2.4.3 Voltage & Current Limit Settings

The CV Limit refers to a required setting condition when outputting a constant voltage in need.
The CC Limit refers to a required setting condition when outputting a constant current in need.

The concept of the CV/CC limit setting is not the same as the Vrange’s at the section 3.10.5
since the limit depends on the relationships between the interactive factors of voltage setting,
resistance (RLoad), and rated/non-rated current. For example:

1. When
output constantly. The output current is in an inversed ratio with the RLoad.

2. When
output constantly. The output voltage is in a direct ratio with the RLoad, and it will stop

rising when the output voltage is equal to the setting value of the CV Limit, however, if the
RLoad increases, the power supply will turn to the CV mode to output.

Besides this, there is something you should know below.

If adjusting a CV limit under the Output ON, please make su re whether this supply is in the CV
mode since the knob rotation in the CV meter mode wil l trig the CV limit setting mode
simultaneously, and the values on the both displays are the same. In this case, if the sam e
condition exists in the CC mode, once the RLoad changes, it might burn out your DUT. So in
the CC mode, before the RLoad changes, you have to press the limit button once, and adjust
the CV limit value to protect your DUT.

If adjusting a CC limit under the Output ON, please make sure whether this supply is in the
CC mode since the knob rotation in the CC meter mode wil l t r ig the CC limit setting mode
simultaneously, and the values on the both displays are the same. In this case, if the same
condition exists in the CV mode, once the RLoad changes, it might burn out your DUT. So in
the CV mode, before the RLoad changes, you have to press the limit button once, and adjust
the CC limit value to protect your DUT.

To set the voltage and current limit values through the front panel, please follow the
procedures below.

3.4 Setting the Overvoltage Protectio n

The overvoltage protection is designed to prevent the load from output voltages that reach a
specified value greater than the defined protection value. To accomplish the OVP, the output
is shorted via an internal SCR w hen the trip level i s set greater than 3V or by programming the
output to 1V when the trip level is set to less than 3V.

The following procedures show how to set the OVP trip level, how to check OVP operation,
and how to clear overvoltage condition.

3.6 Remote Sensing (for 62010L-36-7 only)

Remote Sensing is applied to keep regulation from degrading which might occur due to the
voltage drop between the output connection of the power supply and the load.

After connecting the power supply to the load, voltage is sensed at the load r ather than at the
power supply’s output terminals. This connection allows the power supply to generate
sufficient voltage to the load automatically due to the voltage drop in applications with long
lead lengths, and read back an accurate voltage directly over the load.

When the Remote Voltage Sense is applied, the OVP circuit senses the voltage at the load
terminals, not the power supply output terminals.

How to use Remote Voltage Sense

There are three steps to using the Remote Voltage Sense. First of all, the output + and – of
the P9610A have to be wired to your DUT’s + and - terminals. Second, the sense + and – of
the P9610A have to be wired to your DUT’s + and - terminals. Third, you need to enable the
sense option via the front panel.

1. Wire the 62010L-36-7’s output to your DUT:
You can connect the output + & – of the power supply, and DUT’s + & - through either
banana leads, or bare leads.

2. Wire t he 62010L-36-7’s sense to your DUT:

The terminals of the positive sense (S+) and the negative sense (S-) are located with the
terminals of the positive transfer (T+), the negative transfer (T-), the positive recipient (R+),
and the negative recipient (R-). The terminals (T+/T-/R+/R-) are used for Master-Slave
control.

To wire the sense terminal of your power supply, you need t o use a screwdriver with a flat
head whose diameter is equivalent to or less than 3 millimeters. With the screwdriver
pressing on the red area, you can insert a lead into the terminal as shown below.

Negative Sense Connection Positive Sense connection

3. Enable the sense via the front panel operation:
To enable the remote sense, you have to turn off the output first and press the Menu
button once. The SENSE symbol will blink. Press the Menu button once again. The
display will show a blinking INT. Rotate the knob to display the blinking EXT symbol.
Press the Menu button to finish the setting. The output will return to the meter mode. The
sense signal will light at the right side of the display as shown below. To exit the
configuration session, press any other key to exit.

