Apex OCSA-APX High Resolution Complex Optical Spectrum Analyser

Product Code:

OCSAAPX

Manufacturer: APEX Technologies

Ideal solution for Telecommunication applications, the APEX Optical Complex Spectrum Analyzer (OCSA) Series is equipped with the high resolution of 5 MHz/0.04 pm, as well as other resolution bandwidth from 20 to 140 MHz. Additionally, the complex OSAs offer additional time domain measurement capability, including intensity, phase and chirp measurements

Available options:

The optical output of the built-in Tunable Laser Source (TLS), which could also be used for component analysis (tracking function);
2 additional PM inputs
Polarisation analysis is possible through a polarimeter (SOP, DOP, and PER measurement). This option can displacy three polarisation modes: Jones graph, Poincaré sphere and Stokes parameter oscilloscope.
