The DACs run at 128MS/s, thus there's a "fold" at 64MHz. There's an image in the 4rd Nyquist zone that you might be able to use, but 200 MHz is pretty close to 3fs/2 (192MHz). If you're a bit above 200M you this can probably be made to work. You'd need a bandpass filter to suppress the other images. If you've got access to a spectrum analyzer, just fire it up and see what you get. > If they are suitable , which python or C++ programs can I use as examples for > writing new program? There's python code in gnuradio-core/src/python/gnuradio/blks2impl/qam*.py that's probably usable for a transmitter.
