N4917B Features
The N4917B software creates a stressed eye optical waveform from the following setting parameters.
Setup files contain recommended values for each lane of LR4, ER4 and SR4. Additionally the user can
adjust the parameter values if required prior to a calibration.
Settable parameters
– Data Amplitude (mV pp) *
– Sinusoidal Interferer Amplitude (mV pp) *
– Sinusoidal Interferer Frequency (MHz)
– Periodic Jitter 1 Amplitude (UI)
– Periodic Jitter 1 Frequency (MHz)
– Periodic Jitter 2 Amplitude (UI) *
– Periodic Jitter 2 Frequency (MHz)
– Random Jitter Amplitude (mUI) *
– Bit Rate (Gb/s)
– Optical Power for calibration (dBm)
– OMA for DUT test (dBm)
– Optical Wavelength (nm) (LR4/SR4 only)
– De-emphasis cursors (dB)
– ISI (dB/GHz) *
* These values will be adjusted by the software during the calibration process to meet the calibration parameter targets
Calibration & measurement parameters
– Extinction Ratio (dB)
– VECP (dB) or SEC (dB)
– J2 Jitter (UI)
– J9 Jitter (UI) or J4 Jitter (UI)
– OMA for DUT test (dBm)
– Jitter Conformance pass/fail (UI)
– Jitter Performance margin (UI)
