Safety Precautions
Failure to comply with the precautions below could lead to injury or death or
damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
The GS200 is a generator that can generate DC voltage and current. Do not use
this instrument for anything other than as a DC voltage and current generator.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged into an outlet with
a protective earth terminal. Do not disable this protection by using an extension
cord without protective earth grounding. Additionally, do not use the power cord
supplied with this instrument with another instrument.
Do not use the power cord in a bundled condition. If you use a power plug with
foreign substance on it, insulation may be compromised by humidity or other
factors and may cause a fire. Clean the power plug regularly.
Connect the Protective Grounding Terminal
Be sure to connect the protective earth to prevent electric shock before turning ON
the power. The power cord that comes with the instrument is a three-prong type
power cord. Connect the power cord to a properly grounded three-prong outlet.
Do Not Impair the Protective Grounding
Never cut off the internal or external protective earth wire or disconnect the wiring
of the protective earth terminal. Doing so poses a potential shock hazard.
Do Not Use When the Protection Functions Are Defective
Before using this instrument, check that the protection functions, such as the
protective grounding and fuse, are working properly. If you suspect a defect, do not
use the instrument.
Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable gasses or vapors.
Operation in such an environment constitutes a safety hazard.
Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel may remove the covers and disassemble or
alter the instrument. The inside of the instrument is dangerous because parts of it
have high voltages.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the item under
measurement or to an external control unit. Before touching the target device, turn
off this instrument and check that there is no voltage or current being output.

GS200 Features
• The GS200 uses dual D/A conversion to produce voltage and current with high
accuracy and resolution. It can produce stable current or voltage whether it is used for
a short or long period of time and maintains superb linearity over all the ranges. You
can also use the GS200 to produce voltage and current that has low noise.
• The GS200 can perform four-quadrant operation by operating as a current source or a
current sink in the range of ±32 V and ±200 mA.
• The GS200 has an optional voltage and current measurement feature (monitoring
feature). The GS200 can measure current in voltage source mode and measure
voltage in current source mode. The display resolution is 4½ digits.
• By using the program feature, you can specify up to 10000 steps, each of which
controls the generation of voltage or current. You can also generate ramp waveforms
by using the slope setting.
• You can use the external I/O BNC connector on the rear panel to control multiple
GS200s or other measuring instruments by synchronizing them to actions such as the
source action and the output action.
• The I/O terminals for synchronous operation (SYNC IN/OUT) of multiple GS200s can
be connected in a daisy chain to allow synchronization of output control and triggers.
This increases the number of channels that can be controlled.
• The GS200 has a built-in 4 MB non-volatile storage disk (GS200ROM) for storing
various settings and a 16 MB volatile storage disk (GS200RAM) for storing data such
as measurement results. If you use USB to connect the GS200 to a PC, you can
access these storage disks as the PC’s external drives. Because settings and results
are saved to general text files or .CSV files, you can use software such as a text editor
or a general-purpose spreadsheet application to edit these files or use them to display
graphs on your PC.
In addition to the storage feature, the USB interface can be used to perform command
control by way of the USB-TMC protocol. Furthermore, command control can be
performed by way of other communication interfaces such as GP-IB, and Ethernet
(VXI-11 protocol/7655 command socket).
You can also use the Ethernet interface to access the GS200’s internal disks through
FTP (the FTP server feature) and to display the GS200’s information and control
it from a Web browser by accessing the GS200 through HTTP (the HTTP server
feature).

2
Features
This section explains the basic features of the GS200: the source feature and the
measurement feature (monitoring feature).
3
Generating Voltage and Current
The GS200 uses dual D/A conversion and a highly accurate power amplifier. This
enables you to set the voltage and current at a resolution of 5½ digits.
4
Voltage Source
The GS200 has 10 mV, 100 mV, 1 V, 10 V, and 30 V ranges. You can specify and
generate a positive or negative voltage of up to 32 V.
5
Current Source
The GS200 has 1 mA, 10 mA, 100 mA, and 200 mA ranges. You can specify and
generate a positive or negative current of up to 200 mA.
6
The 1 V, 10 V, and 30 V voltage source ranges enable you to generate a positive or
negative output current of up to 200 mA with a low output resistance. These ranges are
well-suited to situations such as the evaluation of devices that require current.
When you select the 10 mV or 100 mV range, the GS200 uses a voltage divider that
consists of a pair of resistors. This enables you to use the GS200 to generate low
voltages at resolutions as low as 100 nV or as a 3 μVp-p*, low-noise voltage signal
source. These ranges are well-suited to providing simulated signals to instruments such
as sensors.
In current source mode, you can generate a positive or negative output voltage of 30 V
on all of the current ranges. Current source mode is well-suited to evaluating the charge/
discharge characteristics of rechargeable batteries and other devices.

2.2 Source Feature and Measurement Feature (Monitoring feature; /MON option)
Source and Sink Operations
The GS200 can perform four-quadrant operation by operating as a current source or a
current sink in the range of ±32 V and ±200 mA.
During sink operation, the GS200 operates in the same quadrants as it does during
source operation, so you can use it not just as a true constant voltage source but also as
a highly accurate electronic load.

Maximum output current:

Bipolar Output
Because the GS200 inverts the signal polarity and produces the signal without the use
of a mechanical contact, no abnormal voltage (or current) is generated when the polarity
is inverted. Therefore, the GS200 can generate continuous, variable output ranging
from the maximum negative value to the maximum positive value. This is effective when
you want to invert the polarity to generate program output or evaluate zero-crossing
comparators. Additionally, when you change settings within the same range, glitches are
not generated.

* In voltage source mode’s 10 mV and 100 mV ranges, because the GS200 uses a voltage
divider, the output resistance is approximately 2 Ω. Therefore, these ranges are not suitable
when the GS200 is connected to a load that allows current to flow (a low-impedance
load). Depending on the load current, the output voltage may decrease. Also, four-terminal
connection does not function for these voltage ranges. You must use the two-terminal
connection instead. Connect a high-impedance load, a load that is sufficiently larger than the
output resistance.

The source function can be set to either voltage (V or mV) or current (mA).
Voltage (V):Operates as a constant voltage source. The current limiter is enabled.
Voltage (mV): Operates as a voltage source that uses a voltage divider.
Current (A):Operates as a constant current source. The voltage limiter is enabled.

Source action refers to the setting of the source level and the way that the source level
changes to the new value. In source actions, various control signals change as shown
below.
11
During DC Source Operation (When a program is not running)
The actual source level will change at the time the setting change is instructed from a
panel operation or communication command. The source change completion (Ready)
signal, which is a low-level pulse signal with a width of 10 μs, is generated 10 ms after
the source level changes. Additionally, the trigger busy (TrigBusy) signal, which indicates
the program execution status, remains at high level and does not change.

During Program Execution
When you execute a program, the trigger busy signal is set to low level, and the source
level changes. The source change completion (Ready) signal, which is a low-level pulse
signal, is generated 10 ms after the source level changes. When each program interval
time completes, the trigger busy signal is set to high level. The program proceeds from
step to step by repeating this pattern.

Output ON/OFF
(See section 5.5 for the procedure)
There are two output modes: OFF or ON.
OFF:The output is disconnected, and the specified source level is not generated. In
this mode, program and measurement functions are disabled.
ON:The output is connected, and the specified source level is generated. In this
mode, program and measurement functions are enabled.
Note
A mechanical relay operates when the GS200 switches between output on and output off. Note
the following points when using the GS200.
• It takes approximately 20 ms for the relay to stabilize.
• As the number of on/off operations increases, effects begin to appear such as the relay
taking longer to stabilize. Though dependent on the load, the electrical life of the relay is
around 100,000 operations.
DUT Protection Using Limiters
(See section 5.4 for the procedure)
CAUTION
If a current source that exceeds the current limiter setting is connected in voltage
source mode; if a voltage source that exceeds the voltage limiter setting is
connected in current source mode; or if a load that exceeds the source range listed
above is connected, an abnormal load is detected, and the output is turned off (the
output trips). Do not connect these types of loads to the GS200. Doing so may
damage the instrument.

