This is very interesting. I am trying to set the rx bandwidth on a
N321 for a while now.
Is there any workaround? Our bandwidth seems stuck at 8MHz while our
application needs much more.
Thanks
Lorenzo
Sorry, on the N32x series, the analog bandwidth in front of the ADC is
*fixed*, and bandwidth delivered to your application is controlled
strictly by the selected sample-rate.

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.
