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.