3.6.1 Constant Voltage Regulation

The constant voltage (CV) regulation specification for load applications applies at the output
terminals of the power supply. Under the Remote Voltage Sense, you have to add 5mV to this
specification for each drop of 1V between the positive load point and + output terminal of the
power supply since the load current is changed. For this potential issue, the lead length has to

Power Supply Operation

Note

Don’t use the shield as one of the sense conductors.

be taken into account. It is important to keep the resistance of the sense leads at or below

0.5Ohm for each lead in order to meet the above-specified performance.

3.6.2 Output Rating

The rated output voltage and current specifications apply at the output terminals. When using
Remote Voltage Sense, any voltage dropped along the load leads has to be taken into
account and added to the load voltage in order to achieve the correct output voltage. However,
the performance specifications cannot be assured when the maximum output voltage at the
output terminals is exceeded. In the event this occurs, UNREG will be shown on the display.

3.6.3 Output Interference

Any interference (noise) occurring on the sense leads also appears at the output of the power
supply. This may affect the voltage load regulation as well. To minimize external noise, it is
better to twist the sense leads, and run them in pa rallel and close to the load leads. The sense
leads must be shielded in any case, and the shield must be grounded at the pow er supply end
only.

3.6.4 Stability

When you use the external sense under certain combinations of load lead lengths, and large
load capacitances, a filter may be created as part of the voltage feedback loop. In addition,
the extra phase shift generated by this filter can decrease the power supply’s stability, slowing
down the transient response. In extreme cases, it may cause power supply oscillations. To
minimize this potential issue, keep the load leads as short as possible and twist them together.
When the remote sense leads are used, various adverse effects can occur as a result of
accidental open-connections of the sense or load leads during external sense operation. To
avoid these effects, please provide secure permanent connections.

3.6.5 Remote Sensing Connections

Remote Sensing needs to connect the load leads from the output terminals to the load and
the sense leads from the sense terminals to the load as shown below.

2. Before the connecting the external sense connections, we strongly

Wire Shielding & Load Line Impedance

When wiring any loads with the 62010L-36-7, some rules have to be kept in mind.

1. If the wiring to a load is long, the phase shift caused by the inductance and capacitance of
the wiring becomes non-negligible, and then causing oscillation. In that case, the
capacitor prevents oscillation.

2. If the load current changes to pulse form in a sud den, the ou tput volta ge may i ncrease due
to the effects from the inductance component o f the wiring. In that case, the capacitor also
prevents variations via output.

3. Twisting the load wires is able to reduce the inductance component, and stabilize the
output.

4. Use a capacitor whose withstand voltage is greater than or equal to 120% of the units
rated voltage.

5. When you finish using the remote sensing function, please remove the sensing wires, and
make su re to turn off the remote sensing by setting the sense state to INT (internal).

3.7 Master & Slave Application (62010L-36-7 Only)

If you have applications that need voltages and currents greater than the rated maximum
outputs, you can achieve this using multiple power supplies. The power supply can output an
extended range of voltages or currents by connecting more units. Up to 7 units, limited to the
same model, in series or in parallel may be connected if your application requires higher
output voltage or current, such as greater than 36V (up to 252V) or greater than 7A (up to
49A).

3.7.1 Connections in Series

To output voltage in the 36V to 252V range, connect two or more power supplies in series.
Series connections can be utilized up to the output isolation rating of any power supply in
order to obtain a higher voltage than that available from a single power supply. These 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 polarit y diode
connected across the output terminals. That means if operated in series with other power
supplies, damage will not occur if the load is short-circuited or if one of the power supplies is
turned on separately from its series partner.

The connection diagram for series connections is illustrated below.

How to accomplish series connections:

For example, in order to connect 3 units (62010L-36-7) in series to output 108V, follow the
procedures below. There a re three steps.

