The RVP7/main signal processor is replaced by the RVP901-WSP IF Digital Receiver. The
RVP901-WSP meets or exceeds the specifications of the RVP7 and is designed to mount in a
similar fashion as the RVP7, although its footprint is slightly larger. The RVP7 fiber optic link
carrying the RVP I and Q interface to the RxNet7 is replaced by an Ethernet interface to the
RVP902-WSP Processor. The RVP902-WSP Processor also replaces the Ampro embedded
computer to provide the same RIM API control and status functions as the original
implementation.
The ASR9 WSP connections on the original RxNet7 front panel have been preserved and
implemented on the RCP903 ASR9 Panel on J1 and J2 and connects to the existing WSP
interface hardware in the ASR9 radar. The panel also preserved the serial interfaces provided
by the RxNet7 on J3 and J4. The RIN-PE connection to the Mercury computer have been
obsoleted and the I/Q data path for the ASR9 will now pass to the RVP902-WSP Processor
over Ethernet on J5. The required trigger and header information is provided to the RVP901-
WSP using its general purpose I/O interface from J6 on the RCP903 ASR9 Panel. This allows
the RVP902-WSP Processor to synchronize the ASR9 and RVP900 data streams.
In addition to the RCP903, RVP901-WSP, and RVP902-WSP hardware, an Ethernet switch is
provided to allow connections from the RVP901- WSP and RCP903 ASR9 Panel to
communicate with ETH1 on the RVP902-WSP Processor, a AC/DC power supply to power
the RCP903 ASR9 Panel and an AC power strip to power the RCP903 supply and RVP902-
WSP Processor are provided. All of the components in Bay 3 are designed to
fit in the same
area as the original RxNet7 solution. The block diagram for the new RVP900 base ASR9
WSP solution is shown in the following
figure and a table with the RVP900-WSP
components is shown in the following table.
