Tabelle 26: GPIB Interface Parameters

The remote state indication of the meter will be flashing on setting to GPIB
Talk ON. The meter auto-asserts the SRQ control line on the GPIB for
generating a new reading every 2 seconds, and reminds another GPIB device
to read the newest data. Because the function of GPIB Talk only sends
reading data to another GPIB device, the meter doesn't accept any IEEE
488.2 and SCPI commands.

7.4.1

Overview of Command Type and Formats

There are two types of the meter programming commands: IEEE 488.2 common
commands and Standard Commands for Programmable Instruments ( SCPI ).
The SCPI commands used in the meter are in conformance with the SCPI
standard Version 1993.0.

7.4.2 Common Command Format

The IEEE 488.2 standard defines the common commands as commands that
perform functions like reset, self-test and status byte query. Common
commands always come with the asterisk "*" character, and may include
parameters. Some examples of Common commands like: *IDN? , *RST ,
*CLS , *SRE?.

7.4.3 SCPI Command Format and Query Format

The SCPI commands control instrument functions. A subsystem command has a
hierarchical structure that usually consists of a top level (or root) keyword, one
or more lower level keywords, and parameters. The following example shows
a command and its associated query:
A. CONFigure:VOLTage:DC 0.12
B. CONFigure:RANGe?
