Applicable to Blu-ray Disc, Ideal for Analyzing Jitter of x1, x2-Speed Disc and Optical Pickup

The LE 1876 Jitter Analyzer is designed to measure the jitter conforming to Blu-ray Disc (Part 1, version 1.0, June 2002) standards. Since the Limit Equalizer (applicable to x2 speed of Blu-ray Disc standards), PLL clock regenerator, and jitter measurement section are provided as standard, x2 speed of HF signal can be measured. A large LCD panel displays jitter in histogram format, this instrument can be used for analyzing jitter.
Jitter measurement units for a DVD/CD or HFM are optionally available. Thus, jitter of DVD and CD, and HF and HFM of Blu-ray Disc can be measured using a single unit.
Optional GPIB and LAN are convenience to construct an automatic measurement system and ensure quality control.

[Features on Blu-ray Disc measurement]

• Equipped with the Equalizer conforming to Blu-ray Disc standards
  The Conventional Equalizer and Limit Equalizer conforming to x1 speed described in Blu-ray Disc standards are provided as standard. The Conventional Equalizer mode and Limit Equalizer mode are se- lectable.The boost level of pre-Equalizer can be varied.
• Applicable to three types of media
  Jitter of Blu-ray Disc with disc capacity of 23.3 GB, 25.0 GB, and 27.0 GB can be measured.
• Measures the jitter of all-T components conforming to Blu-ray Disc standards
  (Also applicable to x2 speed)
  Measures all components of 2T to 8T and 9T of the HF (DATA) signal with respect to the CLOCK signal, then displays it as jitter in sigma format. Various jitter measurement modes (e.g., sum of all-T components, each T in pulse width mode) are also provided.
• Confirming to x2 speed prescribed in Blu-ray Disc standards
  The equalizer applicable to the x2 speed confirming to Blu-ray Disc standards is provided to measure jitter of x2 speed HF (DATA) signal.
• Three polarity modes
  Rising edge, falling edge, and both edges of HF (DATA) signal can be selected.
• Applicable dual-layer disc
  The 2T component can be eliminated in DATA to CLOCK measure- ment mode used when inspecting a dual-layer disc.
