isCapturing

Status of capture running in background using baseband receiver or transceiver

Since R2024a

Syntax

status=isCapturing(bba)

Description

status=isCapturing(bba) returns a logical value status indicating whether the capture running in the background using the specified baseband receiver or baseband transceiver bba has finished.

Examples

Capture Data in Background with Baseband Receiver

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);

Output Arguments

status — Background capture status

1 (true) | 0 (false)

Background capture status, returned as a 1 (true) or 0 (false).

Data Types: logical

Version History

Introduced in R2024a

R2025a: Support for baseband transceiver object

The isCapturing function now enables you to status of a capture running in background using a basebandTransceiver object.
