I’m new to USRP so that I need to ask some fundamental things.
I’ve just purchased two USRP E100s.
I want to measure the latency of the USRP E100 in order to compare with
USRP1 and USRP2.
My intention is to measure the latency in two layers.
- Latency of UHD driver
- Latency of the USRP E100 itself.
I would like to ask any suggestion for me?
I’m using USRP E100 which is standalone device.
I’ve tried to measure the time between gruradio (user-space) and Linux
kernel (all are embeded in E100); and the time from linux kernel to fpga
(until the packet is sent).
I expect the RRT will be smaller compared to USRP1 and USRP2 due to E100
doesn’t require data transfer from usrp to host computer (via
I’m new to Usrp and gnuradio. I have no idea now.
I would like to ask any suggestion from all of you for my case.
Thank you very much in advance
