Math and Measure
Measurement
Description
Fall time
(fall)
Duration of pulse waveform's falling transition from 90% to 10% of the amplitude averaged for
all falling transitions between the measurement gates. On signals not having two major levels
(triangle or saw-tooth waves, for example), top and base can default to maximum and minimum,
giving less predictable results.
Fall@level
(fall@lv)
Fall at level: Duration of pulse waveform's falling edges between user-specified transition
levels.
Threshold arguments specify two vertical values on each edge used to compute fall time:
lower = lower thresh. x amp/100 + base
upper = upper thresh. x amp/100 + base
First
Indicates value of horizontal axis at left cursor.
Frequency
(freq)
Period of cyclic signal measured as time between every other pair of 50% crossings. Starting
with first transition after left measurement gate. The period is measured for each transition pair.
The reciprocal of each period measurement is calculated as the frequency.
Freq@level
(freq@lv)
Period of cyclic signal measured as time between every other pair at the specified level. Start-
ing with first transition after left measurement gate. The period is measured for each transition
pair. The reciprocal of each period measurement is calculated as the frequency.
FWHM
Measures the width of the largest area histogram peak at half of the populationof the highest
peak.
FWxx
Measures the width of the largest area histogram peak at xx% of the population of the highest
peak.
Half Period
(hper)
Half period of a waveform.
Hist ampl
(hampl)
Difference in value between the two most populated peaks in a histogram.
Hist base
Value of the left-most of the two most populated histogram peaks.
Hist max pop
Peak with maximum population in a histogram.
Hist maximum
Value of the highest (right-most) populated bin in a histogram.
Hist mean
Average or mean value of data in a histogram.
Hist median
Value of the 'x' axis of a histogram that divides the population into two equal halves.
Hist minimum
Value of the lowest (left-most) populated bin in a histogram.
Hist mode
Position of the highest histogram peak.
Hist pop@x
Population at bin for specified horizontal coordinate.
Hist range
Calculates range (max-min) of a histogram.
Hist rms
Root mean square of the values in a histogram.
Hist sdev
Standard deviation of values in a histogram.
Hist top
Value of the right-most of the two most populated histogram peaks.
Hist X@peak
Value of the
n
th highest histogram peak. You supply the value of
n
.
Hold Time
Time from the clock edge to the data edge.
Last
Time from trigger to last (rightmost) cursor.
