Devices that are connected with the GP-IB cable have their own unique address within
the GP-IB system. This address is used to identify the different devices. Therefore,
when connecting the instrument to another device such as a PC, the address of the
instrument must be selected. The address is selected from the following range. The
default setting is [1].
Selectable range: 0 to 30

1.5 Responses to Interface Messages
1.5 Responses to Interface Messages
What is an Interface Message?
An interface message (also called an interface command or bus command) is issued by
the controller. Interface messages are classified as follows.
Uni-line messages
Messages are transferred through a single control line. The following three types of uniline message are available.
• IFC (Interface Clear)
• REN (Remote Enable)
• IDY (Identify)
Multi-line messages
Eight data lines are used to transmit a message. Multi-line messages are classified as
follows.
Address commands
Valid when a piece of equipment is designated as a listener or a talker. The following
five address commands are available.
• Commands valid for pieces of equipment designated as listeners
GTL (Go To Local)
SDC (Selected Device Clear)
PPC (Parallel Poll Configure)
GET (Group Execute Trigger)
• Command valid for pieces of equipment designated as talkers
TCT (Take Control)
Universal commands
Valid for any item of equipment, irrespective of whether the item is designated as a
listener or a talker. The following five universal commands are available.
LLO (Local Lockout)
DCL (Device Clear)
PPU (Parallel Poll Unconfigure)
SPE (Serial Poll Enable)
SPD (Serial Poll Disable)
In addition to the above commands, a listener address, talker address or secondary
command can be sent in an interface message.
Differences between SDC and DCL
The SDC command is an address command and requires that both the talker and
listener be designated. DCL is a universal command and does not require that the
talker and listener be designated. Hence, SDC is used for specific items of equipment,
while DCL can be used for any equipment connected to the communications bus.

2.1 Messages
Messages
Blocks of message data are transferred between the
controller and this instrument during communications.
Messages sent from the controller to this instrument
are called program messages, and messages sent
back from this instrument to the controller are called
response messages.
If a program message contains a query command, i.e.
a command which requests a response, this
instrument returns a response message. A single
response message is always returned in reply to a
program message.
Program Messages
As explained above, the data (message) sent from the
controller to this instrument is called a program
message. The format of a program message is shown
below.
;
Program message unit
<PMT>
<PMT>
PMT is a terminator used to terminate each program
message. The following three types of terminator 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 attached
(NL is not included in the program
message.)
Program message unit format
The format of a program message unit is shown below.
<Program header>
A program header is used to indicate the command
type. For details, refer to page 2-3.
2
Before Programming
<Program message unit>
A program message consists of zero or more program
message units; each unit corresponds to one
command. This instrument executes commands one
by one according to the order in which they are
received.
Program message units are delimited by a ";".
For a description of the format of the program
message unit, refer to the explanation given further
below.
Example
:MEASURE:MODE HHISTOGRAM;FUNCTION PERIOD,A<PMT>
Unit Unit
<Program data>
If certain conditions are required for the execution of a
command, program data must be added. Program data
must be separated from the header by a space (ASCII
code "20H"). If multiple items of program data are
included, they must be separated by a
"," (comma).
For details, refer to page 2-5.

<Response message unit>
<RMT>
<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 [ ;].
For the response message format, refer to the next
page.
Example
:SAMPLE:GATE:MODE EXTERNAL;POLARITY POSITIVE<RMT>

<RMT>
RMT is the terminator used for every response
message. Only one type of response message is
available;
NL^END.
Response message unit format
The format of a program message unit is shown below.
,
<Rsps. header> <Response data>
Space
<Response header>
A response header sometimes precedes the response
data. Response data must be separated from the
header by a space. For details, refer to page 2-4.
<Response data>
Response data is used to define a response. If multiple
items of response data are used, they must be
separated by a "," (comma). For details, refer to page
2-5.
Example
500.0E-03<RMT> :SAMPLE:INTERVAL MINIMUM<RMT>
Data Header Data
If a program message contains more than one query,
responses are made in the same order as the queries.
Normally, each query returns only one response
message unit, but there are some queries which return
more than one response message unit. The first
response message unit always responds to the first
query, but it is not always true that the 'n'th unit
always responds to the
'n'th query. Therefore, if you
want to make sure that a response is made to each
query, the program message must be divided up into
individual messages.
Points to Note concerning Message Transmission
• 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 received
will 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.
Dead Lock
This instrument has a buffer memory in which both
program and response messages of 1024 bytes or
more can be stored. (The number of bytes available
will vary depending on the operating state of the
instrument.) If both buffer memories become full at the
same time, this instrument becomes inoperative. This
state is called dead lock. In this case, operation can be
resumed by discarding the response message.
No dead lock will occur, if the size of the program
message including the PMT is kept below 1024 bytes.
Furthermore, no dead lock will occur if the program
message does not contain a query.

