Description:
The DSC-R422 is a linear AGC balanced receiver
ideally suited for a variety of analog and digital
applications, such as coherent 100G / 200G /
400G systems. The R422 offers a variety of useradjustable
characteristics such as RF gain, output
amplitude, and mode of operation (AGC or manual
gain control). The R422 offers 33 GHz bandwidth,
gain up to 2800 V/W, low power dissipation and a
peak detector function. The R422 is available in a
GPPO module package as well as in Discovery’s
Lab Buddy instrument. The Lab Buddy is offered
with built-in firmware which allows it to be
integrated with other pieces of equipment in
automated test setups.