Tripping the Output
If the GS200’s output exceeds the high limiter or falls below the low limiter, the output
is automatically turned off. If this occurs, the error indicator illuminates, and the event is
written to the error log.
Local Sense and Remote Sense
(See section 4.2 for the procedure)
Guard Terminal Feature
(See section 4.3 for the procedure)
Two wiring systems, 2W (two-terminal connection or local sense) and 4W (four-terminal
connection or remote sense) are available. In voltage source mode, when the current
flowing through the load becomes large, the voltage drop in the lead wire can no longer
be ignored. If this occurs, you can select the four-terminal connection and connect the
SENSE terminal near the DUT so that the voltage at the connected location is adjusted
to the specified voltage. This alleviates the effects from lead wire resistance, and the
desired voltage can be applied to the DUT.
If the GS200 and the DUT are far apart or if the GS200 shares its power source with
electric motors, common mode noise may be superimposed on the power source signal
supplied to the DUT. If common mode noise is superimposed on the signal between the
GS200’s Hi and Lo terminals, the noise current enters the internal source circuit from
the output terminals and changes the generated signal. To reduce this effect, a shield
for the source circuit is connected to the guard terminal of the GS200. If you connect the
noise source to the guard terminal, the noise current passes through the guard and is
grounded, bypassing the internal source circuit. This reduces the amount of noise that
enters the circuit from the connected power source. Use the guard terminal when a large
amount of common mode noise is superimposed on the power source signal.

Programs
(See section 6.1 for the procedure)
The program feature enables you generate the source data pattern that you specified
as a program in advance. Each step in the program is executed in order, and each step
has a fixed execution time. You can also set the slope time, so you can generate step
responses, ramp responses, and various waveforms such as triangular waveforms.
To create and load programs you can:
• Create and edit programs from the GS200 screen.
• Create programs on a PC, save them to the GS200’s internal memory (GS200ROM)
as program files in CSV format, and load them from the internal disk.
Source data that programs can contain:
• The source level.
• The source range.
• The source function.
(See section 6.2 for the procedure)

Program Triggers
(See section 6.4 for the procedure)
If you specify to repeat programs, after the last step in a program finishes, the first step in
the program begins executing.
Depending on the program trigger setting, there are the following two types of program
operation.
When Program Triggers Are Set to Normal (Norm)
You can use the RUN, STEP, and HOLD keys and external triggers to control the
program execution.
RUN key: Executes the program from step 1.
STEP key:Executes only one program step.
HOLD key:Pauses the program execution or resumes execution of a paused program.
The program interval time specifies the execution interval for each step in the program.
When Program Triggers Are Set to Measurement End (M.End; only on
models with the /MON option)
The program executes the source and measurement operations of each step in the
minimum time required. The RUN, STEP, and HOLD keys and external triggers are
disabled. Additionally, the program interval setting is ignored.

Line
A line is a string of text that is delimited with line-feed codes (LF or CR+LF). Each line
defines the following items (from left to right).
• The source level:Defined with an integer or a real number.
Examples: 1, 0.485, –12E–3
• The source range:Defined with an integer or a real number.
Examples: The same as the examples given above.
• The source function: Defined with a character (V or I).
Make the program file a .CSV file by using a separator (choose either a comma or
a semicolon) to separate each item. You can also include white space (space or tab
characters) before and after each item.
You can omit the source range and source function. If any items are omitted, the same
item from the previous step is used. If the source function is not defined in the program’s
first step, the source function that the GS200 was using when the program file was
loaded is used. If the source range is not defined in the program’s first step, the source
range is set to the most appropriate range for the source level that is defined in the
program’s first step.
Comments
You can include comments in program files. A comment consists of any text between “//”
and a line-feed code or the end of the file. The GS200 ignores comments when it loads
program files.

The low pulse that indicates source change completion (Ready) is generated 10 ms after Ts elapses.
HOLD and STEP
When you press the HOLD key to pause program execution, the paused step is said
to be in the “mid-execution” state. If you press the STEP key while the GS200 is in this
state, the current step that was in the mid-execution state is re-executed. When this step
completes, the GS200 pauses the program again. If, on the other hand, you press the
HOLD key while the GS200 is in this state, the GS200 continues program execution from
the point that it was paused in the step that was in the mid-execution state.
For example, assume that we have a program that begins at 0 V and ends at 10 V. Each
step specifies an increase of 1 V, and a step is executed each second. Now assume that
we execute the program and press HOLD when 4 V has been generated for only 0.5
seconds.
• If the STEP Key Is Pressed
The GS200 does not generate 5 V as specified by the next step, but rather generates
4 V for 1 second as specified by the step that was in the mid-execution state, and then
pauses execution again. If you press the STEP key once more, 5 V is generated for 1
second, and then the program execution is paused again.
2-14
IM GS210-01EN
2.4 Programs
• If the HOLD Key Is Pressed
The GS200 generates 4 V for the remaining 0.5 seconds as specified by the step
that was in the mid-execution state, generates 5 V for 1 second, and then continues
executing the rest of the program.
When measurement completes, the GS200 proceeds to the next step in the program and
changes the source level. If you set the program trigger to measurement end (M.End),
and the measurement trigger to source change completion (Ready), the program
executes the source and measurement operations of each step in the minimum time
required.
The RUN, STEP, and HOLD keys and external triggers are disabled. Additionally, the
program interval setting is ignored.

Measurement is performed. The measured value is displayed in the upper-left section of
the screen.
Note
When you turn measurements on, noise may be superimposed on the source output depending
on the operation of the GS200 internal measurement circuit. To reduce noise in the source
output, turn measurements off.
Measurement Operation
Measurement operation refers to a sequence of measurements that is carried out as a
result of a measurement trigger. Measurement begins after a measurement trigger is
received and the specified measurement delay elapses. For information on triggers, see
section 2.6. For information on measurement delay, see the next page.
The overall process of the measurement operation is described in steps 1 to 3 below.
1.Measurement
The GS200 performs the target measurement. The time required for measurement is
the sum of the integration time and the software processing time.
2. Zero Reference Measurement
The GS200 performs the zero reference measurement. The time required for the zero
reference measurement is the sum of the integration time and the software processing
time.
3. NULL Computation (See the next page)
The GS200 subtracts the NULL reference value from the measured value and makes
the difference the result. If NULL computation is OFF, nothing is performed.

2.5 Measurement (Monitoring feature; /MON option)
Note
• If you change GS200 settings while measurements are being performed, those
measurements are invalid. The measured result display shows “-----,” and you cannot store
the results.
• Software processing time is less than 1 ms.
(See section 7.3 for the procedure)
Measurement delay is the wait time from when a measurement trigger is applied to
when the measurement operation is carried out. You can adjust the timing between
the measurement trigger and the measurement operation by changing this setting. For
example, you can set the time needed for the DUT to stabilize after source change
completion to the measurement trigger, so that measurement is performed when the
DUT has stabilized.
Highly Accurate Measurement and High-Speed Measurement
Depending on the settings, the following measurement conditions enable you to perform
highly accurate measurements or high-speed measurements.
Local Sense and Remote Sense
(See section 4.2 for the procedure)
Two wiring systems, 2W (two-terminal connection or local sense) and 4W (four-terminal
connection or remote sense) are available (see page 2-10). When the DUT allows a large
output current to flow, the voltage drops due to wire resistance. 4W is effective in this
kind of situation. In voltage source mode, you can minimize the effect of wire resistance
and measure the voltage that is applied to the DUT. In current source mode, you can
minimize the effect of wire resistance and measure the voltage that the DUT generates.
Integration Time
(See section 7.2 for the procedure)
An integrating A/D converter is used for measurements. If you set a long integration time,
the measurement takes longer, but the stability of the measured values increases.