2.2 Commands
2.2 Commands
Commands
There are three types of command (program header)
which can be sent from the controller to this
instrument. They differ in the format of their program
headers.
They are
• Common command header
• Compound header
• Simple header
Common Command Header
Commands defined in IEEE 488.2-1992 are called
common commands. The header format of a common
command is shown below. An asterisk (
be attached to the beginning of a command.
*
<Mnemonic>
?
An example of a common command
*CLS
*) must always
When Concatenating Commands
Command Group
A command group is a group of commands which have
the same compound header. A command group may
contain sub-groups.
Example Commands relating to the sampling
SAMPLE? SAMPLE:GATE?
SAMPLE:GATE:MODE SAMPLE:GATE:EVENTSIZE
SAMPLE:GATE:POLARITY SAMPLE:GATE:TIME
SAMPLE:INTERVAL SAMPLE:ARMING:SOURCE
SAMPLE:ARMING:DELAY:MODE
SAMPLE:ARMING:DELAY:TIME
When Concatenating Commands of the Same
Group
This instrument stores the hierarchical level of the
command which is currently being executed, and
performs analysis on the assumption that the next
command to be sent will also belong to the same level.
Therefore, it is possible to omit the header if the
commands belong to the same group.
2
Before Programming
Compound Header
Commands designed to be used only with this
instrument are classified and arranged in a hierarchy
according to their function. The format of a compound
header is illustrated below. A colon ( :) must be used
when specifying a lower-level header.
:
<Mnemonic>
?:
An example of a compound header
MEASURE:FUNCTION
Simple Header
These commands (headers) are functionally
independent of each other and are not arranged
hierarchically. The format of a simple header is shown
below.
<Mnemonic>
?:
An example of a simple header
START
Note
A mnemonic is a character string made up of alphanumeric
characters.
Example
INPUT:ACHANNEL:COUPLING AC;IMPEDANCE
I50<PMT>
When Concatenating Commands of Different
Groups
A colon ( :) must be included before the header of a
command, if the command does not belong to the
same group as the preceding command.
Example MEASURE:MODE TSTAMP;:DISPLAY:ITEM
LIST<PMT>
When Concatenating Simple Headers
When you type in a simple header after another
command, you must include a colon ( :) before the
simple header.
Example
MEASURE:MODE TSTAMP;:START<PMT>
When Concatenating Common Commands
Common commands defined in IEEE 488.2-1992 are
independent of hierarchical level. Thus, it is not
necessary to add a colon (
:) before a common
command.
Example
MEASURE:MODE TSTAMP;*CLS;FUNCTION
DUTY,A<PMT>
2-3IM 704310-12E
2.2 Commands
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 command
even when commands of the same command group
are being concatenated.
Example
MEASURE:MODE TSTAMP<PMT>MEASURE:
FUNCTION DUTY,A<PMT>
Upper-level Query
An upper-level query is a compound header to which a
question mark is appended. Execution of an upperlevel query allows all a group
's settings to be output at
once. Some query groups comprising more than three
hierarchical levels can output all their lower level
settings.
Example
MEASURE?<PMT>→:MEASURE:
MODE HHISTOGRAM;FUNCTION PERIOD,A;
SLOPE RISE
In reply to a query, a response can be returned as a
program message to this instrument. Transmitting a
response can restore the settings made when the
query was executed. However, some upper-level
queries will not return set-up data which is not currently
in use. Note that not all a group
's information will
necessarily be sent out as a response.
Header Interpretation Rules
This instrument interprets the header received
according to the following rules.
• Mnemonics are not case sensitive.
Example
"MEASure" can also be written as
"measure" or "Measure".
• The lower-case part of a header can be omitted.
Example "MEASure" can also be written as
"MEASU" or "MEAS".
• If the header ends with a question mark, the
command is a query. It is not possible to omit the
question mark.
Example "MEASure?" cannot be abbreviated to
• If the
"x" at the end of a mnemonic is omitted, it is
assumed to be
Example If
anything shorter than
"1".
"WINDow<x>" is written as "WIND", this
represents
"WINDow1".
"MEAS?".
• Any part of a command enclosed by [ ] can be
omitted.
Example
CALCulation[:WINDow1]:AVERage? can
be written as
"CALCulation:AVERage?".
However, a part enclosed by [ ] cannot be omitted if is
located at the end of an upper-level query.
2-4 IM 704310-12E
2.3 Response/2.4 Data
2.3 Response
On receiving a query from the controller, this
instrument returns a response message to the
controller. A response message is sent in one of the
following two forms.
• Response consisting of a header and data
If the query can be used as a program message
without any change, a command header is attached
to the query, which is then returned.
Example
• Response consisting of data only
If the query cannot be used as a program message
unless changes are made to it (i.e. it is a query-only
command), no header is attached and only the data
is returned. Some query-only commands can be
returned after a header is attached to them.
Example STATUS:ERROR?<PMT>→
When returning a response without a header
It is possible to remove the header from a response
consisting of a header and data. The
"COMMunicate:HEADer" command is used to do this.
Abbreviated form
Normally, the lower-case part is removed from a
response header before the response is returned to
the controller. Naturally, the full form of the header can
also be used. For this, the "COMMunicate:VERBose"
command is used. The part enclosed by [ ] is also
omitted in the abbreviated form.
SAMPLE:GATE:MODE?<PMT>→:
SAMPLE:GATE:MODE EVENT<RMT>
0,"NO ERROR"<RMT>
2.4 Data
Data
A data section comes after the header. A space must
be included between the header and the data. The
data contains conditions and values. Data is classified
as below.
Data Description
<Decimal> Value expressed as a decimal number
(Example: CH2's probe attenuation
→SAMPle:GATE:EVENtsize 100)
<Voltage><Time> Physical value
(Example: Gate time
<Percent> →SAMPle:GATE:TIME 1US)
<Register> Register value expressed as either binary, octal, decimal
or hexadecimal
(Example: Extended event register value
→STATus:EESE #HFE)
<Character data> Specified character string (mnemonic). Can be selected
from { }
(Example: Selecting of gate mode
→SAMPle:GATE:MODE {EVENt|TIME|EXTernal})
<Boolean> Indicates ON/OFF. Set to ON, OFF or value
(Example: Panorama display ON
→DISPlay:PANorama:STATe ON)
<Character string data>Arbitrary character string
(Example: File name to be saved
→FILE:DELete:SETup "SETUP_1")
<Block data> Arbitrary 8-bit data
(Example: Response to acquired waveform data
→#6000010ABCDEFGHIJ)
<Decimal>
<<Decimal> indicates a value expressed as a decimal
number, as shown in the table below. Decimal values
are given in the NR form specified in ANSI X3. 42-
1975.
Symbol Description Example
<NR1> Integer 125 –1 +100000
<NR2> Fixed point number 125.0 –.90 +001.
<NR3> Floating point number 125.0E+0 –9E–1 +.1E4
<NRf> Any of the forms <NR1> to <NR3> is allowed.

