8.1
About the IEEE.488.2-1992 Standard
The GP-IB interface for this instrument complies with
the IEEE 488.2-1992 standard. This standard requires
that the following twenty-three items be included with
documentation. Those items are described below.
(1)The subsets of the IEEE 488.1 interface
functions that are supported
See "GP-IB Interface Specifications" on page 8-3.
(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 is recognized at the moment the
address is changed using the Utility menu (see
section 8.4). The newly set address is valid until it
is changed again.
(4)Device settings at power-up. Commands which
can be used at power ON
Basically, the previous settings are used (settings
that existed when the power was turned OFF). All
commands can be used at power-up.
(5)Message exchange options
(a)Input buffer size
1024 bytes
(b)Queries that return multiple response
messages
See section 10.2 for examples with each
command.
(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 in which the response data
are created upon receiving a send request from
the controller.
(e)Commands that have parameters that restrict
one another
See section 10.2 for examples with each
command.
IM 704610-01E
(6)Items that include function elements consisting
of commands and elements with compound
headers
See sections 10.1 and 10.2.
(7)Buffer sizes that affect block data transmission
The buffer size of block data is 64 KB.
(8)A list of program data elements that can be used
in equations and their nesting limitations
Equations cannot be used.
(9)Syntax of the responses to queries
See section 10.2 for examples with each command.
(10)Communication between devices that do not
follow the response syntax
Not supported.
(11)Size of the response data block
0 to 524284 bytes.
(12)A list of supported common commands
See section 10.2.20, "Common Command Group."
(13)Device condition after a successful calibration
The settings return to the conditions that existed
before the calibration, measurements are
terminated, and previous measured data are
invalidated.
(14)Maximum length of blocks used in the *DDT
trigger macro definition
Not supported.
(15)Maximum length of the macro label in the
macro definition, maximum length of program
data used in the macro definition, and
processing when recursion is used in the macro
definition.
Macro function not supported.
(16)Reply to the *IDN? query
See section 10.2.20, "Common Command Group."
(17)The size of the storage area for protected user
data for *PUD and *PUD? commands
*PUD and *PUD? are not supported.