Offset Calibration Feature
Zero Calibration (Manual Zero) Feature
(See section 7.7 for the procedure)
If zero calibration is executed from the GS200’s operation menu, output is automatically
turned off, the zero reference is measured, and the zero reference is applied to
subsequent measured results. The zero point may change due to the passage of time,
the GS200 being in an environment where the temperature changes drastically, or due to
other factors. By executing zero calibration, the zero point is calibrated, and this enables
the GS200 to generate more accurate output.
NULL Computation

(See section 7.6 for the procedure)
In NULL computation, the GS200 can display a difference from a given measured

subtracting this NULL value.

Storing Measured Results
(See section 7.8 for the procedure)
This feature enables you to save the specified number of measured results to storage
memory. You can specify a storage count in the range of 1 to 10000. If the storage
operation is aborted before the specified storage count is met, the measured results
up to that point are stored. If the stored result file generation feature is turned on, the
stored results are saved to a result file (Result.csv) in the built-in GS200RAM (see
“USB Storage Feature” on page 2-25) when storage completes. If the stored result file
generation feature is off, the stored results are not saved to a file. In this case, use the
communication feature to read the measured results.
Performing Statistical Computations on Measured Values (Recall)
(See section 7.9 for the procedure)
The statistical computation results of the most recent measured values in the storage
memory can be displayed. The statistical computation parameters are the storage count,
maximum value, minimum value, maximum value – minimum value, mean value, and
standard deviation.

Result File
(See section 7.8 for the procedure)
The result file (Result.csv) contains the measured results that have been stored in
storage memory. It is generated by the stored result file generation feature and is saved
to the internal GS200RAM. Each entry in the result file contains the elapsed time from
the start of the first measurement operation (a timestamp), the source function, the
measurement function, the source level, and the measured value.
Example of a Result File
Timestamp

The name of the most recent result file is always Result.csv. Up to 33 result files are
stored on the GS200RAM. Less files are stored if their size exceeds the memory limit
(16 MB). When the storage operation is repeated, the names of existing result files are
changed automatically. For example, if two storage operations are completed, the most
recent file will be Result.csv, and the previous result file will be changed to Result.01.csv.
If the storage operation is repeated further, the name of a result file will be changed as
follows: Result.csv, Result.01.csv, Result.02.csv, Result.03.csv, and so on. If the number
of result files exceeds 33, the files are deleted in order from the oldest file. However,
if deleting the oldest file does not clear sufficient space to make room in the internal
GS200RAM for the new result file, multiple result files may be deleted.

Overview
Program Triggers
The GS200 uses program triggers, which are used to start and pause programs, and
measurement triggers, which are used to start measurements.
(See section 6.4 for the procedure)
This trigger is used to drive programs (see section 2.4). On models with the monitoring
(/MON) option, you can select the normal (Norm) or measurement end (M.End) trigger
source. On models without the monitoring (/MON) option, only the normal (Norm) trigger
source is available.
Normal (Norm)
You can use the following four triggers to execute programs.
• RUN key
Press this key to begin program execution from step 1. The program proceeds one
step each time the program interval time elapses.
• STEP key
Press this key to execute only the current step. When the program interval time
elapses, program execution stops.
• HOLD key
Press this key to pause the program that is running. If you press this key when a
program is paused, program execution begins again from the exact point in the step
that it was previously paused.
• External triggers (External)
The falling edge of a signal applied to TRIG IN of the input terminal for synchronous
operation (SYNC IN, see section 8.2) or TRIG IN of the BNC I/O terminal (see section
8.1) on the rear panel is used as a trigger. This trigger performs the same function as
the STEP key on the front panel.
Measurement End (M.End; only on models with the /MON option)
When the trigger source is set to measurement end, program execution proceeds from
one step to the next as soon as the current step’s measurement completes, regardless of
the program interval time. You can execute programs at their optimal speed, but program
execution always requires the specified integration time (measurement time). However,
you have to set the measurement trigger to source change completion (Ready).
When the program trigger is M.End, the RUN, STEP, and HOLD keys are disabled, and
the program interval time is ignored.

2.6 Triggering
Trigger Output
(See sections 8.1 and 8.2 for the procedures)
The GS200 can output the program trigger signal from the SYNC OUT terminal (I/
O terminals for synchronous operation) or the BNC output terminal to the subsequent
GS200s that are connected.
Trigger Hold
Sampling Error
You can pause program execution by pressing the HOLD key on the front panel or by
transmitting the communication command “:PROGram:HOLD” or “:PROGram:PAUSe.” To
resume program execution, press the HOLD key again, or transmit the communication
command “:PROGram:HOLD” or “:PROGram:CONTinue.”
If one of the following invalid triggers occurs, the sampling error indicator on the front
panel illuminates.
• A new measurement trigger occurred while a measurement operation was in progress.
• The RUN or STEP key was pressed or an external trigger signal was received while a
program was running.
Note
If sampling errors occur, the trigger generation timing may be too fast. If the sampling error
indicator illuminates, check settings such as the selected trigger source and timer period.
2
Features
TrigOut
TrigOut transmits the trigger busy signal.
• When program triggers are set to normal (Norm)
When a program trigger is generated, this signal is set to low level. When the program
interval time elapses, this signal is set to high level.
• When program triggers are set to measurement end (M.End)
When a program trigger is generated, this signal is set to low level. Regardless of the
program interval time, this signal is immediately set back to high level.

Synchronization
Synchronization
External I/O
You can connect multiple GS200s and synchronize switching of the output between on
and off and their program execution.
There are two types of external I/O terminals on the GS200: the I/O terminals for
synchronous operation (SYNC In/OUT) and the BNC I/O terminals (IN and OUT).
RJ-11 Connector (I/O terminals for synchronous operation; SYNC IN/OUT)
(See section 8.2 for the procedure)
By using the I/O terminals for synchronous operation (SYNC IN/OUT) on the rear panel,
you can synchronize the operation of multiple connected GS200s. Use synchronous
operation cables (758960) that are sold separately to connect the GS200s in a daisy
chain. The first unit is connected to the second unit, the second unit is connected to the
third unit, and so on. You can synchronize the operation of program triggers and the
output state (output on and off).
BNC I/O (IN and OUT)
(See section 8.1 for the procedure)
You can use the BNC connectors at the top of the rear panel to apply and transmit any of
the following signals as external signals. You can use these connectors for synchronous
operation and other purposes.
• Output state (output on and off) I/O
• Program trigger I/O
• Source change completion (Ready) output

Other Features
(See section 4.4 for the procedure)
The GS200’s internal memory consists of a 4 MB non-volatile disk (GS200ROM) and
a 16 MB volatile disk (GS200RAM). If you use a USB cable to connect the GS200 to
a PC, you can access these disks from the PC as removable disks. You can store the
program files that you have created using a general-purpose spreadsheet application to
the GS200ROM non-volatile disk simply by dragging the files from the location they are
stored on the PC.
The volatile disk (GS200RAM) stores measured results. If you load the measured result
file on your PC, you can use a general-purpose spreadsheet application to edit the data
or display the data as graphs. The system file that is used to update the GS200 system
is also stored on this disk.

