Ken, The DAC samples at 128 MS/s, so there's a "fold" at fs/2 == 64MHz. You can hit 140 - 150 MHz and/or 88-107MHz with an image. You'll mostly likely want to use an analog bandpass filter that selects only the image you're interested in. You can try this with: $ usrp_siggen.py --const -i 32 -f 140M Hook the output of the Basic Tx up to a spectrum analyzer to see what's happening.
