Table 4A-2. IEEE 488.2 Interface Functions from the SCPI Command Set
Description Code Description
Instrument
Handshake
SH1
The Instrument can exchange data with other instruments or a
controller using the bus handshake lines: DAV, NRFD, and NADC.
Acceptor
Handshake
AH1
The Instrument can exchange data with other instruments or a
controller using the bus handshake lines: DAV, NRFD, and NADC.
Control Function
C0
The Instrument does not function as a controller.
Talker Function
T6
The Instrument can send responses and the results of its settings to
other devices or to the controller. T6 means that it has the following
functions:
•
Basic talker.
•
No talker only.
•
It can send out a status byte as response to a serial poll from the
controller.
Automatic un-addressing as a talker when it is addressed as a listener.
Listener Function
L4
The Instrument can receive programming instructions from the
controller. L4 means that it has the following functions:
•
Basic listener.
•
No listen only.
•
Automatic un-addressing as listener when addressed as a talker.
Service Request
SR1
The Instrument can call for attention from the controller, e.g., when a
response is available or an error has occurred.
Remote/Local
Function
RL1
You can control the Instrument manually (locally) from the front panel
or remotely from the controller. The LLO, local-lock-out function, can
disable the LOCAL button on the front panel.
Parallel Poll
PP0
The Instrument does not have any parallel poll facility.
Device Clear
Function
DC1
The controller can reset the Instrument via interface message DCL
(Device clear) or SDC (Selective Device Clear).
Device Trigger
Function
DT0
The Instrument does not support GET (Group Execute Trigger).
Bus Drivers
E2
The GPIB interface has tri-state bus drivers.
