Hi,

Can you kindly tell me how to do that? Because I am using GNU Radio with the USRP N210 and the uhd sink block basically consists of the parameters for configuring the USRP device. How can I do that during simulation?

Thanks!

This is a good question for the discuss-gnuradio mailing list, to which I have cross-posted, and the conversation can continue on there.

Any of the parameters in a block can be tied to a variable in GRC, and many of the parameters are also programmable using the
  message port on the UHD sink block.

The details of "how do I make my software do that" requires more input about what your software is supposed to do, what your
  level of programming experience is, etc.

Yes, TX gain, frequency, etc, are all changeable at runtime--they aren't just "setup only" parameters.

Hi,

 

Is it possible to change the transmitted power just before the signal is about to be transmitted during a simulation sending some data. I know that you can configure TX Gain but can you keep changing it?

 

For example the first 100 packets for a certain amount of time have this much power and the next 100 have a different value of power. Is this possible with USRP N210 ?

 

Best,

Annie