3.7.2 Connections in Parallel

To output current within the 7A to 49A range, parallel operation of two or more power supplies
is necessary. Using parallel connections, CV/CC capability, and the automatic crossover
operation, you can obtain a total output current greater than that available from single power
supply. The total output current is the sum of the currents from the connected power supplies.
The output of each power supply can be set separat ely. The output voltage controls of the

If you are a new user of the SCPI language, please read this chapter very car ef ully before
attempting to program the power supply. Incorrectly commanding the power supply could
cause unpredictable operation of the power supply output that may damage connected
devices.

4.1 SCPI Language Summary

4.1.1 SCPI Language Introduction

SCPI is an ASCII-based instrument command language designed for test and measurement
instruments. Its commands are based on a hierarchical structure, also known as a tree
system. In this system, related commands are grouped together under a common node or
root, or formed as subsystems. There is a tree example about a port ion of the SOURce
subsystem down here

[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}

4.1.2 Symbols Used in SCPI Commands

Before continue introduce the SCPI commands for 62000L series, you need to know the
following notations used for the SCPI command syntax.

 Square Brackets ([]) : Indicate optional keywords or parameters, and can be omitted.

The brackets are not sent with the command string. Braces ({}) : Enclose parameters
within a command string. The braces are not sent with the command string.

 Triangle Brackets (<>) : Indicate that you have to substitute a value or a code for the

enclosed parameter. For example, the SCPI command CURRent {<current>} whose
parameter is the current enclosed in triangle brackets means you have to specify a val ue
for the parameter such as 0.1A. The brackets are not sent with the command s tring.

 A Vertical Bar (|) : separates one of two or more alternative parameters.
 Colon (:) : Separates a command keyword from a lower-level keyword. For example,

SOURce:CURRent:TRIGgered.

 Blank Space ( ) : A blank space is used to separate a parameter from a command

keyword.

 Comma (,) : A comma (,) is used to separate parameters. For example, APPLy 36,3.

 Semicol on (;) : A semicolon (;) is used to separate two command string and let you can

combine two commands in a command string. For example, commanding with the

following string VOLT MAX;CURR MAX is the same as commanding with VOLT MAX
and then CURR MAX.

different subsystems. For example, in the following command string, an
error appears if they are not used.

4.1.3 Command Format in This Manual

The format use d on SCPI commands in this manual is like below.

CURRent {<current>|MINimum|MAXimum|UP|DOWN}

The above command consisting of upper-case and lower-case letters is the basic SPCI
syntax. The upper-case letters indicate the abbreviated spelling for the command. To shorten
program lines, you may use an abbreviated form. Generally, in order to create more readable
programs, it is best to use the complete form.

For example, via the above syntax statement, CURRENT and CURR are both available forms.
But when using unqualified and fragment forms, such as CUR and CURREN, an error will be
generated.

4.1.4 MIN and MAX Parameters

For many commands, the minimum/maximum values can be substituted by a parameter
MINimum/MAXimum. For example, in the following command:

CURRent {<current>|MIN|MAX}

To set the current limit to minimum value (0A), you can use the command CURR 0 or use
CURR MIN.

4.1.5 Setting and Querying Commands

Commands can group as setting commands and querying commands. Setting commands are
used to set value or state of the device. For example, VOLT 5 will set the CV limit to 5V.
Commands that ends with character ‘?’ are querying commands and you can use these
commands to query active setting values and states of the device. For example, VOLT? is
used to query the active CV limit value. In some querying commands, you can add
MIN/MAX/DEF parameters to query the minimum/maximum/default value of the setting. For
example, VOLT? MAX will return the maximum CV limit value of the power supply.

first, and want to read the second response, you may receive some data
from the first response followed by the complete second response. To
prevent this, do not send a query command without reading the
response. If the situation can’t be prevented, send a device clear before

Remote Control Reference

4.1.6 SCPI Command Terminators

A command string sent to the power supply has to end wit h a <new line> character. The
message from t he IEEE-488 EOI (end-or-identify) is analyzed as a <new line> character and
used to terminate a command string substituting a <new line> character. It’s also accepted
that a <carriage return> is followed by a <new line>. Command string termination alwa ys
reset the current SCPI command path to the root level. Generally, the <new line> char acter
has the ASCII decimal code of 10.

