Configures properties of the transmit (Tx) or receive (Rx) signal.

Note The USRP devices are not calibrated. The gain value does not represent an absolute gain and does not have linear behavior. Different devices exhibit different gain curves for different carrier frequencies. You may need to experiment to determine the correct gain setting for your application.

Inputs/Outputs

  • cstr.png channel list —

    channel list specifies the channel(s) to configure.

  • civrn.png session handle —

    session handle identifies your instrument session.

    session handle is obtained from the niUSRP Open Tx Session VI or the niUSRP Open Rx Session VI and identifies a particular transmit (Tx) or receive (Rx) session.

  • cdbl.png IQ rate —

    IQ rate specifies the rate of the baseband I/Q data in samples per second (S/s).

  • cdbl.png carrier frequency —

    carrier frequency specifies the carrier frequency, in Hz, of the RF signal.

  • cdbl.png gain —

    gain specifies the aggregate gain, in dB, applied to the RF signal.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • cstr.png active antenna —

    active antenna specifies the antenna port to use for this channel.

    Refer to the antenna names topic for your device for a list of antenna names that active antenna accepts.

  • iivrn.png session handle out —

    session handle out passes a reference to your instrument session to the next VI.

    session handle out is obtained from the niUSRP Open Tx Session VI or the niUSRP Open Rx Session VI and identifies a particular transmit (Tx) or receive (Rx) session.

  • idbl.png coerced IQ rate —

    coerced IQ rate returns the actual I/Q rate, in samples per second (S/s), for this session, coerced to a value supported by the device.

  • idbl.png coerced carrier frequency —

    coerced carrier frequency returns the actual carrier frequency, in Hz, for this session, coerced to a value supported by the device.

  • idbl.png coerced gain —

    coerced gain returns the actual gain, in dB, for this session, coerced to a value supported by the device.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
