Specifications

limited to approximately 500 statements. A statement consists of a
keyword (such as, SAVE AUTOCAL), or a keyword and a value (such
as, START 1.2 GHz), and each statement represents the set of
keystrokes required to perform the statement function. The effective
size of a sequence can be increased by cascading multiple sequences.
A-3 BASIC FUNCTIONS Basic functions are described in Table A-1.
A-4 CONTROL STATEMENT A set of control conditions provides the capability to modify the
sequence of executed statements based on a set of realtime conditions.
Control Statement capabilities are described in Table A-2 (page A-5).
A-5 KEYS OPERATE
DIFFERENTLY
Some keys on the front panel operate differently during editing or
executing a sequence. During editing, the Clear/Local key deletes a
statement in a sequence, and the rotary knob moves the editing cursor
to a different statement. When a sequence is executing, all keys are
disabled except the Enter and Clear/Local keys. The Clear /Local key
terminates executions; the Enter key releases a pause.
A-6 CONVENTIONS Refer to Chapter 1, paragraph 1-13, for an explanation of the
typographic conventions used to document the procedures.

A-4 MS462XX OM
Function Description
Create Uses the EDIT SEQUENCE soft key function to create a new sequence. After a sequence is selected, all
subsequent keystrokes are recorded and placed in the selected sequence memory area.
Save Uses the DONE SEQUENCE soft key function. The current sequence recording is terminated and saved
in a designated memory area. Using the SAVE SEQUENCE function under the Sequence utility, a
sequence can be saved on a floppy disk or on the hard disk.
Display During a sequence edit, the content of the sequence is displayed on the screen. Display of menu
transitions may be enabled and disabled by the user. The display window is 30 character wide and 11
lines long. The last line of the display window is to display the availability of characters.
Execute After a sequence is selected for execution, that sequence is executed automatically. Also supported over
the GPIB.
Modify The modify function works as follows:
To delete a statement: Move the cursor to the statement and press the clear key.
To insert a statement: Move the cursor to the line above the new statement and insert the new statement.
To add a statement: Move the cursor to the last statement in the sequence and enter the new statement.
