MWJ-6393U BD Jitter Meter Unit

* End of production

This MWJ-6393U, Blu-ray Jitter Meter unit is a built-in type and is designed for measuring and indicating the jitter components of the data signals (1-7 modulation signals) from Blu-ray Disc drives employed as input signals and the clock signal extracted by the internal PLL circuit employed as a reference signal.
It has the conventional equalizer, as standard and the boots level of it can be adjustable.
The inhibit function is provided to inhibit jitter measurement of faulty section and also, the limit equalizer is available as factory option.

FEATURES

¡½

Conventional equalizer provided as standard
The conventional equalizer conforming to Blu-ray Disc standards is provided and the boost level can be adjustable. The measurements of the media with 23.3GB, 25.0GB and 27.0GB are possible by the setting value.

¡½

The polarity of the measurement
It can select either + or - edge of the data signal, and also select +, - or +/- edge for jitter measurement.

¡½

INHIBIT function
The inhibit function is provided to inhibit jitter measurement of faulty section.

¡½

Auto frequency compensation circuit
Since an automatic frequency compensation circuit is provided, the jitter value can be read by a percent value accurately even if the clock frequency changes.

¡½

2T Rejection function
It can measure jitter values without 2T signal requested by Dual layer Disc measurement.

¡½

Remote control function
The DATA EDGE, RANGE, LIMIT EQ. & 2T REJ. function on the front panel can be remote-controlled by control signals.

¡½

Limit equalizer as option
The limit equalizer is available as option.

¡½

AC power operating is available

¡½

A casing design possible by request
