SAFETY INSTRUCTIONS

Power cord for the United Kingdom

When using the instrument in the United Kingdom, make sure the power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow:

Blue:

Brown:

Earth

Neutral

Live (Phase)

As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol

or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the supplier.

This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm

2

should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

Command Syntax

Compatible

Standard

Command

Structure

IEEE488.2

SCPI, 1999

Partial compatibility

Partial compatibility

SCPI commands follow a tree-like structure, organized into nodes. Each level of the command tree is a node. Each keyword in a

SCPI command represents each node in the command tree. Each keyword (node) of a SCPI command is separated by a colon (:).

For example, the diagram below shows an SCPI sub-structure and a command example.

Command types

There are a number of different instrument commands and queries. A command sends instructions or data to the unit and a query receives data or status information from the unit.

Command types

Simple

Example

A single command with/without a parameter

*IDN?

48

Query

Example

Compound

Example

REMOTE CONTROL

A query is a simple or compound command followed by a question mark

(?). A parameter (data) is returned. meas:curr:dc?

Two or more commands on the same command line.

Compound commands are separated with either a semicolon (;) or a semi-colon and a colon (;:).

A semi-colon is used to join two related commands, with the caveat that the last command must begin at the last node of the first command.

A semi-colon and colon are used to combine two commands from different nodes. meas:volt:dc?;:meas:curr:dc?

49


Command Forms

Commands and queries have two different forms, long and short. The command syntax is written with the short form of the command in capitals and the remainder (long form) in lower case.

The commands can be written in capitals or lower-case, just so long as the short or long forms are complete. An incomplete command will not be recognized.

Below are examples of correctly written commands.

Long form

Short form

STATus:OPERation:NTRansition?

STATUS:OPERATION:NTRANSITION? status:operation:ntransition?

STAT:OPER:NTR? stat:oper:ntr?

Square Brackets

Commands that contain square brackets indicate that the contents are optional. The function of the command is the same with or without the square bracketed items, as shown below.

For the DISPlay[:WINDow][:STATe] command, both “DISPlay:WINDow:STATe?” and

“DISPlay?” are valid forms.

The Questionable Status Condition Register indicates the status of the power supply. If a bit is set in the Condition register, it indicates that the event is true. Reading the condition register does not change the state of the condition register.

PTR/NTR Filters

The PTR/NTR (Positive/Negative transition) register determines the type of transition conditions that will set the corresponding bit in the Event Registers. Use the Positive transition filter to view events that change from false to positive, and use the negative transition filter to view events that change from positive to negative.

Positive Transition

Negative Transition

0→1

1→0

Event Register

The PTR/NTR Register will dictate the type of transition conditions will set the corresponding bits in the Event Register. If the Event Register is read, it will be cleared to 0.

The Enable register determines which Events in the Event Register will be used to set the QUES bit in the Status Byte Register.

The Operation Status Condition Register indicates the operating status of the power supply. If a bit is set in the Condition register, it indicates that the event is true. Reading the condition register does not change the state of the condition register.

PTR/NTR Filters

The PTR/NTR (Positive/Negative transition) register determines the type of transition conditions that will set the corresponding bit in the Event Registers. Use the Positive transition filter to view events that change from false to positive, and use the negative transition filter to view events that change from positive to negative.

Command Errors

Overview

An <error/event number> in the range [ -199 , -

100 ] indicates that an IEEE 488.2 syntax error has been detected by the instrument’s parser.

The occurrence of any error in this class shall cause the command error bit (bit 5) in the event status register (IEEE 488.2, section 11.5.1) to be set. One of the following events has occurred:



An IEEE 488.2 syntax error has been detected by the parser. That is, a controller-to-device message was received which is in violation of the IEEE 488.2 standard. Possible violations include a data element which violates the device listening formats or whose type is unacceptable to the device.



An unrecognized header was received.

Unrecognized headers include incorrect devicespecific headers and incorrect or unimplemented IEEE 488.2 common commands.

Events that generate command errors shall not generate execution errors, device-specific errors, or query errors; see the other error definitions in this chapter.

Error Code

-100 Command

Error

-102 Syntax error

-103 Invalid separator

-104 Data type error

-108 Parameter not allowed

-109 Missing parameter

-111 Header separator error

Description

This is the generic syntax error for devices that cannot detect more specific errors. This code indicates only that a Command Error as defined in IEEE 488.2,11.5.1.1.4 has occurred.

An unrecognized command or data type was encountered; for example, a string was received when the device does not accept strings.

The parser was expecting a separator and encountered an illegal character; for example, the semicolon was omitted after a program message unit,

MEAS:VOLT:DC?:MEASCURR:DC?

The parser recognized a data element different than one allowed; for example, numeric or string data was expected but block data was encountered.

More parameters were received than expected for the header; for example, the KLOCk command only accepts one parameter, so receiving SYSTem:KLOCk 1,0 is not allowed.

Fewer parameters were recieved than required for the header; for example, the KLOCk command requires one parameter, so receiving

KLOCk is not allowed.

A character which is not a legal header separator was encountered while parsing the header; for example, no white space followed the header, thus APPL5,1 is an error.

118

REMOTE CONTROL

-112 Program mnemonic too long

-113 Undefined header

-114 Header suffix out of range

-115 Unexpected number of parameters

-120 Numeric data error

-121 Invalid character in number

The header contains more that twelve characters (see IEEE 488.2, 7.6.1.4.1).

The header is syntactically correct, but it is undefined for this specific device; for example,

*XYZ is not defined for any device.

The value of a numeric suffix attached to a program mnemonic, see Syntax and Style section 6.2.5.2, makes the header invalid.

