This application illustrates how you can develop Software Defined Radio (SDR) applications for the Sundance SDR8246 system using 3L Diamond.
The SDR8246 provides two C6455 TI DSPs and two Virtex4 FPGAs. When sold to universities the SDR8246 includes a Diamond kit supporting one DSP and one FPGA. If you wish to use second DSP and / or FPGA you should contact your distributor for an upgrade of Diamond.
The system
The system is made of one SMT362 and one SMT350 paired with an SMT368. The modules are held on an SMT148FX carrier board.
Samples generated by the FPGA of the SMT368 are sent to the DAC on the SMT350 to be converted to analogue signal.
The outputs of the DAC are connected to the inputs of the ADC.
The ADC digitizes the signal and the samples are sent to the DSPs for processing and display.

Note1: the SMT148-FX Spartan should be programmed with firmware ‘com.sundance.smt148-fx.sc3s1500.usb_default.sdrkit2.app’. Contact Sundance for more information.
Note2: the SMT368 should be configured to boot from Comport 0. You should set SW1 pos1, 2 and 3 to ON.
