 | BW Opens the Select Bandwidth list box. Use the Up/Down arrow keys or the rotary knob, and then press the Enter key. The following three bandwidths are available: 3.5 MHz, 5 MHz, 7 MHz, 8.75 MHz, and 10 MHz. The default bandwidth is 5 MHz. CP Ratio (G) The CP Ratio is fixed at 1/8 for Mobile WiMAX. You cannot change this parameter. Span Press this submenu key to open the Span list box and select the desired span for the Spectrum view. Use the Up/Down arrow keys or the rotary knob, and then press the Enter key. The available span selections are: 5 MHz, 10 MHz, 20 MHz, and 30 MHz. Note: The span value is automatically adjusted to the next largest available span when the bandwidth setting is changed. The span can be changed to any of the available values in order to override the automatic selection. Frame Length Toggles between 5 ms and 10 ms for the desired frame length. Demod Toggles through the available selections for Automatic, Manual, and Frame Control Header (Auto, Man, FCH). When Auto is chosen, the instrument attempts to demodulate the signal, decode the DL‑MAP, and use that information to demodulate the data portion of the frame. When Manual is chosen, a parameter file must be available (you must have already loaded this parameter file). The parameters from this file are used by the instrument to demodulate the data bursts. Note: The Manual mode setting is not saved in setup files, nor is it saved when power is turned off. If Demod is set to Manual mode before the instrument is turned off, then the Demod setting becomes Auto mode when the instrument is turned on. When FCH is chosen, only the FCH portion of the signal is demodulated. Load Param File Press this submenu key to open the Parameter Files (XML) list box and to select the parameters that are stored in an XML file. This file needs to be generated by using the Anritsu IQProducer software. More Options Press this submenu key to open the Setup (2) Menu, to view the menu description. |
