Chapter 3, Operating Overview
Using USER Keys
To Assign Global USER Keys
1. Move the cursor to the field you want to assign a global user key to.
2. Press and release the SHIFT key, then the k4 key to access the ASSIGN function. Then
press SHIFT and a global USER key (k1’ - k3’). Unlike a local user key, the user key
number does not appear at this field; instead, a prompt appears at the top of the screen
confirming the key assignment.
Example of Assigning a Global USER Key
Use this example to assign global USER key k1’ to the
AF Anl In
field, and then
access this field from the OSCILLOSCOPE screen.
1. Access the AF ANALYZER screen and position the cursor in front of the
AF Anl In
field.
2. Press and release the SHIFT key, then the k4 key to access the ASSIGN function.
3. Press SHIFT, k1’. Notice the prompt
Global User key 1 assigned.
at the top
of the screen.
4. Access the OSCILLOSCOPE screen.
5. Press SHIFT, k1’.
AF Anl Input
,
FM Demod
is displayed at the top of the screen (assuming the
present input is set to FM Demod). To change the input, use the arrow keys
(down-arrow or up-arrow), or press ENTER to access the
Choices
menu.
A field that is accessed using a global user key is only displayed at the top of the
screen while it is being accessed. Moving the cursor to any other field in the
screen causes the user key field to disappear until it is accessed again.
To Release Global USER Keys
1. Move the cursor to the field with the global user key assigned to it.
2. Press and release the SHIFT key, then the k5 key to access the RELEASE function.
Then press SHIFT and the USER key to be released (k1’-k3’).
