The upper left corner of the display shows either CV or CC to indicate that the instrument is in constant voltage or constant current mode. Below that is either 2W or 4W, to indicate whether 2-wire (normal) or 4-wire (remote sensing) measurement is in use. The right side of the display shows the output voltage and current (when the output is enabled), and the voltage and current settings are shown near the bottom of the screen.

The very bottom of the screen can show arrows, each of which represents a different annunciator.

Label Meaning

ERR An error has occurred.

OCP An overcurrent protection event has occurred.

OVP An overvoltage protection event has occurred.

RMT The instrument is being programmed remotely.

LCK The front panel is locked.

To Set up the Instrument

Place the instrument's feet on a flat, smooth horizontal surface. Connect output and sense leads to the front panel, being careful not to short the leads together. Attach the power cable to the rear panel, then plug it into main power. Connect LAN or USB cables as desired, and you may also secure the instrument with a security lock cable.

Before disconnecting cables and cords from the instrument, turn the instrument off using the frontpanel power switch and disconnect from the supply source by unplugging the detachable power cord.

Options and Fuse Information

Be certain to order the proper instrument option for the mains power that will be used for the instrument.

Options 0EM, 0E3, and 0E9 determine which power-line voltage is selected at the factory. The default is configured for 230 VAC ± 10%, 47-63 Hz input voltage (option 0E3).

Option Description

0EM 115 VAC ± 10%, 47-63Hz input voltage

0E3 230 VAC ± 10%, 47-63Hz input voltage

0E9 100 VAC ± 10%, 47-63Hz input voltage

Ensure the correct AC input voltage and fuse settings

Use the proper switch settings

To change the input AC voltage selector on the power supply, use the two AC selector switches on the underside of the power supply as shown.

For example, to select 230 V, move the switch on the left to the left and the switch on the right to the right, as illustrated in the diagram below the switches. To select 115 V, move both switches to the position on the right, and to select 100 V, move the two switches toward each other.

Use the correct fuse

You must use a time delay 2-A fuse for 100- and 115-VAC inputs, and a time delay 1-A fuse for 230-VAC inputs:

Part Number Description Manufacturer Application

2110-1639 Fuse 1A 250V Time-delay Littelfuse 230-V line voltage

2110-1640 Fuse 2A 250V Time-delay 100- and 115-V line voltage

To configure the correct fuse, follow the three steps shown below:

Pull the fuse holder out of the power supply.

Insert the proper fuse into the fuse holder.

Re-insert the fuse holder into the power supply.

Programming Ranges

The following table shows the maximum voltage, current, and power that can be programmed for each model. The DEFault voltage is always 0 V.

Model Max Voltage (V) Max Current (A) Max Power(W)

E36102A 6 5.0 30

E36103A 20 2.0 40

E36104A 35 1.0 35

E36105A 60 0.6 36

E36106A 100 0.4 40

Note that the actual programmable values are 3% above these nominal values, but instrument specifications are only guaranteed up to the values shown in this table.

E36106A .001 V .01 V .001 A .0001 A .001 mA

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 will probably 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 E36100 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 E36100 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.

Front-panel Operation

This section describes how to perform the following operations from the instrument's front panel.

Configure the LAN interface

Set voltage and current

Specify 2- or 4-wire measurement

to turn the output off.

Constant voltage and constant current

If the output load resistance exceeds the voltage setting divided by the current setting, the instrument will operate in constant voltage mode. The current willequal the voltage divided by the load resistance.

If the output load resistance is less than the voltage setting divided by the current setting, the instrument will operate in constant current mode. The voltage will equal the current multiplied by the load resistance.

Specify 2- or 4-wire measurement

You have the option to use the remote sense terminals on the front panel to measure the voltage at the device under test (DUT). To specify whether you want to use this option:

1. Press [Menu].

2. Turn the knob to Sense Setting and press the knob.

3. Turn the knob to Internal or External and press the knob.

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.

Configure Overcurrent Protection (OCP) and Overvoltage Protection (OVP)

1. Press [Menu].

2. Turn the knob to OCP Set or OVP Set and press the knob.

Press the knob again to choose OCP Delay or OVP Level.

Turn the knob to the desired OCP or OVPlimit value. Then press the knob.

5. Turn the knob to OCP On, OCP Off, OVPOn, or OVP Off and press the knob to enable or disable

OCP or OVP.

6. Turn the knob to Exit Menu and press the knob.

If OCP or OVP is enabled, the instrument will display a triangle above the OCP or OVP annunciator.

