[Discuss-gnuradio] uhd.usrp_source COMPLEX_INT16 vs COMPLEX_FLOAT32

2011-10-14 Thread Kyle Zhou
the usrp_source in gr-uhd has two io_type uhd.io_type.COMPLEX_INT16 and uhd.io_type.COMPLEX_FLOAT32. To my understanding, the float version will produce samples between -1.0 and +1.0. What is the range of the int16 version? If the same signal is fed into the antenna, what is the relative scaling
