Bus Connections; Primary Address; Abbreviated Common Command Summary - Keithley 7002 Instruction Manual

SCPI (Standard Commands for Programmable Instruments)
defines a standard set of commands (and format) to control
every other aspect of instrument operation. Together, IEEE-
488.2 and SCPI create a command structure for all program-
mable instruments.
Compatibility
An instrument that uses the IEEE-488.2 standard and SCPI
does not have special hardware requirements. The IEEE-488
interface that you used with the old standard will work with
the new standard. Simply connect the Model 7002 to a com-
puter that is equipped with an IEEE-488 interface.
NOTE
The term GPIB (General Purpose Inter-
face Bus) is used in this manual and in the
menu structure of the instrument. GPIB is
simply another term for the IEEE-488 bus.

3.10.1 Bus connections

Before using the instrument over the bus, you must connect
the IEEE-488 connector on the rear panel of the instrument
to the IEEE-488 connector of your controller. Use a Keithley
Model 7007 or similar IEEE-488 cable for this connection.

3.10.2 Primary address

The primary address of the Model 7002 must agree with the
primary address you intend to specify in the controller's pro-
gramming language. The factory setting for the primary ad-
dress is 7, so if you intend to use that address, you need not
change it. However, the primary address can be set to any
value between 0 and 30 by using the GPIB setup menu (AD-
DRESS selection) available with the MENU key.
3.10.3 Abbreviated common command summary
Table 3-1 provides an abbreviated list of Common Com-
mands which are defined by the IEEE-488.2 standard. These
are the Common Commands that are most used for bus oper-
ation. Note that each Common Command is preceded by a
star (*).
Description
Clears Error Queue and event registers.
Returns the 7002 to *RST default conditions (see Table 5-5).
Issues a bus trigger (same as group execute trigger command; GET).
Saves the current setup configuration in memory (n = 0 to 9).
Returns the instrument to the setup configuration stored in memory (n = 0 to 9).
