LE1876
Digital Processing Jitter Meter
- Equipped with Equalizer conforming to Blu-ray Disc standards Conventional and Limit Equalizers conforming to x1 speed described in Blu-ray Disc standards are provided as standard.The Conventional Equalizer and Limit Equalizer modes are selectable.The pre-equalizer boost level can be varied.
- Applicable to three types of media Jitter of Blu-ray Discs with disc capacities 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) Measure all components of 2T to 8T and 9T of the HF (DATA) signal, with respect to the CLOCK signal, and then displays it as jitter in sigma format. Measurement modes include the sum of all-T components and each T in pulse width mode.
- 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 measurement mode used when inspecting a dual-layer disc.
The LE 1876 Jitter Meter is designed to measure the jitter conforming to Blu-ray Disc (Part 1, version 1.0, June 2002) standards. Combining time interval analyzer TIA as well as digital processing methods for jitter measurement, enables accurate measurement with high throughput for adjusting and inspecting optical pickups on production lines. Since the Limit Equalizer, applicable to x2 speed of Blu-ray Disc standards, PLL clock regenerator, and jitter measurement sections are provided as standard, the x2 speed of HF signal output from a pickup can be directly applied to this instrument for measuring jitter. A large LCD panel displays jitter and histogram analysis makes this instrument ideal for production and inspection applications, as well as R&D. Jitter measurement units for a DVD/CD or HFM are optionally available.Thus, multiple jitter formats of standard DVD/CD and HF/HFM for the new Blu-ray Disc can be measured using a single unit. Optional GPIB and LAN interfaces are available for constructing an automatic measurement system and to ensure quality control.
