R&S®FSQ-K92 Application Firmware

TX measurements on OFDM signals in line with IEEE 802.16-2004

Applications

The R&S®FSQ-K92 application firmware allows the analysis of WiMAX™ signals in line with the IEEE 802.16‑2004 standard

The option offers a wide range of possible settings so that the user can optimally adapt the measurement to the signal to be analyzed. In addition to frequency, bandwidth, and sample rate, the guard interval length of the WiMAX™ signal can be defined. A wide range of other parameters such as memory depth or trigger settings can be adapted as needed. The main parameters and results of the measurements are listed in a numeric table:

  • EVM results (averaged)
    • EVM (all carriers)
    • EVM (data carriers only)
    • EVM (pilot carriers only)
  • I/Q constellation
    • I/Q offset
    • Gain imbalance
    • Quadrature offset
  • Power measurement
    • In time and frequency domain
    • Crest factor
    • Radio signal strength indicator (RSSI) measurement
  • Carrier frequency error and symbol clock error
  • Carrier to interference and noise ratio (CINR) measurement
    • WiMAX™ signals detected within the period of recording" onclick="dcsMultiTrack('WT.pi', 'Brand.InfoLayerOpen');">Screen of R&S®FSQ-K92

    The result summary displays the most important parameters for characterizing WiMAX™ signals detected within the period of recording
