the 3T jitter element in EFM signal for production line. MODEL-3901 can generates accurate modulated 3T signal and BI-PHASEsignal.
As its standard features, it has the memory capability to store and recall the settings, GP-IB and RS232C inter-face. Optional functions
are signal generators to generate DVD signal (artificial EFM+ “8/16” modulated signal) for the calibration. It is used for a standard signal
generator to calibrate the total T DVD jitter meter, which has a phase lock loop circuit in its data signal input applies for DVD pick up anddrive production line. This artificial EFM+ signal is generated by DDS (Direct Digital Synthesis) method with virtual reference clock.
Phase modulator that has an artificial noise source applies to generate this artificial EFM+ “DATA” output signal.
