MWJ-6392

<DESCRIPTION>
The MWJ-6392 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-up.
In addition, it indicate whether measured values are acceptable or not by GO or NO-GO lamp by presetting a criterion value.

2. It has the digital equalizer circuit which is adjustable according to the characteristics of Pick-up.

3. The output terminal is equipped for the signal output after the equalizer circuit.

4. It can measure the jitter components of the data signals ( 3T ~ 14T ) to the clock signal of the internal PLL circuit and indicate by percent ( % ) in the SIGMA mode.

5. Changes in the jitter can be read continuously, due to T/V conversion method of measurement.

6. The polarity of the data signals can be selected ( positive, negative or both of edge ).
