Introduction
Interface Functions
between decimal 0 and 30. This instrument address is used by the computer to direct com-
mands and communications to the proper instrument on an interface. The default is typically
“7” for this instrument. You can change the instrument address in the Utilities, Remote Inter-
face dialog box.
N O T E Do Not Use Address 21 for an Instrument Address. Address 21 is usually reserved for the Computer interface
Talk/Listen address and should not be used as an instrument address.
Bus Commands
The following commands are IEEE 488.1 bus commands (ATN true). IEEE 488.2 defines
many of the actions that are taken when these commands are received by the instrument.
The device clear (DCL) and selected device clear (SDC) commands clear the input buffer
and output queue, reset the parser, and clear any pending commands. If either of these com-
mands is sent during a digitize operation, the digitize operation is aborted. The group execute
trigger (GET) command arms the trigger. This is the same action produced by sending the
RUN command. The interface clear (IFC) command halts all bus activity. This includes unad-
dressing all listeners and the talker, disabling serial poll on all devices, and returning control
to the system computer.
