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 prec autions 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 pr oduct 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 t hat the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.

Operators use the product for its i ntended function. They must be traine d 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, s etting 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 cir c ui ts, perform safe installations, and repair products. Only properl y trained service personnel may perform ins tallation and service procedures.

Keithley products are designed f or use with electrical signals that are measurement, control, and data I/O connections, with low transient overvoltages, and mus t not be directly connected to mains v oltage or to voltage sources with high transient overvoltages. Measurement Cat egory II (as referenced in IEC 60664) c onnections require protect ion for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be mar k ed as category II or higher.

Unless explicitly allowed in the spec i fications, operating manual, and ins trument 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 S tandards Institute (ANSI) stat es 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 v oltage is present in any unknown circuit before measuring.

Operators of this product must be protec ted 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 i n these circumstances must be trained t o 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 direc tly to unlimited power circuits. T hey are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching car ds , install protective devices to limit fault current and v ol tage 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 j umpers for possible wear, cracks, or breaks before each use.

When installing equipment where ac cess 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 in s truments while power is applied to the c i r cuit under test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or dis connecting cables or jumpers, installing or rem oving 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 (ear th) 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 ins truments or accessories are used in a manner not s pecified in the operating instructions, the protection provided b y t he equipment may be impaired.

Do not exceed the maximum signal lev els of the instruments and accessori es. Maximum signal levels are defined i n the specifications and operating inf or mation and shown on the instrument panels, test fixture panels, an d switching cards.

When fuses are used in a product, replac e with the same type and rating for contin ued protection against fire hazard. Chassis connections must only be used as shield connections for meas uring 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.

properly disposed of according to federal, state, and local laws. The WARNING heading in the user documentation explains hazards that might result in personal inj ury or death. Always read

the associated information very car efully 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 moder ate or minor injury or damage the instrument. Always read the associated information v ery carefully before performing t he 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 j ac ks — 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 instrum ent 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 equival ent to the original component (note that selected parts should be purchase d only through Keithley to maintain accuracy and f unctionality 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, Keithle y 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 degr ee 1 or 2.

To clean an instrument, use a cloth dampened with deionized water or mild, water-based cleaner. Clean the ext erior 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 bec omes contaminated and operation is affected, the board should be returned to the factor y for proper cleaning/servicing.

4. Store the handle-mount assembly, screws, an d handle together for future use.

Instrument power

Follow the steps below to connect the 2470 to line po wer and turn on the instrument. The 2470 operates from a line voltage of 100 V to 240 V at a f requency of 50 Hz or 60 Hz. It automatically senses line voltage and frequency. Make sure the operating voltage in your area is compatible.

You must turn on the 2470 and allow it to warm up for at least one hour to achieve rated accuracies.

Operating the instrument on an incorrect line voltage may cause damage to the instrument, possibly voiding the warranty.

The power cord supplied with the 2470 contains a separate protective earth (safety ground) wire for use with grounded outlets. When proper connections are made, the instrument chassis is connected to power-line ground through the ground wire in the power cord. In addition, a redundant protective earth connection is provided through a scre w on the rear panel. This terminal should be connected to a known protective earth. In the event of a failure, not using a properly grounded protective earth and grounded outlet may result in personal injury or death due to electric shock.

Do not replace detachable mains supply cords with inadequately rated cords. Failure to use properly rated cords may result in personal injury or death due to electric shock.

Remote communications interfaces

You can choose from one of several communication i nterfaces to send commands to and receive responses from the 2470.

You can control the 2470 from only one communications interface at a time. The first interface on which the instrument receives a message takes control of the instrument. If another interface sends a message, that interface can take control of t he inst rument. You may need to enter a password to change the interface, depending on the setting of interface access.

Reference Manual

2: Installation Model 2470 High Voltage SourceMeter Ins trument

The 2470 automatically detects the type of communications interface (LAN, USB, or GPIB) when you connect to the respective port on the rear panel of t he inst rument. In most cases, you do not need to configure anything on the instrument. In addit ion, you do not need to reboot if you change the type of interface that is connected.

Supported remote interfaces

The 2470 supports the following remote interfaces:

• GPIB: IEEE-488 instrumentation general-purpose interface bu s

• USB: Type B USB port

• Ethernet: Local-area-network communications

• TSP-Link: A high-speed trigger synchronization and communications bus that test system

builders can use to connect multiple instruments in a master-and-subordinate configuration

For details about TSP-Link, see TSP-Link System Expansion Interface (on page 9-1

Comparison of the communications interfaces

The following topics discuss some of the advantages and disadvantages of the communications interfaces that are available for the 2470.

