Modulation Format Flexibility is the Key for Successful Coherent Research


Ewing, NJ - April 4, 2013

Discovery Semiconductors Coherent Receiver Lab Buddy has been designed with laboratory convenience and modulation format flexibility in mind. DP-16QAM, DP-QPSK, Intradyne, Homodyne, and Heterodyne are all possibilities currently available to the end user.

The Coherent Receiver Lab Buddy works seamlessly as a universal front end with different instruments such as storage scopes, sampling scopes, custom ADC + DSP boards, among other things.
