• Talker capability

Outputs setup information, measured data, and other information.

Note

Listen-only, talk-only, and controller capabilities are not available on this instrument.

Switching between Remote and Local Modes

• When switching from local to remote mode

Receiving a REN (Remote Enable) message from the controller when the instrument is in the local mode causes the instrument to switch to the remote mode.

• REMOTE indication appears at the upper right corner of the screen (see page 1-1).

• All keys other than the LOCAL (SHIFT+AUTO SCALE) key are locked.

• The settings that existed in the local mode are maintained even when the instrument switches to the remote mode.

• When switching from remote to local mode

Pressing the LOCAL (SHIFT+AUTO SCALE) key when the instrument is in the remote mode causes the instrument to switch to the local mode. However, this act is invalid if the instrument has been set to Local Lockout mode (see page 1-6) by the controller.

• REMOTE indication at the upper right corner of the screen disappears.

• Key operations are enabled.

• The settings that existed in the remote mode are maintained even when the instrument switches to the local mode.

1.5 Responses to Interface Messages

What Is an Interface Message

Interface messages are also referred to as interface commands or bus commands. They are commands that are issued by the controller. They are classified as follows:

• Uni-line messages

A single control line is used to transmit uni-line messages. The following three types are available. IFC (Interface Clear), REN (Remote Enable), and IDY (Identify)

• Multi-line messages

Eight data lines are used to transmit multi-line messages. The messages are classified as follows:

• Address commands These commands are valid when the instrument is designated as a listener or as a talker. The following five types are available.

• Commands that are valid on an instrument that is designated as a listener

GTL (Go To Local), SDC (Selected Device Clear), PPC (Parallel Poll Configure), and GET (Group Execute Trigger)

• Commands that are valid on an instrument that is designated as a talker

TCT (Take Control)

• Universal commands These commands are valid on all instruments regardless of the listener and talker designations. The following five types are available. LLO (Local Lockout), DCL (Device Clear), PPU (Parallel Poll Unconfigure), SPE (Serial Poll Enable), and SPD (Serial Poll Disable)

• In addition, listener address, talker address, and secondary commands are also considered interface messages.

• The differences between SDC and DCL In multi-line messages, SDC messages are those that require talker or listener designation and DCL messages are those that do not require the designation. Therefore, SDC messages are directed at a particular instrument while DCL messages are directed at all instruments on the bus.

Responses to Interface Messages

• Responses to a uni-line message

• IFC: Clears the talker and listener functions. Stops output if data are being

output.

• REN: Switches between the remote and local modes.

• IDY: Not supported.

• Responses to a multi-line message (address command)

• GTL: Switches to the local mode.

• SDC: Clears the program message (command) being received and the

output queue (see page 5-5).

• GET: Same operation as the *TRG command.

• The COMMunicate:WAIT command is immediately terminated.

• PPC or TCT: Not supported.

• Responses to a multi-line message (universal command)

• LLO: Disables the LOCAL key on the front panel to prohibit switching to the

local mode.

• DCL: Same operation as the SDC message.

• SPE: Sets the talker function on all devices on the bus to serial polling mode.

The controller polls the devices in order.

• SPD: Clears the serial polling mode of the talker function on all devices on the bus.

• PPU: Not supported.

Switching between Remote and Local Modes

• When switching from local to remote mode

If the TA720 receives a “:COMMunicate:REMote ON” command from the PC when it is in the local mode, it switches to the remote mode.

• REMOTE is displayed at the upper left corner of the screen.

• All keys except the LOCAL (SHIFT+AUTO SCALE) key are disabled.

• The settings that existed in the local mode are maintained even when the instrument switches to the remote mode.

• When switching from remote to local mode

Pressing the LOCAL (SHIFT+AUTO SCALE) key when the instrument is in the remote mode causes the instrument to switch to the local mode. However, this is void when the TA720 has received a “:COMMunicate:LOCKout ON” command from the PC (local lockout condition). When the TA720 receives a “:COMMunicate:REMote OFF” command from the PC, the TA720 switches to the local mode regardless of the local lock condition.

