Keysight E36100B Series Operating and Service Guide20
Extending the Voltage Range and Current Range
The power supply may be able to provide voltages and currents greater than its rated maximum outputs if the
power- line voltage is at or above its nominal value.
Operation can be extended up to 3% over the rated output without damage to the power supply, but performance
cannot be guaranteed to meet specifications in this region. If the power- line voltage is maintained in the upper end
of the input voltage range, the power supply willprobably operate within its specifications. The power supply is more
likely to stay within specifications if only one of the voltage or current outputs is exceeded.
Series connections
You can connect up to four E36100B Series power supplies up to the output isolation rating of any one supply to
obtain a higher voltage than a single power supply can produce. Series-connected power supplies can be operated
with one load across both power supplies or with a separate load for each power supply. The power supply has a
reverse polarity diode connected across the output terminals so that if operated in series with other power supplies,
damage will not occur if the load is short-circuited or if one power supply is turned on separately from its series
partners.
When the series connection is used, the output voltage is the sum of the voltages of the individual power supplies.
The current is the current of any one power supply. Each of the individual power supplies must be adjusted in order
to obtain the total output voltage.
Parallel connections
You can connect up to four E36100B Series power supplies in parallelto obtain a total output current greater than
a single power supply can produce. The total output current is the sum of the output currents of the individual
power supplies. The output of each power supply can be set separately. The output voltage controls of one power
supply should be set to the desired output voltage; the other power supply should be set for a slightly higher output
voltage. The supply with the higher output voltage setting will deliver its constant current output, and drop its
output voltage until it equals the output of the other supply, and the other supply will remain in the constant voltage
operation and only deliver that fraction of its rated output current which is necessary to fulfill the total load demand.

Remote Control
You can control the instrument remotely in two ways. To program the instrument via SCPI, use Keysight IO
Libraries. To control the instrument via a simulated front panel, use the instrument's Web interface.
Keysight IOLibraries Suite
Keysight IOLibraries Suite is a collection free instrument control software that automatically discovers instruments
and allows you to control instruments over the LAN, USB, GPIB, RS-232, and other interfaces.
E36100B Series Web interface
You can monitor control the instrument from a Web browser by using the instrument's Web interface. To connect,
simply enter the instrument's IP address or hostname in your browser's address bar and hit Enter.
If you see an error indicating 400: Bad Request, that is related to an issue with "cookies" in your Web browser. To
avoid this issue, either start the Web interface by using the IPaddress (not host name) in the address bar), or clear
cookies from your browser immediately before starting the Web interface.
Check the checkbox below the picture of the instrument to enable an indicator on the instrument's front panel. This
is helpful if you have severalE36100B Series instruments and you wish to identify the one to which you are
connected.
The Configure LANtab on the top allows you to change the instrument's LAN parameters; exercise caution when
doing so, as you may interrupt your ability to communicate with the instrument.

Keysight E36100B Series Operating and Service Guide
When you click the Control Instrument tab, the instrument will ask you for a password (default is keysight, all lower
case), and then it will open a new page, shown below.
This interface allows you to use the instrument just as you would from the front panel. Note the curved arrow keys
that allow you to "turn" the knob. You can click the knob to "push" it, just as you would push any of the other keys
on the front panel.
Read warning
Be sure to read and understand the warning at the top of the Control Instrument page.
Keysight E36100B Series Operating and Service Guide28
Technical connection details
In most cases, you can easily connect to the instrument with the IO Libraries Suite or Web interface. In certain
circumstances, it may be helpful to know the following information.
The vendor ID: 0x2A8D, the product ID is 0x0902, and the instrument serial number is MY55160003.
The product ID varies by model: 0x0602 (E36102B), 0x0702 (E36103B), 0x0802 (E36104B), 0x0902 (E36105B), 0x0A02 (E36106B).
Using sockets
Power supplies allow data socket to be made.
Keysight instruments have 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 E36100B Series Operating and Service Guide32
Introduction to the SCPI Language
Standard Commands for Programmable Instruments (SCPI) is an ASCII- based instrument command language
designed for test and measurement instruments. Refer to Simplified Programming Overview for basic techniques for
programming the power supply over the remote interface.
