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. 10 ABORT 7
VISA Library In VISA, the viTerminate command requests a VISA session
to terminate normal execution of an asynchronous operation.
The parameter list describes the session and job id.
viTerminate (parameter list)
NI- 488.2 The NI- 488.2 library function aborts any asynchronous read,
write, or command operation that is in progress. The
parameter ud is the interface or device descriptor.
