Power Supply and Measurement Safety

• Power Supply Safety

This instrument can output high currents and voltages. Make sure that the load or device under test can safely handle the output current and voltage. Also, make sure that the connection leads can safely withstand the expected currents and are insulated for the expected voltages.

The instrument outputs may be connected so as to float relative to earth ground. Isolation or floating voltage ratings are indicated on the instrument, near the output terminal or the Chassis ground terminal. There is the danger of electric shock by touching the floated measurement terminals. Keep in mind it to protect yourself. And it is a reason of using the recommended accessories.

• Voltage/Current Measurement Safety

Multimeters and other instruments capable of measuring high voltages and currents are subject to specific safety concerns because of the circuits to which they may be connected. To safely use these instruments, you need to understand the markings on the instrument near the input terminals, which include the Protection Limits and the IEC Measurement Category.

• Protection Limits

Keysight multimeters and other voltage measurement instruments provide protection circuitry to prevent damage to the instrument and to protect against the danger of electric shock, provided the Protection Limits are not exceeded. To ensure safe operation of the instrument, do not exceed the Protection Limits shown on the input terminals.

• Source/Measure Terminals

High Sense, for 4-wire connection

High Force

Guard

Chassis ground

Low Force

Low Sense, for 4-wire connection

This instrument can simultaneously perform DC voltage or current output and measurement, and has the Force, Sense, and Guard terminals as shown below. Normally the Force, Sense, and Guard are the same potential. Voltage marked around the terminals indicates the Protection Limits.

Force and Sense must be connected to a terminal of a device under test (DUT) for the 4-wire connection (Kelvin connection) which is effective for applying voltage accurately. For the 2-wire connection to ease the connections, connect Force only. Do not connect Sense. It must be opened.

Guard should be connected to the guard shield which covers the DUT high side wiring for reducing leakage current caused by the wire. Or else, the Guard must be opened.

• Current

• Voltage

• Resistance

•Power

• Percent-to-Limit (= measured value / Limit value  100 %)

Resistance data is given by Resistance = Vmeas / Imeas. Power data is given by Power = Vmeas  Imeas. In the above formula, Vmeas is the voltage measurement data, and Imeas is the

current measurement data. For using the resistance compensation, see “Resistance Compensation” on page

6-18.

NOTE Measurement Range

Voltage source uses the present output range to measure voltage and/or the minimum range which covers the Limit value to measure current.

Current source uses the present output range to measure current and/or the minimum range which covers the Limit value to measure voltage.

Limit

B2961A/B2962A has a compliance feature that limits the output voltage or current to prevent damage to the device under test. When the channel applies voltage, you can specify the current limit. When the channel applies current, you can specify the voltage limit. For details, see “Limit/Compliance” on page 6-3.

Guarding

Guarding reduces the leakage current between the instrument and a DUT. This is important when you measure a low current.

Figure 3-11 shows the theory of guarding. The buffer amplifier (1) keeps the

potential of the Guard conductor at the same potential as the High Force conductor, so that the current does not flow between the High Force and Guard conductors. Therefore, the current measured by the instrument is the same as the current at the DUT terminal because no current is leaked.

For the connection examples shown in Figu res 3-8 and 3-9, the guard is extended to the test fixture input connectors with triaxial cables.

CAUTION Never connect the Guard terminal to any output, including circuit common, chassis

ground, or any other guard terminal. Doing so will damage the B2961A/B2962A.

1. If you hav e not alread y done so, install the Keysight I O Li brarie s S uit e fro m t he CD shipped with your product.

2. Connect the instrument to the site LAN. The factory-shipped instrument LAN settings are configured to automatically obtain an IP address from the network using DHCP (DHCP is enabled). Note that this may take up to one minute. The DHCP server will register the instrument’s hostname with the dynamic DNS server. The hos tname as well as the IP address can then be used to commu nicate with the instrument. The front panel display’s LAN indicator will turn green when the LAN port has been configured successfully, or turn red if the configuration fails.

Installation

Connecting to the Interfaces

NOTE If you need to manually configure any instrument LAN settings, see “LAN

Configuration dialog bo x” on page 4-45 for informat ion about conf igur ing the LAN

settings from the front panel of the instrument.

3. Use the Connection Expert utility from Keysight IO Libraries Suite to add the B2961A/B2962A and verify the connection. To add the instrument, you can request Connection Expert to discover the instrument. If the instrument canno t be found, add the instrument using the instrument’s hostname or IP address.

