stopTransmission

Stop transmission from baseband transmitter or transceiver

Since R2022a

Syntax

stopTransmission(bba)

Description

stopTransmission(bba) stops continuous IQ waveform transmission from the specified baseband transmitter or baseband transceiver bba.

Examples

Configure Baseband Transmitter and Transmit Waveform

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

bbtx = basebandTransmitter("MyRadio")

bbtx = 
  basebandTransmitter with properties:

          RadioGain: 10
    CenterFrequency: 2.4000e+09
         SampleRate: 250000000
           Antennas: "RF0:TX/RX"

Set the baseband sample rate and center frequency.

bbtx.SampleRate = 122.88e6;
bbtx.CenterFrequency = 2.2e9;

Generate random transmit waveform.

txWaveform = complex(randn(1000,1),randn(1000,1));

Transmit the generated waveform continuously with the radio associated with the baseband transmitter object using the default antenna.

transmit(bbtx,txWaveform,"continuous");

Stop the continuous transmission after 5 seconds.

pause(5);
stopTransmission(bbtx);

Configure Baseband Transceiver to Transmit and Capture Data

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

bbtrx = basebandTransceiver("MyRadio")

bbtrx = 
  basebandTransceiver with properties:

          TransmitRadioGain: 10
    TransmitCenterFrequency: 2.4000e+09
           TransmitAntennas: "RF0:TX/RX"
           CaptureRadioGain: 10
     CaptureCenterFrequency: 2.4000e+09
            CaptureAntennas: "RF0:RX2"
            CaptureDataType: "int16"
       DroppedSamplesAction: "error"
                 SampleRate: 250000000

Set the baseband sample rate.

bbtrx.SampleRate = 122.88e6;

Set the transmit and capture center frequencies.

bbtrx.TransmitCenterFrequency = 2.2e9;
bbtrx.CaptureCenterFrequency = 2.2e9;

Generate random transmit waveform.

txWaveform = complex(randn(1000,1),randn(1000,1));

Transmit the generated waveform continuously with the radio associated with the baseband transceiver object using the default transmit antenna.

transmit(bbtrx,txWaveform,"continuous");

Capture IQ data with the radio associated with the baseband transceiver object using the default capture antenna.

[data,~] = capture(bbtrx,milliseconds(3));

Stop the continuous transmission after data capture is complete.

stopTransmission(bbtrx);

Input Arguments

bba — Baseband application

basebandTransmitter object | basebandTransceiver object

Baseband application, specified as a basebandTransmitter object or basebandTransceiver object.

Note

The first object function call in which you specify this object as an input requires a few extra seconds to load the application onto the hardware.
