Anritsu Corporation has introduced the measurement function (MS9740B-020) for its optical spectrum analyser MS9740B to evaluate pulsed laser diode (LD) chips. This new solution redu­ces the test time for pulsed LD chips, contributing to improved production efficiency of high-power LD chips.

Product features

  • Reduced tact time for pulsed LD chips: The new MS97040B-020 solution accelerates optical spectrum evaluation by eliminating the need for a trigger signal.
  • Assured measurement reproducibility for high-power LD chips: This solution assures measurement reproducibility of ±1.4 dB for the side mode suppression ratio (SMSR). The reduced SMSR variation improves LD chip yield and enhances production efficiency.
