Open Live Script

Create a baseband receiver object, specifying a radio setup configuration previously saved in the Radio Setup wizard. 

bbrx = basebandReceiver("MyRadio")
bbrx = 
  basebandReceiver with properties:

               RadioGain: 10
         CenterFrequency: 2.4000e+09
              SampleRate: 250000000
                Antennas: "RF0:RX2"
    DroppedSamplesAction: "error"
         CaptureDataType: "int16"

Request 5 s of IQ data in the background and save it to a file in the basebandData folder called capture1.mat.

mkdir('basebandData');
[dataPath,~] = capture(bbrx,seconds(5), ...
    SaveLocation='basebandData/capture1.mat', ...
    Background=true);

Check if the capture is in progress.

isCapturing(bbrx)
ans = logical
   1

Stop the capture after 1 s.

pause(1);
stopCapture(bbrx);

Check that the capture is no longer in progress. 

isCapturing(bbrx)
ans = logical
   0
