Appendix 3 Overview of IEEE.488.2-
1992
The GP-IB interface provided with the TA720 conforms
to the IEEE 488.3-1992 Standard. This standard
specifies that the following 23 points be stated in the
document. This section describes these points.
1 Subsets supported by IEEE 488.1 interface
functions
See "GP-IB Interface Specifications" on page 1-3.
2 Operation of device when the device is assigned
to an address other than addresses 0 to 30
The TA720 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 [GP-IB] menu of the
UTILITY 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 that return multiple response
messages
See the example of the commands given in
chapter 4.
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
See the example of the commands given in
chapter 4.
6 Options included in command function
elements and composite header elements
See chapters 3 and 4.
7 Buffer size which affects transmission of block
data
The receive buffer size of block data is 64 KB.
App-4
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
See the example of the commands given in chapter
4.
10 Communications between devices which do not
follow the response syntax
None.
11 Size of data block of response data
0 to 4096000 bytes
12 List of supported common commands
See section 4.23, "Common Command Group."
13 Condition of device when calibration is
successfully completed
The settings return to the conditions that existed
before the calibration, measurements are
terminated, and previous measured data are
invalidated.
14 Maximum length of block data which can be
used for definition of *DDT trigger macro
Not supported.
15 Maximum length of macro label used in
definition of macro, 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?
See section 4.23, "Common Command Group."
17 Size of storage area for protected user data for
PUD and *PUD?
*PUD and *PUD? are not supported.
18 Length of *RDT and *RDT? resource name
*RDT and *RDT? are not supported.
19 Change in status due to *RST, *LRN?, *RCL and
*SAV
*RST
See section 4.23, "Common Command Group."
*LRN?, *RCL, *SAV
These common commands are not supported.
20 Execution range of self-test using the *TST?
This command executes the same Board test as the
Selftest menu of the UTILITY key.
21 Structure of extended return status
See chapter 4.
22 To find out whether each command is
performed in parallel or sequentially
See section 3.5, "Synchronization with the
Controller" and chapter 4.
23 Description of execution of each command
See the functions of each command in chapter 4
and TA720 User's Manual.
