Multimeter Command Reference

This chapter describes the Standard Commands for Programmable Instruments
(SCPI) and IEEE 488.2 Common (*) Commands applicable to the HP E1312A and
HP E1412A 6½-Digit Multimeters.
Commands are separated into two types: IEEE 488.2 Common Commands and SCPI
Commands.
The IEEE 488.2 standard defines the Common commands that perform functions like
reset, self-test, status byte query, etc. Common commands are four or five characters
in length, always begin with the asterisk character (*), and may include one or more
parameters. The command keyword is separated from the first parameter by a space
character. Some examples of common commands are shown below:
*RST
The SCPI commands perform functions such as making measurements, querying
instrument states, or retrieving data. The SCPI commands are grouped into command
"subsystem structures". A command subsystem structure is a hierarchical structure
that usually consists of a top level (or root) command, one or more low-level
commands, and their parameters. The following example shows the root command
CALibration and its lower-level subsystem commands:
CALibration
:COUNt?
:LFRequency 50|60|MIN|MAX
:LFRequency? [MIN|MAX]
:SECure:CODE <
:SECure:STATe OFF|ON, <
:SECure:STATe?
quoted string
:STRing <
:STRing?
:VALue < value >
:VALue?
:ZERO:AUTO ON|OFF
:ZERO:AUTO?
is the root command,
CALibration
, ,
STRing STRing? VALue
STATe and STATe? are third level commands.
