The MWJ-6392E is designed for measuring and indicating the jitter components of the data signals with internal PLL clock signal employed as a reference signal from RF signals of DVD, DVD-ROM and other relative devices.
It indicates the measured jitter values by percent (%) in the SIGMA mode and can select either + , – or + /- edge of the data signals as the reference trigger clock edge.
It has the digital equalizer circuit which is adjustable according to the characteristics of Pick-ups, and the INHIBIT function is provided to inhibit jitter measurement of faulty section.
In addition, it indicate whether measured values are acceptable or not by GO or NO-GO lamp by presetting a criterion value.
FEATURES
It has the digital equalizer circuit which is adjustable according to the characteristics of Pick-up.
The jitter quantity can be directly read by the meter and LCD indicator.
This unit converts a time difference between a data signal and the clock into a sigma value and indicated its jitter quantity as the percentage to the clock cycle on the meter indicator.
Changes in the jitter can be read continuously, due to T/V conversion method of measurement.
It can select either + or -edge of the data (EFM Plus) signal as the trigger edge, and also select +, – or +/- edge for jitter measurement.
The INHIBIT function is provided to inhibit jitter measurement of faulty section.
A GO/NO-GO result is indicted in relation to a preset jitter value.
The panel-lock function is provided to set measuring conditions.
A remote control function is provided.