SCPI commands are based on a hierarchical structure, also known as a tree system. In this system, associated
commands are grouped together under a common node or root, thus forming subsystems. A portion of the
SOURce subsystem is shown below to illustrate the tree system.
[SOURce:]
CURRent {<current>|MIN|MAX|UP|DOWN} CURRent? [MIN|MAX]
CURRent:
TRIGgered {<current>|MIN|MAX} TRIGgered? {MIN|MAX}
VOLTage {<voltage>|MIN|MAX|UP|DOWN} VOLTage? [MIN|MAX]
VOLTage:
SOURce is the root keyword of the command, CURRent and VOLTage are second-level keywords, and TRIGgered is
the third- level keyword. A colon (:) separates a command keyword from a lower- levelkeyword.
33
Keysight E36100B Series Operating and Service Guide
Command format used in this manual
The format used to show commands in this manual is shown below:
CURRent {<current>|MINimum|MAXimum|UP|DOWN}
The command syntax shows most commands (and some parameters) as a mixture of upper- case and lower- case
letters. The upper- case letters indicate the abbreviated spelling for the command. For shorter program lines, send
the abbreviated form. For better program readability, send the long form.
For example, in the above syntax statement, CURR and CURRENT are both acceptable forms. You can use uppercase or lower- case letters. Therefore, CURRENT, curr, and Curr are allacceptable. Other forms, such as CUR and
CURREN, will generate an error.
Braces ({}) enclose the parameter choices for a given command string. The braces are not sent with the command
string.
A vertical bar (|) separates multiple parameter choices for a given command string.
Triangle brackets (<>) indicate that you must specify a value for the enclosed parameter. For example, the above
syntax statement shows the current parameter enclosed in triangle brackets. The brackets are not sent with the
command string. You must specify a value for the parameter (such as CURR 0.1).
Some parameters are enclosed in square brackets ([]). The brackets indicate that the parameter is optional and can
be omitted. The brackets are not sent with the command string. If you do not specify a value for an optional
parameter, the power supply chooses a default value.
A colon (:) separates a command keyword from a lower-levelkeyword. You must insert a blank space to separate a
parameter from a command keyword. If a command requires more than one parameter, you must separate
adjacent parameters using a comma as shown below:
SOURce:CURRent:TRIGgered
APPLy 3.5,1.5
Keysight E36100B Series Operating and Service Guide34
Command separators
A colon (:) separates a command keyword from a lower- levelkeyword as shown below:
SOURce:CURRent:TRIGgered
A semicolon (;) is used to separate two commands within the same subsystem, and can also minimize typing. For
example, sending the following command string,
SOUR:VOLT MIN;CURR MAX
is the same as sending the following two commands:
SOUR:VOLT MIN
SOUR:CURR MAX
Use a colon and a semicolon to link commands from different subsystems. For example, in the following command
string, an error is generated if you do not use the colon and semicolon:
DISP:TEXT:CLE;:SOUR:CURR MIN
Using the MIN and MAX parameters
You can substitute MINimum or MAXimum in place of a parameter for many commands. For example, consider the
following command:
CURRent {<current>|MIN|MAX}
Instead of selecting a specific current, you can substitute MINimum to set the current to its minimum value or
MAXimum to set the current to its maximum value.
Querying parameter settings
You can query the value of most parameters by adding a question mark (?) to the command. For example, the
following command sets the output current to 5 A:
CURR 5
You can query the value by executing:
CURR?
You can also query the maximum or minimum value allowed with the present function as follows:
CURR? MAX CURR? MIN
If you send two query commands without reading the response from the first, and then attempt to read the second
response, you may receive some data from the first response followed by the complete second response. To avoid
this, do not send a query command without reading the response. When you cannot avoid this situation, send a
device clear before sending the second query command.
35
Keysight E36100B Series Operating and Service Guide
SCPI command terminators
A command string sent to the power supply must terminate with a <new line> character. The IEEE- 488 EOI (endor-identify) message is interpreted as a <new line> character and can be used to terminate a command string in
place of a <new line> character. A <carriage return> followed by a <new line> is also accepted. Command string
termination will always reset the current SCPI command path to the root level. The <new line> character has the
ASCII decimal code of 10.
