Hi all,
when using 3 X310 USRPs (TwinRX, UHD 3.15 LTS) synchronized via the CDA-2990
Octoclock (10MHz Ref and PPS distributed with length-matched cables), we are
observing deviations of up to two samples (e.g. one board late, one early)
between the individual devices.
We are seeing these
Hi!
We are using multiples N320 (UHD 3.14) and we want to synchronize our setup
using the White Rabbit protocol and using the N320 as the WR Slave and the
Master being an OPNT Switch.
We have to be able to stream the IQ over the QSFP+ port (seen as sfp0) and use
the SFP0 as the WR input so we

Hi everyone,
We are currently trying to connect the N320 (configured with the XG image) to

Hi,
We received our N320 and started doing some basic RX tests on it and everything
seems ok. We were able to get an emitted chirp and display it using GQRX.
However, when calling the set_rx_bandwidth() UHD function and then reading the
actual RX bandwidth, it always read back 250MHz. Using
Hi everyone!
We recently bought an E310 to try some very wide band acquisition (from 1GHz to
5GHz) in the fastest way possible. I read about fastlock profiles and was able
to do some early tests by adding the SPI sptr to the UHD tree and retrieving in
the code:

Hello all,
I recently purchased 4 N210s and installed 4 new UXB-40 daughter cards.
When I run uhd_usrp_probe on each of the 4 N210s it fails to identify and
returns an unknown ID and name.
I've run the probe from two different machines (Ubuntu 16.04 and Xubuntu 16.04).
I've run the probe with
