Overview
Menu fields
26
4460 GSM System Option and 4468 EDGE System Option
Version 12.20
As soon as you select a group of letters or symbols by pushing the corresponding
marker tab, the marker tabs will change again to single letters or symbols. Push
the marker tab of the desired letter or symbol. That one will appear on the entry
field and the marker tabs will change back to groups of letters and symbols.
While the entry field is open, entered values can also be edited using the
R
IGHT
function key.
Entering values on selection fields
Again, there are two ways how to work with selection fields: either you change
the selection using the 4400’s cursor keys or you simply turn the selection key.
The achievable results are basically the same.
– Select the required value using the
U
P
or
D
OWN
cursor keys.
To confirm the changes, push the
E
NTER
function key or just leave the
selection field using the
L
EFT
or
R
IGHT
cursor keys.
– Instead of selecting a new value with the cursor keys, you may also turn the
selection key.
Switching check boxes
Any push on the
E
NTER
function key toggles the currently selected check box.
This means that an unchecked check box will be switched to ‘on’ or ‘yes’ with the
first push and back to unchecked with the second push.
Unchecked boxes are indicated in gray; checked ones are highlighted in green.
Display fields
The 4400 offers you two different types of display fields:
(Alpha)numeric display fields
These kind of display fields are used to show test results as numeric values, as
strings (text) or as graphical display of numeric values (e.g. the shape of a
received burst within a template).
NOTE
When you change a parameter value on a selection field, the changes are
confirmed automatically. It is not required to push the
E
NTER
key.
