Selecting the address

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

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.

1-6 IM 704310-12E

1.5 Responses to Interface Messages

Response to Interface Message

Response to a uni-line message

• IFC (Interface Clear) Clears the talker and listener. Stops output if data is being output.

• REN (Remote Enable) Switches between remote and local modes.

• IDY (Identify) is not supported.

Responses to a multi-line message (address command)

• GTL (Go To Local) Switches to local mode.

• SDC (Selected Device Clear) Clears the program message (command) which is currently being output. Also empties the output queue (page 4-5).

• GET (Group Execute Trigger) Same as *TRG.

•

COMMunicate:WAIT will be stopped immediately.

• PPC (Parallel Poll Configure) and TCT (Take Control) are not supported.

Responses to a multi-line message (universal command)

• LLO (Local Lockout) Invalidates the LOCAL key on the front panel, disabling switching to local mode.

• DCL (Device Clear) Same as SDC.

• SPE (Serial Poll Enable) Sets the talker function to serial poll mode for all equipment connected to the communications bus. The controller polls equipment sequentially.

• SPD (Serial Poll Disable) Clears serial poll mode as the talker function for all equipment connected to the communications bus.

• PPU (Parallel Poll Unconfigure) is not supported.

Chapter 2 Before Programming

<Program data>Space

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 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.

A program header is used to indicate the command type. For details, refer to page 2-3.

Before Programming

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

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.

Example

:SAMPLE:GATE:MODE EVENT<PMT>

Header

Data

2-1IM 704310-12E

2.1 Messages

Response Messages

The data returned by this instrument to the controller is called a response message. The format of a response message is shown below.

;

<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>

Unit Unit

<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

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 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 IM 704310-12E

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.

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.

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.

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.

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> 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.

2-5IM 704310-12E

2.4 Data

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

• <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

" 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> 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> 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> 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

"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>

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

"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

"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].

Registers and Queues which Affect the Status Byte

Registers which affect each bit of the status byte are shown below.

Standard event register : Sets bit 5 (ESB) of status byte to [1] or [0]. Output queue : Sets bit 4 (MAV) of status byte to [1] or [0]. Extended event register : Sets bit 3 (EES) of status byte to [1] or [0]. Error queue : Sets bit 2 (EAV) of status byte to [1] or [0].

Enable Registers

Registers which mask a bit so that the bit does not affect the status byte, even if the bit is set to [1], are shown below.

Status byte : Masks bits using the service request enable register. Standard event register : Masks bits using the standard event enable register. Extended event register : Masks bits using the extended event enable register.

Writing/Reading from Registers

The

*ESE command is used to set bits in the standard

event enable register to [ 1] or [0], and the

*ESR? query

is used to check whether bits in that register are set to [1] or [ 0]. For details of these commands, refer to Chapter 3.

Bit 2 EAV (Error Available)

Set to [1] when the error queue is not empty, i.e. when an error occurs. For details, refer to page 4-5.

Bit 3 EES (Extended Event Summary Bit)

Set to [1] when a logical AND of the extended event register and the corresponding enable register is [1], i.e. when an event takes place in the instrument. Refer to page 4-4.

Bit 4 MAV (Message Available)

Set to "1" when the output queue is not empty, i.e. when there is data which is to be output when an inquiry is made. Refer to page 4-5.

Bit 5 ESB (Event Summary Bit)

Set to "1" when a logical AND of the standard event register and the corresponding enable register is [1], i.e. when an event takes place in the instrument. Refer to page 4-3.

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

Status)

MSS is set to [1] when a logical AND of the status byte (except for bit 6) and the service request enable register is not [0], i.e. when the instrument is requesting service from the controller. RQS is set to [1] when MSS changes from [0] to [1], and is cleared when a serial poll is performed or when MSS 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 For example, to mask bit 2 (EAV) so that no service will be requested, even if 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 of the *SRE command, refer to Chapter 3.

4-2 IM 704310-12E

4.2 Status Byte/4.3 Standard Event Register

Operation of the Status Byte

A service request is issued when bit 6 of the status byte becomes [1]. Bit 6 becomes [1] when any of the other bits becomes [1] (or when the corresponding bit in the service request enable register becomes [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 poll

Execution of a serial poll changes bit 6 to RQS. This causes RQS to be read. After completion of the read-out, only RQS is cleared. Using a serial poll, 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. Bits which are cleared are shown below.

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

No bit is cleared.

• When a serial poll is performed

Only the RQS bit is cleared.

• When the *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.

Bit 0 OPC (Operation Complete)

Set to "1" when the operation designated by the *OPC command has been completed. Refer to Chapter 3.

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". 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 of the *ESE command,

4.3 Standard Event Register/4.4 Extended Event Register

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

ïThe 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]). Examples

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

*ESR?

• When the *CLS command is received

• When power is turned ON again

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

Bit 2 Tov (Time Stamp Overflow) Set to "1" when time stamp data overflows. Bit 3 SOV (Sample Overflow) Set to "1" when the number of measured samples is exceeded. Bit 4 MTF (Measured T Failure) Set to "1" when the measurement of Measured T fails. Bit 5 ETF (Estimated T Failure) Set to "1" when the measurement of Estimated T fails. Bit 6 RTF (Rest Time Failure) Set to "1" when the pause time of block sampling is less than 500 ns. Bit 8 CAL (Calibration) Set to "1" during calibration. Bit 9 TST (Testing) Set to "1" during self-test. Bit 10 ACS (Accessing) Set to "1" while accessing the medium. Bit 11 HCP (Hard-Copying) Set to "1" during the hard copy operation. Bit 12 INI (Initializing) Set to "1" during initialization. Bit 13 ASC (Auto Scaling) Set to "1" during auto scaling.

The transition filter parameters determine change of each bit (suffix 1 to 16) in the condition register and set the corresponding bit of the extended event register as shown below.

RISE Sets the extended event register bit to [1] when the condition register bit changes from [0] to [1]. FALL Sets the extended event register bit to [1] when the condition register bit changes from [1] to [0]. BOTH Sets the extended event register bit to [1] when the condition register bit changes from [0] to [1] or from [1] to [0]. NEVer The extended event register bit is fixed at [0].

4.5 Output Queue and Error Queue

Overview of the Output Queue

The output queue is provided to store response messages to queries. For example, when the

WAVeform:SEND? query is sent to request output of the

acquired waveform, the response data will be stored in the output queue until it is read out. The example below shows that data is stored record by record in the output queue, and is read out oldest item first, newest item last. The output queue is emptied in the following cases (in addition to when read-out is performed).

• When a new message is received from the controller

• When dead lock occurs (page 2-2)

• When a device clear command (DCL or SDC) is received

• When power is turned ON again

The output queue cannot be emptied using the command. To see whether the output queue is empty or not, check bit 4 (MAV) of the status byte.

*CLS

4.5 Output Queue and Error Queue

Status Report

Overview of the Error Queue

The error queue stores the error No. and message when an error occurs. For example, when the built-in battery has run out, an error occurs and its error No. (901) and message "Backup Failure " will be stored in the error queue. The contents of the error queue can be read using the

STATus:ERRor? query. As with the output queue,

messages are read oldest first, newest last (refer to the previous page). If the error queue becomes full, the final message will be replaced by message 350, "Queue overflow ". The error queue is emptied in the following cases (in addition to when read-out is performed).

• When the
