No. DVB-S uses simple QPSK modulation, DVB-C uses different kinds of QAM 
 and DVB-T is using a more complicated OFDM scheme in order to wipe out 
reflection and interference effects of multiple transmitters on the same 
frequency.

I suppose you want to evaluate both.

no, it can't. You would have to replace the Tuner/Synthesizer/ 
Downconverter module. What you want to do -- do you have your own DVB-T 
transmitter on 2GHz??