• REMOTE indication at the upper right corner disappears.

• Key operations are enabled.

• The settings that existed in the remote mode are maintained even when the instrument switches to the local mode.

Note

The Ethernet communication interface cannot be used concurrently with the GP-IB interface.

User Verification Function

When using the Ethernet communication interface, a user name and password are required when connecting to the network. The user name and password are set on the User Account pop-up window under the Utility menu of the TA720. For details, see section 2.4, “Setting the TA720.”

Chapter 3 Program Syntax and Programming

<Program data>Space

3.1 Messages

Message

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 Message

Data that is sent from the controller to the instrument are called program messages. The program message format is shown below.

;

A program message consists of one 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 (;). For details regarding the format of the program message unit, see the next section.

<PMT>

PMT is a program message terminator. The following three types are available. NL (New Line): Same as LF (Line Feed). ASCII

code “0AH”

^END: END message that is defined in

IEEE488.1 (EOI signal)

(The data byte that is sent simultaneously with the END message is the last data of the program message.)

NL^END: NL with an END message added

(NL is not included in the program message.)

• Program Message Unit Format

The program message unit format is shown below.

The program header indicates the command type. For details, see page 3-3.

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 page 3-5.

<RMT>

A response message consists of one or more response message units; each response message unit corresponds to one response. Response message units are separated by a semicolon (;). For details regarding the format of the response message unit, see page 3-4.

Example

:SAMPLE:GATE:MODE EXTERNAL;POLARITY POSITIVE<RMT>

Unit Unit

<RMT>

A response message terminator. It is NL^END.

• Response Message Unit Format

The response message unit format is shown below.

<Response header> <Response data>Space

A response header sometimes precedes the response data. A space separates the data from the header. For details, see page 3-4.

Response data contains the content of the response. If there are multiple sets of response data, they are separated by commas (,). For details, see page 3-5.

Example

500.0E-03<RMT> :SAMPLE:INTERVAL MINIMUM<RMT>

Data Header Data

If there are multiple queries in a program message, responses are made in the same order as the queries. In most cases, a single query returns a single response message unit, but there are a few queries that return multiple units. The first response message unit always corresponds to the first query, but the nth response unit may not necessarily correspond to the nth query. Therefore, if you want to make sure that every response is retrieved, divide the program messages into individual messages.

Precautions to Be Taken when Transferring Messages

• If a program message that does not contain a query is sent, the next program message can be sent at any time.

• If a program message that contains a query is sent, a response message must be received before the next program message can be sent. If the next program message is sent before the response message is received in its entirety, an error occurs. The response message that was not received is discarded.

• If the controller tries to receive a response message when there is none, an error occurs. If the controller tries to receive a response message before the transmission of the program message is complete, an error occurs.

• If a program message containing multiple message units is sent, and the message contains incomplete units, the instrument will attempt to execute the ones that are believed to be complete. However, these attempts may not always be successful. In addition, if the message contains queries, the responses may not be returned.

Deadlock

The instrument can store in its buffer program and response messages of length 1024 bytes or more (The number of available bytes varies depending on the operating conditions). When both the transmit and receive buffers become full at the same time, the instrument can no longer continue to operate. This state is called a deadlock. In this case, operation can be resumed by discarding the program message. Deadlock will not occur if the program message (including the <PMT>) is kept below 1024 bytes. Furthermore, deadlock never occurs if a program message does not contain a query.

3-2 IM 704510-17E

3.2 Commands

Command

There are three types of commands (program headers) that are sent from the controller to the instrument. They differ in their program header formats.

Common Command Header

Commands that are defined in the IEEE 488.2-1992 are called common commands. The header format of a common command is shown below. An asterisk (*) is always placed in the beginning of a command.

