Safety Precautions

This instrument is an IEC safety class I instrument (provided with a terminal for protective earth grounding). The general safety precautions described herein must be observed during all phases of operation. If the instrument is used in a manner not specified in this manual, the protection provided by the instrument may be impaired. Yokogawa Electric Corporation assumes no liability for the customer’s failure to comply with these requirements.

The following symbols are used on this instrument.

Warning: handle with care. Refer to the user’s manual or service manual.

This symbol appears on dangerous locations on the instrument which require special instructions for proper handling or use. The same symbol appears in the corresponding place in the manual to identify those instructions.

Ground (earth) or functional ground terminal (do not use this terminal as a

protective ground terminal).

Alternating current

ON (power)

OFF (power)

In-position of a bi-stable push control

Out-position of a bi-stable push control

Be sure to comply with the precautions below. Not complying might result in injury or death.

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.

IM GS210-01EN

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.

Safety Precautions

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 Operate with Defective Protective Grounding or Fuse

Do not operate the instrument if the protective earth or fuse might be defective. Also, make sure to check them before operation.

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. If you are going to touch the circuit, make sure to turn OFF the circuit and check that no voltage is present.

Measurement Category

The measurement category of the GS200 signal input terminals is Other (O). Do not use it to measure the main power supply or for Measurement Categories II, III, and IV.

Limits

When the source function is set to voltage, this displays the current limit. When the source function is set to current, this displays the voltage limit. When the source range is set to 10 mV or 100 mV, the limit is fixed to 200 mA (you cannot change this value). In these situations, “------mA” is displayed for the limit.

Note

In voltage source mode’s 10 mV and 100 mV ranges, the output resistance is approximately 2

. Therefore, these ranges are not suitable when the GS200 is connected to a load that allows

current to flow (a low-impedance load). Connect a load that allows as little current to flow as possible (a high-impedance load).

Product Features and System Configuration

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

current sink in the range of ±32 V and ±200 mA.

• The GS200 has an optional voltage and current measurement 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 ste controls the generation of voltage or current. You can also generate ramp waveforms by using the slope setting.

• Y

ou 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) o 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 (GS2 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 us

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-1

1 protocol/7655 command socket).

ou can also use the Ethernet interface to access the GS200’ 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).

This section explains the basic features of the GS200: the source feature and the measurement feature (monitoring feature).

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.

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.

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.

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.

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.

oltage ranges:

1 V, 10 V, and 30 V

Maximum output current: ±200 mA (at 1 V, 10 V, and 30 V ranges)

Current ranges: 1 mA, 10 mA, 100 mA, and 200 mA Maximum output voltage: ±30 V

Voltage and Current Generation Region

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.

The monitoring feature can be used to:

• Check that current is flowing.

• Check and inspect current consumption.

• Log fluctuations in the load current.

• Record V-I characteristics.

Voltage Source Range (See section 5.2 for the procedure)

The following voltage source ranges are available.

* 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 following current source ranges are available.

Features

Source Function (See section 5.1 for the procedure)

Source Action

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.

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.

IM GS210-01EN

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.

The output is connected, and the specified source level is generated. In this

ON:

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.

Voltage Limiter and Current Limiter

If a limiter is set, an additional limit can be placed within the source range. This limit can prevent damage to the connected device due to overcurrent or overvoltage. In voltage source mode, the current limiter is enabled. In current source mode, the voltage limiter is enabled.

Features

Limiter Operation in Current Source Mode

A limiter has an operating range which is defined by a positive value and a negative value in relation to 0. The positive value is the high limit. The negative value is the low limit. If the high limiter is activated, the high limiter indicator (H) is displayed. If the low limiter is activated, the low limiter indicator (L) is displayed.

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)

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.

IM GS210-01EN

Guard Terminal Feature (See section 4.3 for the procedure)

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.

Next step’s source level – current step’s source level

Program Feature (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.

