3.1 Messages
Messages
Messages are used to exchange information between
the controller and the instrument. Messages that are
sent from the controller to the instrument are called
program messages and messages that are sent
back from the instrument to the controller are called
response messages.
If a program message contains a message unit that
requests a response (a query), the instrument returns
a response message upon receiving the program
message. A single response message is always
returned in response to a single program message.
Program Messages
Program Message Unit
A program message consists of zero or more
program message units; each unit corresponds to
one command. The instrument executes the received
commands in order.
Each program message unit is separated by a
semicolon (;).
Program Data
If certain conditions are required in executing a
command, program data is added. A space (ASCII
code “20H”) separates the program data from the
header. If there are multiple sets of program data, they
are separated by commas (,). For details, see section
3.4, “Data.”
Response Messages
Response Message Units
A response message consists of one or more
response message units: each response message unit
corresponds to one response. Response message
units are delimited by a ";" (semicolon).
<RMT>
RMT stands for “response message terminator.” The
response message terminator is NL^EOM.
Before Programming
<PMT>
PMT is a program message terminator. The following
three types are available.
• NL (New Line)
Same as LF (Line Feed). ASCII code"0AH" is used.
• ^END
END message defined in IEEE488.1. (EOI signal)
(The data byte sent with an END message will be
the final item of the program message unit.)
• NL^END
NL with an END message added (NL is not included
in the program message unit.)
Program Header
A program header is used to indicate the command
type. For details, see section 3.2, “Commands.”
A response header sometimes precedes the response
data. A space separates the data from the header. For
details, see section 3.3, “Response.”
Response Data
Response data contains the content of the response.
If there are multiple sets of response data, they are
separated by commas (,). For details, see section 3.4,
“Data.”
If there are multiple queries in a program message,
responses are returned in the same order that the
queries were received in. The AQ1200 returns a single
response message unit to most queries, but there
are queries that the AQ1200 returns multiple units to.
The first response message unit always corresponds
to the first query, but the nth response unit may not
necessarily correspond to the nth query. If you want to
make sure that every response is retrieved, divide the
program messages into individual messages.

IM AQ1200-17EN
3.1 Messages
Note
• It is always possible to send a program message if the
previous message which was sent did not contain any
queries.
• If the previous message contained a query, it is not
possible to send another program message until a
response message has been received. An error will
occur if a program message is sent before a response
message has been received in its entirety. A response
message which has not been receivedwill be discarded.
• If an attempt is made by the controller to receive
a response message, even if there it no response
message, an error will occur. An error will also occur if
the controller makes an attempt to receive a response
message before transmission of a program message has
been completed.
• If a program message of more than one unit is sent
and some of the units are incomplete, this instrument
receives program message units which the instrument
thinks complete and attempts to execute them. However,
these attempts may not always be successful and
a response may not always be returned, even if the
program message contains queries.

3.2 Commands
Command
There are three types of commands (program headers)
that a controller may send to the AQ1200. The
commands differ in their program header formats.
Common Command Header
Commands that are defined in IEEE 488.2-1987 are
called common commands. Be sure to include an
asterisk (*) at the beginning of a common command.
Common command example
*CLS
Compound Header
Other commands that are specific to the AQ1200 are
classified and arranged in a hierarchy according to
their functions. Be sure to use a colon to specify a
lower hierarchical level.
Compound header example
:PMETer:LINK:STATe
When Concatenating Commands
Command Groups
A command group is a group of commands that have
common compound headers arranged in a hierarchy. A
command group may contain sub-groups.
Example
Commands relating to acquisition settings
:PMETer:DREF
:PMETer:LINK:STATe
:PMETer:MAXMin:STATe
:PMETer:MODulation
:PMETer:OFFSet
:PMETer:REFerence
:PMETer:WAVelength:DETail
When Concatenating Commands of the Same
Group
The AQ1200 stores the hierarchical level of the
command that is currently being executed and
processes the next command on the assumption that
it belongs to the same level. Therefore, the common
header section can be omitted for commands that
belong to the same group.
Example
:PMETer:MODulation MOD_CW;UNIT DB<PMT>
When Concatenating Common Commands
Common commands that are defined in the IEEE
488.2-1987 are independent of hierarchy. There is no
need to use a colon.
Example
:PMETer:MODulation MOD_CW;*CLS;UNIT
DB<PMT>
When Separating Commands with <PMT>
If a terminator is used to separate two commands,each
command is a separate message. Therefore,
the common header must be typed in for each
commandeven when commands of the same command
groupare being concatenated.
Example
:PMETer:MODulation MOD_CW<PMT>:PMETer
UNIT DB<PMT>
Upper-level Query
An upper-level query is a query that is made by
appending a question mark to the highest level
command of a group. The controller can receive all
of the settings in a group collectively by executing
an upper-level query. Some upper-level queries of a
group, which may be comprised of more than three
hierarchical levels, can cause the AQ1200 to transmit
all the lower level settings.
Example
:NETWork:CONTrol?<PMT> -> :NETW:CONT:
PASS "ABC";TIM 30;USER "anonyumous"
Note
• The response to an upper-level query can be sent back
to the AQ1200 as a program message. This enables the
settings that were present when the upper-level query
was made to be reproduced later on.
• Some upper-level queries do not return setup data that is
not currently in use. Exercise caution because not all of a
group’s information is necessarily returned in a response.
Before Programming
When Concatenating Commands of Different
Groups
If the subsequent command does not belong to the same
group, place a colon in front of the header (cannot be omitted).
Example
:PMETer:MODulation MOD_CW;:MENU:
FUNCtion TOP<PMT>
IM AQ1200-17EN

IM AQ1200-17EN
3.2 Commands
Header Interpretation Rules
The AQ1200 interprets the header that it receives
according to the rules below.
Example
"
DRANge
" can be written as "
drange
" or "
Drange
• The lower-case characters can be omitted.
Example
"
DRANge
" can be written as "
DRANG
" or "
DRAN
."
• The question mark at the end of a header indicates
that it is a query. You cannot omit the question mark.
Example
The
shortest abbreviation for "
DRANge?
" is "
DRAN?
• If the <x> (value) at the end of a mnemonic is
omitted, it is interpreted as a 1.
Example
M<x>,
If you write "
M
" for "
" "M1." is specified.
Note
A mnemonic is a character string made up of
alphanumeric characters.)
."
."

3.3 Response
Form
When the controller sends a query with a question
mark, the AQ1200 returns a response message to the
query.
Response Consisting of a Header and Data
Responses that can be used as program messages
without any changes are returned with command
headers attached.
Example
:PMETer:MODulation?<PMT>
-> :PMETer:MODulation MOD_270HZ<RMT>
If You Want the AQ1200 to Return Responses
without Headers
You can configure the AQ1200 so that even responses
that have both headers and data are returned without
headers. Use the COMMunicate:HEADer command for
this purpose.
Abbreviated Form
The AQ1200 normally returns response headers with
the lower-case section removed. You can configure
the AQ1200 so that full headers are returned. Use the
COMMunicate:VERBose command for this purpose.
