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.

MEASure

SCALar

POWer

VOLTage

CURRent

:MEASure:SCALar:CURRent:DC?

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?

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 semi-colon (;) 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?

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.

Page 29

Long form

:STATus:OPERation:NTRansition? :STATUS:OPERATION:NTRANSITION? :status:operation:ntransition?

Short form

: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. Both ":DISPlay:MENU[:NAME]?" and ":DISPlay:MENU?" are both valid forms.

5-1. 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 PFR-100 Series have a number of register groups:

 Questionable Status Register Group  Standard Event Status Register Group  Operation Status Register Group  Status Byte Register Group  Service Request Enable Register Group  Service Request Generation  Error Query  Output Buffer

The following page shows the configuration of the Status Register.

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 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.

Enable Register

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

5-7. Error list

5-7-1. 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 device-specific 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.

Page 76

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?:MEAS:CURR: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 white space followed the header, thus *SRE2 is an error.

-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.

Page 77

-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.

-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.

5-7-2. 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.

Page 78

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.

-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 cannot 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.).

-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

This parameter can not be specified.

Page 79

5-7-3. 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 device-specific 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, 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.

5-7-4. 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;

Events that generate query errors shall not generate command errors, execution errors, or device-specific errors; see the other error

Page 80

definitions in this section.

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.