Programs can contain up to 10000 steps. If the number of steps exceeds 10000, only the first 10000 steps are loaded.

Program Interval Time (See section 6.2 for the procedure)

The program interval time specifies the execution interval for each step in the program.

Features

Program Slope Time (See section 6.3 for the procedure)

The program slope time specifies the amount of time that the GS200 takes to linearly change (increase or decrease) the current step’s source level to the next step’s source level from the beginning of the step. The slope of this linear line is calculated as follows:

When Ts is greater than Ti, the situation shown in the bottom right section of the figure above occurs, so be sure to make Ts less than or equal to Ti.

Repeating Programs (See section 6.1 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.

Program Triggers (See section 6.4 for the procedure)

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 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.

2.4 Programs

You can use the USB storage feature (see page 2-22) to store programs in the PROGRAM folder in the GS200’s non-volatile disk (GS200ROM). Prgm01.csv and Prgm02.csv that are stored in the PROGRAM folder when the GS200 is sent from the factory or when you format its disk are program file samples. You can check the contents of program files on the display.

Program File Contents (See section 6.5 for the procedure)

Program files are text files that have been created and edited in spreadsheet applications or text editors. Each file contains multiple lines, and each line represents one step in the program.

Features

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.

Executing Programs (See section 6.7 for the procedure)

Operations When the Program Trigger Is Set to Norm

You can use the RUN, STEP, and HOLD keys and external triggers to control the program execution. The program interval time specifies the execution interval for each step in the program.

When you press the HOLD or STEP key, the trigger busy (TrigBusy) and source change completion (Ready) signals change as shown in the following example.

Program Setup Example Step 1: 1 V Step 2: 2 V Step 3: 3 V

Program Conditions

•

Repeat mode is of

• Program interval time is 5 s.

• Program slope time is 3 s.

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 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.

Operations When the Program Trigger Is Set to M.End (/MON option)

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 ON (On)

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.

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.

Measurement Delay (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 2-9). 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.

Features

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 value. When you turn NULL computation on, the next measured value is taken to be the NULL value. For subsequent measured values, the measured results are obtained by subtracting this NULL value.

Measured result = measured value – NULL

Store/Recall (Statistical Computation Value Display)

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

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.

2.6 Triggering

2-20

IM GS210-01EN

Overview

The GS200 uses program triggers, which are used to start and pause programs, and measurement triggers, which are used to start measurements.

Program Triggers (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 Press this key to execute only the current step. When the program interval time

• HOLD key Press this key to pause the program that is running. If you pre

elapses, program execution stops.

ss this key when a program is paused, program execution begins again from the exact point in the step that it was previously paused.

inal 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

Measurement Triggers (/MON option; see section 7.4 for the procedure)

This trigger is used to start a measurement operation (see section 2.5). Select any of the following trigger sources.

• Measurement timer ( can set the constant period timer to a period from 0.1 seconds to 3600.0 seconds.

2.7 Synchronization

2-24

IM GS210-01EN

Synchronization

You can connect multiple GS200s and synchronize switching of the output between on and off and their program execution.

External I/O

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.

2.8 Other Features

USB Storage Feature (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.

Features

Non-Volatile Disk (GS200ROM)

The GS200ROM is a non-volatile disk. Even if you turn the GS200 off, the contents of this disk are not lost. Two folders are stored on this disk: PROGRAM and SETUP.

IM GS210-01EN

2-25

2.8 Other Features

2-26

IM GS210-01EN

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.

2.8 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.

Command Control Using VXI-11

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.

Features

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.

3.1 Handling Precautions

Read the Safety Precautions

Safety Precautions

If you are using the GS200 for the first time, make sure to read “Safety Precautions,” on pages v and vi.

Do Not Remove the Case

Do not remove the case from the instrument. Some sections inside the instrument have high voltages that are extremely dangerous. For internal inspection and adjustment, contact your nearest YOKOGAWA dealer.

