[USRP-users] Considerations on resampling inside USRP firmware

2020-07-14 Thread Richard J. Muri via USRP-users
Hello, I'm working on a project using x310s where different stakeholders desire different sampling rates, some of which are not natively support by the x310. One stakeholder wants to put a fractional resampling filter at the ingress and egress of the FPGA inside the USRP. For instance, I m

Joe: The input levels that cause distortion vary quite a bit from daughtercard to daughtercard, and even within a daughtercard there will be variability depending on frequency. The performance data can be consulted for this: https://files.ettus.com/performance_data/ What you’re looking for i

Arash, Marcus L.’s response has some definitive info in the links. For example, in the TwinRX link it is stated: > Never apply more than +10 dBm of power into any RF input. So there you have it. Thanks for the details Marcus. Regards, Joe > On Jul 14, 2020, at 7:55 AM, Marcus D. Leech

Arash, While Marcus’ response is certainly correct it does little in providing a practical answer to your question. I use an X310 with TwinRX daughterboards and have found that it is inadvisable to use input levels to the TwinRX daughterboard greater than -30dBm because higher levels than t
