I hooked up an analog osciloscope on the Basic Tx daughterboard and tested the usrp_siggen.py. It seems to work!
A couple of questions: 1) what are the units of amplitude? (the default is 16e3) 2) why does the amplitude change if I change the frequency? I guess it is related to a constant multiplicative factor in the interploator? 3) What is the expected relationship between the I and Q channel outputs? I see the same signal with a phase shif, but not sure where the phase shift is comming from. Next I 'll test the usrp_oscope and report my progress to the list. Thanks for all the suggestions, Achilleas _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
