[USRP-users] Re: [X310] set_command_time introduces unexpected delay dependent on sampling rate.

2025-03-27 Thread je . amghar
Thank you both, Marcus and Rob, for your responses! That clarifies things—filter latency in the FPGA explains the dependency on sample rate. I hadn’t fully considered that before. A signal change at the antenna takes time to propagate, and with different filters engaged at varying sample rates,

[USRP-users] [X310] set_command_time introduces unexpected delay dependent on sampling rate.

2025-03-26 Thread je . amghar
I'm using timed commands to set the RX gain at a precise moment with the following command: set_command_time(md.time_spec + uhd::time_spec_t(0.02), 0); However, I noticed that there is a delay between the specified time and the actual time when the gain is applied. This delay is significantly l

[USRP-users] ADC saturation problem in USRP X310

2024-10-18 Thread je . amghar
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. Test

After developing a C++ program and placing it in **`/uhd/host/utils`**, I included it in **`CMakeLists.txt`**. However, when attempting to build the program using **`make`** within **`/uhd/host/build`**, UHD is reporting that it's unable to locate the C++ library I've used, specifically when inc

[USRP-users] Synchronize UBX-40 v1 Vs WBX-v3 + simple GDB

2024-01-17 Thread je . amghar
Hi,\ I am currently conducting frequency synchronization tests on two USRP X310 devices, each equipped with different daughterboards – the first with a UBX-40 v1 Dboard and the second with a WBX-v3 simple GDB Dboard. In my setup, I am using an R&S SMF 100A generator to produce a sine wave spanni