The number of parameters received does not correspond to the number of parameters expected. This is typically due an inconsistency with the number of instruments in the selected group.

This error, as well as errors -121 through -129, are generated when parsing a data element which apprears to be numeric, including the nondecimal numeric types. This particular error message should be used if the device cannot detect a more specific error.

An invalid character for the data type being parsed was encountered; for example, an alpha in a decimal numeric or a “9" in octal data.

-128 Numeric data not allowed

A legal numeric data element was received, but the device does not accept one in this position for the header.

-131 Invalid suffix

The suffix does not follow the syntax described in IEEE 488.2, 7.7.3.2, or the suffix is inappropriate for this device.

119


-141 Invalid character data

-148 Character data not allowed

-151 Invalid string data

-158 String data not allowed

-160 Block data error

-161 Invalid block data

-168 Block data not allowed

-178 Expression data not allowed

Either the character data element contains an invalid character or the particular element received is not valid for the header.

A legal character data element was encountered where prohibited by the device.

A string data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.5.2); for example, an END message was received before the terminal quote character.

A string data element was encountered but was not allowed by the device at this point in parsing.

This error, as well as errors -161 through -169, are generated when parsing a block data element. This particular error message should be used if the device cannot detect a more specific error.

A block data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.6.2); for example, an END message was received before the length was satisfied.

A legal block data element was encountered but was not allowed by the device at this point in parsing.

A legal expression data was encountered but was not allowed by the device at this point in parsing.

120

REMOTE CONTROL

Execution Errors

Overview An <error/event number> in the range [ -299 , -

200 ] indicates that an error has been detected by the instrument’s execution control block.

The occurrence of any error in this class shall cause the execution error bit (bit 4) in the event status register (IEEE 488.2, section 11.5.1) to be set. One of the following events has occurred:



A <PROGRAM DATA> element following a header was evaluated by the device as outside of its legal input range or is otherwise inconsistent with the device’s capabilities.



A valid program message could not be properly executed due to some device condition.

Execution errors shall be reported by the device after rounding and expression evaluation operations have taken place. Rounding a numeric data element, for example, shall not be reported as an execution error. Events that generate execution errors shall not generate

Command Errors, device-specific errors, or

Query Errors; see the other error definitions in this section.

Error Code

-200 Execution error

Description

This is the generic syntax error for devices that cannot detect more specific errors. This code indicates only that an Execution Error as defined in IEEE 488.2, 11.5.1.1.5 has occurred.

121


-201 Invalid while in local

-203 Command protected

-211 Trigger ignored

-213 Init ignored

-220 Parameter error

-221 Settings conflict

Indicates that a command is not executable while the device is in local due to a hard local control (see IEEE 488.2, 5.6.1.5); for example, a device with a rotary switch receives a message which would change the switches state, but the device is in local so the message can not be executed.

Indicates that a legal password-protected program command or query could not be executed because the command was disabled.

Indicates that a GET, *TRG, or triggering signal was received and recognized by the device but was ignored because of device timing considerations; for example, the device was not ready to respond. Note: a DT0 device always ignores GET and treats *TRG as a Command

Error.

Indicates that a request for a measurement initiation was ignored as another measurement was already in progress.

Indicates that a program data element related error occurred. This error message should be used when the device cannot detect the more specific errors described for errors -221 through

-229.

Indicates that a legal program data element was parsed but could not be executed due to the current device state (see IEEE 488.2, 6.4.5.3 and

11.5.1.1.5.).

122

REMOTE CONTROL

-222 Data out of range

-224 Illegal parameter value

Indicates that a legal program data element was parsed but could not be executed because the interpreted value was outside the legal range as defined by the device (see IEEE 488.2,

11.5.1.1.5.).

Used where exact value, from a list of possibles, was expected.

Device Specific Errors


300 ] or [ 1 , 32767 ] indicates that the instrument has detected an error which is not a command error, a query error, or an execution error; some device operations did not properly complete, possibly due to an abnormal hardware or firmware condition. These codes are also used for self-test response errors. The occurrence of any error in this class should cause the device-specific error bit (bit 3) in the event status register (IEEE 488.2, section 11.5.1) to be set. The meaning of positive error codes is device-dependent and may be enumerated or bit mapped; the <error message>string for positive error codes is not defined by SCPI and available to the device designer.

Note that the string is not optional; if the designer does not wish to implement a string for a particular error, the null string should be sent (for example, 42,""). The occurrence of any error in this class should cause the devicespecific error bit (bit 3) in the event status register (IEEE 488.2, section 11.5.1) to be set.

Events that generate device-specific errors shall not generate command errors, execution errors,

123


or query errors; see the other error definitions in this section.

Error Code Description

-310 System error

Indicates that some error, termed “system error” by the device, has occurred. This code is device-dependent.

-320 Storage fault

Indicates that the firmware detected a fault when using data storage. This error is not an indication of physical damage or failure of any mass storage element.

Query Errors


400 ] indicates that the output queue control of the instrument has detected a problem with the message exchange protocol described in IEEE

488.2, chapter 6. The occurrence of any error in this class shall cause the query error bit (bit 2) in the event status register (IEEE 488.2, section

11.5.1) to be set. These errors correspond to message exchange protocol errors described in

IEEE 488.2, section 6.5. One of the following is true:



An attempt is being made to read data from the output queue when no output is either present or pending;



Data in the output queue has been lost.

Events that generate query errors shall not generate command errors, execution errors, or device-specific errors; see the other error definitions in this section.

124

REMOTE CONTROL

Error Code

-400 Query error

Description

This is the generic query error for devices that cannot detect more specific errors. This code indicates only that a Query Error as defined in
