LE1871
Digital Processing Jitter Meter

feature

  • Applicable to three types of disc capacity (x1 speed) Jitter of Blu-ray Disc with disc capacity of 23.3 GB, 25.0 GB, and 27.0 GB can be measured.
  • Equipped with Equalizer conforming to Blu-ray Disc standards The Conventional Equalizer conforming to Blu-ray Disc standards is provided.The boost level of Conventional Equalizer can be varied.
  • Digital processing method for quick and accurate measurement Root-mean-square value calculation using digital processing method enables quick and accurate measurements.
  • Measures the jitter of all-T components conforming to Blu-ray Disc standards 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.
  • Displaying jitter as %. Jitter component with respect to the clock signal is displayed as a percentage (%). No clock period setting is required since the clock is automatically regenerated from the HF (DATA) signal. Measurement will be made correctly even when the HF (DATA) signal deviation is 4%.
  • Three polarity modes Rising edge, falling edge, and both edges of 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 1871 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.