2.8 Other Features
PROGRAM
This folder contains all the program output pattern files. All the files in this folder can be
used as program files.
When the GS200 is sent from the factory, two sample program files are stored in this
folder. These sample program files are also created when you format the disk.
SETUP
This folder contains all the panel setup files. Any of the files in this folder can be selected
as a setup file.
When the GS200 is sent from the factory, a sample setup file is stored in this folder. This
sample setup file is also created when you format the disk.
Volatile Disk (GS200RAM)
The GS200RAM is a volatile disk. When you turn the GS200 on, this disk is automatically
formatted. During storage, the result file (Result.csv) is created on this disk.
This disk is normally used to transfer files that the GS200 generates to your PC.
However, a system file is transferred from your PC to this disk when you update the
system firmware. For details, see section 14.5, “Updating the System Firmware.”
Note
You can create files and folders on the GS200RAM, but be sure that the disk does not become
full. The data on this disk is lost when the GS200 is turned off.
Formatting the Disk
You can format the disk if you want to reset the GS200ROM to the factory default
conditions, if the non-volatile or volatile disk cannot be detected by your PC, or if you
believe the data on the disk is corrupt.
USB Communication (USB-TMC command control)
(See chapter 10 for the procedures)
The GS200 has a USB2.0 device interface. This interface allows access to the USB
storage feature as well as allows command control from a VISA (Virtual Instrument
Software Architecture) library using a VISA USB-TMC device driver as defined by the VXI
Plug&Play System Alliance.
2-26
IM GS210-01EN
2.8 Other Features
Ethernet Communications (/C10 option)
(See chapter 11 for the procedures)
The GS200 has a LAN interface with auto switching between 10 Mbps and 100 Mbps.
You can assign a static IP address or obtain an address dynamically from a DHCP
server. The following four features are available.
The GS200 has an Ethernet VXI-11 device driver. This allows command control from a
VISA library.
Panel Control Using a Browser
(See section 11.5 for the procedure)
The GS200 has a Web server feature. This allows you to display the front panel image
of the GS200 on a PC’s Web browser and remotely control the GS200 from the Web
browser.
File Transfer with FTP Clients
Up to five clients can establish FTP connections by way of the anonymous FTP server
function. The non-volatile disk (GS200ROM) and volatile disk (GS200RAM) can
be handled as a PC file server. Files such as program files can be transferred, and
measured result data can be loaded onto a PC through the use of the FTP protocol.
For information on the GS200ROM and GS200RAM, see “USB Storage Feature,” on
page 2-25.
Command Control Using Port 7655
The GS200 has a command mnemonic stream parsing server that can connect up to five
clients. The terminator (CR, LF, or CR+LF) can be specified.
Because each server feature is independent, you can for example, control the GS200
using commands while it is transferring files using FTP.
GP-IB Communications
(See chapter 12 for the procedures)
The GS200 has an interface that is used to control the GS200 using commands. You
can specify the same settings as you would using the front panel keys of the GS200 and
output setup data and measured data. Because the command control of the GS200 is
mutually independent, other communication features can be used while you are using
GP-IB to control the GS200.
Saving, Loading, and Deleting Setup Data
(See section 9.2 for the procedure)
The current settings can be saved to a setup file (Setup01.txt to Setup04.txt) on the nonvolatile disk (GS200ROM). The saved setup data can be loaded to restore the settings.
The setup file is a text file that contains communication commands. This file can be
edited later on your PC.
For information on the GS200ROM and GS200RAM, see “USB Storage Feature,” on
page 2-25.
Selecting the Settings Applied at Power-On
(See section 9.3 for the procedure)
The GS200 settings at power-on can be changed from the default settings to the settings
selected by the user.
If the selected file is deleted or renamed, the GS200 will start with its default settings.

Correct the Problem If Output Is Forcibly Turned Off
If the GS200 detects an internal circuit error due to an excessive external input or
electrical oscillation, the output is forcibly turned off, the ERROR indicator illuminates,
and the error message “An abnormal load is connected” is displayed. If this happens,
remove the cause of the problem, such as the external load, and turn the output on
again. If the output still turns off after you have corrected the problem, the GS200 may be
malfunctioning. Contact your nearest YOKOGAWA dealer. Note that even if the GS200 is
returned to normal, the error display remains until you manually clear it (see section 9.6,
“Error Log Display”) or use communication commands to read the error information.

• Do not use cables whose conductive parts are exposed due to tears in the
insulation or broken cables as they may lead to a short circuit or electric shock.
• Do not connect a voltage source in voltage source mode or a current source in
current source mode. An incorrect connection may damage the GS200.
• Do not connect a load that exceeds ±32 V or ±200 mA across the OUTPUT Hi
and OUTPUT Lo terminals or across the SENSE Hi and SENSE Lo terminals.
• The maximum allowable voltage between the case and each terminal is ±250
Vpeak. Applying a voltage that exceeds this value may damage the GS200.
• Keep the voltage that is generated across OUTPUT Hi and SENSE Hi and
across OUTPUT Lo and SENSE Lo to less than or equal to ±0.5 Vpeak.
• When making a four-terminal connection, be careful that the connection to
the SENSE terminals does not get cut. If the voltage is not sensed correctly,
abnormal voltage may be generated across the OUTPUT Hi and OUTPUT Lo
terminals.
• When making a two-terminal connection, use the OUTPUT terminals. If the
SENSE terminals are used, the current flows through the SENSE line. This
prohibits the GS200 from generating correct output and can damage the GS200.
• If you are using the instrument in a floating condition and there is a risk of
dangerous voltage, only use lead wires that have safety terminals that cover
their conductive parts. Using a terminal with bare conductive parts (such as a
banana plug) can be dangerous if the terminal comes loose.
• If you are using the instrument in a floating condition and there is a risk of
dangerous voltage, do not use the fork terminal adapter set 758921. Due to the
structure of the product, it is possible to touch the metal parts of the fork terminal
adapter 758921. Be careful as this constitutes an electric shock hazard.
• Use the accessories of this product within the rated range of each accessory
(see page v). When using several accessories together, use them within the
specification range of the accessory with the lowest rating.

Instrument Preparation and Common Operations
Before Wiring
• Ground the instrument before connecting the instrument to the target device.
The power cord that comes with the instrument is a three-prong type power
cord. Insert the power cord into a grounded three-prong outlet.
• Be sure to turn the GS200 output off before you connect the device that you are
generating output for.

3.5 Wiring Precautions
• To prevent oscillations due to stray capacitance and lead inductance, use
twisted-pair lead wires to connect to the OUTPUT Hi and OUTPUT Lo terminals.
Likewise, use twisted-pair lead wires to connect to the SENSE Hi and SENSE Lo
terminals. In particular, wire the lead wires short in the case of a high-capacity
load in a four-terminal connection in voltage source mode.
• When using the 10 mV or 100 mV range, do not apply external voltage or
current. Also, do not connect to charged capacitive loads.
If you output high voltage or if the voltage limiter is activated while outputting
current when a capacitive load is connected, be careful as the capacitor will be
charged with high voltage. Applying external voltage or current may damage the
voltage divider inside the GS200.

