The BEGIN gives you the capability to the key
menu and user-defined macro functions. The key is only
available if your analyzer has (Option installed. Use this key to
define macros such as:
l
to implement save/recall
l
to implement most used functions or features
l
to implement often-used features that involve a number of steps
Macros must be within an program. If no BEGIN

analyzer will automatically create a default program.
BEGIN
OFF selects the key menu to mode when
ON, and to normal operation when OFF.
Once you have changed the mode to ON, the same menu will
be displayed for subsequent key presses of the (This is not
true if your program has changed. If the program has changed, the
mode is reset to OFF.)
Use of the User BEGIN function does not restrict access to any normally
available instrument feature such as marker functions, etc., nor does this key
affect sweep update rates.
Refer to example programs provided on the programs disk for
implementation requirements. Keystroke recording may be used to modify or
update
programs.