IEEE-488.2 common commands
The IEEE- 488.2 standard defines a set of common commands that perform functions like reset, self- test, and
status operations. Common commands always begin with an asterisk (*), are four to five characters in length, and
may include one or more parameters. The command keyword is separated from the first parameter by a blank space.
Use a semicolon (;) to separate multiple commands as shown below:
*RST; *CLS; *ESE 32; *OPC?
SCPI parameter types
The SCPI language defines several different data formats to be used in program messages and response messages.
Numeric parameters
Commands that require numeric parameters will accept all commonly used decimal representations of numbers
including optional signs, decimal points, and scientific notation. Special values for numeric parameters like
MINimum, MAXimum, and DEFault are also accepted.
You can also send engineering unit suffixes (V, A, or SEC) with numeric parameters. If only specific numeric values
are accepted, the power supply will automaticallyround the input numeric parameters. The following command
uses a numeric parameter:
CURR {<current>|MIN|MAX|UP|DOWN}
Discrete parameters
Discrete parameters are used to program settings that have a limited number of values such as BUS and IMM. Query
responses will always return the short form in all upper- case letters. The following command uses discrete
parameters:
TRIG:SOUR {BUS|IMM}
Boolean parameters
Boolean parameters represent a single binary condition that is either true or false. For a false condition, the power
supply will accept OFF or 0. For a true condition, the power supply will accept ON or 1. When you query a boolean
setting, the power supply will always return 0 or 1. The following command uses a boolean parameter:
DISP {OFF|ON}
Keysight E36100B Series Operating and Service Guide36
String parameters
String parameters can contain virtually any set of ASCII characters. A string must begin and end with matching
quotes; either with a single quote or with a double quote. You can include the quote delimiter as part of the string
by typing it twice without any characters in between. The following command uses a string parameter:
DISP:TEXT <quoted string>

Keysight E36100B Series Operating and Service Guide
Error Messages
The instrument returns error messages in accordance with the SCPI standard.
—
Up to 20 errors can be stored in the instrument's error queue, and the triangle annunciator above ERR turns on
when one or more errors are in the error queue.
— Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. When you have read all errors
from the error queue, the ERR annunciator turns off.
— If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is replaced with -
350,"Queue overflow". No additional errors are stored until you remove errors from the queue. If no errors have
occurred when you read the error queue, the instrument responds with +0,"No error".
— Send SYSTem:ERRor? to read the most recent error. Each error is in the format: -104,"Data type error".
—
To read the error queue from the front panel, press [Menu], then turn the knob to Error and press the knob to
select it. Then rotate the knob to view the error codes. Be sure to record the error messages, because they will be
cleared when you exit the error list.
— The error queue is cleared by power cycles and *CLS., but not *RST.

SCPI Status Registers
All SCPI instruments implement status registers in the same way. The status system records various instrument
conditions in three register groups: the Status Byte register, the Standard Event register, and the Questionable
Status register groups. The Status Byte register records high-level summary information reported in the other
register groups.
What is an event register?
An event register is a read-only register that reports defined conditions within the instrument. Bits in an event
register are latched. Once an event bit is set, subsequent state changes are ignored. Bits in an event register are
automaticallycleared by a query of that register (such as *ESR? or STAT:QUES:EVEN?) or by sending the *CLS (clear
status) command. A reset (*RST) or device clear will not clear bits in event registers. Querying an event register
returns a decimal value corresponding to the binary-weighted sum of all bits set in the register.
What is an enable register?
An enable register defines which bits in the corresponding event register are logically ORed together to form a single
summary bit. Enable registers are both readable and writable. Querying an enable register will not clear it. The *CLS
(clear status) command does not clear enable registers but it does clear the bits in the event registers. To enable bits
in an enable register, you must write a decimal value which corresponds to the binary- weighted sum of the bits you
wish to enable in the register.

