IM 760301-17E
The GP-IB interface of the instrument conforms to the IEEE 488.2-1992 Standard. This
standard specifies that the following 23 points be stated in the document. This section
describes these points.
(1)
Of the IEEE 488.1 interface functions, the subsets that are supported
See section 1.3, "GP-IB Interface Specifications."
(2)
The operation of the device when it is assigned an address outside the 0 to 30
range
The address of this instrument cannot be set to an address outside the 0 to 30
range.
(3)
Reaction of the device when the user changes the address
The address change occurs when the address is specified using the MISC key
menu. The new address is valid until the next time it is changed.
(4)
Device settings at power-up. The commands that can be used at power-up.
Basically, the previous settings (i.e. the settings which were valid when power
was turned OFF) are valid.
All commands can be used at power-up.
(5)
Message exchange options
a) Input buffer size
1024 bytes
b) Queries that return multiple response units
See the example of the commands given in chapter 6.
c) Queries that create response data when the command syntax is being
analyzed
All queries create response data when the command syntax is analyzed.
d) Queries that create response data during reception
There are no queries of which the response data are created upon receiving

See the example of the commands given in chapter 6.
(6)
Items that are included in the functional or composite header elements
constituting a command
See chapter 5 and 6.
(7)
Buffer sizes that affect block data transmission
During block data transmission, the output queue is expanded according to the
size.
