This MJM-631E can measure the time jitter in the 3T component of EFM modulated signals of CD players and other devices.
It separates and extracts 3T components in EFM signals, measures the jitter quantity in real time, and displays the measuring results by the meter, and LCD display.
Its T/V conversion system ensures high-speed measurement.
By resetting the judging value, whether the measuring results are acceptable (GO) or not (NO) can be displayed by LED.

FEATURES

■

The 3T jitter quantity in EFM signals can be directly read by the meter and LCD display.

■

The jitter quantity is displayed by the standard deviation (Sigma).

■

Since the jitter quantity is measured by the T/V conversion system, the jitter fluctuation quantity can be read continuously.

■

The measured jitter quantity is compared with its preset value to be able to judge whether it is acceptable (GO) or not (NO).

■

Measurement can be done at either falling or rising polarity of the 3T signal.

■

Owing to its improvements in the compensation circuit for the period, stable measurement can be done to asymmetric signals.

■

This unit can be remote-controlled by control signals.

■

This unit is a compact and lightweight jitter meter.
