Safety precautions

The following safety precautions should be observed before using this product and any associated instrumentation. Although some instruments and accessories would normally be used with nonhazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument. They must be protected from electric shock and contact with hazardous live circuits.

Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that are measurement, control, and data I/O connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high transient overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be marked as category II or higher.

Unless explicitly allowed in the specifications, operating manual, and instrument labels, do not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000 V, no conductive part of the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided in close proximity to the equipment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.

For safety, instruments and accessories must be used in accordance with the operating instructions. If the instruments or accessories are used in a manner not specified in the operating instructions, the protection provided by the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories. Maximum signal levels are defined in the specifications and operating information and shown on the instrument panels, test fixture panels, and switching cards.

When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard.

Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety ground) connections.

If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid interlock.

If a screw is present, connect it to protective earth (safety ground) using the wire recommended in the user documentation.

The symbol on an instrument means caution, risk of hazard. The user must refer to the operating instructions located in the user documentation in all cases where the symbol is marked on the instrument.

The symbol on an instrument means warning, risk of electric shock. Use standard safety precautions to avoid personal contact with these voltages.

The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.

The symbol indicates a connection terminal to the equipment frame.

If this symbol is on a product, it indicates that mercury is present in the display lamp. Please note that the lamp must be properly disposed of according to federal, state, and local laws.

The WARNING heading in the user documentation explains hazards that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the warranty.

The CAUTION heading with the symbol in the user documentation explains hazards that could result in moderate or minor injury or damage the instrument. Always read the associated information very carefully before performing the indicated procedure. Damage to the instrument may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and all test cables.

To maintain protection from electric shock and fire, replacement components in mains circuits — including the power transformer, test leads, and input jacks — must be purchased from Keithley. Standard fuses with applicable national safety approvals may be used if the rating and type are the same. The detachable mains power cord provided with the instrument may only be replaced with a similarly rated power cord. Other components that are not safety-related may be purchased from other suppliers as long as they are equivalent to the original component (note that selected parts should be purchased only through Keithley to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley office for information.

Unless otherwise noted in product-specific literature, Keithley instruments are designed to operate indoors only, in the following environment: Altitude at or below 2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution degree 1 or 2.

To clean an instrument, use a cloth dampened with deionized water or mild, water-based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

For example, if channel 1 and channel 2 are both set to 1 V when tracking is turned on, a one-to-one ratio is maintained and any voltage change on channel 1 results in a corresponding change on channel 2. If channel 1 is set to 10 V and channel 2 is set to 5 V when tracking is turned on, a two to one ratio is maintained and any voltage change on channel 1 results in a voltage change of half the size of channel 2.

Standard Commands for Programmable Instruments

Standard Commands for Programmable Instruments (SCPI) is a standard programming language for controlling instrument functions over USB connections. SCPI programming language acts as an interface for the hardware-portion of the IEEE 488-2 standard. The SCPI commands and parameters can be used to control different classes of instruments using the same code.

This section is an overview of how SCPI commands are constructed and how they are used with the Series 2230.

Detailed command descriptions are available in the SCPI command reference (on page 5-1

There are two types of commands you can use when communicating remotely with the Series 2230: Common commands and Standard Commands for Programmable Instruments (SCPI) subsystem commands.

• Common commands: These commands are not usually related to specific operation, but to

ontrolling the instrument overall. Example functions are instrument reset, status,

synchronization.

All common commands consist of a three-letter mnemonic preceded by an asterisk:

*RST *IDN? *SRE 8.

Types of SCPI messages

There are two types of SCPI messages:

• Program messages: A program message consists of one or more properly formatted SCPI

commands sent from the controller to the power supply. The message, which may be sent at any time, instructs the power supply to perform some action.

• Response message: A response message consists of data in a specific SCPI format sent from

he power supply to the controller. The power supply sends the message only when commanded

by a program message called a "query."

Command execution rules

The following are a few basic rules of SCPI command execution:

• Commands execute in the order that they are presented in the command message.

• An invalid command generates an error message and is not executed.

• Valid commands that precede an invalid command in a multiple command message are

• Valid commands that follow an invalid command in a multiple command message are ignored.

Case sensitivity

Common commands and SCPI commands are not case sensitive. You can use uppercase or lowercase characters, as shown in the following examples:

Introduction to SCPI

The message unit

The simplest SCPI command is a single message unit consisting of a command header (or keywords) followed by a message terminator. The message unit may include a parameter after the header. The parameter can be numeric or a string. For example:

VOLTage 20<NL>

The following topics describe the parts of a SCPI command message in more detail.

Headers

Headers, also referred to as keywords, are instructions recognized by the power supply. Headers may be either in the long form or the short form.

In the long form, the header is completely spelled out, such as VOLTage, STATus, and DELay.

In the short form, the header has only the first three or four letters. Examples of four-letter short form commands are VOLT and STAT. If the fourth letter of the long form is a vowel (for example, DELete)

he short form only contains three letters (DEL).

Queries

You can use a query to determine the present value of the parameters of the command or to get information from the instrument. Following a header with a question mark turns it into a query, for example:

VOLTage?

VOLTage:PROTection?

If a query contains a parameter, place the query indicator at the end of the last header, for example:

VOLTage:PROTection? MAX

Observe the following precautions with queries:

• Set up the proper number of variables for the returned data. For example, if you are reading back

a measurement array, you must dimension the array according to the number of measurements that you have placed in the measurement buffer.

• Read back all the results of a query before sending another command to the power supply. If you

send another command before the results of a query have been returned, an error message, Query Interrupted is generated and the unreturned data is lost.

