· [OBW Off On]: Press [Measure]→ [OBW]→ [OBW Off On] to enable or
disable the occupied bandwidth measurement function.
· [Measurement Method]: Press [Measure]→ [OBW]→ [Method % XdB]
to select the appropriate test method, including percentage and drop XdB.
In the percentage method, the occupied bandwidth of the signal is obtained
by calculating the bandwidth of the frequency of certain percentage to the
total power of the transmitted power, and the power percentage can be set
by the user. In the drop XdB method, the occupied bandwidth is defined as
follows: spacing between two frequency points corresponding to signal
power drop by XdB on both sides of the frequency point where the signal
peak power is. The signal power drop XdB can be set by the user.
· [Percentage]: Press [Measure]→ [OBW]→ [%] to set the power
percentage in the percentage method.
·[XdB]
:
Press [Measure]→ [OBW]→ [XdB] to set the signal power drop
XdB in the power drop XdB method.
· [Span]: Press [Measure]→ [OBW]→ [Channel Sweep] to set the
sweeping frequency bandwidth of occupied bandwidth measurement.
