400G Optical Manufacturing Analysis Software

DSA8300 400G-M4 optical analysis software for four channel TDECQ

DSA8300 400G-M4 optical analysis software for four channel TDECQ

The DSA8300 400G-M4 is a PC based application for PAM4 optical signal validation. The 400G-M4 application supports four channel simultaneous acquisition and integrated receiver equalization with support for both auto optimization and user defined equalizer tap values. Adjust transmitter characteristics using the built-in Laser Tuning Mode for fast feedback on measurements.

Key features
  • PC based application for PAM4 optical signal validation for repeatable, reliable measurements
  • Support for 4 channel simultaneous acquisition
  • Automated TDECQ measurement for PAM4
  • Support for bandwidth enhancement filter for 4th order Bessel-Thomson response
  • Support for customer defined filters
  • Laser tuning for fast transceiver characterization

PAM4 measurements

The DSA8300 400G-M4 dashboard style configuration panel enables quick and easy configuration of all necessary parameters for PAM4 analysis.

The PAM4 analysis package provides a comprehensive set of measurements for manufacturing test. TDECQ analysis automates a complex optical PAM4 measurement used to characterize the optical transmitter vertical eye closure.
