The Power versus Time view shows the time domain view of a Mobile WiMAX signal over approximately one frame. The screen also displays Channel Power (RSSI), Downlink Burst Power, Uplink Burst Power, and Preamble Power. The sample image in Figure: Mobile WiMAX Power versus Time Measurement may differ from any image on your instrument.

Press the Power vs Time submenu key to select the measurement.

The Spectral Emission Mask (SEM) measurement supports the testing for Operating Band Unwanted Emissions described in the 802.16 testing document. The instrument displays the frequency masks on the spectrum display, and it indicates the reference power and whether the signal is within the specified limits by displaying PASS or FAIL. The emission mask information is also displayed in a table format with different frequency ranges, power levels, and measured bandwidth and whether the signal PASSED or FAILED in that region.