Simplicity

The GPIB interface is the simplest configurat ion. Connections are simple, and the only necessary software configuration is setting the instrum ent address.

An ethernet network is a simple configuration if you can use the automatic settings. It is more complicated if you need to set it up manually. If you must set up y our et hernet network manually, you need some knowledge of networking. In addition, your corporate information technology (IT) department may have restrictions that preve nt using an ethernet network.

A USB interface is also simple to set up. However, it requires an instrument-specific device driver to communicate with the instrument. This can limit the operating systems that are available for use with the instrument.

Triggering

The GPIB interface provides the fastest, most consistent triggering. It has the lowest trigger latency of the available communications types. Trigger latency is the time that it takes the trigger to go from the computer to the instrument. GPIB also allows you to send triggers to multiple instruments simultaneously.

2-8 2470-901-01 Rev. B / September 2019

Model 2470

Installation

High Voltage SourceMeter Instrument Reference Manual Section 2:

If you use a USB interface, it is difficult to synch ronize triggers that are sent to multiple instruments. For applications that require synchronized t ri ggering, you must use digital I/O. The trigger latency with a USB interface is higher than latency with a GPIB interface, but it is lower and more consistent than latency with an ethernet interface.

Transfer rate

Of the available interfaces, USB has the fastest tra nsfer rate, followed by the ethernet and GPIB interfaces. The GPIB interface, however, offers the most consistent transfer rate.

Instrument naming

Names for instruments that are named through NI-VISATM are in a human-readable format. USB instrument names are not intended to be human -readable.

Distance and instrument limitations

For GPIB and USB interfaces, the cabling distance s between the controller and instrument or hub are limited to 30 feet. In a system connected with GPIB or USB, you can have up to 15 instruments attached to each controller.

The distances for ethernet interfaces are unlimi ted if the ethernet address of the instrument and ports for the various services it uses are visible publi cly (for example, port 80 for web service). If you are using an ethernet interface, you can communicate wit h an instrument anywhere in the world. In a system that is connected through ethernet, the num ber of instruments you can attach to each controller is only limited by the controller and the connections available on that controller.

Expense

The GPIB interface is the most expensive method because of the costs for cabling and related equipment. Ethernet and USB connections are inex pensive options because most computers have built-in ethernet and USB ports. In addition, cables and hubs for ethernet and USB interfaces are inexpensive.

GPIB setup

This topic contains information about GPIB standards, bus connections, and primary address selection.

The 2470 GPIB interface is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common commands and status model topology.

You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum cable length is the lesser of either:

• The number of devices multiplied by 2 m (6.5 ft)

• 20 m (65.6 ft)

You may see erratic bus operation if you ignore these limits.

2: Installation Model 2470 High Voltage SourceMeter Ins trument

Install the GPIB driver software

Check the documentation for your GPIB controller for information about where to acquire drivers. Keithley Instruments also recommends that you check the website of the GPIB controller for the latest version of drivers or software.

It is important that you install the drivers before you connect the hardware. This prevents associating the incorrect driver to the hardware.

Install the GPIB cards in your compute r

Refer to the documentation from the GPIB controller vendor for information about installing the GPIB controllers.

Connect GPIB cables to your instrume nt

To connect a 2470 to the GPIB interface, use a cable equipped with standard GPIB connectors, as shown below.

Figure 10: GPIB connector

To allow many parallel connections to one instrument, stack the connectors. Each connector has two screws on it to ensure that connections remain secure. The figure below shows a typical connection diagram for a test system with multiple instrum ents.

To avoid possible mechanical damage, stac k no more than three connectors on any one instrument. To minimize interference caused by electromagnetic radiation, use only shielded GPIB cables. Contact Keithley Instrumen ts for shielded cables.

Installation

High Voltage SourceMeter Instrument Reference Manual Section 2:

Figure 11: IEEE-488 connection example

To connect the GPIB cable to the instrument:

1. Align the cable connector with the connector on the 2470 rear panel.

2. Attach the connector. Tighten the screws securely but do not overtighten them.

3. Connect any additional connectors from other in st ruments, as required for your application.

4. Make sure that the end of the cable is properly con nected to the controller.

Set the GPIB address

The default GPIB address is 18. You can set the address from 1 to 30 if it is unique in the system. This address cannot conflict with an addres s t hat is assigned to another instrument or to the GPIB controller.

GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an address of 21.

