Anritsu handheld instruments offer Mobile WiMAX Over‑the‑Air (OTA) measurements, RF measurements, 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.
Caution
The maximum (without damage) input level of the RF In port is + 30 dBm. To prevent damage, always use a coupler or a high power attenuator.
