MEAS
Press [MEAS] to access the multiple power
measurement submenu.
In spectrum analysis mode, pressing [MEAS] brings
up the menu for a suite of power measurements
such as adjacent channel power, occupied
bandwidth, channel power, spectrum monitor,
spectrum emission mask and channel scanner.
In other power measurement mode, pressing
[MEAS] brings the submenu for the current
measurement mode. Pressing [MEAS] again brings
the main menu for the power measurements
selection.
OBW
Occupied Bandwidth (OBW) integrates the power
of the spectrum in the displayed green frame. The
measurement defaults to 99% of the occupied
bandwidth power.
Occupied bandwidth measurement are made in
either single or continuous sweep mode.
Selecting a Method
Press [MEAS] > {OBW} > {Method} to toggle the
occupied bandwidth measurement mode between
percentage (%) and dBc.
• Setting Percentage (%)
Press {OBW} > {Method} > {Percent} to edit the
percentage of signal power used when determining
the occupied bandwidth. Press {%} to set the
percentage ranging from 10.00% to 99.99%.
• Setting dBc
Press {OBW} > {Method} > {dBc} to specify the power
level used to determine the emission bandwidth as
the number of dB down from the highest signal
peak, within the occupied bandwidth span. This
function is an
independent calculation from the