An example of a common command: *CLS

Compound Header

Dedicated commands used by the instrument are classified and arranged in a hierarchy according to their functions. The format of a compound header is shown below. A colon (:) must be used to specify a lower hierarchy.

An example of a compound header:

MEASURE:FUNCTION

When Concatenating Commands

• Command Group

A command group is a group of commands that

have common compound headers arranged in a hierarchy. A command group may contain subgroups.

Example Group of commands related to 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

The instrument stores the hierarchical level of the

command that is currently being executed, and performs analysis on the assumption that the next command sent will also belong to the same level. Therefore, common header sections can be omitted for commands belonging to the same group.

Example :INPUT:ACHANNEL:COUPLING AC;

IMPEDANCE I50<PMT>

Program Syntax and Programming

Simple Header

These commands are functionally independent and do not have a hierarchy. The format of a simple header is shown below.

An example of a simple header: START

Note

A <mnemonic> is a character string made up of alphanumeric characters.

• When Concatenating Commands of Different Groups

If the following command does not belong to the

same group, a colon (:) is placed in front of the header.

Example :MEASURE:MODE TSTAMP;:DISPLAY:

ITEM LIST<PMT>

• When Concatenating Simple Headers

If a simple header follows another command, a

colon (:) is placed in front of the simple header.

Example :MEASURE:MODE TSTAMP;:

START<PMT>

• When Concatenating Common Commands

Common commands that are defined in the IEEE

488.2-1992 are independent of hierarchy. Colons (:) are not needed before a common command.

Example :MEASURE:MODE TSTAMP;*CLS;

FUNCTION PERIOD,A<PMT>

3-3IM 704510-17E

3.2 Commands/3.3 Responses

• 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 specified for each command even when commands belonging to the same command group are being concatenated. Example :MEASURE:MODE TSTAMP<PMT>:

MEASURE:FUNCTION PERIOD,A<PMT>

Upper-level Query

An upper-level query is a query in which a question mark (?) is appended to the highest level command of a group. Execution of an upper-level query allows all settings that can be specified in the group to be received at once. Some query groups which are comprised of more than three hierarchical levels can output all the lower level settings. Example :MEASURE?<PMT> -> :MEASURE:

MODE HHISTOGRAM; FUNCTION PERIOD,A;SLOPE RISE

The response to an upper-level query can be transmitted as a program message back to the instrument. In this way, the settings that existed when the upper-level query was made can be restored. However, some upper-level queries will not return setup information that is not currently in use. It is important to remember that not all the group’s information is necessarily returned as part of a response.

Header Interpretation Rules

The instrument interprets the header that is received according to the rules below.

• Mnemonics are not case sensitive. Example MEASure can be also written as

measure or Measure.

• The lower-case section of the header can be omitted. Example MEASure can also be written as MEASU

or MEAS

• The question mark (?) at the end of a header indicates that it is a query. The question mark (?) cannot be omitted. Example The shortest abbreviation for

“MEASure?” is “MEAS?.”

• If the <x> (value) at the end of a mnemonic is omitted, it is interpreted as a 1. Example If WINDow<x> is written as WIND, this

represents WINDow1.

• The section enclosed by braces ([]) can be omitted. Example :CALCulation[:WINDow1]:

AVERage? can be written as :CALCulation:AVERage?.

However, the last section enclosed by braces ([]) cannot be omitted in an upper-level query.

3.3 Responses

When the controller sends a message unit that has a question mark (?) in its program header (query), the instrument returns a response message to the query. A response message is returned in one of the following two forms.

• Response consisting of a header and data If the response can be used as a program message without any change, it is returned with a command header attached. Example :SAMPLE:GATE:MODE?<PMT> ->

:SAMPLE:GATE:MODE EVENT<RMT>

• Response consisting of data only If the response cannot be used as a program message unless changes are made to it (query-only command), only the data section is returned. However, there are query-only commands that return responses with the header attached. Example :STATUS:ERROR?<PMT> ->

0,”NO ERROR”<RMT>

• When You Wish to Return a Response without a Header

Responses that return both header and data can be set so that only the data section is returned. The “:COMMunicate:HEADer” command is used to do this.