CALibration Subsystem
For a detailed discussion on the calibration procedures, see Calibration Adjustment Procedures.
CALibration:COUNt?
Returns the number of times the instrument has saved calibration data as a signed whole number, for example +21.
Your instrument was calibrated at the factory; read and record the initial count when you receive the instrument.
CALibration:CURRent[:DATA][:HIGH] <value>
Enters an output current value (in amps) that you obtained by reading a DMM. You must first select a calibration
level (CAL:CURR:LEV) for the value being entered. This command can only be used when calibration is unsecured
and output is ON.
CALibration:CURRent[:DATA]:LOW <value>
Enters an output current value (in amps) that you obtained by reading a DMM. This is similar to
CALibration:CURRent[:DATA][:HIGH], but it is only used for small current calibration. This command can only be
used when calibration is unsecured and output is ON.
CALibration:CURRent:LEVel[:HIGH] MINimum|MAXimum
Initiates calibration for a specific current level. The MINimumcalibration must be performed before the MAXimum,
and you must unsecure this instrument to use this command.
CALibration:CURRent:LEVel:LOW MINimum|MAXimum
Initiates small current calibration for a specific current level. The MINimumcalibration must be performed before the
MAXimum, and you must unsecure this instrument to use this command.
Unsecures or secures the power supply with the calibration security code Of up to nine digits. The query returns 1
(ON - unsecured for calibration) or 0 (OFF - secured against calibration).
– The query only returns the state; it does not return the passcode.
– The security code is nonvolatile, and does is not changed by power cycling or *RST.
– The front panel limits the user to entering codes of up to six digits.
– The default passcodes are 36102, 36103, 36104, 36105, and 36106.
– Example: Unlock the instrument to enable calibration: CAL:STATe 1,36102
Keysight E36100B Series Operating and Service Guide46
CALibration:STRing "<string>"
CALibration:STRing?
Record or read up to 40 characters of instrument calibration information.
– You can store any information related to calibration, such as date or contact information.
– The power supply must be unsecured before sending a calibration message.
– You can read the string regardless of whether the supply is secured.
CALibration:VOLTage[:DATA] <value>
Enters an output voltage value (in volts) that you obtained by reading a DMM.
– You must first select a calibration level (CAL:CURR:LEV) for the value being entered.
– This command can only be used when calibration is unsecured and output is ON.
CALibration:VOLTage:LEVel MINimum|MAXimum
Initiates calibration for a specific voltage level. You must do the MINimum calibration before the MAXimum, and this
command can only be used when calibration is unsecured.

CURRent Subsystem
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude] <current> | MINimum | MAXimum |UP | DOWN
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]? [MINimum | MAXimum]
Programs the immediate current level of the instrument's output. See Programming Ranges for details.
This command changes the output immediately. The UP and DOWN parameters increase or decrease the
immediate current by the amount specified by CURRent:STEP. A setting that exceeds the maximum or minimum
rated current will cause error -222 (Data out of range).
Sets the time (in milliseconds) that the overcurrent protection is temporarily disabled after a current levelchange.
The query returns a number of the form +#.########E+##.
Enables or disables overcurrent protection, which causes the instrument to go into a protected state when the
power supply status is in constant current mode. The query returns 1 (ON)or 0 (OFF).
[SOURce:]CURRent:PROTection:TRIPped?
Indicates whether an overcurrent protection occurred (1) or not (0). This is reset to 0 by
CURRent:PROTection:CLEar.
Keysight E36100B Series Operating and Service Guide48
Displays a message of up to 12 characters on the front panel. Additional characters are truncated.
DISPlay[:WINDow][:STATe] ON | 1 | OFF | 0
DISPlay[:WINDow][:STATe]?
Turns the display off or on. When the displayis turned off, outputs are not sent to the display and all annunciators
except ERROR are disabled. The display state is automatically turned on when you return to the local mode. Press
and hold [Lock/Unlock] for a few seconds to return to the local mode.

(0through9) are nonvolatile.
– The parameters stored in a state file are the same parameters affected by *RST.
– States are not affected by the *RSTcommand.
– Saving a state overwrites the previous state (if any) stored in that location.
