Standard complex for control over digital interfaces (PDH/SDH) of communication channels

Developed and operated since 2016

Composition:

  • standard installation for measuring and generating phase jitter;
  • oscillograph LeCroy WR610Zi;
  • generator ArbStudio 1102D;
  • frequency meter CNT-90XL

Metrological characteristics:

  • Range of signal amplitude measuring: from 0,5 to 3 V;
  • NSE of amplitude measuring: ± 0,5 %;
  • range of pulse time measuring: from 2 to 268 ns;
  • NSE of time measuring: ± 0,5 %;
  • modulation frequency signal phase jitter: 0,02; 0,1; 0,2; 0,4; 1; 10; 20; 50; 100; 400;800; 3500 kHz;
  • NSE of modulation frequency: ± 3 %;
  • limits of phase jitter amplitudes set: 0,05 – 50 UI depending on modulation frequency and data transfer speed;
  • NSE of phase jitter amplitude set: from 0,5 to 1,5 % from span of phase jitter set and transfer speed;
  • limits of phase jitter amplitudes measured: 0,05 – 20 UI;
  • NSE of phase jitter amplitude measured: from 0,5 to 1,0 %

Scope of application:

  • information and telecommunication technologies,
  • information transfer devices etc.
  • standard complex is designed for reproduction, storage and transfer of parameters of joints of digital transfer channels and baseband paths of entire automated communication system
