English translation of German description:
The first in Leader's long series of professional CD Jitter Meters, the LJM-1851 is used extensively in CD manufacturing and QC applications throughout the world. Providing, in real time, both RF level and jitter readings simultaneously, the unit also speeds production throughput with rapid and accurate judgement calls. The sigma measuring mode computes the jitter within ±one standard deviation to produce a near steady state reading of jitter facilitating accurate quantitative measurements. The EFM signal level is indicated as a peak to peak value for the 3T or 11T bit component and is selected by pushing a button.
The LJM-1851 is ideal for testing and adjusting jitter amounts and HF signal levels during production of compact disc players. It can also be used for servicing and research and development.

  • X1 speed standard
  • Jitter extracted from the 3T component
  • Simultaneous P-P level of 3T or 11T components
  • Selection of peak or sigma-weighted readings
  • Polarity selction for rising or falling edges
  • Go/No-Go judgements based on present values
  • Go/No-Go for both level and jitter
  • TTL output uses No-Go as line-stop command
  • DC output of jitter and level analogs