4.1.7 Common SCPI Commands

The GPIB (IEEE-488.2 standard) defines a set of common commands performing functions
like reset, self-test, and status operations. GPIB commands always start with an asterisk “*”,
consisting of 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. You can use a
semicolon “;” to separate multiple commands as shown below:

*RST; *CLS; *ESE 32; *OPC?

4.1.8 SCPI Parameter Types

The SCPI language defines several different data formats in order to be used in program
messages and response messages. Generally, these parameters are in numeric, discrete,
Boolean, and string.

Numeric Parameters:

Number-required commands accept commonly used decimal representations of numbers
such as decimal points and scientific notation. Some special numeric parameters like
MINimum, MAXimum, and DEFault are also accepted, as well as sending engineering unit
suffixes (V, A, or S) with numeric parameters. If you leave acceptable numeric values, the
power supply will round the input numeric parameters automatically. For example:

VOLT {<voltage>|MIN|MAX|UP|DOWN}

Discrete Parameters:

You can use discrete parameters to pro gram settings that have a limited number o f values like
BUS and IMM. When querying, responses will return the short form in all upper-case letters
invariably. For example:

TRIG:SOUR {BUS|IMM}

Boolean Parameters:

You can use Boolean parameters to represent a single binary condition that is either true or
false. If it’s a f alse c ondition, the power supply will accept OFF or 0. If it’s a true condition, the
power supply will accept ON or 1. When querying a Boolean setting, the power supply will
return 0 or 1 invariably. For example:

DISP {OFF|ON}

String Parameters:

4-3

Programmable DC Power Supply 62000L Series User’s Manual

String parameters contain virtually any set of ASCII characters. A string has to start and end
with matching quotes; either with a single quote or with a double quote. You can type it twice
without any characters in between to include the quote delimiter as part of the string. For
example:

DISP:TEXT <quoted string>

This command is used to set the CV/CC li mit values. I t is combination o f the co mmands VOL T
and CURR. If one of the voltage and current value are not in the valid data range, an error
occurs. The CV/CC limit values changes as soon as the command is executed.

Instead of entering voltage/current value, the parameters DEF/MIM/MAX are also acceptable.
MINimum and MAXimum set the voltage or current to the minimum and maximum available
value of the CC/CV limit levels. If a DEFault parameter is used, the CV/CC limit level stored in
the location 0 will be set.

If there is only one parameter following the APPLy command, the power s upply will use it to
set the CV limit.

APPLy?

This command is used to query the active applied CV/CC limit value. The CV/CC limit values
will return in the scientific format and separated by a comma.

OUTPut {OFF|ON}

This command is used to enable or disable the output of the power s upply. Aft er reset, the
output is always turned OFF.

If the output is turned OFF, 0is returned.

CURRent {<current>|MINimum|MAXimum|UP|DOWN}

This command is used to set the CC limit level of the power supply. If the output is turn ON,
this commands change the output of the power supply to the newly programmed CC limit
level.

The MINimum or MAXimum can be substituted for a specific value used on current. The
predetermined UP or DOWN parameter can be used to increase or decrease one step of the
CC limit level. The command CURRent:STEP describe below is used to set the amount of
increment and decrement step.

OVP trip level more greatly than the output setting.

MEASure[:VOLTage]?

This command is used to query the voltage output value measured by the power supply. The
reading value is returned in the scientific format.

4.2.2 Tri ggering Commands

The power supply under the triggering system allows a change in voltage and c urrent when
receiving a trigger. In addition, it also allows to you to select a trigger source, and to insert a
trigger. To trigger the power supply, you need to finish the following multi-step process.

 First of all, you have to specify the source from which the power supply wil l acc ept the

trigger. A bus (software) trigger or an immediat e trigger from the remote interface is
acceptable.

 After that, the time delay between the detection of the trigger on the specified trigger

source and the start of any corresponding output change is available to be set.

