Front panel softkeys
Make your own front panel functions by defining softkeys, up to 58 characters
in length, directly from the front panel. Any analyzer command can be put
into a softkey, including program flow commands such as REPEAT and UNTIL,
and new firmware commands such as PEAKS. You can even define a softkey
that will execute other softkeys. Measurements that require several front
panel functions can be incorporated into one softkey to save time and
simplify measurements.
How to define measurement routines from the front panel
These four steps illustrate how easy it is to define a softkey that finds the
highest signal in a given span and “auto zooms” to a span of 100 kHz.
1. Select the commands
Use the GP-IB commands that are
necessary to accomplish this task;
in this case, MKPK HI (Peak Search),
MKTRACK ON (Signal Track On),
SP100KZ (Set Frequency Span to
100 kHz), TS (Take Sweep), and
MKRL (Bring the Signal to the
Reference Level).

2. “Type”commands into the
title block
To put the group of commands in a
softkey, “type” them into the title
block of the CRT. To do this, press
[SHIFT] E[AUTO]. This puts the
analyzer in the title mode so when
you press a front panel key, the letter
above the key appears in the upper
left corner of the CRT. Type in MKPK
HI,MKTRACKON,SP100KZ,TS,MKRL.
Press [NORMAL] (next to [SHIFT])
to terminate the title mode.
3. Store commands in RAM
To enter the commands in a softkey,
press [SHIFT] [2] [6] [kHz]. This
stores the commands in the RAM
of the analyzer under softkey 26.
(Softkeys can be labeled with any
number from 1 to 999.) Note: If “Save
Lock” appears in the active function
block on the center of the CRT, press
[SHIFT] [RECALL] and repeat the
key sequence [SHIFT] [2] [6] [kHz].
(Save Lock is a memory protection
function. For more information on
this feature, refer to page 8.)
4. Execute the softkey
Now you have a new front panel
function on the analyzer that
“autozooms” on a signal. This
measurement used to require eight
front panel keystrokes; now they
are all in one softkey. To execute it,
press [SHIFT] [2] [6] [HZ]. Notice
that “Softkey 26” appears in the
active function block of the CRT.
You can also define measurement
routines via GP-IB using a computer.
A computer provides the keyboard,
editing. and formatting capabilities
not available on the front panel of
the analyzer. This makes it possible
to enter into the analyzer softkey
routines greater than 58 characters
in length. This method is discussed
in more detail on page 13.
