QFACtor measur
es the ratio of the amplitude of the eye to the total RMS
noise on the High and Low levels.
DISTDUty meas
ures the ratio of the time interval between the points where
the rising and the falling edges cross the mid-reference level and the bit time
of the waveform.
BITTime measures the time interval between the start of two successive data
bits of the waveform.
BITRate measures the inverse of the time interval between the start of two
successive data bits of the waveform.
TIMCROss measures the horizontal position (measured from the trigger p oint)
of the eye crossing.
SUPRSDB measures the ratio of the average High level to the suppressed level
measured between two consecutive RZ pulses expressed in decibels (dB).
SUPRSPCT measures the Ratio of the average High level to the Suppressed
level measured between two consecutive RZ pulses expressed in percentage
(%).
SUPRSRATIO measures the Ratio of the average High level to the Suppressed
level measured between two consecutive RZ pulses expressed as a simple
ratio.
PULSESym measures the extent to which the R Z pulse is symmetrical around
the peak at the mid-reference level. The pulse peak is the center of the interval,
sized to Eye Aperture, which yields the maximum mean vertical value.
Examples
MEASUREMENT:MEAS3:TYPE FREQUENCY definesMeasurement3asa
measurement of the frequency of a waveform.
MEASUREMENT:MEAS3:TYPE? might return MEASUREMENT:MEAS3:TYP E
RMS
, indicating that Measurement 3 is defined to measure the RMS value of
a waveform.
MEASUrement:MEAS<x>:UNIts? (Query Only)
This query only command returns the units for the measurement slot specified
by x, which can be 1 through 8. You firstmusthavedefined the measurement
slot using the MEASUrement:MEAS<x>:TYPe command before the units can
be returned.