– When shipped from the factory, storage locations 0through9 are empty.
51
Keysight E36100B Series Operating and Service Guide
*SRE <enable value>
*SRE?
Enables bits in the Status Byte enable register. The query returns the decimal value corresponding to the binaryweighted sum of all bits set in the register.
*STB?
Queries the Status Byte summary register. This is similar to a serialpoll but it is processed like any other instrument
command. The *STB? command returns the same result as a serial poll but the “Request Service” bit (bit 6) is not
cleared if a serial poll has occurred.
*TRG
Generates an event trigger to the trigger system when the trigger system has a BUS (software) trigger as its trigger
source (TRIG:SOUR BUS). If the trigger system is not initiated, the *TRG command is simply ignored.
*TST?
Performs a complete self-test of the power supply and returns “0” (pass) or a non-zero value (fail). If the self-test
fails, an error message is also generated with additional information on why the test failed.
The bits added together to produce a non-zero value in the case of a failing self-test are shown below.

OUTPut Subsystem
OUTPut[:STATe] ON |1 | OFF |0
OUTPut[:STATe]?
Enables or disables the instrument's output.The query returns 0 (OFF) or 1 (ON). At *RST, the output state is off.
OUTPut:PROTection:CLEar
Clears the latch that disables the output due to an overvoltage or overcurrent condition. You must clear the
conditions that cause the fault before executing this command. You can then restore the output to the state that
existed before the fault condition occurred.
Specifies whether the instrument's power-on state is the *RST state (default) or the state stored in one of ten
memory locations.
Keysight E36100B Series Operating and Service Guide54
STATus Subsystem
STATus:OPERation:[EVENT]?
Returns a decimal value corresponding to the binary-weighted sum of the bits in the event register of the Operation
Status group. This read-only register stores (latches) all events that are passed by the Operation NTR and/or PTR
filter.
– Reading the Operation Status Event register clears it.
– *RST has no effect on this register.

SYSTem Subsystem
SYSTem:COMMunicate:RLSTate LOCal |REMote | RWLock
SYSTem:COMMunicate:RLSTate?
Places the instrument in remote or local mode. The LOCal parameter is the same as SYSTem:LOCal, the REMote
parameter is the same as SYSTem:REMote, and the RWLock parameter is the same as SYSTemRWLock. The query
returns LOC, REM, or RWL.
SYSTem:ERRor[:NEXT]?
Queries the power supply's error queue. When the front-panel ERR annunciator turns on, one or more errors have
been detected. Up to 20 errors can be stored in the error queue. See Error Messages.
— Errors are retrieved in first-in-first-out (FIFO) order. The ERR annunciator turns off after the last error is read.
— If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is replaced with -
350, “Queue overflow”. No additional errors are stored until you remove errors from the queue. If no errors have
occurred when you read the error queue, the power supply responds with +0, “No error”.
— The error queue is cleared when power has been off or after a *CLS (clear status) command has been executed.
The *RST (reset) command does not clear the error queue.
SYSTem:LOCal
Places the power supply in the local mode. All keys on the front panel are fullyfunctional.
SYSTem:REMote
Places the power supply into remote mode for remote operation. When the unit is being controlled remotely, the
power supply will go to remote mode automatically. You can switch the instrument to local mode using
SYSTem:LOCal or by pressing any key on the front panel.
57
Keysight E36100B Series Operating and Service Guide
SYSTem:RWLock
Places the power supply in the remote mode. This command is the same as SYSTem:REMote, except that all frontpanel keys, excluding the [Lock/Unlock] key are disabled. You can unlock the front panel by holding the
[Lock/Unlock] key. This switches the instrument to local mode at the same time. The front panel willbe unlocked
when the instrument is switched to remote or local mode.
SYSTem:SECurity:IMMediate
Clears and sanitizes all user memory (states, LAN information, and so on), usuallyto prepare the instrument for
removal from a secure area. Instrument identification data (instrument firmware, model number, serial number,
MAC address and calibration data) is not erased. This procedure is not recommended for routine use because of the
possibility of unintended data loss.