Before Programming
• Decimal values which are sent from the controller to
this instrument can be sent in any of the forms to
<NR3>. In this case, <NRf> appears.
• For response messages which are returned from
this instrument to the controller, the form (<NR1> to
<NR3> to be used) is determined by the query. The
same form is used, irrespective of whether the value
is large or small.
• In the case of <NR3>, the "+" after the "E" can be
omitted, but the
"–" cannot.
• If a value outside the setting range is entered, the
value will be normalized so that it is just inside the
range.
• If the value has more than the significant number of
digits, the value will be rounded.

<Register>
<Register> indicates an integer, and can be expressed
in hexadecimal, octal or binary as well as as a decimal
number. <Register> is used when each bit of a value
has a particular meaning. <Register> is expressed in
one of the following forms.
Form Example
<NRf> 1
#H<Hexadecimal value made up of the digits 0 to 9, and A to F> #H0F
#Q<Octal value made up of the digits 0 to 7> #q777
#B<Binary value made up of the digits 0 and 1> #B001100
• <Register> is not case sensitive.
• Response messages are always expressed as
<NR1>.
<Character Data>
<Character data> is a specified string of character data
(a mnemonic). It is mainly used to indicate options, and
is chosen from the character strings given in { }. For
interpretation rules, refer to "Header Interpretation
" on page 2-4.
Rules
Form Example
{EVENt|TIME|EXTernal} EVENt
• As with a header, the "COMMunicate:VERBose"
command can be used to return a response
message in its full form. Alternatively, the
abbreviated form can be used.
• The
"COMMunicate:HEADer" command does not
affect <character data>.
• <Multiplier> and <Unit> are not case sensitive.
• [U] is used to indicate [ µ].
• [MA] is used for Mega (M) to distinguish it from Mili.
• If both <Multiplier> and <Unit> are omitted, the
default unit will be used.
• Response messages are always expressed in
<Boolean>
<Boolean> is data which indicates ON or OFF, and is
expressed in one of the following forms.
Form Example
{ON|OFF|<NRf>} ON OFF 1 0
<NR3> form. Neither <Multiplier> nor <Unit> is
used, therefore the default unit is used.
• When <Boolean> is expressed in <NRf> form, OFF
is selected if the rounded integer value is [0] and ON
is selected if the rounded integer is [Not 0].
• A response message is always [1] if the value is ON
and [0] if it is OFF.