• Abbreviated Form

Normally, the lower-case section 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.

3.4 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: The number of measurement samples

-> :SAMPle:GATE:EVENtsize 100)

<Voltage><Time> Physical value <Frequency> (Example: Gate time <Percentage> -> :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> Predefined character string (mnemonic).

Can be selected from { } (Example: Gate mode selection ->

:SAMPle:GATE:MODE {EVENt|TIME| EXTernal})

<Boolean> Indicates ON and OFF. Set to ON, OFF or

value (Example: Turn ON panorama display

-> :DISPlay:PANorama:STATe ON)

<Character string data> Arbitrary character string

(Example: Name of the file to be deleted

-> :FILE:DELete:SETup “SETUP_1”)

<Block data> Arbitrary 8-bit data

(Example: Response to acquired measured data -> #6000010ABCDEFGHIJ)

<Decimal> indicates a value expressed as a decimal number, as shown in the table below. Decimal values are given in the NR form as specified in the ANSI X3.42-1975.

Symbol Description Example

<NR1> Integer 125 -1 +1000 <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.

• The instrument can receive decimal values that are sent from the controller in any of the forms, <NR1> to <NR3>. This is represented by <NRf>.

• For response messages that the instrument returns to the controller, the form (<NR1> to <NR3> to be used) is determined by the query. The same form is used regardless of the size of the value.

• 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 a value has more significant digits than the available resolution, the value is rounded.

<Voltage>, <Time>, <Frequency>, and <Percent> indicate decimal values that have physical significance. Except for <Percent>, a <Multiplier> or <Unit> can be attached to <NRf>. They can be entered in any of the following forms.

Form Example

<NRf><Multiplier><Unit> 5MV <NRf><Unit> 5E-3V <NRf><Multiplier> 5M <NRf> 5E-3

•<Multiplier>

Multipliers which can be used are shown below.

Symbol Word Multiplier

EX Exa 10 PE Peta 10 T Tera 10 G Giga 10 MA Mega 10 K Kilo 10 MMilli 10 U Micro 10 N Nano 10 PPico 10 F Femto 10 A Ato 10

–3

–6

–9

–12

–15

–18

• <Unit>

Units which can be used are shown below.

Symbol Word Description

V Volt Voltage S Second Time HZ Hertz Frequency MHZ Megahertz Frequency PCT Percentage Percentage

• <Multiplier> and <Unit> are not case sensitive.

• “U” should be used in place of “µ” in the data.

• “MA” is used for Mega to distinguish it from Milli.

• If both <Multiplier> and <Unit> are omitted, the default unit is used.

• Response messages are always expressed in the <NR3> form. Response messages are returned using the default unit without the <Multiplier> or <Unit>.

Program Syntax and Programming

3-5IM 704510-17E

3.4 Data

<Register> indicates an integer, and can be expressed in hexadecimal, octal, or binary as well as a decimal number. <Register> is used when each bit of the value has a particular meaning. <Register> is expressed in one of the following forms.

Form Example

<NRf> 1 #H #H0F <Hexadecimal value made up of the digits 0 to 9 and A to F> #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> 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 Rules” on page 3-4.

<Character string data> is not a specified character string like <Character data>. It is an arbitrary character string. The character string must be enclosed in single quotation marks (‘) or double quotation marks (“).

Form Example

<Character string data> ‘ABC’ “IEEE488.2-1987”

• 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.

•A response message is always enclosed in double quotation marks (“).

• <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.

Form Example

{EVENt|TIME|EXTernal} EVENt

• As with the header, the “COMMunicate:VERBose” command can be used to select whether to return the response in the full form or in the abbreviated form.

