Element Description Example
CH1-CH4
REF1-REF4
Specifies an an
alog channel or
reference waveform as the data source.
Referenced as <wfm> in the math
operators de
scriptions.
:MATH:DEFINE "FFT(CH1)"
Automatic m
easurements of waveforms
See also MEASUrement:IMMed:TYPe and MEASUrement:MEAS<x>:TYPe .
AMPlitude(<wfm>)
Thehighval
ue less the low value
measured over the entire waveform or
gated region.
:MATH:DEFI
NE
"AMPlitude(CH1)"
AREa(<wfm>)
Area measurement is a voltage over
time measurement. It returns the area
over the en
tire waveform or gated region
in volt-seconds. Area measured above
ground is positive; area measured
below gro
und is negative.
:MATH:DEFINE "AREA(CH1) "
BURst(<
wfm>)
Burst wi
dth: the duration of a burst
(a series of transient events) and is
measured over the entire waveform or
gated re
gion.
:MATH:DEFINE "BURST(CH1 )"
CARea(
<wfm>)
Cycle a
rea: a voltage over time
measurement. The measurement is the
area over the first cycle in the waveform
or the fi
rst cycle in the gated region
expressed in volt-seconds. The area
above the common reference point
is pos
itive, and the area below the
common reference point is negative.
:MATH:DEFINE "CAREA(CH1 )"
CMEan(<wfm>) Cycle mean: the arithmetic mean over
the first c ycle in the w aveform or the
first
cycle in the gated region.
:MATH:DEFINE "CMEAN(CH1 )"
CRM
s(<wfm>)
Cyc
le RMS: the true Root Mean Square
voltage o ver the first cycle in the
waveform or the first cycle in the gated
reg
ion.
:MATH:DEFINE "CRMS(CH1) "
DE
Lay(<wfm>,<wfm>)
Th
e time between the mid reference
(default 50%) a mplitude point of two
different waveforms. See also Phase.
:MATH:DEFINE
"D
ELAY(CH1,CH2)"
FA LL(<wfm>) The time required for the falling edge
o
fthefirst pulse in the waveform
or gated region to fall from the high
reference value (default = 90% ) to the
l
ow reference value (default = 10%) of
the final value.
