Hello, \
\
I am currently facing an issue with ADC saturation on a USRP X310 equipped with
a UBX daughterboard. We are conducting measurements using an LTE signal and a
sinusoidal input signal, but it seems that the ADC is saturating, leading to a
loss of dynamic range in our measurements.

Thank you for your feedback and possible tracks.
- yes about decimation in host machine but computation capacity of the host
must be checked :-)
- not yet familiar with RFNOC, I will have a look
Signal analysis is done offline, but IQ data are stored continously during the
car trip , that is w
Your options are to sample at 184.32 MHz and decimate in the host machine
down to 30.72 MHz for LTE decoding, or if that isn't an option then you
need to place an RFNoC block at the output of the radio but before the DDC
which will give you an input power estimate that you can read from the host

Dear Marcus,
thank you for your answer. Just to clarify the problem a little better.
We use a UBX160 daughter card.
To have optimal SNR, an automatic gain control has been implemented based on
the max IQ value.
The sample rate is 30.72 for LTE decoding.
Unfortunately, high power exists outsi