SYSTem:VERSion?
Returns the SCPI version on which the instrument's command set is based, which is 2005.0.
Keysight E36100B Series Operating and Service Guide58
Triggering Commands
ABORt
Clears any pending delayed trigger and returns the trigger system to idle. If INIT:CONT is enabled, the trigger system
is continuously initiated.
INITiate[:IMMediate]
Cause the trigger system to initiate. When the trigger system is initiated, an event on the specified trigger source
causes the corresponding trigger action on the power supply output. This command completes one full trigger
cycle when the trigger source is IMMediate or initiates the trigger subsystem when the trigger source is BUS.
INITiate:CONTinuous ON | 1 | OFF | 0
INITiate:CONTinuous?
Enables or disables continuous initiation of the trigger system. If this is disabled, an INIT initiates the trigger system
for only one trigger action. If this is enabled, the trigger system is continuously initiated and INIT is redundant. The
query returns 1 (ON) or 0 (OFF).
*TRG
Generates an event trigger to the trigger system when the trigger system has a BUS (software) trigger as its trigger
source (TRIG:SOUR BUS). If the trigger system is not initiated, the *TRG command is simply ignored.
TRIGger[:SEQuence]:DELay <seconds> MINimum | MAXimum
TRIGger[:SEQuence]:DELay? [MINimum | MAXimum]
Sets the time delay (in seconds, from 0 to 32.767)from the detection of a bus trigger to the start of any
corresponding trigger action on the power supply output. The default is 0, and the query returns a number of the
form +#.########E+##.
TRIGger[:SEQuence]:SOURce BUS | IMMediate
TRIGger[:SEQuence]:SOURce?
Specifies the source from which the instrument will accept a trigger, either a bus (software) trigger or an internal
immediate trigger. At *RST, the bus trigger source is selected. To ensure synchronization when the bus source is
selected, send the *WAI (wait) command. You can also use the *OPC? (operation complete) query or the *OPC
command to indicate when the operation has completed. The query returns BUS (wait for trigger command) or
IMM (continuous triggering).
59
Keysight E36100B Series Operating and Service Guide
Enables or disables overvoltage protection, which causes the instrument to go into a protected state when the
power supply goes above the protection level specified by the VOLTage:PROTection[:LEVel]. The query returns 1
(ON)or 0 (OFF).
[SOURce:]VOLTage:PROTection:TRIPped?
Indicates whether an overvoltage protection occurred (1) or not (0). This is reset to 0 by
VOLTage:PROTection:CLEar.
Specifies whether the instrument uses remote or local sensing. The query returns 0 (INT)or 1 (EXT).
The internal setting sets a relaywithin the power supply to connect the output and sensing connector. This means
that only two wires are used; and remote sensing is disabled. The external setting sets a relay within the power
supply to disconnect the output and remote sensing inputs. This means that four wires are used; and remote
sensing is enabled. The Internal setting displays 2W in the upper left corner of the display, and the External setting
shows 4W in the upper left corner.

Keysight E36100B Series Operating and Service Guide63
Electrostatic Discharge (ESD) precautions
Almost all electrical components can be damaged by electrostatic discharge (ESD) during handling. Component
damage can occur at electrostatic discharge voltages as low as 50 V.
The following guidelines will help prevent ESD damage during service operations:
– Disassemble instruments only in a static-free work area.
– Use a conductive work area to reduce static charges.
– Use a conductive wrist strap to reduce static charge accumulation.
– Minimize handling.
– Keep replacement parts in original static-free packaging.
– Remove all plastic, foam, vinyl, paper, and other static-generating materials from the immediate work area.
Troubleshooting
Before troubleshooting or repairing the instrument, make sure the failure is in the instrument rather than any
external connections. Also make sure that the instrument was accurately calibrated within the last year (see
Calibration Adjustment Procedures > Calibration Interval for details).
Perform the following verifications if the unit is inoperative:
– Verify that the ac power cord is connected to the power supply.
– Verify that the front-panel power switch is depressed.
– Verify that the power-line fuse is installed:
– Use the 2.0 AT, 250 V fuse for 100 or 115 Vac operation.
