[Discuss-gnuradio] Reducing the ADC sample rate

2005-11-11 Thread [EMAIL PROTECTED]
I would like to reduce the ADC sample rate from the default 62.5 MS/s. I have found the set_adc_clk_div in the usrp0_rx class. Is this still usable. I tried to use it in the follow: u = usrp.source_c() u.set_adc_clk_div(6) and I get errors? I did 'from gnuradio import usrp0' and still get th

No I have not yet made that change. I have been trying to figure out how to use it. I don't understand the brief description /*! * \brief Enable/disable automatic DC offset removal control loop in FPGA * * \param bits which control loops to enable * \param mask which \p bits to p
