PKPKNoise meas
ures the maximum range of the waveform amplitude
variance measured within either the eye aperture (for NRZ and RZ
waveforms) or the center of the measurement region (Pulse waveforms).
AOPTPWRDBM measures the true average p ower of an optical signal expressed
in decibels referenced to 1 mw.
RMS measures the true root mean square of the waveform within the
measurement region.
ACRMs measures the root mean square, minus the DC component, of the
waveform within the measurement region.
CRMs measures the root-mean-square voltage of the waveform within the first
period of the measurement region.
CMEan measure s the arithmetic mean of the waveform over the first cycle
of the measurement region.
SNRatio measures the ratio of the amplitude of the signal to the noise within
either the eye aperture (for NRZ and RZ waveforms) or the center of the
measurement region (Pulse waveforms).
AOPTpwr measures the True average power of an optical signal expressed
in watts.
GAIN measures the amplitude gain between two waveforms.
OMA measures the optical modulation amplitude, either at the eye crossing
(for NRZ waveforms) or a t the specified center apertures of the high and
low states (Pulse waveforms).
RISe me asures the time interval between the waveform crossing the
low-reference and high-reference levels o n a rising edge.
FALL me asures the time interval between the waveform crossing the
high-reference and low-reference levels on a falling edge.
PERIod measures the time interval between two consecutive crossings on the
same slope of the waveform at the mid-reference level.
FREQuency measures the reciprocal of the Period of the waveform.
PCROss measures the time at which the waveform crosses the mid-reference
level o n a rising edge.
NCROss measures the time at which the waveform crosses the mid-reference
level on a falling edge.
PWIdth measures the time interval between consecutive rising and falling
edges, measured at the m id-reference level.
NWIdth measures the time interval between consecutive falling and rising
edges, measured at the m id-reference level.
