The usrp2_fft python code was recently changed to use that adc_rate() call, although the actual implementation returns the value to the input pointer parameter.
Just change that line in usrp2_fft back to what it was so you can at least test it: From: input_rate = self.u.adc_rate() / self.u.decim() To: input_rate = 100e6/options.decim This simply a quick fix, I'm assuming the adc_rate function will be changed to return the value the same way as decim() does. ------------------------------------------- Timothy R.
