Keithley 7001 User Manual

Getting Started

3.7.1 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 control-
ler. Use a Keithley Model 7007 or similar IEEE-488 ca-
ble for this connection.
3.7.2 Primary address
The primary address of the Model 7001 must agree
with the primary address you intend to specify in the
controller’s programming language. The factory set-
ting for the primary address is 7, so if you intend to use
that address, you need not change it. However, the pri-
mary address can be set to any value between 0 and 30
by using the GPIB setup menu (ADDRESS selection)
available with the MENU key.
Table 3-1
Abbreviated common command summary
Mnemonic Name Description
*CLS Clear status Clears Error Queue and event registers.
*RST Reset Returns the 7001 to *RST default conditions (see Table 5-6).
*TRG Trigger Issues a bus trigger (same as group execute trigger command; GET).
*SAV <n> Save Saves the current setup configuration in memory (n = 0 to 9).
*RCL <n> Recall Returns the instrument to the setup configuration stored in memory
(n = 0 to 9).
3.7.3 Abbreviated common command sum-
mary
Table 3-1 provides an abbreviated list of Common
Commands which are defined by the IEEE-488.2 stan-
dard. These are the Common Commands that are most
used for bus operation. Note that each Common Com-
mand is preceded by a star (*).
3.7.4 Abbreviated SCPI command summary
Most instrument operations are controlled using SCPI
commands. Table 3-2 provides an abbreviated list of
the SCPI commands necessary to perform some basic
operations.
Not shown in the table are companion query com-
mands for the :ARM and :TRIGger Subsystem com-
mands (:COUNt?, :DELay?, :SOURce?, and :TIMer?).
For example, the :TRIGger:SOURce? query command
is used to request the currently selected control source.
After the query command is sent and the Model 7001 is
addressed to talk, a message identifying the selected
control source will be sent to the computer.