• The “COMMunicate:HEADer” setting does not affect the <character data>.

<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

• When <Boolean> is expressed in the <NRf> form, “OFF” is selected if the rounded integer value is “0,” and ON for all other cases.

•A response message is always returned with a “1” if the value is ON and “0” if the value is OFF.

<Block data> is arbitrary 8-bit data. It is only used in response messages on the TA720 and is expressed in the following form.

Form Example

#8<8-digit decimal number> #800000010ABCDEFGHIJ <data byte sequence>

•#8 Indicates that the data is <Block data>.

• <8-digit decimal number> Indicates the number of bytes of data (example: 00000010 = 10 bytes).

• <data byte sequence> Expresses the actual data (example: 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.

3-6 IM 704510-17E

3.5 Synchronization with the Controller

The TA720 does not support overlap commands, which allows the execution of the next command to start before the execution of the previous command is completed. If multiple sequential commands are sent consecutively, the execution of the next command is held until the execution of the previous command is completed.

Achieving Synchronization

Synchronization is sometimes required for reasons other than communications-related reasons, such as the activation of a trigger, even if a sequential command is used. For example, if a “next program” message is transmitted to make an inquiry about the waveform data which has been acquired using single mode as the trigger mode, the “MEMory:SEND?” command is sometimes executed whether acquisition has been completed or not, causing a command execution error. :SSTart;:MEMory:SEND?<PMT> In this case, the following method must be used to synchronize with the end of the acquisition.

• Using the STATus:CONDition? query

The “STATus:CONDition?” query is used to query the contents of the condition register (page 5-4). It is possible to judge whether acquisition is in progress or not by reading bit 0 of the condition register. Bit 0 is “1” if acquisition is in progress, and “0” if acquisition is stopped.

Example :SSTart<PMT>

:STATus:CONDition?<PMT>

(Read the response. If bit 0 is 0, repeat this command until it becomes 1.)

:MEMory:SEND?<PMT>

The :MEMory:SEND? command will not be executed until bit 0 of the condition register is set to “1.”

• Using the extended event register

The changes in the condition register can be

reflected in the extended event register (page 5-4).

Example :STATus:FILTer1 RISE;:STATus:

EESE 1;EESR?;*SRE8;SSTart<PMT>

(Wait for a service request occurrence)

:MEMory:SEND?<PMT>

The “STATus:FILTer1 RISE” command sets the

transition filter so that bit 0 (FILTer1) of the extended event register is set to “1” when bit 0 of the condition register changes from “0” to “1.”

The “:STATus:EESE 1” command is used to

reflect only bit 0 of the extended event register to the status byte.

The “STATus:EESR?” command is used to clear

the extended event register.

The “*SRE” command is used to generate a service

request solely on the cause of the extended event register.

The “:MEMory:SEND?” command 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> (Read the response to STATus:EESR?) :COMMunicate:WAIT 1;:MEMory: SEND?<PMT>

For a description of “STATus:FILTer1 RISE” and

“STATus:EESR?” see the previous section regarding the extended event register.

The “COMMunicate:WAIT 1” command indicates

that the program will wait for bit 0 of the extended event register to be set to “1.”

The :MEMory:SEND? command will not be

executed until bit 0 of the extended event register is set to “1.”

Registers and Queues That Affect the Status Byte

Registers that affect the bits of the status byte are shown below.

Standard event register: Sets bit 5 (ESB) of the status byte to “1”

or “0.”

Output queue: Sets bit 4 (MAV) of the status byte to “1”

or “0.”

Extended event register: Sets bit 3 (EES) of the status byte to “1”

or “0.”

Error queue: Sets bit 2 (EAV) of the status byte to “1”

or “0.”

Enable Registers

Registers that are used to mask a bit so that the bit will not affect the status byte even when it is set to 1, are shown below.