AVERTISSEMENT
Avant le câblage
• Relier l’instrument à la terre avant de le brancher sur l’appareil cible. Le cordon
d’alimentation livré avec l’instrument est doté de trois broches. Brancher le
cordon d’alimentation sur une prise de courant à trois plots mise à la terre.
• Veillez à mettre le GS200 hors tension lorsque vous connectez le dispositif à
tester.
Câblage
• Utilisez seulement des câbles en plomb dont les pièces conductrices
sont recouvertes pour un raccordement aux bornes de sortie. Des pièces
conductrices exposées peuvent entraîner une choc électrique.
• N’utilisez pas de câble de plomb dont les pièces conductrices sont exposées,
en raison de traces d’usure de l’isolation ou de câbles cassés, car ceci risque
d’entraîner un court-circuit ou un choc électrique.
• Ne raccordez pas une source de tension en mode source de tension ou une
source de courant en mode source de courant. Un raccordement incorrect
risque d’endommager le GS200.
• Ne connectez pas une charge supérieure à ± 32 V ou ± 200 mA entre les bornes
OUTPUT Hi et OUTPUT Lo ou entre les bornes SENSE Hi et SENSE Lo.
• La tension maximale autorisée entre le boîtier et chacune des bornes est
de ±250 Vcrête. L’application d’une tension dépassant cette valeur risque
d’endommager le GS200.
• Maintenez une tension entre les bornes OUTPUT Hi et SENSE Hi et OUTPUT
Lo et SENSE Lo inférieure ou égale à ±0,5 Vcrête.
• Lors d’une connexion aux quatre bornes, veillez à ce que la connexion aux
bornes SENSE ne soit pas coupée. Si la tension n’est pas correctement
détectée, une tension anormale est générée entre les bornes OUTPUT Hi et
OUTPUT Lo.
• Lors d’une connexion à deux bornes, utilisez les bornes OUTPUT. Si vous
utilisez les bornes SENSE, les courants circulant dans la ligne SENSE
empêchent le GS200 de fonctionner normalement et entraînent des dommages.
• Si l’instrument est utilisé en condition de flottement et qu’un risque de tension
dangereuse est présent, n’utiliser que des câbles en plomb dotés de bornes
sécurisées capables de couvrir les éléments conducteurs. L’utilisation d’une
borne dotée d’éléments conducteurs nus (comme une fiche banane) serait
dangereuse si la borne venait à se détacher.
3-12
IM GS210-01EN
3.5 Wiring Precautions
ATTENTION
• Utiliser des câbles de mesure dont la rigidité diélectrique et la capacité de
courant conviennent pour la tension ou le courant à mesurer.
• Pour éviter les oscillations liées à la capacité parasite et à l’inductance des
câbles en plomb, utilisez des câbles en plomb à paire torsadée pour les
connexions aux bornes OUTPUT Hi et OUTPUT Lo. De même, utilisez des
câbles en plomb à paire torsadée pour les connexions aux bornes SENSE Hi et
SENSE Lo. En cas de charge de haute capacité, branchez les câbles en plomb
pour une connexion à quatre bornes et en mode source de tension.
• Ne pas appliquer de tension ou de courant extérieur si la plage 10 mV ou
100 mV est utilisée. Ne pas connecter à des charges capacitives chargées.
Si vous générez une haute tension ou si le limiteur de tension est activé lors de
la sortie de courant lorsqu’une charge capacitive est connectée, veillez à ce que
le condensateur soit chargé à haute tension. L’application d’une tension ou d’un
courant extérieurs peut endommager le diviseur de tension du GS200.
Note
Susceptibility to the effects of noise increases when sourcing or measuring minute currents.
Take measures such as using shielded wires. Grounding shielded wires is an effective measure
to reduce the effect of noise.

• When making a four-terminal connection, be careful that the connection to
the SENSE terminals does not get cut. If the voltage is not sensed correctly,
abnormal voltage may appear across the OUTPUT Hi and OUTPUT Lo

AVERTISSEMENT
• Lors d’une connexion aux quatre bornes, veillez à ce que la connexion aux
bornes SENSE ne soit pas coupée. Si la tension n’est pas correctement

• Lors d’une connexion à deux bornes, utilisez les bornes OUTPUT. Si vous
utilisez les bornes SENSE, le GS200 n’est pas capable de générer correctement
la tension ou le courant, et risque de provoquer un court-circuit.
When the GS200 is measuring voltage in current source mode and the current becomes
large, the voltage drop in the lead wire can no longer be ignored. In such a case, you
can measure the voltage with reduced effects of the lead wire resistance by selecting the
four-terminal connection (4W) and connecting the SENSE terminals near the DUT. The
effects of the lead wires also appear in voltage source mode. In this case as well, using
the four-terminal connection (4W) enables the GS200 to apply the specified voltage to
the DUT with reduced effects of the lead wire resistance.

Note
• If 4W (four-terminal connection) is used, the source voltage across the OUTPUT Hi and
OUTPUT Lo terminals will be larger than the voltage generated on the load. If the voltage
across the OUTPUT-SENSE terminals exceeds 0.5 V, the GS200 will not be able to
generate the voltage correctly, and abnormal load detection may be activated and cause the
output to turn off. Be sure that the voltage across the OUTPUT-SENSE terminals does not
exceed 0.5 V.
• The four-terminal connection does not function for the 10 mV and 100 mV ranges in voltage
source mode. You must use the two-terminal connection instead. Because the output
resistance is approximately 2 Ω for these voltage ranges, they are not suitable when the
GS200 is connected to a load that allows current to flow (a low-impedance load). Connect a
high-impedance load, a load that is sufficiently larger than the output resistance.
• To prevent oscillations due to stray capacitance and lead inductance, use twisted-pair lead
wires to connect to the OUTPUT Hi and OUTPUT Lo terminals. Likewise, use twisted-pair
lead wires to connect to the SENSE Hi and SENSE Lo terminals. In particular, wire the
lead wires short in the case of a high-capacity load in a four-terminal connection in voltage
source mode.

4.3 Setting the Guard Terminal
Explanation
If common mode noise is superimposed on the signal passing through the GS200’s
output terminals, the noise current enters the internal source circuit from the output
terminals and changes the generated signal, as shown in figure (a).
To reduce this effect, a guard is furnished on the GS200’s source circuit and is connected
to the guard terminal, as shown in figure (b). If you connect the noise source to the guard
terminal, the noise current passes through the guard and is grounded, bypassing the
internal source circuit. In this way, you can reduce the amount of noise that enters the
circuit from the connected power source.
When the DUT is connected to the ground (it is directly connected to the noise source),
you can reduce the effect of common mode noise by turning the guard feature on. When
you do so, the connection becomes like the connection shown in figure (b). When the
DUT is not connected to the ground, as shown in figure (c), you can reduce the effect of
common mode noise by turning the guard feature off and directly connecting the DUT’s
ground (noise source) to the guard terminal.

Note
• If you change the range while a capacitive or inductive load such as a capacitor or coil is
connected, an abnormal load may be detected due to the energy build-up in the load, and
the output may turn off.
• In voltage source mode’s 10 mV and 100 mV ranges, because the GS200 uses a voltage
divider, the output resistance is approximately 2 Ω. Therefore, these ranges are not suitable
when the GS200 is connected to a load that allows current to flow (a low-impedance load).
Also, four-terminal connection does not function for these voltage ranges. You must use the
two-terminal connection instead. Connect a high-impedance load, a load that is sufficiently
larger than the output resistance.
• If the range is changed, a glitch will occur in the output for several µs to several hundred µs.
• When the range is changed, the fractional part of the source level that is outside of the
range determined by the new source range is discarded. However, if the source level is
outside of the range determined by the new source range, the source level is set to 0.
• The source range is fixed. The GS200 does not have an auto range feature.

Note
Because an output capacitance of approximately 500 pF exists between the GS200’s OUTPUT
Hi and OUTPUT Lo terminals:
• If the load changes drastically such as when a short circuit occurs in voltage source mode, a
large transient discharge current is generated from the output capacitance.
• If a voltage source (such as a power supply, amplifier, or signal generator) is connected as a
load, the load voltage source may be unstable due to the output capacitance.

