Keysight Technologies Making Custom OFDM Measurements Using the Keysight 89600 VSA Software with Option BHF Application Note This application note describes how to configure the Keysight Technologies Inc. 89600 VSA software with Option BHF custom OFDM modulation analysis to analyze and troubleshoot new, custom, proprietary, generic, or non- standard OFDM signals. Example files are developed and are available for further examination in the 89600 VSA software's demo signal library and Help text. The only hardware required for demonstration is a PC.
