Result Length (802.16 OFDM)

Default: See 802.16 OFDM Standard Setups/Presets Table.

Result Length parameters specify how much data is acquired and demodulated. There are three selections for determining the Result Length.

Automatic: the result length is set to the smaller of Max Result Length and number of symbol-times detected within the burst.
From FCH (Frame Control Header): The VSA uses the frame control header to determine the measurement result length. If the FCH symbol is not present, the measurement result length is auto-detected based on the RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). pulse length. In either case, the result length is limited by the Max Result Length setting.
Manual: The VSA uses the value entered in the Manual Override text box as the measurement result length and ignores the number of symbol-times detected within the burst.

The Measurement Interval and Measurement Offset parameters are used to specify the measurement length within the Result Length.

Result length also determines the maximum number of symbols that the VSA displays. For example, if the result length is set to 10, the VSA displays 10 symbols in the time-domain traces (such as vector, eye, and constellation diagrams).