– Use the 1.0 AT, 250 V fuse for 230 Vac operation.
– Verify the power-line voltage setting.
– See Getting Started > Options and Fuse Information for details.
64
Keysight E36100B Series Operating and Service Guide
Self-test procedures
A power-on self-test occurs automaticallywhen you turn on the power supply. This limited test assures you that the
power supply is operational.
The complete self-test of the power supply is enabled by pressing the Recall key or any front panel keys except the
Error key and the power-line switch simultaneously . Then continue to press the Recall key for 5 seconds. It will take
another 2 seconds for the complete self-test to end.
You can also perform a complete self-test from the remote interface see SCPI Programming for details.
– If the self-test is successful, "PASS" is displayed on the front panel.
– If the self-test fails, "FAIL" is displayed and the ERROR annunciator turns on. Record the error code and message
and contact Keysight support if necessary.
– If the self-test is successful, this indicates a high chance that the power supply is operational.
To replace the power-line fuse
The power-line fuse is located within the power supply's fuse-holder assemblyon the rear panel see Getting Started
> Options and Fuse Information for details. For 100 or 115 Vac operation, you must use a 2.0 AT time-delay fuse.
For 230 Vac operation, you must use a 1.0 AT time-delay fuse.

Test considerations
– Ensure that the calibration ambient temperature is stable and between 20 °C and 30 °C.
– Ensure ambient relative humidity is less than 80%.
– Allow a 1-hour warm-up period before verification or calibration.
– Keep cables as short as possible, consistent with the impedance requirements.
66
Keysight E36100B Series Operating and Service Guide
The tests should be performed by qualified personnel. During performance verification tests, hazardous voltages
may be present at the outputs of the power supply.
Measurement techniques
Voltmeter
To ensure that the values read by the voltmeter during both the verification procedure and the calibration procedure
are not affected by the instantaneous measurement of the AC peaks of the output current ripple, make several DC
measurements and average them.
Current-monitoring resistor
The 4-terminal current shunt is used to eliminate output current measurement error caused by voltage drops in the
load leads and connections. It has special current-monitoring terminals inside the load connection terminals.
Connect the voltmeter directly to these current-monitoring terminals.
Electronic load
Many of the test procedures require the use of a variable load capable of dissipating the required power. If a variable
resistor is used, switches should be used to connect, disconnect, or short the load resistor. For most tests, an
electronic load can be used. The electronic load is considerably easier to use than load resistors, but it may not be
fast enough to test transient recovery time and may be too noisy for the noise (PARD) tests.
Fixed load resistors may be used in place of a variable load, with minor changes to the test procedures. Also, if
computer controlled test setups are used, the relativelyslow (compared to computers and system voltmeters)
settling times and slew rates of the power system may have to be taken into account. "Wait" statements can be used
in the test program if the test system is faster than the power system.
Setup for most tests
Keysight E36100B Series Operating and Service Guide67
This setup is used for most tests and it requires the DMM, electronic load, and power supply being verified. Some
wire is also required for connection between instruments. A LAN or USB cable is needed for readback data. The
DMM measures the power supply output, and the electronic load draws current from the power supply. The
accuracy of the current monitoring resistor must be 0.01% or better, which should include any self-heating effects.
Constant Voltage (CV) verification
Voltage programming and readback accuracy
These tests verify that the voltage programming and the LAN or USB readback functions are within specifications.
Note that the readback values over the remote interface should be identical to those displayed on the front panel,
but with maximum resolution.

Output noise verification
Periodic and random output deviations superimpose a residual AC voltage on the DC output. This residual voltage is
specified as the rms or peak-to-peak noise in and is specified in the product data sheet.
1.
Turn off the power supply using the AC line switch.
2.
Connect a load resistor or electronic load, differential amplifier, and an oscilloscope (AC coupled) to the output
as shown below.
3.
Use an appropriate load resistor (see load resistor value Recommended test equipment list) to keep the power
system at the instrument setting specified in the test record form under “CV Ripple and Noise”. See the Test
Record Forms under “CV Ripple and Noise” for details.
