Hello,
I noticed that RX bandwidth is fixed to 100MHz, although the AD9371
datasheet specifies an adjustable range of 8 to 100MHz. Why is this
parameter fixed?
double magnesium_radio_control_impl::set_rx_bandwidth(
const double bandwidth, const size_t chan)
{
std::lock_guard<std::recursive_mutex> l(_set_lock);
_ad9371->set_bandwidth(bandwidth, chan, RX_DIRECTION);
// FIXME: setting analog bandwidth on AD9371 take no effect.
// Remove this warning when ADI can confirm that it works.
RFNOC_LOG_WARNING("set_rx_bandwidth take no effect on AD9371. "
"Default analog bandwidth is 100MHz");
return AD9371_RX_MAX_BANDWIDTH;
}
Best regards,
Roberto
Because despite what the *datasheet* for the AD9371 says, the published
interface to change the analog RX bandwidth has no effect.