2.4 Data/2.5 Synchronization with the Controller
<Character String Data>
<Character string data> is not a specified character
string like <Character data>. It is an arbitrary character
string. A character string must be enclosed in single
quotation marks ( ') or double quotation marks ( ").
Form Example
<Character string data> 'ABC' "IEEE488.2-1987"
• Response messages are always enclosed in double
quotation marks.
• If a character string contains a double quotation
mark (
"), the double quotation mark will be replaced
by two concatenated double quotation marks (
"").
This rule also applies to a single quotation mark
within a character string.
• <Character string data> is an arbitrary character
string, therefore this instrument assumes that the
remaining program message units are part of the
character string if no single ( ') or double quotation
mark (
") is encountered. As a result, no error will be
detected if a quotation mark is omitted.
<Block data>
<Block data> is arbitrary 8-bit data. <Block data> is
only used for response messages. Response
messages are expressed in the following form.
Form Example
#8<8-digit decimal value><Data byte string> #8000010ABCDEFGHIJ
•#8
Indicates that the data is <Block data>.
• <6-digit decimal value>
Indicates the number of bytes of data. (
000010=10
bytes)
• <Data byte string>
The actual data. ( ABCDEFGHIJ)
• Data is comprised of 8-bit values (0 to 255). This
means that the ASCII code [0AH], which stands for
[NL], can also be a code used for data. Hence, care
must be taken when programming the controller.
2.5 Synchronization with the Controller
On the TA520, there are no overlap commands which
permit the execution of the next command before the
execution of the previous command completes. If
multiple commands are sent sequentially, the
execution of the next command is held until the
execution of the previous command completes.
How to Achieve Synchronization
Synchronization is sometimes required for reasons
other than communications related reasons, such as
the activation of a trigger.
For example, if the program message (see below) is
transmitted to make an inquiry about the data which is
acquired during single measurement, the
"MEMory:SEND?" command will be executed whether
acquisition has been completed or not, causing a
command execution error.
:SSTart;:MEMory:SEND?<PMT>
In this case, synchronization with the time at which
acquisition is completed must be accomplished, as
shown below.
Using STATus:CONDition? query
A
"STATus:CONDition?" query is used to make an
inquiry about the contents of the condition register
(page 4-4). It is possible to judge whether acquisition
is in progress or not by reading bit 0 of the condition
register. The measured data is effective if bit 0 is "1".
"0", acquisition is in progress, thus the
If it is
measured data is not effective.
Example
:SSTart<PMT>
STATus:CONDition?<PMT>
(Returns to the previous status if bit 0 is
found to be [1] when the response is
decoded.)
MEMory:SEND?<PMT>
2
Before Programming
A "MEMory:SEND?" query will not be executed until bit
0 of the condition register has been set to [
1].
2-7IM 704310-12E
2.5 Synchronization with the Controller
Using the extended event register
Changes in the condition register are reflected in the
extended event register (page 4-4).
Example STATus:FILTer1 RISE;:STATus:EESE 1;
EESR?;*SRE 8;SSTart<PMT>
(Service request is awaited.)
MEMory:SEND?<PMT>
"STATus:FILTer1 RISE" indicates that the transit filter
is set so that bit 0 (
"1" when bit 0 of the condition register is
set to
changed from [
"STATus:EESE 1" is a command used to reflect the
FILTer1) of the extended register is
0] to [1].
status of only bit 0 of the extended event register in the
status byte.
"STATus:EESR?" is used to clear the extended event
register.
The "*SRE" command is used to generate a service
request caused by the extended event register only.
"MEMory:SEND?" will not be executed until a service
request is generated.
Using the COMMunicate:WAIT command
The "COMMunicate:WAIT" command halts
communications until a specific event is generated.
Example
STATus:FILTer1 RISE;:STATus:EESR?;
SSTart<PMT>
(Response to STATus:EESR? is decoded.)
COMMunicate:WAIT 1;:MEMory:
SEND?<PMT>
For a description of "STATus:FILTer1 RISE" and
"STATus:EESR?", refer to "Using the extended event
register
"COMMunicate:WAIT 1" means that communications is
" on this page.
halted until bit 0 of the extended event register is set to
[1].
"MEMory:SEND?" will not be executed until bit 0 of the
extended event register is set to [
1].
