MJS-640 CD/DVD JITTER METER CALIBRATOR 目黑 Meguro

The MJS-640 is a versatile type and is designed as a jitter signal generator for calibrating CD Jitter Meters at 3T and DVD Jitter Meters at Total-T.
This unit can be used as a calibrator for the following models.

Calibration jitter signal
Jitter Mode
3T method: Standard speed / Clock frequency 4.3218MHz

DVD: Clock frequency 27MHz

Total-T method:
Data to Clock: Clock frequency 27MHz

Jitter Frequency
3T method: 1kHz, 10kHz, 100kHz (Sine waveform)

Total-T method: Noise

Calibration Output

3T method

Standard speed: 40, 60, 80, 120 and 160ns at p-p value / 30ns at sigma value

DVD: 5 and 9ns at signal value

Total-T method: 5, 8, 10 and 15% at sigma value

Jitter Accuracy
Accuracy: ±1.5% of 3T jitter value (Sigma value) or ±0.15ns

Residual jitter: Less than 300ps

Asymmetry
Asymmetry: OFF, +0.5T, -0.5T

Accuracy: ±5% of clock cycle or less than 2ns
