Single Channel Input and Output Operations

N200, N210, USRP2®, and B200 radios are single transceiver designs, so the default channel mapping value is read-only. B210 and X-series radios support two channels, so for SISO operation use a single channel (either channel 1 or 2).

Perform SISO Operations with SDR System Objects

The example demonstrates setting channel 2 of a B210 radio for use with an SDRu Transmitter System object™.

  1. Create an SDRu Transmitter System object.

    txradio = comm.SDRuTransmitter('Platform','B210')
    txradio = 
    
      comm.SDRuTransmitter with properties:
    
                     Platform: 'B210'
                    SerialNum: ''
               ChannelMapping: 1
              CenterFrequency: 2.4500e+09
        LocalOscillatorOffset: 0
                         Gain: 8
                    PPSSource: 'Internal'
                  ClockSource: 'Internal'
              MasterClockRate: 32000000
          InterpolationFactor: 512
            TransportDataType: 'int16'
              EnableBurstMode: false
  2. Change the channel in use by setting the ChannelMapping property.

    txradio.ChannelMapping = 2;
    txradio = 
    
      comm.SDRuTransmitter with properties:
    
                     Platform: 'B210'
                    SerialNum: ''
               ChannelMapping: 2
              CenterFrequency: 2.4500e+09
        LocalOscillatorOffset: 0
                         Gain: 8
                    PPSSource: 'Internal'
                  ClockSource: 'Internal'
              MasterClockRate: 32000000
          InterpolationFactor: 512
            TransportDataType: 'int16'
              EnableBurstMode: false

Optionally, perform the same steps with a comm.SDRuReceiver System object.

Perform SISO Operations with SDR Blocks

The example demonstrates setting channel 2 of a B210 radio for SISO operations with an SDRu Receiver block.

  1. Open the mask of an SDRu Receiver block. Set Platform to B210, X300, or X310. This example shows the mask for an SDRu Receiver block.

  2. Switch to channel 2 in SISO mode by changing the value in Channel mapping. Click OK.

Optionally, perform the same steps with the SDRu Transmitter block.
