GPIB address

The controller addresses the instrument with the GPIB bus channel, see Chapter 9.2.1,

"Interface settings", on page 117. GPIB provides channel addresses from 0 to 30. The

GPIB address is preset to 20 (factory-set), but you can adjust it according to your net-

work environment, see "Assigning the GPIB address manually" on page 163. An instru-

ment preset does not affect the GPIB address.

The GPIB resource string syntax is as follows:

GPIB:://<channel>[::INSTR]

GPIB

= denotes the used interface

<channel address> = the used channel

[::INSTR] = indicates the instrument resource class (optional)

Note: If the VISA implementation supports the GPIB interface, you can optionally

define the VISA Instrument Control Resource (INSTR). It is used to define the basic

operations and attributes for a device, such as reading, writing, or triggering.

Example:

GPIB::28

28 is the selected GPIB bus channel

10.2.4 Status reporting system

The status reporting system saves all information on the current operating state of the

instrument and errors which have occurred. This information is saved in the status reg-

isters and in the error queue. You can query the status of the registers remotely, i.e.

over the USB, GPIB or LAN interfaces with the commands of the Chapter 11.14, "STA-

Tus subsystem", on page 208.
