TD‑LTE RF Menu
Channel Spectrum: Opens the Channel Spectrum Menu. Displays the spectrum of the input signal. Beneath the graph, values for the following measurements are displayed: Channel Power and Occupied BW. Channel Power is displayed in dBm or Watts (based on the Units submenu setting in the Amplitude menu) and Occupied BW is displayed in MHz. Press this button again to list the Channel Spectrum menu to set the Span.
Power vs. Time: Opens the Power vs. Time Menu.
Displays the Power vs. Time graph showing the signal in the time domain.
ACLR: Displays a bar graph of the main channel power and two adjacent channels on either side. The table underneath the chart lists the frequency, power, and power relative to the main channel (in dB).
Spectral Emission Mask: Opens the Spectral Emission Menu. The Spectral Emission Mask measurement supports the testing for “Operating Band Unwanted Emissions” described in the 3GPP TS 36.141 Base Station Conformance testing document. There is support for Category A and Category B (Option 1 only) masks which are automatically selected based on the current carrier frequency/channel and BW values.
The instrument indicates if 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 and whether the signal PASSED/FAILED in that region. Press this button again to list the Spectral Emission submenu.