Status byte: Mask the bits using the service request

enable register.

Standard event register: Mask the bits using the standard event

enable register.

Extended event register: Mask the bits using the extended event

enable register.

Writing/Reading from Registers

The *ESE command is used to set the bits in the standard event enable register to 1’s or 0’s. The *ESE? command is used to query whether the bits in the standard event enable register are 1’s or 0’s. For details regarding these commands, see chapter 4.

5.2 Status Byte

Overview of Status Byte

RQS

76ESBMAV EES EAV 1 0

MSS

• Bits 0, 1, and 7

Not used (always 0)

• Bit 2 EAV (Error Available)

Set to “1” when the error queue is not empty. In other words, this bit is set to “1” when an error occurs. See the page 5-5.

• Bit 3 EES (Extend Event Summary Bit)

Set to “1” when the logical product of the extended event register and the corresponding event register is “1.” —that is, when an event takes place inside the instrument. See the page 5-4.

• Bit 4 MAV (Message Available)

Set to “1” when the output queue is not empty. In other words, this bit is set to “1” when there are data to be transmitted. See the page 5-5.

• Bit 5 ESB (Event Summary Bit)

Set to “1” when the logical product of the standard event register and the corresponding event register is “1.” —that is, when an event takes place inside the instrument. See the page 5-3.

• Bit 6 RQS (Request Service)/MSS (Master Status Summary)

Set to “1” when the logical AND of the status byte excluding Bit 6 and the service request enable register is not “0.” In other words, this bit is set to “1” when the instrument is requesting service from the controller. RQS is set to “1” when the MSS bit changes from “0” to “1,” and cleared when serial polling is carried out or when the MSS bit changes to “0.”

Bit Masking

To mask a bit in the status byte so that it does not cause an SRQ, set the corresponding bit of the service request enable register to “0.” For example, to mask bit 2 (EAV) so that service is not requested when an error occurs, set bit 2 of the service request enable register to “0.” This can be done using the *SRE command. To query whether each bit of the service request enable register is “1” or “0,” use *SRE?. For details on the *SRE command, see chapter 4.

5-2 IM 704510-17E

5.2 Status Byte/5.3 Standard Event Register

Operation of the Status Byte

A service request is issued when bit 6 of the status byte becomes “1.” Bit 6 is set to “1” when any of the other bits becomes a “1” (when the corresponding bit of the service request enable register is also set to “1”). For example, if an event takes place and the logical OR of each bit of the standard event register and the corresponding bit in the enable register is “1,” bit 5 (ESB) will be set to “1.” In this case, if bit 5 of the service request enable register is “1,” bit 6 (MSS) will be set to “1,” thus requesting service from the controller. It is also possible to check what type of event has occurred by reading the contents of the status byte.

Reading from the Status Byte

The following two methods are provided for reading the status byte.

• Inquiry using the *STB? query

Making an inquiry using the *STB? query sets bit 6 to MSS. This causes the MSS to be read. After completion of the read-out, none of the bits in the status byte will be cleared.

• Serial polling

Execution of a serial polling changes bit 6 to RQS. This causes RQS to be read. After completion of the read-out, only RQS is cleared. Using a serial polling, it is not possible to read MSS.

Clearing the Status Byte

No method is provided for forcibly clearing all the bits in the status byte. The bits that are cleared for each operation are shown below.

• When an inquiry is made using the *STB? query

No bit is cleared.

• When a serial polling is executed

Only the RQS bit is cleared.

• When a *CLS command is received.

When the *CLS command is received, the status byte itself is not cleared, but the contents of the standard event register (which affects the bits in the status byte) are cleared. As a result, the corresponding bits in the status byte are cleared, except bit 4 (MAV), since the output queue cannot be emptied by the *CLS command. However, the output queue will also be cleared if the *CLS command is received just after a program message terminator.

