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.
Spurious Emission: Pressing this submenu key displays the received
signal and the mask, based upon received signal strength.
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” on
page 2-25 .
RF Summary: Displays a summary table of all the RF numerical

frequency. The submenu key menu displays units of GHz, MHz, kHz, and
Hz. After choosing the units, press the
Enter key. If the Enter key is used
without first selecting units, then the default units are MHz, and the Enter
key must be pressed a second time to set the frequency. You can also use
the arrow keys or rotary knob to change the carrier bandwidth in 1 Hz
increments, then press the rotary knob or the
Enter key to set the frequency.
