Key Sequence: Measurements > RF Measurements
EVDO RF Measurement Menu
Channel Spectrum: Pressing this submenu key displays the channel spectrum of the input signal (2.5 MHz span). The screen also displays numeric values of Channel Power in dBm and watts, Peak to Average power in dB, and Occupied Bandwidth (Occ BW). The Ch Spectrum submenu allows OBW Span to toggle between 2.5 MHz and 1.35 MHz.
Power vs. Time: Pressing this submenu key displays a power versus time measurement. This view shows the time domain view of an EVDO half-slot. The Slot Type selection in the Setup menu determines the priority of which slot is displayed. Below the measurement display, numerical values are included for:
Pilot and Mac Power in dBm
Freq Error in Hz and PPM
Channel Power in dBm
ON/OFF Ratio: Power ratio (in dB) of Pilot and MAC power to the data power in an idle slot
Idle Activity: Percentage of idle slots relative to total slots in the captured signal
ACPR: Pressing this submenu key displays the Adjacent Channel Power Ratio (ACPR). The instrument displays one or more main channels and two adjacent channels on each side of the main channel. A data window below the channel measurement display indicates the power in each channel. When this submenu key is active (an arrow on the key symbol indicates that a sub menu is available), another key press opens the ACPR Menu.
Spurious Emission: Pressing this submenu key displays the received signal and the mask, based upon received signal strength.
RF Summary: Displays a summary table of all the RF numerical measurement results.
Back: Returns to the Measurements Menu.