4.
As shown in the figure, use two BNC cables to connect the differential amplifier to the (+) and (−) output terminals. Each cable should be terminated by a 50 Ω resistor. The shields of the two BNC cables should be connected together. Connect the differential amplifier output to the oscilloscope with a 50 Ω termination at the
oscilloscope input.
5.
Set the differential amplifier to multiply by ten, divide by one, and 1 MΩ input resistance. Set the differential amplifier's positive and negative inputs to AC coupling. Set the oscilloscope’s time base to 5 ms/div, and the vertical
scale to 10 mV/div. Turn the bandwidth limit on (usually 20 or 30 MHz), and set the sampling mode to peak
detect.

Calibration Adjustment Procedures
This chapter includes calibration adjustment procedures for Keysight E36100B Series power supplies. Instructions
are applicable for performing the procedures from either the front panel or a controller over the LAN or USB.
Perform the verification tests before calibrating your instrument. If the instrument passes the verification tests, the
unit is operating within its calibration limits and does not need to be re-calibrated.
Closed–case electronic calibration
The instrument uses closed-case electronic calibration; no internal mechanical adjustments are required. The
instrument calculates correction factors based on reference signals that you apply and stores the correction factors
in non-volatile memory. This data is not changed by cycling power, *RST, or SYSTem:PRESet.
Calibration interval
The recommended calibration interval for Keysight E36100B Series power supplies is one year.
Calibration adjustment process
The following general procedure is recommended to complete a full calibration adjustment.
1.
Adhere to the test considerations. See Performance Verification > Test considerations for details.
2.
Perform the performance verification tests to characterize the instrument. See Performance Verification for
details.
3.
Unsecure the instrument for calibration. See Calibration security for details.
4.
Perform the calibration procedures. See Calibration procedure for details.
5.
Secure the instrument against the calibration. See Calibration security for details.
6.
Take note of the security code and calibration count in the instrument's maintenance records.
7.
Perform the performance verification tests to verify the calibration.
88
Keysight E36100B Series Operating and Service Guide
Calibration security
The instrument has a calibration security code to prevent accidental or unauthorized calibration. When you receive
your power supply, it is secured by a default security code, as shown below. The security code is not changed by a
power cycle or *RST.
ModelDefault code
E36102B036102
E36103B036103
E36104B036104
E36105B036105
E36106B036106
You can enter a security code of up to 6 digits on the front panel or up to 9 digits from the remote interface.
To reset a forgotten security code to its factory default, you can turn on the instrument after shorting
CAL SECURE jumper J3 inside the instrument as shown below.
Keysight E36100B Series Operating and Service Guide89
Calibration count
The instrument counts the number of times it has saved calibration data. Your instrument was calibrated at the
factory; when you receive your instrument, read and record the initial count. You can only read the calibration count
by sending the CAL:COUNt? query, and the calibration count is not change by a power cycle or *RST.
If Auto Save is enabled, the count increments when you exit the calibration state. To avoid double counting, do not
manually save the count with Auto Save enabled.
Calibration message
You can use the CALibration:STRing command to store a message of up to 40 characters in calibration memory. For
example, you could store the last calibration date, the calibration due date, or contact information for the person
responsible for calibration. The calibration message is not affected by a power cycle or *RST.
You can only store the calibration message when the instrument is unsecured, but you can execute the
CALibration:STRing? query regardless of whether the instrument is secured. A new calibration message overwrites
the previous message, and messages over 40 characters are truncated.
Saving calibration data
You must always save new calibration data before cycling instrument power or leaving the calibration state with the
Auto Save feature off. To save calibration data, send CAL:SAVE or save the calibration data from the front panel.
Calibration auto save
The instrument includes a calibration Auto Save feature. This feature automatically saves the calibration data to
non-volatile memory and increments the calibration count when you exit the calibration state.
To enable or disable the CAL auto Save feature, send CAL:ASAV ON or CAL:ASAV OFF. To query the CAL auto Save
state, send CAL:ASAV?
Calibration procedure
Enter the calibration state
To begin the calibration procedure, you must enter the calibration state.