The instrument saves the address in nonvolatile memory. It does not change when you send a reset command or when you turn the power off and on agai n.

2470-901-01 Rev. B / September 2019 2-11

Section

Reference Manual

To set the GPIB address from the front panel:

1. Press the MENU key.

2. Select Communication.

3. Select the GPIB tab.

4. Set the GPIB Address.

5. Select OK.

You can also set the GPIB address using remote com m ands. Set the GPIB address with the SCPI command :SYSTem:GPIB:ADDRess or the TSP command gpib.address.

Effect of GPIB line events on 2470

The GPIB has control lines that allow predefined i nformation, called events, to be transferred quickly. The following information lists some of the GPIB l i ne events and how the 2470 reacts to them.

DCL

This event clears the GPIB interface. When the 2470 detects a device clear (DCL) event, it does the following:

• Clears the input buffer, output queue, and command queue

• Cancels deferred commands

• Clears any command that prevents the processing of any other device command

A DCL event does not affect instrument settings and stored data.

GET

The group execute trigger (GET) command is a GPIB trigger that triggers the instrument to take readings from a remote interface.

GTL

When the instrument detects the go to local (GTL ) event, it exits remote operation and enters local operation. When the instrument is operating locally, you can control the instrument from the front panel.

IFC

When the instrument detects an interface clear (IFC) event, the instrument enters the talker and the listener idle state. When the instrument is in this state, the GPIB  indicators on the front panel are not displayed.

2-12 2470-901-01 Rev. B / September 2019

Model 2470

Installation

High Voltage SourceMeter Instrument Reference Manual Section 2:

An IFC event does not interrupt the transfer of comm and messages to and from the instrument. However, messages are suspended. If the transfer of a response message from the instrument is suspended by an IFC event, the transfer resumes when the instrument is addressed to talk. If transfer of a command message to the instrument is su spended by an IFC event, the rest of the message can be sent when the instrument is addressed to listen.

LLO

When the instrument detects a local-lockout (LLO) event, all front-panel controls except the OUTPUT ON/OFF and POWER switches are disabled.

To enable the front panel, use the go-to-local (GTL) event.

REN

When the instrument detects the remote enable (RE N) event, it is set up for remote operation. The instrument is not placed in remote mode when it detects the REN event; the instrument must be addressed to listen after the REN event before it goes into remote mode.

You should place the instrument into remote mode before you attempt to program it using a remote interface.

SDC

The selective device clear (SDC) event is similar t o the device clear (DCL) event. However, the SDC event clears the interface for an individual inst rument instead of clearing the interface of all instruments.

When the 2470 detects an SDC event, it will do the following for the selected instrument:

• Clears the input buffer, output queue, and comm and queue

• Cancels deferred commands

• Clears any command that prevents the processing of any other device command

An SDC event does not affect instrument settings an d stored data.

SPE, SPD

When the instrument detects the serial polling enabl e (SPE) and serial polling disable (SPD) events, it sends the status byte of the instrument. This contains the serial poll byte of the instrument.

The serial poll byte contains information about internal functions. See the Status model (on page 16-1 for detail. Generally, the serial polling seque nce is used by the controller to determine which of several instruments has requested service with t he SRQ line.

LAN communications

You can communicate with the instrument using a lo cal area network (LAN). The LAN interface can be used to build flexible test systems that include web access. This section provides an overview of LAN communications for the 2470.

When you connect using a LAN, you can use a web browser to access the internal web page of the instrument and change some of the instrument set t i ngs.

The 2470 is a version 1.5 LXI Device Specificati on 2016 instrument that supports TCP/IP and complies with IEEE Std 802.3 (ethernet LAN). There is one LAN port (located on the rea r panel of the instrument) that supports full connectivity on a 10 Mbps or 100 Mbps network. The 2470 automatically detects the speed.

The 2470 also supports Multicast DNS (mDNS) and DNS Service Discovery (DNS-SD), which are useful on a LAN with no central administration.

Contact your network administrator to confirm your specific network requirements before settin g up a LAN connection.

If you have problems setting up the LAN, refer to LAN t roubles hooti ng sugge stio ns (on page 2-22

LAN cable connection

The 2470 includes a LAN crossover cable. You can use this cable for the TSP-Link® network or LAN communications.

However, you can use any standard LAN crossover cable (RJ-45, male-to-male) or straight-through cable to connect your equipment. The instrument automatically senses which cable you have connected.

The following figure shows the location of the LAN port on the rear panel of the instrument. Connect the LAN cable between this connection and the LAN port on the computer.