Clear an OCP or OVP event

The instrument prominently displays an OCPTRIPPED or OVPTRIPPEDmessage to indicate an overcurrent or overvoltage event. The triangle above OCP or OVP flashes continuouslyuntil the event is cleared.

The output will be automatically turned OFF when OCP/OVP occurs.

To begin, correct the condition that caused the OCP or OVP event. There are three ways to do this:

Turn off OCP or OVP as described above.

Set the current or voltage level to be less than the OCP or OVP level. You may be able to do this by adjusting the voltage setting, the current setting, or the resistance of the load.

Set the OCP or OVP limit value to be above the current or voltage level.

2. Press [Menu].

3. Turn the knob to OCP Set or OVP Set and press the knob.

Turn the knob to the desired OCP or OVP limit value (if it needs to be changed). Then press the knob.

5. Turn the knob to OCP Clear or OVP Clear and press the knob.

Clear an overtemperature protection (OTP) event

The instrument prominently displays an OTPTRIPPED message to indicate an OTP event. In addition, the triangle above ERR will flash continuously until the error event is cleared.

The output will be automatically turned OFF when OTP occurs.

The overtemperature event willbe logged in the Error list, and you must clear the OTP event before the output can be turned ON again.

To begin, correct the condition that caused the OTP event and allow the instrument to cool.

2. Press [Menu].

3. Turn the knob to Error and press the knob. The instrument will briefly display a message like 3

ERRORS (the number will vary) to indicate how many errors are in the queue.

Turn the knob to cycle through the error codes, recording them as you go. Press the knob to view the error description. Press [Menu] to exit and clear the error list.

An OTP event will occur again after it is cleared if the instrument remains overheated.

Lock and unlock the front panel

If you are in a menu, you must exit the menu before locking the front panel.

1. Press [Lock / Unlock] to lock the front panel. This produces an LCK annunciator triangle, as shown

below.

If you press a key after the front panel is locked, the display willread HOLDKEY. That message indicates that you must press and hold the [Lock / Unlock] key to unlock the front panel and clear the LCK triangle.

Save or recall the instrument's state

The instrument allows you to save and recallthe instrument state in one of 10 memory locations, labeled 0through9. This allows you to quickly configure the instrument for commonly used applications.

An instrument state includes the instrument's output enable status, voltage and current settings, and OCP and OCV settings. It does not include error codes or LAN configuration information.

To save or recall the instrument state

1. Press [Menu].

2. Turn the knob to Store (or Recall) and press the knob.

3. Turn the knob to an option from Store 0 to Store 9 (or Recall 0 to Recall 9)and press the knob to

store or recall the present state of the instrument in the specified memory location.

The instrument will briefly display DONE.

Configure the Power-on State

The instrument allows you to recall the power-on state as either the default (*RST) state or the state stored in one of 10 memory locations (0through9). To configure the power-on state:

1. Press [Menu].

2. Turn the knob to Power-on and press the knob.

Turn the knob to Default, or a state from Recall0 to Recall9 and press the knob to make your selection.

The instrument will briefly display CHANGED SAVED if the recall state is different from the previous state, and NOCHANGE if the same state was selected.

Read error codes

You only need to do this if there is a triangle over shown below. Be sure to follow the procedure below carefully, and record each error code in order. Once you exit this menu, there is no way to retrieve the error codes again.

in the lower left corner of the screen, as

ERR

1. Press [Menu].

2. Turn the knob to Error and press the knob. The instrument will briefly display a message like 3

ERRORS (the number will vary) to indicate how many errors are in the queue.

Turn the knob to cycle through the error codes, recording them as you go.

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 IOLibraries Suite

Keysight IOLibraries 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. For more information, or to download IO Libraries, go to www.keysight.com/find/iosuite.

E36100 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 IPaddress (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 severalE36100 Series instruments and you wish to identify the one to which you are connected.

The Configure LANtab 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.

When you click the Control Instrument tab, the instrument willask 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.

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.

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:

TRIGgered {<voltage>|MIN|MAX} TRIGgered? {MIN|MAX}

SOURce is the root keyword of the command, CURRent and VOLTage are second-level keywords, and TRIGgered is the third- levelkeyword. A colon (:) separates a command keyword from a lower- level keyword.

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 upper- case or lower- case letters. Therefore, CURRENT, curr, and Curr are all acceptable. Other forms, such as CUR and CURREN, willgenerate 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-level keyword. 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

Command separators

A colon (:) separates a command keyword from a lower- level keyword 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.

