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
Source/measure unit, SMU, can simultaneously perform DC voltage or current output
and measurement. Typical SMU 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 high current
measurement and low resistance measurement. 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.
Chassis ground (green terminal) should be connected to the ground shield which
covers the DUT including the guard shield to minimize the affect of noise. Or else, the
chassis ground should be opened.
The following image is the source and measurement terminals of Keysight B2900. For
the B2900, the High Force, High Sense, and Guard are the same potential. And the
Low Force and Low Sense are the same potential.

4.3” color TFT WQVGA (480272, with LED backlight) provides a graphical user
interface (GUI) with the following features.
•4-view modes (Single, Dual, Graph, Roll view)
•Easy-to-use key operations
•Easy access to basic and advanced source/measurement capabilities
Single view
Single view provides basic and advanced settings and display capabilities for the
selected channel from the front panel of the instrument. No additional controller or
software is required.
Dual view
Dual view provides the basic settings and display capabilities for both channels 1
and 2. Up to 6½ digits can be displayed in the Dual view mode. This mode is
available only for the B2902A and B2912A.
Graph view
Graph view displays measurement results on XY graphs (such as I-V and I-t/V-t
curves) on up to 2 channels. This is useful for quick evaluation of device
characteristics, especially those obtained from sweep measurements.
Roll view
Roll view draws I-t or V-t curves similar to the curves drawn by a strip chart
recorder. Up to 1000 acquired data points can be displayed and updated while the
measurement is still in progress. Roll view’s continuous measurement capability is
especially useful for monitoring low frequency phenomena. Roll view is available
only for the B2911A and B2912A.

Program Memory
Program memory allows you to s t ore lo ng s t ring s o f S CPI co mmand lines once into
the built-in volatile memory and then recall those strings multiple times while the
program is executing us ing a single SCPI command . By storing the command
strings in memory, the time that would have been spent sending those same
commands over a communication bus is eliminated. For tests that utilize lots of
repeated code (such as subroutines), program memory can dramatically reduce test
times.

Afin d'éviter de toucher l'extrémité du câble d'allongement ou l'aire de la
borne avec l'appareil mis sous tension (AST), couvrez les conducteurs avec
l'isolant. En outre, il est important de protéger la zone de la borne en utilisant
le couvercle d'écran à la mise à terre, ou tout autre élément.
Afin d’éviter toute décharge électrique et dommage MST, ne branchez ou
déconnectez pas la sortie MST alors que la source de sortie est appliquée.
Lorsque vous touchez le MST après la mesure, élaborez une contre-mesure de
la charge résiduelle et du chauffage afin d'éviter tout choc électrique et toute
brûlure. Utilisez des gants et des outils. Prévoyez également du temps pour la
décharge et la radiation.
2-Wire Connections or 4-Wire Connections
When connecting a DUT, you can choose the connection type either 2-wire
connections or 4-wire connections.
If you want to simplify the connections, use 2-wire connections by connecting the
Force terminals only and opening the Sense terminals. The Force terminals can be
used to apply and measure DC voltage or current.
To make 4-wire connections, remote sensing, well known as Kelvin connections,
use both Force and Sense terminals. Connecting the Force and Sense lines together
at the terminal of the DUT minimizes the measurement error caus ed by the residu al
resistance of the test leads or cables. This connection is effective for low resistance
measurements and high current measurements.
To specify the connection type (Sensing Type), perform the following procedure.
1. Press the Config > Source > Connection function keys. This opens the Output
Connection dialog box.
2. Set the Sensing Type on this dialog box. Choose 2-WIRE for 2-wire
connections, or 4-WIRE for 4-wire connections.

NOTEPerforming high voltage measurement
When the Digital I/O interlock terminal is open, B2900 cannot apply high voltage
over 42 V. To perform high voltage measurements, B2900 must be connected to
the interlock circuit installed in 16442B.
Prepare the N1294A-011 or 012 interlock cable, and connect it between the B2900
Digital I/O connector and the 16442B Intlk connector. B2900 can apply a high
voltage when the test fixture cover is closed.
WARNINGHazardous voltage, instrument maximum output voltage may appear at the
High Force, High Sense, and Guard terminals if the fixture cover is closed.
To prevent electrical shock, do not expose these lines.

Guarding
A
Buffer
Guard
High Force
DUT
Guarding reduces the leakage current between the instrument and a DUT. This is
important when you measure a low current.
Figure 3-10 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 3-7 and 3-8, the guard is extended to
the test fixture input connectors with triaxial cables.

Installing the Interlock Circuit
Installing the Interlock Circuit
The interlock circuit is a simple electric circuit, as shown in Figure 3- 11. The circuit
electrically opens when an access door is opened, and closes when the door is
closed.
B2900 cannot apply high voltages over 42 V when the Digital I/O interlock
terminal is open. To perform high voltage measurements, the B2900 interlock
terminal must be connected to the interlock circuit installed in the measurement
environment such as the shielding box. The interlock circuit is important and
necessary to prevent electrical shock when the user touches the measurement
terminals.
WARNINGHazardous voltage, instrument maximum output voltage may appear at the
High Force, High Sense, and Guard terminals if the fixture cover is closed.
To prevent electrical shock, do not expose these lines.

LAN Interface
NOTEFor detailed information about LAN interface connections, refer to Connectivity
Guide installed with the Keysight IO Libraries.
The following steps will help you quickly get started with connecting and
configuring your instrument on a local area network.
Connecting to a Site LAN
A site LAN is a local area network in which LAN-enabled instruments and
computers are connected to the network via routers, hubs, and/or s witches. They are
typically large, centrally-managed networks with services such as DHCP and DNS.
1. If you hav e not al read y d one s o, in st all the Ke ysi ght IO Libraries Suite from the
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 LAN indicator will turn green when the
LAN port has been configured successfully, or turn red if the configuration fails.

Communicating Over the LAN
Communicating Over the LAN
Using the Graphical Web Interface
Your Keysight B2900 Source/Measure Unit 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 B2900 without using I/O libraries or drivers.
NOTEThe built-in graphical web interface only operates over the LAN interface. It
requires Internet Explorer 6+ or Firefox 2+. You will als o 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.
Keysight B2900 User’s Guide, Edition 53-31
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 B2900 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 fr om the factor y, the password is set to Keysight, keysight, or agilent. T o change the pas sword, click on the View & Modify Con figuration bu tton.
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 B2900
without using I/O libraries or drivers. In all cases, you must first establish a LAN
connection from your computer to the B2900 as previously described.
In an MS-DOS Command Prompt box, type “telnet hostname 5024” where hostname is the B2900’s hostname or IP address, and 50 24 is the ins trument’s telnet
port. You should get a Telnet session box with a title indicating that you are
connected to the B2900. Type the SCPI commands at the prompt.
Using Sockets
NOTEKeysight B2900 allows any combination of up to four simultaneous data 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.
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?
3-32Keysight B2900 User’s Guide, Edition 5
Installation
Communicating Over the LAN
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, and all query responses returned on the control socket will be terminated
with a newline.
T o send a device clear , send the strin g “DCL” to the control s ocket. When the B2900
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.
