Appendix 2.1 Overview of IEEE 488.2-1987
The GP-IB interface provided with this instrument 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 the specifications on page 11-1.
(2) Operation of device when the device is assigned
to an address other than one of the addresses 0
to 30
This instrument does not allow assignment to an address
other than 0 to 30.
(3) Reaction when the user initializes address
settings.
Change of the current address is acknowledged when a
new address is set using the INTERFACE key menu. 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 and operation
The input buffer's capacity is 1024 bytes.
(b) Types of queries which return multiple
response messages
Refer to the examples of each command in Appendix
2.3.
(c) Types of queries which generate response
data during analysis of the syntax
Every query generates response data when analysis of
the syntax is performed.
(d) Types of queries which generate response
data during reception
No query generates response data when it is received
by the controller.
(e) Types of commands which have pairs of
parameters.
No such commands.
(6) List of function elements which configure
commands used for the device. All those which
are included in elements of composite command
program headers
Refer to Appendix 2.2 and 2.3.
(7) Buffer size which affects transmission of block
data
Block data are not supported.
(8) List of program data elements which can be
used in equations and nesting limit
Cannot be used.
(9) Syntax of response data to queries
Refer to the examples of each command in Appendix 2.3.
(10) Communication between devices which do not
follow the rules regarding response data
No other modes than conforming to IEEE 488.2-1987 are
supported.

Appendix 2.1 Overview of IEEE 488.2-1987
(11) Size of data block of response data
Block data are not supported.
(12) List of supported common commands
Refer to Appendix 2.3.15 Common Command Group.
(13) Condition of device when calibration is
successfully completed
*CAL? is not supported.
(14) Maximum length of block data which can be
used for definition of trigger macro when *DDT
is used
*DDT is not supported.
(15) Maximum length of macro label if macro
definition is used; maximum length of block data
which can be used for definition of macro;
processing when recursion is used in definition
of macro
Macro functions are not supported.
(16) Response to *IDN?
Refer to Appendix 2.3.15 Common Command Group.
(17) Size of storage area for protected user data if
PUD and *PUD? are used.
*PUD and *PUD? are not supported.
(18) Length of resource name if *RDT and *RDT? are
used.
*RDT and *RDT? are not supported.
(19) Change in status if *RST, *LRN?, *RCL and *SAV are
used.
*RST
Refer to Appendix 2.3.15 Common Command Group.
*LRN?, *RCL, *SAV
These commands are not supported.
(20) Execution range of self-test using *TST?
Refer to Appendix 2.3.15 Common Command Group.
(21) Structure of extended return status
Refer to Appendix 2.4.
(22) To find out whether each command is performed
in parallel or sequentially
Refer to Appendix 2.2.6 Synchronization with the
Controller, or Appendix 2.3.
(23) Functions performed until a message indicating
completion of the command is displayed
Refer to the function description of each command in
Appendix 2.3, and to the corresponding chapters.