SCPI command terminators

A command string sent to the power supply must terminate with a <new line> character. The IEEE- 488 EOI (end-or-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, selftest, 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 automatically round 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 willalways return the short form in allupper- 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}

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>

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 automatically cleared 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 willnot 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.

APPLy Subsystem

Specifies and changes the output voltage and current in one command.

– The DEFault, MINimum, and MAXimum values for each mode are shown in Programming Ranges.

– The query returns a quoted string with the voltage setting before the current setting.

– Both values returned by the query have five decimal points: "25.00000,0.75000"

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 MINimumcalibration 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 MINimumcalibration must be performed before the MAXimum, and you must unsecure this instrument to use this command.

CALibration:STATe <state>,<code> CALibration:STATe?

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

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

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).

[SOURce:]CURRent[:LEVel][:IMMediate]:STEP[:INCRement] <current> | DEFault [SOURce:]CURRent[:LEVel][:IMMediate]:STEP[:INCRement]? [DEFault]

Sets the step size for current programming with the CURRent UP and CURRent DOWN commands. The query returns a number of the form +#.########E+##.

[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude] <current> | MINimum | MAXimum [SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude]? [MINimum | MAXimum]

Sets the triggered current level in amps. The query returns a number of the form +#.########E+##.

[SOURce:]CURRent:PROTection:CLEar

Clears an overcurrent protection event.

[SOURce:]CURRent:PROTection:DELay[:TIME] <time> | MINimum |MAXimum [SOURce:]CURRent:PROTection:DELay[:TIME]? [MINimum |MAXimum]

Sets the time (in milliseconds) that the overcurrent protection is temporarily disabled after a current level change. The query returns a number of the form +#.########E+##.

[SOURce:]CURRent:PROTection:STATe ON|1|OFF|0 [SOURce:]CURRent:PROTection:STATe?

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.

DISPlay Subsystem

DISPlay[:WINDow]:TEXT:CLEar

Clears the message displayed on the front panel.

DISPlay[:WINDow]:TEXT[:DATA] "<string>" DISPlay[:WINDow]:TEXT[:DATA]

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 display is 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.

IEEE-488 Subsystem

*CLS

Clears all event registers, the Status Byte register, and the error queue.

ESE <enable value> ESE?

Enables bits in the Standard Event Enable register. The selected bits are then reported to the Status Byte. The query returns a decimal value corresponding to the binary-weighted sum of all bits in the register. All of the enabled events of the Standard Event Status Event Register are logically ORed to cause the Event Summary Bit (ESB) of the Status Byte Register to be set.

6 64 0 (reserved for future use)

7 128 PON Power-on has occurred

*ESR?

Returns a decimal value corresponding to the binary-weighted sum of all bits in the Standard Event register and clears the register to 0. The bit configuration is the same as the Standard Event Status Enable register (see *ESE).

*IDN?

Returns the power supply’s identification string in the form shown below.

Keysight Technologies,E36102A,MY87654321,0.3.2-0.32

The four comma-separated fields are the manufacturer name, instrument model number, instrument serial number, and revision code.

OPC OPC?

Sets the “Operation Complete” bit (bit 0) of the Standard Event register after the command is executed. The query returns 1 to the output buffer after the command is executed.

*OPT?

Returns the option number of the instrument.

PSC 0|1 PSC?

(Power- on status clear) Enables (1)or disables (0) the clearing of the Status Byte and the Standard Event register enable masks when power is turned on.

*RST

Resets the instrument to its default state, but does not clear any of the status registers or the error queue. It also does not affect any interface error conditions.

Parameter Default Value

OCP delay 50 ms

OVP level Maximum (varies by model)

Voltage 0

Current Maximum (varies by model)

OCP state Off

OVP state Off

Output state Off

Relay sense Internal

RCL <state> SAV <state>

Saves (*SAV) the current instrument state or recalls (*RCL) a previously saved state file. All state storage locations (0through9) are nonvolatile.

– The parameters stored in a state file are the same parameters affected by *RST.

– States are not affected by the *RSTcommand.

– Saving a state overwrites the previous state (if any) stored in that location.

– When shipped from the factory, storage locations 0through9 are empty.

SRE <enable value> SRE?

Enables bits in the Status Byte enable register. The query returns the decimal value corresponding to the binary-weighted sum of allbits set in the register.

*STB?

Queries the Status Byte summary register. This is similar to a serial poll 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.

