Hi Paul,
I would like to change center frequency quickly. If I change it and then restart the object in Matlab, it runs too slow.
Can I change center frequency in real time quickly? Can the example(Receive Tone Signal Using Analog Devices AD9361/AD9364) deployed to ARM?
Thanks and Best Regards,
Ardeal

"Change center frequency" is a very vague description, as "runs too slow" is also. Can you edit the question and add more details?

- It is possible to change the CenterFrequency property while the System object is locked as it is a tunable property.Give a look at this doc page comm.SDRRxAD936x System object (R18b) to see a list of tunable properties. Tunable properties can be modified without having to release the System object.
- The Receive Tone Signal Using Analog Devices AD9361/AD9364 example you are referring to cannot be deployed on the ARM. You will have to follow these instructions Hardware-Software Co-Design if you want to deploy a model to the target. This is only available on Simulink.You should be able to create a Simulink model similar to what the example is doing. Since you are not targeting the FPGA, you can focus on the Software Interface Model.

When calling the step method, it will first setup the System object if it has not been first setup. You can give a look at the call sequence of System objects here: Summary of Call Sequence
I suggest you try to call the setup method of that System object first by doing the following:
setup(sdrReceiver)
while_loop
tic
[data, len, lostSamps] = sdrReceiver();
toc
end
This way, the first call to step should be as quick as the second since the device has been setup before.
