    ® Configuration R&S FSV3-K106 Configuration overview 4 Configuration LTE NB-IoT measurements require a special application on the R&S FSV/A, which you can select by adding a new measurement channel or replacing an existing one. When you start the LTE NB-IoT application, the R&S FSV/A starts to measure the input signal with the default configuration or the configuration of the last measurement (if you haven't performed a preset since then).
  • Page 35 ® Configuration R&S FSV3-K106 Configuration overview In addition to the main measurement settings, the "Overview" provides quick access to the main settings dialog boxes. The individual configuration steps are displayed in the order of the data flow.

    ® Remote control R&S FSV3-K106 Configuration [SENSe:]ADJust:LEVel<ant> Initiates a single (internal) measurement that evaluates and sets the ideal reference level for the current input data and measurement settings. This ensures that the set- tings of the RF attenuation and the reference level are optimally adjusted to the signal level without overloading the R&S FSV/A or limiting the dynamic range by an S/N ratio that is too small.

    ® Performing time alignment measurements R&S FSV3-K106 Annex A Performing time alignment measurements The measurement application allows you to perform time alignment measurements between different antennas. The measurement supports setups of up to two Tx antennas. The result of the measurement is the time alignment error. The time alignment error is the time offset between a reference antenna (for example antenna 1) and another antenna.
