Gpib Interface - TTI PL-P Serie Manuel D'utilisation

GPIB Interface

The 24-way GPIB connector is located on the instrument rear panel.
The pin connections are as specified in IEEE Std. 488.1-1987 and the instruments in the range
comply with IEEE Std. 488.1-1987 and IEEE Std. 488.2-1987 and contain the following IEEE
488.1 subsets.
GPIB Subsets
This instrument contains the following IEEE 488.1 subsets:
Source Handshake
Acceptor Handshake AH1
Talker
Listener
Service Request
Remote Local
Parallel Poll
Device Clear
Device Trigger
Controller
Electrical
Interface
* Although no Device Trigger capability is included, the GET message will not cause a
command error unless its position in the input stream dictates that it should; e.g. buried
inside a <PROGRAM MESSAGE UNIT>.

GPIB Parallel Poll
The power supplies offer complete parallel poll capabilities. The Parallel Poll Enable Register is