When two or more message units are combined into a compound message, separate the units with a semicolon (;), for example:

Root specifier

When it precedes the first header of a message unit, the colon becomes the root specifier, as shown in the following figure. It tells the command parser that this is the root or the top node of the command tree.

Multiple commands in a message

You can group multiple SCPI command messages and send them as a single message with one message terminator. There are two important considerations when sending several commands in a single message.

• Separate each command with a semicolon (;)

• Header paths influence how the instrument interprets commands

The header path is a string that is inserted in front of every command in a message. The header path in the first command message is a null string. For each subsequent command with the same header path, the header is implied. For example:

CURR:LEV 3; PROT:STAT OFF

In the example above, the header path is CURR. Because the two commands are separated with

emicolon (;) and the commands are in the same header path, the header path CURR is not neede

or the second command. The instrument automatically interprets the command following the

f semicolon as:

CURR:PROT:STAT OFF

If CURR is explicitly included in the second command in the first example above, it is semantically

wrong. The instrument will interpret the second command as CURR:CURR:PROT:STAT OFF, and

ror will occur.

Movement in the subsystem

To combine commands from different subsystems, you must reset the header path to a null string. To do this, begin the command with a colon (:). This discards any previous header path. For example, t

lear the output protection and check the status of the Operation Condition Register in a single

message, use a root specifier as follows:

PROTection:CLEAr;:STATus:OPERation:CONDition?

The following example message shows how to combine commands from different subsystems and within the same subsystem:

POWer:LEVel 200; PROTection 28; :CURRent:LEVel 3; PROTection:STATe ON

Note the use of the optional LEVel header to maintain the correct path within the voltage and current

subsystems, and the use of the root specifier to move between subsystems.

You can combine common commands with subsystem commands in the same message. Treat the common command as a message unit by separating it with a semicolon (the message unit separator). Common commands do not affect the header path; you may insert them anywhere in the message.

Examples:

VOLT 5.0; :*OPC?;OUTP ON

SCPI data formats

All data programmed to or returned from the power supply is ASCII. The data may be numerical or it can be a character string. The following topics provide more details about SCPI data formats.

Talking and listening data formats

There are talking data formats and listening data formats. The following tables define the differences.

Response messages

A response message is the message sent by the instrument to the computer in response to a query command.

Response data types

Character strings returned by query statements may take any of the following formats, depending on the length of the returned string.

Symbol Description

Getting a response message

After sending a query command, the response message is placed in the output queue. When the Series 2230 is then addressed to talk, the response message is sent from the output queue to the computer.

Triple-Channel Power Supplies User's Manual Section 4:

Introduction to SCPI

Multiple response messages

If you send more than one query command in the same program message (see Multiple commands

in a message (on page 4-8)), multiple response messages are sent to the computer when the Series

2230 is addressed to talk. The responses are separated with semicolons (;) and are sent in the order

that the query commands were sent. Items within the same query are separated by commas (,).

The following example shows the response message for a program message that contains four single-item query commands:

0; 1; 1; 0

Response message terminator (RMT)

Each response is terminated with an LF (line feed) and EOI (end or identify). The following example

shows how a multiple response message is terminated:

0; 1; 1; 0; <RMT>

Message exchange protocol

The following items summarize the message exchange protocol:

• You must always tell the Series 2230 what to send to the computer.

The following steps must always be performed to send information from the instrument to a computer:

1. Send the appropriate query commands in a program message.

2. Address the Series 2230 to talk.

• The complete response message must be received by the computer before another program

sage can be sent to the Series 2230.

4: Introduction to SCPI Series 2230 Triple-Channel Power Supplies

User's Manual

SCPI command completion

SCPI commands sent to the power supply are processed either sequentially or in parallel. Sequential commands finish execution before a subsequent command begins. Parallel commands allow other commands to begin executing while the parallel command is still executing. Commands that affect trigger actions are among the parallel commands.

The *WAI, *OPC?, and *OPC common commands provide different ways of indicating when all

transmitted commands, including any parallel ones, have completed their operations. Some practical considerations for using these commands are:

• *WAI: This command prevents the power supply from processing subsequent commands until all

pending operations are completed.

• *OPC?: This command places a 1 in the output queue when all pending operations have

ompleted. Because it requires your program to read the returned value before executing the next

c program statement, the *OPC? command can be used to cause the controller to wait for

commands to complete before proceeding with its program.

• *OPC: This sets the operation complete (OPC) status bit when all pending operations have

ompleted. Since your program can read this status bit on an interrupt basis, the *OPC comma

allows subsequent commands to be executed.

he trigger system must be in the idle state for the status OPC bit to be true; OPC is false whenever

the t

rigger system is in the initiated state.

Using device clear

You can send a device clear command at any time to abort a SCPI command. The status registers, error queue, and all configuration states are left unchanged when a device clear message is received. Device clear performs the following actions:

• Clears the input and output buffers of the power supply.

• Prepares the power supply to accept a new command string.

You must use the SYSTem:

programming commands.

Common commands

Common commands begin with an asterisk (*) and consist of three letters (command form) or three

letters and a question mark (?) (query form). They are defined by the IEEE 488.2 standard to perform

common interface functions.

The Series 2230 responds to the required common commands that control status reporting, synchronization, and internal operations. The Series 2230 also responds to optional common commands that control triggers, power-on conditions, and stored operating parameters.

If a command has a corresponding query that returns the data or status specified by the command, both command and query formats are included under the explanation for the command.
