2.6.2
Interface functions
This instrument has the IEEE488.1 subsets about GPIB as shown in Table 2-5.
Table 2-5. GPIB interface functions
SH1
Supports all source handshake functions.
AH1
Supports all acceptor handshake functions.
T5
Specifies and cancels the talker by means of basic talker, serial poll, and MLA.
TE0
Does not support the extended talker function.
L4
Specifies and cancels the listener by means of basic listener and MTA.
LE0
Does not support the extended listener function.
SR1
Supports all the service request functions.
RL1
Supports all the remote local functions.
PP0
Does not support the parallel poll function.
DC1
Supports all instrument clear functions.
DT1
Supports all instrument trigger functions.
C0
Does not support the controller function.
E2
Uses the 3-state driver.
2.6.3
Connections
CAUTION
Before connecting or disconnecting the cables, always turn off the power to all the instruments
connected to the GPIB cable.
To operate the GPIB system, turn on all the instruments connected to the system bus.
a. Up to 15 GPIB instruments can be connected to one system.
b. The total length of the cables used to connect instruments in the system is 20m or less and 2m
(the number of instruments making up the system) or less.
c. The length of each cable used in the system is freely decided by the person in charge of
system configuration.
However, if the length of the cable connecting two instruments is 4m or more, noise margin
shall be taken into consideration.
d. A desired cable connection method (star or daisy chain, etc.) can be selected by the user.
However, use of the connection that creates the ground loop is not allowed.
e. The number of cable stacks on the connector located on the rear panel of the instrument shall
be 3 or less due to mechanical strength.
f. The connection cable applicable to the IEEE 488.1 or JIS C 1901 standard shall be used.
To improve the reliability of the system, it is recommended to use the cable, on which the EMS
measures are taken (connector with metallic housing).
g. The GPIB system needs to be operated in an electrically and mechanically good environment.
Before configuring the system, see clause 6 and appendix J of JIS C 1901-1987.
