accesses the softkey menus used to load, save, and delete data from
spectrum analyzer memory.
Load
accesses a softkey menu that allows you to load a saved spectrum
analyzer state (
State
), select the trace in which trace data is to be loaded
(
Trace A B C
) and load the trace data, load the current limit line tables
(
Limits
), or load amplitude correction factors (
Ampcor
).
When loading limit line tables or amplitude-correction factors, press
Limits
or
Ampcor
, enter the trace register number, and press
Enter
. Valid
trace register numbers are 0 through the maximum register number.
The maximum register number is the number displayed during a save
or load operation. If a display title is present, it is loaded with the trace
data (but not with the limit line table or the amplitude-correction
factors). If the display title does not exceed 34 characters, the time and
date when the data was stored will also be displayed.

Save
accesses a softkey menu that allows you to store state data (
State
),
select the trace in which trace data is to be saved (
Trace A B C
) and save
the trace data, save limit line tables (
Limits
), and save
amplitude-correction factors (
Ampcor
) in spectrum analyzer memory.
Saving state data saves the spectrum analyzer settings, but not the
trace data. Saving trace data saves both the trace data and the state
data.
States and traces are retained in spectrum analyzer memory even if the
instrument is turned off or
Preset
is pressed.

New Filename
accesses a softkey menu for selecting display title
characters for the naming of files.
New Filename
does
not appear on the menu when
Internal Lock On Off
is On.
Filenames are not case-sensitive. They can be up to
eight characters long. The extensions are assigned
automatically and indicate whether the file is a trace,
state, limit line or amplitude correction factor. The
filename cannot be identical to the name of another file,
and cannot contain spaces, commas, backslashes, or
