CPCI RF modem:
provides a QPSK signal for radio communication. It uses a SHARC
DSP processor and has a cPCI version 2.1 backplane interface.
A RS 232 serial link is provided.
VME RF modem is similar to the CPCI
modem. It provides 3 RF channels with a common VME bus. The VME
slave logic is implemented on a FPGA.