You can connect the instrument to the LAN in a one-to-one, one-to-many, two network card, or enterprise configuration, as described in the following topics.

Model 2470

Installation

High Voltage SourceMeter Instrument Reference Manual Section 2:

One-to-one connection

With most instruments, a one-to-one connection is done only when you are connecting a single instrument to a single network interface card.

A one-to-one connection using a network crossover cabl e c onnection is similar to a typical RS-232 system using a null modem cable. The crossover ca ble has its receive (RX) and transmit (TX) lines crossed to allow the receive line input to be connected to the transmit line output on the network interfaces.

Figure 13: One-to-one connection with a crossover cable

The 2470 supports Auto-MDIX and can use either normal LAN CAT-5 cables (patch) or crossover cables. The instrument automatically adjusts t o s upport either cable.

One-to-many connection

With a LAN hub, a single network interface card ca n be connected to as many instruments as the hub can support. This requires straight-through network (not cro ssover) cables for hub connections.

The advantage of this method is easy expansion of measurement channels when the test requirements exceed the capacity of a single inst rument. With only the instruments connected to the hub, this is an isolated instrumentation netwo rk. However, with a corporate network attached to the hub, the instruments become part of the larger network.

Two network card connection

If you need to connect independent corporate and i nstrumentation networks, two network interface cards are required in the computer controller. Though the two networks are independent, stations on the corporate network can access the instruments and the instruments can access the corporate network using the same computer.

This configuration resembles a GPIB setup in which the computer is connected to a corporate network, but also has a GPIB card in the computer to communicate with instruments.

High Voltage SourceMeter Instrument Reference Manual Section 2:

Instrumentation connection to enterprise routers or servers

This connection uses an existing network infrast ructure to connect instruments to the computer controller. In this case, you must get the networ k resources from the network administrator.

Usually, the instruments are kept inside the corporate firewall, but the network administrator can assign resources that allow them to be outside the firewall. This allows instruments to be connected to the internet using appropriate security methods. Data collection and distribution can be controlled from virtually any location.

High Voltage SourceMeter Instrument Reference Manual Section 2:

Raw socket connection

All Keithley instruments that have LAN connections support raw socket communication. This means that you can connect to the TCP/IP port on the instrument and send and receive commands. A programmer can easily communicate with the i nstrument using the Winsock API on computers with the Microsoft

Apple

computers.

VXI-11 connection

This remote interface is similar to GPIB and supports message boundaries, serial poll, and service requests (SRQs). A VXI-11 driver or NI-VISA NI-VISA and can be used with the VXI-11 interface. You can expect a slower connection with this protocol.

Telnet connection

The Telnet protocol is similar to raw socket and can b e used when you need to interact directly with the instrument. Telnet is often used for debugging and troubleshooting. You will need a separate Telnet program to use this protocol.

Windows® operating system or using the Berkeley S ockets API on Linux® or

software is required. Test Script Builder (TSB) uses

The 2470 supports the Telnet protocol, which you can use over a TCP/IP connection to send commands to the instrument. You can use a Telnet connection to interact with scripts or send real-time commands.

Dead socket connection

The dead socket termination (DST) port is used to terminate all existing ethernet connections. A dead socket is a socket that is held open by the instrument because it has not been properly closed. This most often happens when the host computer is turned off or restarted without first closing the socket. This port cannot be used for command and control functions.

Use the dead socket termination port to manually disconnect a dead session on any open socket. All existing ethernet connections will be termi nated and closed when the connection to the dead socket termination port is closed.

Reset LAN settings

You can reset the password and the LAN settings from the rear panel by inserting a straightened paper clip into the hole below LAN RESET.

Turn the 2470 output on or off

You can turn the 2470 output on from the front panel or by sending remote commands.

Turning the 2470 output off does not place the instrument in a safe state (an interlock is provided for this function).

Hazardous voltages may be present on all output and guard terminals. To prevent electrical shock that could cause injury or death, never make or break connections to the 2470 while the instrument is powered on. Turn off the equipment from the front panel or disconnect the main power cord from the rear of the 2470 before handling cables. Putting the equipment into an output-off state does not guarantee that the outputs are powered off if a hardware or software fault occurs.

When the source of the instrument is turned off , it may not completely isolate the instrument from the external circuit. You can use the Output Off setting to place the 2470 in a known, noninteractive state during idle periods, such as when you are changing the device under test. The output-off states that can be selected for a 2470 are normal, high-impe dance, zero, or guard.

See Output-off state (on page 4-16

) for additional details.
