s3a kit - Use sma as signal output ?

Hi,

For the Spartan-3A Starter Kit, you can use it as an input or output, but I would note that it's single-ended, using the system ground as the shield/reference.

Alex,

Have you looked into:

Generally, using a FPGA for SDR is only required when the radio is doing something other than FM, AM, SSB, or low data rate digital mod/demod.

Details a 'solution' using the Cyclone FPGA.

(This was before I gave my one day FPGA class to the TAPR folks).

Thanks but we want to just stick with xilinx as we get the tools as part of the uni program.

Have looked at the dsp 10 kits. After something a lot more flexible.

The

Just working towards setting up a student lab for sdr using fpga's and dsps(TI).

What they (professor and others) want is boards dsp and fpga on which students can program certain blocks like modulation, demodulation, encoders/decoders and the rest of the design is premade blocks.

So dsp/fpga does the audio encoding and modulation then goes to an upconverter and output/power amp. Same for the decode. Want the the students(telecomms) to learn sdr using c , vhdl and matlab

Thank you

Alex