5 32 ADC failure

6 64 DAC failure

7 128 (unused) (reserved for future use)

*WAI

Waits for all pending operations to complete before executing any additional remote interface commands. This command is used only in the triggered mode to wait for a pending delayed trigger.

MEASure Subsystem

MEASure:CURRent[:DC]?

Returns the sensed DCoutput current in amps in the format 1.23456789E+00.

MEASure[:VOLTage][:DC]?

Returns the sensed DCoutput voltage in volts in the format 1.23456789E+00. Use the [SOURce:]VOLTage:SENSe[:SOURce] command to specify whether the voltage uses internal or external (remote) sensing.

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.

OUTPut:PON:STATe RST|RCL0|RCL1|RCL2|RCL3|RCL4|RCL5|RCL6|RCL7|RCL8|RCL9| OUTPut:PON:STATe?

Specifies whether the instrument's power-on state is the *RST state (default) or the state stored in one of ten memory locations.

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.

STATus:OPERation:CONDition?

Returns a decimal value corresponding to the binary-weighted sum of the bits in the condition register of the Operation Status group. This read-only register holds the live (unlatched) operational status of the instrument.

– Reading the Operation Status Condition register does not clear it.

– *RST clears this register, other than those bits where the condition still exists after *RST.

STATus:OPERation:ENABle <value>

Sets the value of the enable register for the Operation Status group. The enable register is a mask for enabling specific bits from the Operation Event register to set the OPER (operation summary) bit of the Status Byte register.

– STATus:PRESet clears all bits in the enable register.

– *CLS does not clear the enable register, but does clear the event register .

STATus:PRESet

Sets the all registers to their power-on values.

STATus:QUEStionable:CONDition?

Returns a decimal value corresponding to the binary-weighted sum of the bits in the Questionable Status condition register.

– This register is a read-only register, which holds the instrument's live (unlatched) operational status.

– Reading the Questionable Status Condition register does not clear it.

– *RST clears this register, other than those bits where the condition still exists after *RST

STATus:QUEStionable:ENABle <enable value> STATus:QUEStionable:ENABle?

Enables bits in the Questionable Status enable register, which is a mask for enabling specific bits from the Operation Event register to set the QUES (questionable summary) bit of the Status Byte register. The selected bits are then reported to the Status Byte.

– STATus:PRESet clears all bits in the enable register.

– *CLS does not clear the enable register, but does clear the event register .

STATus:QUEStionable[:EVENt]?

Returns a decimal value corresponding to the binary-weighted sum of all bits in the Questionable Status event register.

– These bits are latched.

– Reading the event register clears it, but *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 fully functional.

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.

SYSTem:RWLock

Places the power supply in the remote mode. This command is the same as SYSTem:REMote, except that all front-panel 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.

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

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.

VOLTage Subsystem

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <voltage>|MINimum|MAXimum|DEFault [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]? [MINimum | MAXimum]

Sets the output voltage in volts.The query returns a number of the form +#.########E+##.

Sets the triggered voltage level in amps. The query returns a number of the form +#.########E+##.

[SOURce:]VOLTage:PROTection:CLEar

Clears an overvoltage protection event.

[SOURce:]VOLTage:PROTection:STATe ON|1|OFF|0 [SOURce:]VOLTage:PROTection:STATe?

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.

[SOURce:]VOLTage:PROTection[:LEVel] <voltage>|MINimum | MAXimum [SOURce:]VOLTage:PROTection[:LEVel]? [MINimum|MAXimum]

Sets the level at which overvoltage protection trips, in volts. The query returns a number of the form +#.########E+##.

[SOURce:]VOLTage:SENSe[:SOURce] INTernal | EXTernal

Specifies whether the instrument uses remote or local sensing. The query returns 0 (INT)or 1 (EXT).

If your instrument fails during the warranty period, Keysight Technologies will repair or replace it under the terms of your warranty. After your warranty expires, Keysight offers repair services at competitive prices. You also have the option to purchase a service contract that extends the coverage after the standard warranty expires.

Obtaining Repair Service (Worldwide)

To obtain service for your instrument, contact your nearest Keysight Technologies Service Center. They will arrange to have your unit repaired or replaced, and can provide warranty or repair–cost information where applicable. Ask the Keysight Technologies Service Center for shipping instructions, including what components to ship. Keysight recommends that you retain the original shipping carton for return shipments.

Repackaging for Shipment

Ensure the following to ship the unit to Keysight for service or repair:

– Attach a tag to the unit identifying the owner and indicating the required service or repair. Include the model number and full serial number.

