The DSC-R413 is an O/E instrument designed to convert DP-QPSK optical data to differential electrical signals. The R413 offers several user-adjustable characteristics such as RF gain, bandwidth, and mode of operation (AGC or manual gain control) and is ideally suited for a variety of applications. Additionally, the DC photocurrents of the balanced receivers are available for monitoring. This new computer controlled DSC-R413 is now available in two modes: single polarization & dual polarization, it's also IoT compatible.
