Safety Notices

CAUTION

A CAUTION notice denotes a

hazard. It calls attention to an

operating procedure, practice, or

the like that, if not correctly

performed or adhered to, could

result in damage to the product or

loss of important data. Do not

proceed beyond a CAUTION notice

until the indicated conditions are

fully understood and met.

WARNING

A WARNING notice denotes a

hazard. It calls attention to an

operating procedure, practice, or

the like that, if not correctly

performed or adhered to, could

result in personal injury or

death. Do not proceed beyond a

WARNING notice until the

indicated conditions are fully

understood and met.

The Multimeter Language

The multimeter uses a language developed

around a core set of commands which can in

themselves satisfy a large number of applications.

The core commands consist of 8 commands plus

the measurement function commands (FUNC,

ACV, DCL etc.). All recent Keysight multimeters

support these 8 commands plus the function

commands that correspond to the capabilities of

the multimeter. The 8 commands are:

The complete command set extends the

multimeter’s capabilities far beyond that of the

above core commands. If compatibility with other

Keysight multimeters is critical for your

applications, you should strive to use only the

core commands and the GPIB commands.

RESET Sets the multimeter to the power-on state

PRESET Sets the multimeter to a convenient starting

point for remote operation

ID? Returns the multimeter's model number

TEST Runs self-test

ERR? Reads the error register

STB? Reads the status register

TRIG Selects the trigger event

NPLC Selects the integration time

Syntax Rules

6 Keysight 3458A Quick Reference Guide

Syntax Rules

– Command headers may be entered in upper

or lower case.

– Parameters may be entered in upper case,

lower case, or as a numeric value. Numeric

values can be either integer, floating-point, or

exponential in format. Parameters in

floating-point format are rounded to the

nearest integer if the command requires an

integer. For example, “SUB 2.49” is rounded

down to “SUB 2" and “SUB 2.5” is rounded up

to “SUB 3”.

– Command headers and parameters must be

separated by either a space or a comma.

– You can default a parameter by omitting it or

replacing it with -1 (minus 1). From remote

only, you can use two commas to indicate a

default value.

– The carriage return (cr), line feed (lf),

semicolon (;), or EOI sent concurrent with the

last character indicate the end of message

(command terminator) to the multimeter.

When you send a command from the system

controller in the standard format (e.g.

OUTPUT 722:“TEST”), the controller typically

adds a cr lf to the end of the command. With

its input buffer off (off is the power-on input

buffer mode), the multimeter processes the cr

immediately, but does not process the lf until

the command completes execution. This

means that, because of the lf, the bus is held

and you cannot regain use of the controller

until the multimeter is done executing the

Syntax Rules

Keysight 3458A Quick Reference Guide 7

command (or the GPIB CLEAR command is

executed which aborts execution of the

command).

You can prevent the bus from being held by

suppressing the cr lf when sending

commands or by enabling the input buffer

(INBUF ON command). The following program

line shows how to use the # and K image

specifiers to suppress cr If when sending a

multimeter command.

OUTPUT 722 USING “#,K”;“TEST;”

The # and K image specifiers apply to HP

Series 200/300 computers. Refer to your

computer’s operating manual for information

on how your computer suppresses cr lf. The

semicolon following the TEST command

indicates the end of the command to the

multimeter and must be present when you

suppress cr lf.

– Multiple commands, separated by

semicolons. may be sent in one command

string. For example, the following command

string contains 3 multimeter commands.

OUTPUT 722;“TRIG HOLD;DCV 3;NPLC 1”