 At last, you have to provide an INITiate command. If selecting the IMMediate source, the

selected output will be set to the triggered level right away. However, if the trigger source
is the bus, your power supply will be set to the triggered level after receiving GET (the
Group Execute Trigger) or *TRG command.

The following commands are collected and used to deal with triggering. For more detailed
description, please check from the section 4.2.2.1 and 4.2.2.2

TRIGger[:SEQuence]
:DELay {<seconds>|MIN|MAX}
:DELay?
:SOURce {BUS|IMM}
:SOURce?
*TRG

.

4.2.2.1 Trigger Source Opti ons

You have to specify the source from w hich the power supply will accept the trigger. In addition,
the trigger is stored in volatile memory. And the source is set to bus after powering on the
power supply or resetting a remote interface.

Bus Triggering:

 Send TRIG:SOUR BUS to select the bus trigger source.
 Send *TRG to trigger the power supply via the remote interface, such as USB or GPIB

after selecting the bus source. When sending this command, the trigger acts after the
specified time delay if any delay is given.

4-8

Remote Control Reference

 Send a wait command *WAI to ensure synchronization once the bus source is selected.

When commanding *WAI, the power supply will wait for all pending operations to finish
before executing other additional commands. For example, the command, TRIG:SOUR
BUS; *TRG; *WAI; *TRG; *WA I guarantees that the first trigger is accepted and will be
executed before the second trigger is recognized.

 Use the operation complete query (*OPC?) or the operation complete (*OPC) command

to generate signal when the last operation is finished. Commanding *OPC? will return 1 to
the output buffer when the last operation is finished. Commanding *OPC will set the OPC
bit 0 in the Standard Event register when the operation is finished.

Immediate Triggering:

 Send TRIG:SOUR IMM to select the immediate trigger source.
 After selecting IMMediate as a trigger source, INITiate immediately transfers the

VOLT:TRIG or CURR:TRIG value to the VOLT or CURR value. All delay will be ignored.

4.2.2.2 Triggering Command Des cription

For new users, please read the command description carefully before commanding.
Incorrectly commanding the supply will result in no reaction.

INITiate

If the trigger source is IMMEDIATE, this comman d complete one full trigger cycle. If the t rigger
source is BUS, this command initiates the trigger system.

TRIGger:DELay {<seconds>|MINimum|MAXimum}

This command is used to set the time delay between the detection of an event on the
specified trigger source and the start of any c orresponding trigger action on the output. Select
from 0 to 3600 seconds, i.e. MIN = 0 seconds, and MAX = 3600 seconds. At *RST, the value
is set to 0 seconds.

TRIGger:DELay? [MINimum|MAXimum]

This query command is used to query the trigger delay.

TRIGger:SOURce {BUS|IMMediate}

This command is used to select the trigger source of the power supply. Either a bus trigger or
an internal immediate trigger will be accepted. At *RST, the bus trigger source is selected.

TRIGger:SOURce?
This query command is used to query the present trigger source, such as BUS or IMM.

*TRG

This command is used to generate a trigger to the trigger subsystem that has selected a bus
trigger as its source.

This section provides an overview of the basic techniques used to program the power supply
over the remote interface.

4.3.1 Regarding Programming Ranges

62000L series is a power supply with the auto range feature. You don’t have to set values
depending on the range. The available programming value for a parameter var ies ac cor ding
to the desired output range of the power supply. Please refer to the following table to identify
the programming values.

4.3.2 Regarding SCPI Status Registers

All SCPI devices utilize st atus registers in the same way. The status system can record
different kinds of condition groups, such as the Status Byte register, the Standard Event
register, and the Questionable Status register. For example, the Status Byte register records
high-level summary information which is reported in the other register groups. The following
diagram illustrates the SCPI status system used by the power supply.

4-18

Remote Control Reference

In addition, an event register is a read-only register that can generate defined conditions from
the power supply. Bits in an event register are under a locked status. Once an even bit is set,
the following status changes will be ignored. Bits in an event register are automatically
cleared by a query, such as *ESR?, STAT:QUES:EVEN? or *CLS. But sending *RST or
device clear won’t clear bits in event registers. Querying an event register will return a deci mal
value which conforms to the binary-weighted sum of all bits set in the register.

