Performing List Calculations
The
PreCalc List soft-key initiates a process that
examines every index in the list and performs all
the calculations necessary to set the frequency and
power levels. The soft-key does not have to be
pressed every time the list changes. The instrument
will perform the calculations to set the frequency
and power levels as it performs the initial list
sweep. This causes the initial list sweep to take
longer than each subsequent sweep. Using the
PreCalc List soft-key lets the initial list sweep be as
fast as each subsequent sweep. The calculations are
stored in volatile RAM and are lost at instrument
power-off.
Press PreCalc List to perform list calculations. The
soft-key image depresses to show that calculations
are in progress. When the calculations are com-
pleted, the soft-key returns to normal appearance.
Editing the
List List editing consists of editing list index frequency
and power level parameters and inserting and delet-
ing list index entries.
To go to the Edit List Menu (below) from the List
Sweep menu, press