• When the output relay operates, the source level changes as follows.
• When Output Is Turned On
The output relay turns on with the source level set to zero. After the output relay
switches, the source level is changed to the specified source level.
• When Output is Turned Off
The source level is set to zero, and then the output relay is turned off.
• When output is off, you cannot execute programs (see chapter 6) or perform measurements
(see chapter 7).
• At the 10 V and 30 V ranges, when you turn the output on, an internal process to reduce
the zero-point error takes place for 0.4 second. However, the internal process does not take
place in the following situations.
• If the output is turned on within 1 second after it is turned off.
• If output is turned on within 5 minutes after the power is turned on.

The Relationship between Capacitive and Inductive Loads and Output
• When a capacitive load is connected to the GS200 in voltage source mode, the
response time may become longer. Also, if the load has a capacitance of 10 µF or
greater, oscillation may occur.
• If you change the output settings drastically under the usage conditions listed above,
the limiter may be activated due to the inrush current.
• When an inductive load is connected to the GS200 in current source mode, the
response time may become longer. Also, if the load has an inductance of 1 mH or
greater, oscillation may occur.

Explanation
Integration Time
The stability of measured values increases as the integration time is set longer. However,
the measurement time will be longer. Set the integration time to an integer multiple of the
power line cycle (nPLC). The line frequency is measured automatically inside the GS200.
You can use the communication command “:SYSTem:LFRequency?” to check the
measured line frequency.
Range
1 PLC to 25 PLC (PLC stands for Power Line Cycles. One PLC is equivalent to one
period of the power source signal.)
Note
In one measurement operation, the output value and the zero reference value are both
measured. Therefore, the time for one measurement operation is: ((measurement delay
+ integration time) × 2) + software processing time (see section 2.5). For example, in an
environment where the power supply frequency is 50 Hz (1 PLC = 20 ms), if the measurement
delay is set to 0 ms and the integration time is set to 25 PLC (500 ms), the time required for
one measurement is the sum of approximately 1 second and the software processing time.
Software processing time is less than 1 ms.

Measurement (Option)
If zero calibration is executed, output is automatically turned off, the zero reference
is measured, and the zero reference is applied to subsequent measured results. The
zero point may change due to the passage of time, the GS200 being in an environment
where the temperature changes drastically, or due to other factors. By executing zero
calibration, the zero point is calibrated, and this enables the GS200 to generate more
accurate output measurement.

Explanation
To use the GS200’s network features, you must configure the TCP/IP settings.
DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol that temporarily allocates necessary information to a computer so
that it can connect to the Internet. If DHCP is turned on, the following settings will be
automatically assigned.
• IP address
• Subnet mask
• Default gateway
• To use DHCP, the network must have a DHCP server. Consult your network
administrator to see if DHCP is available.
• Different information may be assigned to the GS200 each time it is turned on. When
you are using a PC to access the GS200, you must check the GS200 IP address and
other network settings each time you turn the GS200 on.
11-4
IM GS210-01EN
11.3 Configuring Network Settings (TCP/IP)
1
IP Address (Internet Protocol Address)
• An IP address is a 32-bit value that is expressed using four octets. Each octet is
separated by a period and has a value from 0 to 255, as in “192.168.111.24.”
• Obtain an IP address from your network administrator.
• The IP address is automatically assigned in networks that use DHCP.
2
Subnet Mask
• Consult your network administrator for the subnet mask address. You may not need to
set the subnet mask.
• The subnet mask address is automatically assigned in networks that use DHCP.
Default Gateway
The default gateway setting is necessary to communicate between different subnets.
• Consult your network administrator for the default gateway address. You may not
need to set the default gateway.
• The default gateway address is automatically assigned in networks that use DHCP.
Transmission Terminator
You can set the terminator that is used to send data from the command control server at
port 7655.
• Select CR, LF, or CR+LF.
• The GS200 handles CR, LF, or CR+LF as the terminator when receiving data.
Note
• You must restart the GS200 to apply any changed network settings other than the
transmission terminator setting.
• You must also specify network settings, such as the IP address, on your PC. For information
on these settings, check your PC’s manual (help file) or consult your network administrator.

• IP address (see section 11.3)
• Subnet mask (see section 11.3)
• Default gateway (see section 11.3)
Note
If DHCP is enabled, “0.0.0.0” will be displayed for the IP address, subnet mask, and default
gateway until an address is assigned to the GS200. If the display does not change even after
30 seconds elapses after the GS200 is turned on, the DHCP address assignment may have
failed. If this happens, check that the Ethernet cable is connected correctly and that the LINK

12.4 7651-Compatible Mode
You can use the same communication commands with the GS200 that are available for
the YOKOGAWA 7651 Programmable DC Source. This is useful when you replace the
7651 with the GS200 or if you want to use both the GS200 and the 7651 in the same
system and control them using the same commands.
Note
You can only use the 7651-compatible mode with GP-IB communication. You cannot use it with
communication through other communication interfaces.
Setting the GP-IB Command Mode
Follow the procedure in section 12.3 to set the GP-IB command mode to 7651 mode.
Communication Commands That You Can Use in 7651 Mode
See the 7651 User’s Manual, IM7651-01E.
However, there are the following limitations.
• The following commands are not supported.
• IC memory card initialization (CI)
• Calibration feature commands (YZPm, YZSm, YZW, YZE, and YZO)
• RS-232-C-specific commands (<ESC>R, <ESC>L, <ESC>S, and <ESC>C)
• In the return value of the status output command (OC):
• The CAL switch bit and the normal/calibration mode bit are always 0.
• The IC memory card bit is always 1.
• If parameters are not included for communication commands that require parameters,
a communication error occurs.
The 7651-Mode Status Byte
In 7651 mode, the status byte is also 7651-compatible. For details, see the 7651 User’s
Manual, IM7651-01E.

12.5 Responses to Interface Messages
What Are Interface Messages?
Interface messages are also referred to as interface commands or bus commands. They
are commands that are issued by the controller. They are classified as follows:
Uni-line Messages
2
3
A single control line is used to transmit uni-line messages. The following three types of
messages are available.
IFC (Interface Clear), REN (Remote Enable), and IDY (Identify)
4
Multi-line Messages
5
Eight data lines are used to transmit multi-line messages. The messages are classified
as follows:
• Address Commands
These commands are valid when the instrument is designated as a listener or as a
talker. The following five commands are available.
• Commands that are valid on an instrument that is designated as a listener
GTL (Go To Local), SDC (Selected Device Clear), PPC (Parallel Poll Configure),
and GET (Group Execute Trigger)
• A command that is valid on an instrument that is designated as a talker
TCT (Take Control)
• Universal Commands
These commands are valid on all instruments regardless of their listener or talker
designation. The following five commands are available.
LLO (Local Lockout), DCL (Device Clear), PPU (Parallel Poll Unconfigure), SPE (Serial
Poll Enable), and SPD (Serial Poll Disable)
Other Interface Messages
6
7
8
9
10
11
Listener address, talker address, and secondary commands are also considered
interface messages.
Difference between SDC and DCL
12
GP-IB Interface
In multi-line messages, SDC messages are those that require talker or listener
designation and DCL messages are those that do not require a designation. Therefore,
SDC messages are directed at a particular instrument while DCL messages are directed
at all instruments on the bus.

Messages
Messages are used to exchange information between
the controller and the GS200. Messages that are sent
from the controller to the GS200 are called program
messages, and messages that are sent from the
GS200 back to the controller are called response
messages.
If a program message contains a message unit that
requests a response (a query), the GS200 returns
a response message upon receiving the program
message. The GS200 returns a single response
message in response to a single program message.