5.3 Standard Event Register

• Bit 7 PON (Power ON)

• Bit 6 URQ (User Request)

• Bit 5 CME (Command Error)

• Bit 4 EXE (Execution Error)

• Bit 3 DDE (Device Dependent Error)

• Bit 2 QYE (Query Error)

• Bit 1 RQC (Request Control)

• Bit 0 OPC (Operation Complete)

Bit Masking

To mask a bit in the standard event register so that it does not cause bit 5 (ESB) of the status byte to change, set the corresponding bit in the standard event enable register to “0.” Refer to Chapter 4. For example, to mask bit 2 (QYE) so that ESB will not be set to “1,” even if a query error occurs, set bit 2 of the standard event enable register to “0.” This can be done using the *ESE command. To inquire whether each bit of the standard event enable register is “1” or “0,” use the *ESE?. For details on the *ESE command, see chapter 4.

CMEEXE DDEQYERQCOPC

Set to “1” when the power is turned ON.

Not used (always 0)

Set to “1” when the command syntax is incorrect.

Example Incorrectly spelled command name; “9”

used in octal data.

Set to “1” when the command syntax is correct but

the command cannot be executed in the current state.

Example Parameters are outside the range.

Set to “1” when execution of the command is not

possible due to an internal problem in the instrument that is not a command error or an execution error.

Set to “1” if the output queue is empty or if the data

is missing even after a query has been sent. Example No response data; data is lost due to an

overflow in the output queue.

Not used (always 0)

Set to “1” when the operation designated by the

*OPC command (see chapter 4) has been completed.

5.3 Standard Event Register/3.3 Responses

Operation of the Standard Event Register

The standard event register is provided for eight different kinds of event which can occur inside the instrument. Bit 5 (ESB) of the status byte is set to “1”

Reading from the Standard Event Register

The contents of the standard event register can be read by the *ESR command. After completion of the

read-out, the register will be cleared. when any of the bits in this register becomes “1” (or when the corresponding bit of the standard event enable register becomes “1”). Example

1. A query error occurs.

2. Bit 2 (QYE) is set to “1.”

3. Bit 5 (ESB) of the status byte is set to “1” if bit 2 of

the standard event enable register is “1.”

Clearing the Standard Event Register

The standard event register is cleared in the following

three cases.

• When the contents of the standard event register are read using the *ESR command.

• When a *CLS command is received.

• When the instrument is power cycled.

It is also possible to check what type of event has occurred inside the instrument by reading the contents of the standard event register.

5.4 Extended Event Register

Reading the extended event register tells you whether changes in the condition register (reflecting internal conditions) have occurred. A filter can be applied which allows you to decide which events are reported to the extended event register.

Bit 6 RTF(Rest Time Failure) Set to “1” when the pause time of block sampling falls short of 500 ns. Bit 7 NRC(No Reference Clock) Set to “1” when no reference signal is present. Bit 8 CMF(Continuation Measurement Failure) Set to “1” when continuous measurement fails. Bit 9 ISF(ISI analysis Failure) Set to “1” when inter-symbol interference analysis fails. Bit 10 NSP(No Sync Pattern) Set to “1” when simbol seach fails. Bit 11 Reserved Not used. Bit 12 CAL(CALibration) Set to “1” while calibration is in progress. Bit 13 TST(TeSTing) Set to “1” while self-test is in progress. Bit 14 ACS(file ACceSsing) Set to “1” while the storage medium is being accessed. Bit 15 HCP(Hard-CoPying) Set to “1” while hard copy is in progress.

The transition filter parameters detect changes in the specified bit (numerical suffix, 1 to 16) of the condition

RISE The bit of the extended event register becomes “1” when the bit of the condition register changes from “0” to “1.” FALL The bit of the extended event register becomes “1” when the bit of the condition register changes from “1” to “0.” BOTH The bit of the extended event register becomes “1” when the bit of the condition register changes from “0” to “1,” or from “1” to “0.” NEVer Always 0.
