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: 200000000
                Antennas: "RFA:RX2"
    DroppedSamplesAction: "error"
         CaptureDataType: "int16"

Capture 1 s of IQ data in the background.

mkdir('basebandData');
capture(bbrx,seconds(1),Background=true);

Check if the capture is in progress.

isCapturing(bbrx)
ans = logical
   1

Wait for the capture to complete.

while isCapturing(bbrx)
    pause(0.1);
end

Check that the capture is no longer in progress. 

isCapturing(bbrx)
ans = logical
   0

Retrieve the outputs of the capture operation and load the captured IQ data into the workspace.

[data,timestamp,droppedSamples] = captureOutputs(bbrx);
