4530 Series RF Power Meter Operation
If a precise value is required, a special digit editing mode (Figure 3-10) may be selected. This mode is entered
from increment/decrement mode by pressing the > key. When > is pressed, a digit pointer will be displayed
below the leftmost digit field, and the
∧∧∧∧∧ ∨∨∨∨
and
∨ keys will change that digit of the parameter by one count.
Pressing > or < will move the digit pointer right or left so any digit of the numeric parameter may be selected.
Pressing < when the leftmost digit is selected will return to increment/decrement mode.
Figure 3-10. Digit Editing Mode (Example)
In either editing mode, the parameter’s value is always clamped to valid limits, and cannot be advanced
beyond these limits. When editing is complete, press Enter/Run to save the new value and return to the
previous level menu. Press ESC to abort the edit and restore the original value before returning.
c. Picklist. A picklist is used to select a parameter’s value from a list of two or more fixed entries. When a picklist
is activated, the list of available values is displayed with the current value highlighted. Use the
∧∧∧∧∧ ∨∨∨∨
↓↓↓↓ ↑ ↑ ↑ ↑
and
∨ keys
to move the cursor up and down through the list until the desired value is highlighted. Press Enter/Run to
save the new value and return to the previous level menu, or press ESC to abort the edit and restore the
original value before returning. If the number of items in the picklist exceeds what can be displayed on the
screen, a
↓ or ↑ will appear to the left of the top or bottom item to indicate that there are more list items that
are scrolled off the top or bottom of the display.
d. Action Item. An action item is a menu selection that causes an event to occur or be initiated immediately when
the item is activated. In some cases (such as AutoSetup), the user will first be prompted to confirm the action
before continuing.
