Fixed WiMAX RF Measurements and Fixed WiMAX Demodulator Measurements. These instruments can measure both FDD and TDD networks. They can measure Fixed WiMAX BTS transmitter performance over the air by connecting an antenna or by connecting the BTS equipment directly to the instrument. To connect the BTS equipment directly to the instrument, connect the power amplifier of the BTS equipment to the RF In connector of the instrument by using a coupler or attenuator. To measure a Fixed WiMAX signal over the air, connect the appropriate frequency band antenna to the instrument RF In connector.
Mobile WiMAX Over‑the‑Air (OTA) Measurements (Option 37)
Over‑the‑Air (OTA), RF, and Demodulator Measurements. OTA Measurements require that an antenna be attached to the Spectrum Analyzer RF In (50 Ohm) connector on the instrument. Attach a coupler or attenuator to the same connector to make measurements directly from the WiMAX BTS transmitter.
