Hi ,everyone I want to do some realtime application with NI-USRP 2920, so I care about the time delay of burst packets communication.
For the finite transmission , when we configure a Time Start Trigger and set the time to generate the first sample.
It costs 5-6 milliseconds to setup the USRP to write the first sample into the buffer, and then generate.
However, if we don't configure a time start trigger, it costs 52 milliseconds to setup the USRP and generate the first sample.
I want to know what is the difference between the two mechanism.
There are some papers focus on the time delay of GNU Radio and USRP, there results about time delay usually less than 1 millisecond,
I want to ask why the NI-USRP and Labview so slowly ? How can improve its performance ?
The time delay test vi is attached! Any one can have a test.
Thanks
