DVD / CD Jitter Measuring Board
MODEL B-4004
(Built-in AC Power Supply)
MODEL B4004 is a DVD,CD Jitter Measuring Board to make real time measurement of the HF/RF, total T (JISX6241, ECMA-267 recommended) jitter (3T to 14T) between EFM-Plus signal and CLOCK which is regenerated from HF/RF, EFM-Plus signal through a PLL circuit from DVD,DVD-ROM drives. And it possible to measure the 3T jitter in HF/RF, EFM signal from CD,CD-ROM drives.
Measured jitter value is converted to DC output voltage. And has a remote control inputs to change the measuring modes.
The MODEL B4004 is a simple and reasonable cost jitter measuring board, which is suitable to build into your integrated and multipurpose measuring system for production line.This model has a AC Power Supply inside.
