Appendix 3 Overview of IEEE 488.2-1987
The GP-IB interface provided with WT1600 conforms to IEEE 488.2-1987. This standard requires the following 23
points be stated in this document. This Appendix describes these points.
1
Subsets supported by IEEE 488.1 interface functions
Refer to Section 1.4 “GP-IB Interface Specifications”.
2
Operation of device when the device is assigned to an address other than addresses 0 to 30.
The WT1600 does not allow assignment to an address other than 0 to 30.
3
Reaction when the user changes the address
The current address is changed when a new address is set using the MISC key. The
newly set address is valid until another new address is set.
4
Device set-up at power ON. Commands which can be used at power ON
Basically, the previous settings (i.e. the settings which were valid when power was
turned OFF) are valid. All commands are available at power ON.
5
Message transmission options
a
Input buffer size
1024 bytes
b
Queries which return multiple response messages
Refer to Chapter 5, “Command List”.
c
Queries which generate response data during analysis of the syntax
Every query generates a response data when analysis of the syntax is completed.
d
Queries which generate response data during reception
No query generates response data when the query is received by the controller.
e
Commands consisting of parameters which restrict one other
Refer to Chapter 5, “Command List”.
6
Options included in command function elements and composite header elements
Refer to Chapters 4 and 5.
7
Buffer size which affects transmission of block data
During transmission of block data, the output queue is extended according to the size of
the data blocks.
8
List of program data elements which can be used in equations, and nesting limit
No equations can be used.
9
Syntax of response to queries
Refer to the description of the commands given in Chapter 5.
10 Communications between devices which do not follow the response syntax
No communications between devices.
