19.3 Occupied Bandwidth Measurement <OBW>
It is possible to measure the occupied frequency bandwidth defined as the width of points at N(%) of the total
power (N% POWER), or as the width of points that are X(dB) lower than the peak level (XdB DOWN).
• N% POWER mode [ By pushing (MODE), N% POWER mode (N%) is selected.]
The bandwidth of points at N(%) of the total power is measured.
• XdB DOWN mode [ By pushing (MODE), XdB DOWN mode (X dB) is selected.]
The bandwidth of points that are X(dB) lower than the peak level is measured.
19.4 Electric Field Strength Measurement <E/F ANT>
Connecting a dipole antenna (option) to the RF input enables the measurement of the electric field strength.
Other than the optional antenna is also available by creating the original compensation data.
(Refer to “25.8 Writing of Original Compensation Data” for the details.)

* “OBW XdB” is displayed in MEAS area on the screen.
* The measured value is displayed at the lower right corner on the screen.
1. By (XdB) , the down level from
the peak level is set.
* Setting range : 0.1 to 99.0dB
2. By , the step size of XdB can be set to 1dB or 0.1dB.
* “OBW N%” is displayed in MEAS area on the screen.
* The measured value is displayed at the lower right corner on the screen.
1. By (RATIO %) , the percentage of the
total power is set.
* Setting range : 80.0 to 99.9%
2. By , the step size of RATIO % can be set to 1% or 0.1%.