On the other hand, an enable register can define w hich bits in the cor responding even register
are ORed logically to form a single summary bit. Enable registers is able to read and write.
When querying an enable register, it won’t be cleared. Using *CLS can’t clear enable
registers, but it will clear the bits in the event registers. To enable bits in an enable register,
you have to write a decimal value which conforms to the binary-weighted sum of the bits that
you prefer enable in the register.

4.3.2.1 The Questionabl e Status Re gister

The Questionable Status register reports information about the power supply.
The bit 0 and bit 1 provides the information about the output CV/CC r egulat ion. If the power

supply is/was in CC (constant current) mode, the bit 0 sets to 1. If the power supply is/was in
CV (constant voltage) mode, the bit 1 sets to 1.

The bit 8 ~ bit 10 provides information that one of the protection event is tripped. If the over
temperature protection (OTP) tripped event is detected, bit 8 sets to 1. If the over voltage
protection (OVP) tripped event is detected, bit 9 sets to 1. If the over current protection (OCP)
tripped event is detected, bit 10 sets to 1.

To read the Questionable Status register, use the command below.
STATus:QUEStionable?.

Any or all of the Questionable Status Events can be reported in the Questionable Status
Summary bit (QUES, bit 3) of Status Byte register through the enable register. To set the
enable register mask, write a decimal value to the register using the following command.
STATus:QUEStionable:ENABle <value>.

4.3.2.2 The Standard Event Register

The Standard Event register reports the types of instrument events, such as power-on
detected, command syntax errors, command execution errors, self-test or calibration errors,
query errors, or when executing *OPC. All of these statuses can be reported in the Standard
Event summary bit 5 of the Status Byte register via the enable register. To set the enable
register mask, you have to use *ESE to write a decimal value to the register.

In addition, the Standard Event register will be cleared under the following conditions.

 Execute *CLS.
 Use *ESR? to query the event register. For example, 28 (4 + 8 + 16) is returned when the

status of the Standard Event register has been queried, and QYE, DDE, and EXE
condition have occurred.

In addition, the Standard Event Enable register will be cleared under the following conditions.

 Execute *ESE 0.
 Turn on the power supply, use *PSC 1 to configure the power supply.

4.3.2.3 The Status Byte Register

The Status Byte summary register can generate conditions from the other status registers.
Querying data that is waiting in the output buffer of the power supply is going to be
immediately generated through the “Message Available” bit (bit4) of the Status Byte register.
In addition, bits in the summary register are not locked. Clearing an event register will also
clear the corresponding bits in the Status Byte summary register. Reading all messages in the
output buffer and any pending queries will clear the message available bit.

When executing *CLS, the Status Byte summary register will be cleared. Using *ESR? to
query the Standard Event register will clear only bit 5 in the Status Byte summary register. For

In addition, the Status Byte Enable register will be cleared under the following conditions.

 Execute *SRE 0.
 Turn on the power and previously configured the power supply with *PSC 1.

4.3.2.3.1 Read Status Byte Request

The power supply implements a 488.2 USB488 interface and the host may read the Status
Byte summary register at any time with the READ_STATUS_BYTE request. If the power
supply receives a READ_STATUS_BYTE request from the host, an USB488 Interrupt-IN
packet as shown as the following table.

bTag value in the READ_STATUS_BYTE

4.3.2.3.2 Service Request (SRQ)

When the request service bit (RQS, bit 6) in the Status Byte is set, an USB488 Interrupt-IN
packet due to a SRQ condition is queued to send to the host. Select which summary bits will
generate the service request by setting the Status Byte enable register with *SRE command.

If the response is queued, the Status Byte is modified in the same way an IEEE-488.2 device
modifies the Status Byte after a SRQ/serial poll sequence. This means the power s upply will
clear the RQS bit of the Status Byte register after a Status Byte (with RQS set) is queued to
be sent on the Interrupt-IN pipe.