Response Message Unit Syntax
Attach program data if there are conditions that are
required to execute a command. Separate the program
data from the header with a space (ASCII code 20H). If
there are multiple sets of program data, separate each
set with a comma.
For details, see page 13-5.
Example
:SOURce:FUNCtion VOLTage<PMT>
Header
Data
RMT is a response message terminator. It is NL^END.
The response message unit syntax is shown below.
,
<Response data>
<Response Header>
A response header sometimes precedes the response
data. Separate the data from the header with a space.
For details, see page 13-5.
<Response Data>
Response data contains the content of the response. If
there are multiple sets of response data, separate each
set with a comma.
Example
50.0E-3<RMT>
1,256<RMT>
VOLT<RMT>
If there are multiple queries in a program message,
responses are returned in the same order that the
queries were received in. In most cases, a single query
returns a single response message unit, but there
are a few queries that return multiple units. The first
response message unit always corresponds to the first
query, but the nth response unit may not necessarily
correspond to the nth query. Therefore, if you want to
make sure that every response is retrieved, divide the
program messages into individual messages.

13.1 Program Format
Precautions to Be Taken when Sending
and Receiving Messages
• If the controller sends a program message that does
not contain a query, the controller can send the next
program message at any time.
• If the controller sends a program message that
contains a query, the controller must finish receiving
the response message before it can send the next
program message. If the controller sends the next
program message before receiving the response
message in its entirety, an error will occur. A
response message that is not received in its entirety
will be discarded.
• If the controller tries to receive a response message
when there is none, an error will occur. If the
controller tries to receive a response message
before the transmission of the program message is
complete, an error will occur.
• If the controller sends a message that contains
multiple message units, and the message contains
an incomplete unit, any program units that follow the
incomplete one will not be processed.
Commands
There are three types of commands (program
headers) that a controller may send to the GS200. The
commands differ in their program header formats.
Common Command Header
Commands that are defined in IEEE 488.2-1987 are
called common commands. The common command
header syntax is shown below. Be sure to include an
asterisk (*) at the beginning of a common command.
*
<Mnemonic>
2

5
?
Example *CLS
6
Compound Header
Commands, other than common commands, that are
specific to the GS200 are classified and arranged in a
hierarchy according to their functions. The compound
header syntax is shown below. Be sure to use a colon
to specify a lower hierarchical level.
Deadlock
The GS200 can store at least 64 KB of messages in its
transmit and receive buffers (the number of available
bytes varies depending on the operating conditions).
If both the transmit and receive buffers become full
at the same time, the GS200 will no longer be able
to operate. This condition is called a deadlock. If this
happens, you can resume operation by discarding
response messages.
Deadlock will not occur if the program message
(including the <PMT>) is kept below 64 KB. Program
messages that do not contain queries never cause
deadlocks.

13.1 Program Format
When Concatenating Commands
Command Groups
A command group is a group of commands that have
common compound headers arranged in a hierarchy. A
command group may contain sub-groups.
ExampleGroup of commands related to source
:SOURce:FUNCtion
:SOURce:RANGe
:SOURce:LEVel:FIX
:SOURce:LEVel:AUTO
:SOURce:PROTection:VOLTage
:SOURce:PROTection:CURRent
When Concatenating Commands of the Same
Group
The GS200 stores the hierarchical level of the
command that is currently being executed and
processes the next command on the assumption that
it belongs to the same level. Therefore, the common
header section can be omitted for commands that
belong to the same group.
Example
:SOURce:FUNCtion VOLTage;
RANGe 100E-3<PMT>
When Concatenating Commands of Different
Groups
If the subsequent command does not belong to the
same group, place a colon in front of its header.
Example
:SOURce:FUNCtion VOLTage;:SENSe:
TRIGger READy<PMT>
When Separating Commands with <PMT>
If you separate two commands with a terminator,
two program messages will be sent. Therefore, the
common header must be specified for each command
even when commands belonging to the same
command group are being concatenated.
Example
:SOURce:FUNCtion VOLTage<PMT>:SOURce:
FUNCtio RANGe 100E-3<PMT>
Header Interpretation Rules
The GS200 interprets the header that it receives
according to the rules below.
• Mnemonics are not case sensitive.
SOURce can also be written as
Example
source or Source.
• The lower-case characters of mnemonics can be
omitted.
SOURce can also be written as
Example
SOURc or SOUR.
• The question mark at the end of a header indicates
that it is a query. You cannot omit the question mark.
ExampleThe shortest abbreviation for
OUTPut? is OUTP?.
• If the <x> (value) at the end of a mnemonic is
omitted, it is interpreted as a 1.
ExampleIf FILT is specified for FILTer<x>,
it means FILTer1.
• Parts of commands and parameters enclosed in
square brackets ([ ]) can be omitted.
OUTPut[:STATe] 1
Example
can be written as OUTPut 1.
When Concatenating Simple Headers
If a simple header follows another command, place a
colon in front of the simple header.
Example
:SOURce:FUNCtion VOLTage;:INITiate<PMT>
When Concatenating Common Commands
Common commands that are defined in IEEE 488.21992 are independent of hierarchy. A colon is not
needed before a common command.
Example
:SOURce:FUNCtion VOLTage;*CLS<PMT>

When the controller sends a message unit that has
a question mark in its program header (a query), the
GS200 returns a response message to the query.

Data contains conditions and values that are written
after the header. A space separates the data from the
header. Data is classified as follows:

<Block Data>
<Block data> is any 8-bit data. It is only used in
response messages on the GS200. The syntax is as
follows:
Syntax Example
#N<N-digit decimal number><data byte sequence>
#800000010ABCDEFGHIJ
•#N
Indicates that the data is <block data>. “N” indicates
the number of succeeding data bytes (digits) in
ASCII code.
• <N-digit decimal number>
Indicates the number of bytes of data (example:
00000010 = 10 bytes).
• <Data byte sequence>
Expresses the actual data (example: ABCDEFGHIJ).
• Data is comprised of 8-bit values (0 to 255). This
means that the ASCII code “0AH,” which stands for
“NL,” can also be included in the data. Hence, care
must be taken when programming the controller.

This bit is set to 1 when the output queue is not empty.
For details, see page 13-31.

This bit is set to 1 when the logical AND of the standard
event register and the standard event enable register
is 1. For details, see page 13-29.
Bit 6RQS (Request Service)/MSS (Master
Status Summary)
This bit is set to 1 when the logical AND of the status
byte excluding bit 6 and the service request enable
register is 1. RQS is set to 1 when the MSS bit
changes from 0 to 1 and is cleared when serial polling
is carried out or when the MSS bit changes to 0.
Bit Masking
To mask a bit in the status byte so that it does not
cause an SRQ, set the corresponding bit of the service
request enable register to 0.
For example, to mask bit 2 (EAV) so that service is not
requested when an error occurs, set bit 2 of the service
request enable register to 0. Do this using the *SRE
command. To query whether each bit of the service
request enable register is 1 or 0, use *SRE?. For
details on the *SRE command, see section 13.2.11.
13-28
Status Byte Operation
A service request is issued when bit 6 in the status
byte becomes 1. Bit 6 is set to 1 when any other bit
becomes 1 (when the corresponding bit of the service
request enable register is also set to 1).
For example, if an event occurs and the logical OR
of a standard event register bit and its corresponding
enable register bit is 1, then bit 5 (ESB) is set to 1. At
this point, if bit 5 of the service request enable register
is 1, bit 6 (MSS) is set to 1, and the GS200 requests
service from the controller.
You can check what type of event occurred by reading
the contents of the status byte.
Reading the Status Byte
There are two ways to read the contents of the status
byte.
*STB? Query
Bit 6 functions as MSS when a query is made using
*STB?. This causes the MSS to be read. This query
does not cause any of the status byte bits to be cleared
after the status byte is read.
Serial Polling
Serial polling causes bit 6 to function as an RQS bit.
This causes the RQS to be read. After the status byte
is read, only the RQS bit is cleared. You cannot read
the MSS bit when serial polling is used.
Clearing the Status Byte
There is no way to clear all the bits in the status byte.
The bits that are cleared for each operation are shown
below.
*STB? Query
None of the bits are cleared.
Serial Polling
Only the RQS bit is cleared.
When a *CLS command is received
When a *CLS command is received, the status byte
itself is not cleared, but the contents of the standard
event register, which affects the bits in the status byte,
are cleared. As a result, the corresponding status
byte bits are cleared. Because the output queue is
not cleared with a *CLS command, bit 4 (MAV) in the
status byte is not affected. However, the output queue
will also be cleared if the *CLS command is received
just after a program message terminator.

