Programming Fundamentals

C Programming Using VTL

 

The following describes the parameters used above:

 

board

This optional parameter is used if you have more than

 

 

one interface of the same type. The default value for

 

 

board is 0.

 

VSI logical

 

 

address

This is the logical address of the VXI instrument.

 

primary

 

 

address

This is the primary address of the GPIB device.

 

secondary

 

 

address

This optional parameter is the secondary address of the

 

 

GPIB device. If no secondary address is specified, none

 

 

is assumed.

 

INSTR

This is an optional parameter that indicates that you

 

 

are communicating with a resource that is of type

 

 

INSTR, meaning instrument.

 

If you want to be compatible with future releases of VTL and VISA, you

NOTE

 

must include the INSTR parameter in the syntax.

 

The following are examples of valid symbolic names:

 

XI0::24::INSTR

Device at VXI logical address 24 that is of VISA type

 

 

INSTR.

 

VXI2::128

Device at VXI logical address 128, in the third VXI

 

 

system (VXI2).

 

GPIB-VXI0::24 A VXI device at logical address 24. This VXI device is

 

 

connected via a GPIB-VXI command module.

 

GPIB0::7::0

A GPIB device at primary address 7 and secondary

 

 

address 0 on the GPIB interface.

The following is an example of opening a device session with the GPIB device at primary address23.

ViSession defaultRM, vi;

.

.

viOpenDefaultRM (&defaultRM);

viOpen (defaultRM, “GPIB0::23::INSTR”, VI_NULL,VI_NULL,&vi);

.

.

viClose(vi); viClose (defaultRM);
