The Tektronix OFDM plug-in is a simple and flexible tool to create Single or Multiple OFDM based Frames as per standards with one or more bursts in a single compile. The plug-in integrates into the SourceXpress waveform creation platform, and the AWG70000 series and AWG5200 series arbitrary waveform generators.

Key features
  • Configure and create complete multiple OFDM Frames with Preamble, Header, and Payload
  • Preset for Standard compliant Frames for various wireless standards like Wi-Fi, WiMAX
  • Define Frame with Preamble, Header, and Payload (selectively) to simulate different OFDM signals
  • Configure Symbols with Data, Pilot and Guard sub carriers with different base pattern type, amplitude profile and phase offsets
  • Subcarrier Modulation Formats including BPSK, QPSK, QAM (16, 32, 64, 256, 512, 1024), and 8-PSK
  • Add Impairments such as Phase Noise and Multipath to simulate realistic propagation scenarios
  • Define Frequency Hopping and Gated Noise to simulate practical environments for receiver testing
  • S-Parameter emulation (requires license)
    • Scattering parameters can be directly convolved with the pulse to recreate the channel characteristics
    • Cascading S-Parameters allows you to cascade up to six Touchstone files of the same format to emulate a cascaded channel
  • Offline mode
    • Designed to run on an external PC via the SourceXpress PC application, thereby reducing the time taken to synthesize large waveforms and leaving the instruments free for continued testing
  • Seamless transition between design and playback
    • The easy to use graphical user interface integrates seamlessly with the user interfaces of the SourceXpress PC application and the Tektronix AWG70000 series and AWG5200 series generators
  • Designed for integration for automated test or manufacturing
    • Programmatic Interface allows for integration into existing workflows

Complete OFDM signal definition

The OFDM plug-in allows users to configure every part of the OFDM signal definition. It allows users to build the signal symbol-by-symbol to create a complete OFDM frame. Each subcarrier in the symbol can be configured independently for Type, Modulation, and Base Data. You could then add Zero Padding or Cyclic Prefix. Symbols can be modified by specifying the clipping ratio and tone nulling. A symbol table gives you a summary of all the carriers in the selected symbol.

OFDM packets/frames can be built by specifying the spacing between the symbols/frames. Parts of the OFDM packets can be stressed by adding Gated Noise to it.
