Channel Switching Delay Measurements

Solved!
Go to solution

Hi all, 

 

Assume that we have a LabVIEW code for transmitting a signal such that at each iteration of while loop, the carrier frequency is changing. We don't care how it changes, but we focus on measuring the channel switching delay. In other words, we would like to measure the time that for the USRP it takes to change the carrier frequency at each iteration of while loop.  

 

Below please see the related part of the code. I was wondering, does the indicator "Channels Switching Delay" measure the carrier frequency changing time delay in USRP? 

 

FYI, As I am measuring this way, it indicates 0ms, 1ms or 2ms whenever the carrier frequency is changing.

 

Thank you.

Hi Amir,

 

You code should work for benchmarking. If you need more than millisecond precision, you can use the High Resolution Relative Seconds.vi. Also, for benchmark testing, you could run your loop 1000 times, then subtract the values and divide by 1000 to get an average.Benchmarking.png
