| FEATURES |
 |
| ■ |
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. |
| ■ |
Offset-scale meter (3% to 13%)
To adopt an Offset-scale meter, the efficient measurement can be done in one range. |
| ■ |
Jitter value indicated with %
The unit converts a time difference between a data signal and the clock into a sigma value and indicates its jitter quantity as the percentage to the clock cycle on the meter. |
| ■ |
The polarity of the measurement
It can select either + or - edge of the data signal, and also select +, - or +/- edge for jitter measurement. |
| ■ |
INHIBIT function
The inhibit function is provided to inhibit jitter measurement of faulty section. |
| ■ |
GO/NO judgment
A GO/NO result is indicated in relation to a preset jitter value. |
| ■ |
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. |
| ■ |
2T Rejection function
It can measure jitter values without 2T signal requested by Dual layer Disc measurement. |
| ■ |
Panel-lock function
The panel-lock function is provided to preserve the measurement setting conditions. |
| ■ |
Remote control function
The DATA EDGE, RANGE, LIMIT EQ. & 2T REJ. function on the front panel can be remote-controlled by control signals. |
| ■ |
Limit equalizer as option
The limit equalizer is available as option. |
