3.1 RVP901 IF Digital Receiver
The RVP Intermediate Frequency Digital Receiver (IFDR) receives and digitizes the IF signal.
The resulting digital I and Q data is sent to the RVP900 software on the radar server
computer processing into data products.
RVP901 IF Digital Receiver (IFDR) is a network-attached FGPA-based product that provides
the receive and transmit functionality needed in a weather radar signal processor. From the
sampled IF, input it generates I and Q data that is sent to the RVP902 Signal Processor over
standard Gigabit Ethernet. It provides configuration and status functionality over TCP/IP and
data transfer using UDP packet formats.