The request service (RQS) bit is cleared only by queuing a response Interrupt-IN packet due
to the SRQ condition or by reading the event register whose summary bit is causing the
service request.

In addition, the following procedures present how to generate an SRQ interrupt.

 Clear the output queue of the power supply.
 Use *CLS to clear the event registers.
 Use *ESE to set up the enable masks of Standard Event register. Use the command *SRE

4-22

Remote Control Reference

to set up the enable masks of the Status Byte summary register.

 Send *OPC? and enter the result to verify synchronization.
 Now, if any of the conditions corresponding to the enabled summary bits in the Status

Byte register occurs, the power supply send a USB488 Interrupt-IN packet as shown as
the above table to the hos t.

4.3.2.3.3 Use *STB? to Read the Status Byte

*STB? is used to query the Status Byte register. The return value while querying the Status
Byte register is a decimal value that corresponds to the binary-weighted sum of the bits set in
the register. Since the request service bit (RQS, bit 6) of the Status Byte register is reported
and cleared by a SRQ process, you don’t have to read the state of the RQS bit with *STB.
Executing *STB? can’t clear the Status Byt e summary register.

4.3.2.3.4 The Message Available Bit (MAV)

The Message Available bit (MAV, bit 4) of the Status Byte summary register indicates that
data in the power supply's output queue is available to read into USB bus. The MAV bit is
cleared only after all messages have been read from the output queue.

4.3.2.3.5 Use *OPC

The Operation Complete bit (OPC, bit 0) of the Standard Event register indicates if a
command sequence is completed. After a *OPC command is executed, the OPC bit of the
Standard Event regis ter is set . Send *OP C after a query command that loads message into
output queue, and you can use the OPC bit to determine if the message is available. However,
the output queue will fill and the power supply will stop processing commands if there are too
many messages generated by the commands before the *OPC executes sequentially.

In addition, the following procedures present how to determine if a command sequence is
completed.

 Clear the power supply's output queue.
 Use *CLS to clear the event registers.
 Execute *ESE 1 to enable the operation complete bit (OPC, bit 0) in the Standard Event

register.

 Send *OPC? and enter the result to ensue synchronization.
 Execute *OPC as the last command sequentially after the command string you use to

program the configuration of the power supply. The operation complete bit (OPC, bit 0) is
set in the Standard Event register when the command sequence is completed.

 Check the standard event bit (ESB, bit 5) in the Status Byte summary register to

determine if the command sequence is completed. The power supply will also generate a
SRQ interrupt if you configure it.

4-23

Error Messages

5. Error Messages

When a syntax or hardware error has been detected, the front-panel Err annunciator turns on
and the power supply beeps once each time an error is generated. A record of up to 32 errors
is stored in the power supply’s error queue.

Errors are retrieved in first-in-first-out (FIFO) order. The first error that was stored first is
returned first. The Err annunciator turns off when all errors stored in the error queue have
been read.

If more than 32 errors have been detected, the most recent error (the last error stored in the
queue) is replaced with -350, “Too many errors.” No additional errors are stored until you
remove errors from the queue. Reading the error message stored in the queue will remove it
at the same time. If no errors are stored when you read the error queue, the power supply
responds with +0, “No Errors” over the remote interface or NO ERROR from the front panel
operation.

When the power supply has been powered off or after a *CLS (clear status) command has
been executed, the error queue is cleared. The *RST (reset) command does not clear the
error queue.

On the other hand, if all of the error messages are from execution, Self-Test, and calibration,
then the following sections will describe which error code represents the status.

Front-panel operation:

Press the ERROR key repeatedly to read the errors stored in the queue if the Err annunciator is on.
The error is removed from the queue after being read by user.

Remote interface operation:

Use SYSTem:ERRor? to read the latest error message from the error queue. The returned
error messages have the 73 following format.

which sends data to the output buffer has not been received. For example, you may have
executed an APPLy command (which does not generate data) and then attempted an ENTER
statement to read data from the remote interface.