NOTE If this does not work, refer to the troubleshooting section in Connectivity Guide.

4. You can now use the Interactive IO within Connection Expert to communicate with your instrument, or program your instrument using various programming environments. You can also use the W eb browser o n your compu ter to connect to the instrument as described under “Using the Graphical Web Interface”.

Viewing the Active LAN Status

T o view the currently active LAN settings, press the More function key, then the I/O > LAN > Status softkeys. The LAN status dialog box appears.

Note that the currently active LAN settings for the IP Address, Subnet Mask, and Default Gateway may be different from the settings specified in the LAN Configuration dialog box, depending on the configuration of the network. If the settings are different, it is because the network has automatically assigned its own settings.

Modifying the LAN Settings

As shipped from the factory, B2961A/B2962A’s pre-configured settings should work in most LAN environments. If you need to manually configure these settings, press the More function key, then the I/O > LAN > Config softkeys. The LAN Configuration dialog box appears.

NOTE B2961A/B2962A must be rebooted if the host name is changed.

For the LAN setup parameters, see “LAN Configuration dialog box” on page 4-45.

Communicating Over the LAN

Using the Graphical Web Interface

Your Keysight B 296 1A/B2962A has a built-in graphical web interface that lets you control it directly from an Web browser on your computer. Multiple simultaneous connections are allowed, but only from one computer. With additional connections, performance will be reduced. Multiple connections from multiple computers are not allowed.

With the graphical web interface, you can access the front panel control functions including the LAN configuration parameters. This is a convenient way to communicate with the B2961A/B2962A without using I/O libraries or drivers.

NOTE The built-in graphical web interface only operates over the LAN interface. It

requires Internet Explorer 6+ or Firefox 2+. You will also need the Java Plug-in. This is included in the Java Runtime Environment. Visit the Java’s website.

The graphical web interface is enabled when shipped.

Installation

Communicating Over the LAN

To launch the graphical web interface:

1. Open a Web browser on your computer.

2. Enter the instrument’s hostname or IP address into the browser’s Address field to launch the graphical web interface. The B2961A/B2962A home page will appear.

3. Click on the Browser Web Control button in the navigation bar on the left to begin controlling your instrument.

4. For additional help about any page, click “Help with this Page”.

If desired, you can control the access to the graphical web interface using password protection. As shipped from th e factory, the password is set to keysight or agilent. To change the password, click on the View & Modify Configuration button. Refer to the online help for additional information about setting the password.

Using Telnet

The Telnet utility (as well as sockets), is another way to communicate with B2961A/B2962A without using I/O libraries or drivers. In all cases, you must first establish a LAN connection from your computer to the B2961A/B2962A as previously described.

In an MS-DOS Command Prompt box, type “telnet hostname 5024” where hostname is the B2961A/B2962A’s hostname or IP address, and 5024 is the instrument’s telnet port. You should get a Telnet session box with a title indicating that you are connected to the B2961A/B2962A. Type the SCPI commands at the prompt.

Using Sockets

NOTE Keysight B2961A/B2 962 A allow s any combination of up to four simult aneou s dat a

socket, control socket, or telnet connections to be made.

Keysight instruments are standardized on using port 5025 for SCPI socket services. A data socket on this port can be used to send and receive ASCII/SCPI commands, queries, and query responses. All commands must be terminated with a newline for the message to be parsed. All query responses will also be terminated with a newline.

Keysight B2961A/B2962A User’s Guide, Edition 3 3- 35

Installation Communicating Over the LAN

The socket programming interface also allows control socket connections. The control socket can be used by a client to send device clear and to receive service requests. Unlike the data socket, which uses a fixed port number, the port number for a control socket varies and must be obtained by sending the following SCPI query to the data socket: SYSTem:COMMunicate:TCPip:CONTrol?

Once the port number is obtained, a control socket connection can be opened. As with the data socket, all commands to the control socket must be terminated with a newline, a nd all query responses returned on the control socket will be terminated with a newline.

To send a device clear, send the string “DCL” to the control socket. When the B2961A/B2962A has finished performing the device clear, it will echo the string “DCL” back to the control socket.

Service requests are enabled for control sockets using the Service Request Enable register. Once service requests have been enabled, the client program listens on the control connection. When SRQ becomes true, the instrument will send the string “SRQ +nn” to the client. The “nn” is the status byte value, which the client can use to determine the source of the service request.
