicating the units for Measurement 3 are percent.
