Safety Guidelines

General Guideline

CAUTION

• Do not place any heavy object on the

instrument.

• Avoid severe impact or rough handling that

leads to damaging the instrument.

• Do not discharge static electricity to the

instrument.

• Use only mating connectors, not bare wires, for

the terminals.

• Do not block the cooling fan opening.

• Do not disassemble the instrument unless you

are qualified.

(Measurement categories) EN 61010-1:2001 specifies the measurement categories and their requirements as follows. This instrument falls under category II.

• Measurement category IV is for measurement performed at the source of low-voltage installation.

• Measurement category III is for measurement performed in the building installation.

• Measurement category II is for measurement performed on the circuits directly connected to the low voltage installation.

• Measurement category I is for measurements performed on circuits not directly connected to Mains.

Power Supply

WARNING

• AC Input voltage range: 85VAC~265VAC

• Frequency: 47Hz~63Hz

• To avoid electrical shock connect the protective

grounding conductor of the AC power cord to an earth ground.

2260B Series Programming Manual

Cleaning the Instrument

• Disconnect the power cord before cleaning.

• Use a soft cloth dampened in a solution of mild

detergent and water. Do not spray any liquid.

• Do not use chemicals containing harsh material

such as benzene, toluene, xylene, and acetone.

Operation Environment

• Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

• Relative Humidity: 20%~ 85%

• Altitude: < 2000m

• Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. The Instrument falls under degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.

• Pollution degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.

• Pollution degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

• Pollution degree 3: Conductive pollution occurs, or dry, non- conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

• Relative Humidity: <90%

Disposal

Do not dispose this instrument as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Please make sure discarded electrical waste is properly recycled to reduce environmental impact.

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: Earth Blue: Neutral Brown: 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

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

IEEE488.2

Partial compatibility

SCPI, 1999

Partial compatibility

Command Structure

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

A single command with/without a parameter

Example

*IDN?

REMOTE CONTROL

Query

A query is a simple or compound command followed by a question mark (?). A parameter (data) is returned.

Example

meas:curr:dc?

Compound

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.

Example

meas:volt:dc?;:meas:curr:dc?

2260B Series Programming Manual

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.

Introduction to the Status Registers

Overview

The status registers are used to determine the status of the power supply. The status registers maintain the status of the protection conditions, operation conditions and instrument errors.

The 2260B Series have a number of register groups:

• Questionable Status Register Group

• Standard Event Status Register Group

• Operation Status Register Group

• Status Byte Register

• Service Request Enable Register

• Service Request Generation

• Error Queue

• Output Buffer

The next page shows the structure of the Status registers.

Condition Register

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

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.

2260B Series Programming Manual

Error Code Description

-100 Command Error

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.

-102 Syntax error

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

-103 Invalid separator

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?

-104 Data type error

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

-108 Parameter not allowed

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.

-109 Missing parameter

Fewer parameters were received than required for the header; for example, the KLOCk command requires one parameter, so receiving KLOCk is not allowed.

-111 Header separator error

A character which is not a legal header separator was encountered while parsing the header; for example, no blank space followed the header, thus APPL 5, 1 is an error.

REMOTE CONTROL

-112 Program mnemonic too long

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

-113 Undefined header

The header is syntactically correct, but it is undefined for this specific device; for example, *XYZ is not defined for any device.

-114 Header suffix out of range

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

-115 Unexpected number of parameters

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.

-120 Numeric data error

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

-121 Invalid character in number

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.

2260B Series Programming Manual

-141 Invalid character data

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

-148 Character data not allowed

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

-151 Invalid string data

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.

-158 String data not allowed

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

-160 Block data error

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.

-161 Invalid block data

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.

-168 Block data not allowed

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

-178 Expression data not allowed

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

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 Description

-200 Execution error

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.

2260B Series Programming Manual

-201 Invalid while in local

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.

-203 Command protected

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

-211 Trigger ignored

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.

-213 Init ignored

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

-220 Parameter error

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.

-221 Settings conflict

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.).

REMOTE CONTROL

-222 Data out of range

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.).

-224 Illegal parameter value

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

Device Specific Errors

Overview

An <error/event number> in the range [ -399 , 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,

2260B Series Programming Manual

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

Overview

An <error/event number> in the range [ -499 , 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.

REMOTE CONTROL

Error Code Description

-400 Query error

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 IEEE 488.2, 11.5.1.1.7 and 6.3 has occurred.
