They are mostly different. All the RFX boards are similar, but the RFX uses a different front end from the TVRX, DBSRX and the new boards still in development. > Are the amplifiers setup in a linear or logarithmic mode?

I think you could create a generic "rx power estimator" module on the FPGA that used the ADC output and some configuration registers that were poked at by the host code when the daughterboards are configured. From the host point of view this doesn't add much value, as you could more easily just do the same calculations on the host. If you need the value as part of an AGC loop, though, obtaining it on the FPGA is needed for tight control. (I haven't looked into controlling the RFX board gain from the FPGA. Matt is better to answer this one.) -- Johnathan Corgan Corgan Enterprises LLC http://corganenterprises.com _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