Bit 5
CME (Command Error)
This bit is set to 1 when there is a command syntax
error.
Bit 7
PON (Power On)
This bit is set to 1 when the GS200 turns on.
Standard Event Register Operation
The standard event register indicates six types of
events that occur inside the GS200. When one of the
bits in this register is 1 (and the corresponding bit of
the standard event enable register is also 1), bit 5 (ESB)
in the status byte is set to 1.
Example
1. A query error occurs.
2. Bit 2 (QYE) is set to 1.
3. When bit 2 of the standard event enable register
is 1, bit 5 (ESB) in the status byte is set to 1.
You can also check what type of event occurred in the
GS200 by reading the contents of the standard event
register.
Reading the Standard Event Register
You can use the *ESR? command to read the contents
of the standard event register. The register is cleared
after it is read.
Clearing the Standard Event Register
The standard event register is cleared in the following
three cases.
• When the contents of the standard event register
are read using the *ESR command.
• When a *CLS command is received
• When the GS200 is restarted.

Bit Masking
To mask a certain bit of the standard event register so
that it does not cause bit 5 (ESB) in the status byte to
change, set the corresponding bit of the standard event
enable register to 0.
For example, to mask bit 2 (QYE) so that ESB will not
be set to 1 even if a query error occurs, set bit 2 of
the standard event enable register to 0. Do this using
the *ESE command. To query whether each bit of the
standard event enable register is 1 or 0, use *ESE?.
For details on the *ESE command, see section 13.2.11.

The extended event register bit is set to 1 when the
GS200 output trips.
The condition register bit is set to 1 when an abnormal
temperature has been detected and the GS200 needs

To mask a certain bit of the extended event register
so that it does not cause bit 1 (ESS) in the status
byte to change, set the corresponding bit of the
extended event enable register to 0. Do this using the
:STATus:ENABle command.
Extended Event Register and Condition
Register Operation
The extended event register indicates thirteen types of
events that occur inside the GS200. When one of the
bits in this register is 1 (and the corresponding bit of
the extended event enable register is also 1), bit 1 (EES)
in the status byte is set to 1.
Example
1. A program completes execution.
2. Bit 7 (EOP) is set to 1.
3.When bit 7 of the extended event enable register
is 1, bit 1 (EES) in the status byte is set to 1.
You can also check what type of event occurred in the
GS200 by reading the contents of the extended event
register.
The condition register indicates nine types of events
that occur inside the GS200. You can check the
internal condition of the GS200 by reading the contents
of the condition register.
IM GS210-01EN
13.3 Status Reports
Reading the Extended Event Register and
Condition Register
You can use the :STATus:EVENt? command to read
the contents of the extended event register. The
register is cleared after it is read. You can use the
:STATus:CONDition? command to read the contents
of the condition register. The register does not change
even if it is read.
Clearing the Extended Event Register
The extended event register is cleared in the following
three cases.
• When the contents of the extended event register
are read using the :STATus:EVENt? command.
• When a *CLS command is received
• When the GS200 is restarted.
13.3.5 Output Queue and Error
Queue

Output Queue
2
The output queue stores query response messages.
As shown below, data is stored in order and read from
the oldest message first. The output queue is cleared
in the following cases.
• When a new message is received from the
controller.
• When a deadlock occurs (see page 13-3).
• When a device clear command (DCL or SDC) is
received.
• When the GS200 is restarted.
The *CLS command does not clear the output queue.
You can determine whether or not the output queue is
empty by checking bit 4 (MAV) in the status byte.

Communication Commands
When an error occurs, the error queue stores the
error number and message. For example, if the
GS200 receives an incorrect program message from
the controller, the error number (–113) and the error
message (“Undefined header”) are stored in the error
queue when the GS200 displays the error message.
You can use the :SYSTem:ERRor? query to read the
contents of the error queue. Like the output queue, the
messages in the error queue are read from the oldest
one first.
If the error queue overflows, the last message is
replaced with the following message: –350, “Queue
overflow.”
The error queue is cleared in the following cases.
• When a *CLS command is received.
• When the GS200 is restarted.
You can determine whether or not the error queue is
empty by checking bit 2 (EAV) in the status byte.

or for Measurement Categories II, III, and IV.
Measurement category Other (O) applies to measurement of circuits that are not directly connected to a main power supply.
This category applies to measurement of secondary electric circuits in equipment across a transformer. The estimated
transient overvoltage that may be applied to the GS200 signal input terminals is 1500 V.
Measurement category II applies to measurement of circuits, such as household electric appliances and portable electric tools,
that are connected to low-voltage installations.
Measurement category III applies to measurement of facility circuits, such as distribution boards and circuit breakers.
Measurement category IV applies to measurement of power source circuits, such as entrance cables to buildings and cable
systems, for low-voltage installations.
3 The overvoltage category (installation category) is a value used to define the transient overvoltage condition and includes the
rated impulse withstand voltage. The overvoltage category II applies to electrical equipment that is powered through a fixed
installation, such as a switchboard.
4 Pollution Degree applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand voltage or surface
resistivity. Pollution Degree 2 applies to normal indoor atmospheres (with only non-conductive pollution).

The GS200 consists of a digital section that operates at ground potential and an
analog section that is isolated from the digital section. The digital section consists of a
CPU, FPGA, memory, and various interface circuits. A non-isolated DC-DC converter
supplies power to the digital section. The digital section controls the display, keys,
communications, and the analog section.
The analog section consists of the voltage source’s D/A converters (DACs), an output
amplifier, highly stable shunt resistors, and a limiter circuit. An isolated commercial
transformer provides power to the analog section.
Data that is sent from the digital section passes through a photocoupler and the PLD and
controls each DAC and the various switches that are used for making range settings and
other settings.
When the GS200 is operating as a voltage source, SW1 is connected to V, and source
voltage Vo is the product of source DAC value Vs and R2/R1. If load current IL increases
positively and IL × Rs exceeds positive limiter DAC value Vp, the diode of the limiter
circuit will turn on and suppress the load current to Vp/Rs. A similar operation takes place
when the load current is negative.
When the GS200 is operating as a current source, SW1 is connected to I, and source
current Io is the product of source DAC value Vs and (R2/R1)/Rs. If load voltage VL
exceeds positive limiter DAC value Vp, the diode of the limiter circuit will turn on and
suppress the load voltage to Vp. A similar operation takes place when the load voltage is
negative.
The GS200 is equipped with a measurement circuit that is separate from the source and
limiter circuits. In voltage source mode, the measurement circuit uses A/D converters
(ADC) to measure the current that is received. In current source mode, the measurement
circuit uses A/D converters (ADC) to measure the voltage that is received. Differing
from the voltage and current source functions described above, when the mV range is
selected in voltage source mode, SW2 is connected to mV. The source voltage Vo is
voltage-divided by R3 and R4. In this situation, because the output resistance becomes
R4 (2 Ω), if the DUT does not have a high impedance, the source voltage is reduced
according to the DUT’s impedance. Additionally, because selecting mV causes the limiter
and current measurement circuits to be disconnected by Rs and SW2 that are used for
current sense, these circuits do not operate.