– Place the unit in its original container with appropriate packaging material.

– Secure the container with strong tape or metal bands.

– If the original shipping container is unavailable, use a container that will ensure at least 10 cm (4 in.) of compressible packaging material around the entire instrument. Use static-free packaging materials.

Keysight suggests that you always insure your shipments.

Cleaning and Handling

Cleaning

To prevent electrical shock, disconnect the instrument from AC mains power and disconnect all test leads before cleaning. Clean the outside of the instrument using a soft, lint-free, cloth slightly dampened with water.

– Do not use detergent or solvents.

– Do not attempt to clean internally.

If required, contact a Keysight Technologies Sales and Service office to arrange for proper cleaning to ensure that safety features and performance are maintained.

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.

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 assembly on the rear panel see

Getting Started > Options and Fuse Information for details. For 100 or 115 Vac operation, you must use

a 2.5 AT slow-blow fuse. For 230 Vac operation, you must use a 2 AT slow-blow fuse.

User Replaceable Parts

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.

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 severalDC 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 relatively slow (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

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.

Turn off the power supply using the AC line switch.

Connect a DMM between the (+) and (–) terminals of the output.

If you are using a computer to control the power supply, connect a LAN or USB cable from the power supply to the PC.

Turn on the power supply using the AC line switch.

Transient response verification

This test measures the time for the output voltage to recover to within the specified value following a 50% change in the load current.

Turn off the power supply using the AC line switch.

Connect an oscilloscope and electronic load between the (+) and (–) terminals of the output to be tested as shown below.

If it turns to CC or UNREG, adjust the maximum current load so that the output current drops slightly until the CV annunciator lights up.

Adjust the oscilloscope to displaytransients as shown below. Note that the pulse width (t2-t1) of the transient at the voltage settling band, for example 15 mV for the E36102 from the base line is no more than 50 ms.

The oscilloscope cursors X1 and X2 represent t1 and t2.

Transient response specification is met when the voltage recovers within 50 μs.

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.

Turn off the power supply using the AC line switch.

Connect a load resistor or electronic load, differential amplifier, and an oscilloscope (AC coupled) to the output as shown below.

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.

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.

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.

Program the power supply to the settings indicated in the in the test record form for the appropriate model under “CV Ripple and Noise” see the Test Record Forms under Test Description of “CV Ripple and Noise” for details and enable the output. Let the oscilloscope run for a few seconds to generate enough measurement points. On the Keysight Infiniium oscilloscope, the maximum peak-to-peak voltage measurement is indicated at the bottom of the screen on the right side. Divide this value by 10 to get the CV peak-to-peak noise measurement. The result should not exceed the peak-to-peak upper limits for instrument's “CV Ripple and Noise, peak-to-peak.” See the Test Record Forms under “CV Ripple and Noise” for details.

Disconnect the oscilloscope and connect an rms voltmeter in its place. Do not disconnect the 50 Ω termination. Divide the reading of the rms voltmeter by 10. The result should not exceed the rms limits in the test record form for the appropriate model under “CV Ripple and Noise, rms”. See the Test

Record Forms under “CV Ripple and Noise” for details.

Calibration Adjustment Procedures

This chapter includes calibration adjustment procedures for Keysight E36100 series power supply. 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 E36100 series power supply is one year.

Calibration adjustment process

The following general procedure is recommended to complete a full calibration adjustment.

Adhere to the test considerations. See Performance Verification > Test considerations for details.

Perform the performance verification tests to characterize the instrument. See Performance Veri-

fication for details.

Unsecure the instrument for calibration. See Calibration security for details.

Perform the calibration procedures. See Calibration procedure for details.

Secure the instrument against the calibration. See Calibration security for details.

Take note of the security code and calibration count in the instrument's maintenance records.

Perform the performance verification tests to verify the calibration.

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.

Model Default Code

E36102A 36102

E36103A 36103

E36104A 36104

E36105A 36105

E36106A 36106

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.

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

Save the calibration data

To save calibration data, go to the ‘CAL Save’ menu to save the calibration data or enable the ‘Auto Save’ feature. With Auto Save, calibration data willbe saved when the user exits the calibration menu.

After completing the Voltage, Current and Small Current calibrations, save the calibration data before exiting the calibration state, or simply exit the calibration state if Auto Save is on.

To save the CAL data: CAL:SAVE

To enable the CAL Auto Save: CAL:ASAVE ON

To exit CAL State: CAL:STAT OFF, 36102
