INTRODUCTION
This guide contains two references of the GPIB
ommands listed in Appendix A of the Programmers
deference Guide included with the 2440. The first reference,
GPIB Command Reference,” sorts the commands
ccording to type: Vertical Commands, Horizontal
:ommands, etc.; the second reference, “Alphabetical GPIB
Fommand Reference,” according to the alphabetical order
f the commands. Both lists omit the descriptions for the
ommands-consult Appendix A of the Programmers
leference Guide for those descriptions.
Also included in this guide are the Event Codes and their
escriptions. These are codes which the 2440 issues over
ie GPIB that represent errors, warnings, and other
iessages of interest to System Programmers.
At the end of the guide are two charts. The first chart
hows the character set the 2440 displays. The second
hart shows ASCII symbols and their GPIB equivalents.
,ee the Programmers Reference Guide for information on
ow to use these charts.

GPIB Command Reference
GPIB Command
Reference
Throughout this Table (and the following Table), headers
md arguments are listed in a combination of bold upper
:ase and nonbold lower case letters. The instrument
accepts any abbreviated header or argument containing at
sast all the characters shown in bold upper case. Any
:haracters added to the abbreviated (upper case) version
nust be those shown in lower case. For a query, a question
nark (?) must immediately follow the header. Link
arguments shown in brackets ( [I) are defaults (don’t send
he brackets as part of the argument). In any command that
ras a default, omitting the link argument sets the default.
‘or example, ‘RUN ACQUIRE’ and ‘RUN’ are equivalent.
Some headers use numeric arguments in the ANSI
(3.42 standard format. This format states that there are
hree types of numbers; integers, reals, and reals with
exponents (these are called NRl, NR2, and NR3
espectively). Each type of number is composed of ASCII
ligits with the most significant digit sent first. Any of these
hree number types is acceptable whenever a numeric
argument is required. Here are some examples of each of
he three number types:
:NRl> 375,
:NR2> +12.589, 1.37592, - 00037.5
:NR3>
Sometimes in one of the argument columns of this table
<types> or <data src> appears and references a
ootnote at the bottom of the page. In this case, the
lrgument to use is any one of those in the referenced
ootnote.

structure of the input strings. Set CER to ON to
receive SRQ’s when any of these events occurs. If
CER is OFF, the 2440 will not assert SRQ.

System Messages
System Messages are issued to inform the controller
of bus system management events. There is no way
to mask these events except by setting RQS to OFF.
The event 459 indicates that the 2440 is currently
asserting SRQ on the bus and the controller must
read the status byte out before reading the
event code.

User Request Events
User Request events are issued when any of the
bezel buttons on the 2440 front panel are pushed.
The MENUOFF command needs to be issued before
these events will be reported. This command allows
the user to monitor front panel responses (as well as
to clear the menu for writing custom text to the
screen when desired). Set USER to ON to receive
SRQ’s when any of these events occurs. If USER is
OFF, the 2440 will not assert SRQ.
Code Description
450 Menu key #l was pushed (leftmost)
451 Menu key #2 was pushed.
452 Menu key #3 was pushed.
453 Menu key #4 was pushed.
454 Menu key #5 was pushed (rightmost).
Probe Identify Events
Probe ldentifv events are reported by the 2440 when
the probe identify feature found on certain probes is
actuated. (You can replicate this action by grounding
the outer code ring to the inner shell on the front
panel input BNC.) Set PID to ON to receive SRQ’S
when any of these events occurs. If P/D is OFF, the
2440 will not assert SRQ.

not assert SRQ.

receive SRQ’s when any of these events occurs, If
EXW is OFF, the 2440 will not assert SRQ.
