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:

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.
