Before Using the GPIB Examples
HP Basic addresses the signal generator at 719. The GPIB card is addressed at
7 and the signal generator at 19. The GPIB address designator for other
libraries is typically GPIB0 or GPIB1.
GPIB Function Statements (Command Messages)
Function statements are the basis for GPIB programming and instrument
control. These function statements, combined with SCPI, provide management
and data communication for the GPIB interface and the signal generator.
This section describes functions used by different IO libraries. For more
information, refer to the NI-488.2 Function Reference Manual for Windows,
Keysight Standard Instrument Control Library reference manual, and Microsoft
Visual C++ 6.0 documentation.
Abort Function
The HP Basic function
ABORT
and the other listed IO library functions terminate
listener/talker activity on the GPIB and prepare the signal generator to receive
a new command from the computer. Typically, this is an initialization command
used to place the GPIB in a known starting condition.
Library Function Statement Initialization Command
HP Basic The
ABORT
function stops all GPIB activity.
