Setting the RBW manually for the entire table
To set the resolution bandwidth manually:
1. Press the BW softkey.
2. Use the rotary control knob to highlight the desired value.
(The largest value displayed is the only largest possible value of all
channels shown.)
3. Press the OK key.
NOTE: Finer resolution normally means slower measurement speed. Regardless of
the selected value, the narrowest resolution bandwidth is limited by the
narrowest channel:
Setting the RBW separately for each channel
NOTE: Separate RBWs cannot be selected unless Others = OFF.
The value selected manually on the device applies to the entire table. You
can also enter the resolution bandwidth for each channel separately using
the PC software. Refer to the online Help function of the PC software for
information on how to do this.
Tip: More information about the RBW is found in the Glossary page 271.
12.2.5 Measuring in the gaps between defined
channels (Others)
The field strengths of the channels not selected in the multi-channel table
can be measured and their overall value shown by activating the Others
function.
NOTE: Only those other channels between the first and last channels to be
measured are taken into account.
To activate and deactivate the function:
Press the Others key until the desired status (On, Off) is displayed.
The table view shows Others; the graphical view shows O.
Tip: The measurement can be speeded up by deactivating the Others function.