Unplug If Abnormal Behavior Occurs

If you notice smoke or unusual odors coming from the instrument, immediately turn off the power and unplug the power cord. If these symptoms occur, contact your nearest YOKOGAWA dealer.

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.

Instrument Preparation and Common Operations

Turn the Power Switch Off If Overheat is Detected

If the GS200 detects an overheat condition such as when the inlet or vent holes for the cooling fan are obstructed or the fan is stopped, the GS200 forcibly turns the output off, displays an “Abnormal Temperature” warning, and produces intermittent beeps. If this happens, immediately turn the power switch off. Check that there is adequate space around the GS200, and check for and remove any foreign objects that are caught in the cooling fan on the rear panel. If the same warning appears when you turn the power switch on after waiting a sufficient amount of time, the GS200 may be malfunctioning. Contact your nearest YOKOGAWA dealer.

Handle the Power Cord with Care

Nothing should be placed on top of the power cord. The power cord should also be kept away from any heat sources. When unplugging the power cord from the outlet, never pull by the cord itself. Be sure to hold and pull by the plug. If the power cord is damaged, purchase a replacement with the same part number as the one indicated on page iii.

3.4 Turning the Power Switch On and Off

Off On

Before Turning On the Power, Check That:

• The instrument is installed properly (see section 3.2, “Installation”).

• The power cord is connected properly (see section 3.3, “Connecting the Power Supply”).

Location of the Power Switch and On/Off Operation

The power switch is located in the lower left of the front panel. The power switch is a push button. Press the button once to turn the instrument on, and press it again to turn the instrument off.

Operations Performed When the Power Is Turned On

When the power switch is turned on, the GS200 logo appears on the screen, and a selftest starts automatically. If the test completes successfully, the GS200 is configured according to the setup file selected in section 9.3, “Selecting the Settings Applied at Power-On.” Check that the GS200 has started normally before you use it.

Instrument Preparation and Common Operations

Note

• Wait at least 5 seconds after you turn the GS200 off before you turn it back on.

When the Power-on Operation Does Not Finish Normally

Turn off the power switch, and check the following items.

• The power cord is securely connected.

• The voltage supplied from the power outlet is correct (see section 3.3).

• You can initialize the settings of the GS210 (see section 9.1).

If, after checking these items, the GS200 still fails to start when you turn the power switch on, it may be malfunctioning. Contact your nearest YOKOGAWA dealer for repairs.

To Generate Accurate Output and Make Accurate Measurements

With the GS200 installed in a location that complies with the guidelines given in section 3.2, allow the instrument to warm up for at least 60 minutes after the power switch is turned on. Turn the output off during warm-up. After the warm-up time elapses, turn the output on.

Operations Performed When the Power Is Turned Off

The setup data and measured results immediately before the power switch is turned off are not retained. The same is true when the power cord is disconnected from the outlet. We recommend that you save important setup data to the SETUP folder on the nonvolatile disk (GS200ROM). See sections 2.8, “USB Storage Feature” and 9.2.

Note

• If you turn the power off while output is on, the GS200 may produce a momentary beeping sound, but this sound does not indicate an error.

Common Settings

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 GS200 is connected to a load that allows current to flow (a low-impedance load).

IM GS210-01EN

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 GS200 is connected to the DUT (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 GS200 is not connected to the DUT, 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.

• 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 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.

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.

5.5 Turning the Output On and Off

Procedure

Press OUTPUT. The OUTPUT key illuminates while the output is on. If you press OUTPUT while the output is on, the output will stop. When the output stops, the OUTPUT key turns off.

Explanation

Turning the Output On and Off

The output relay switches between on and off.

Note

• 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 c

the limiter may be activated due to the inrush current.

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.

Storage Count

The storage count specifies the number of measured results that are stored. Range: 1 to 10000

Turning the Result File (Result.csv) Generation Feature On and Off

If you turn the result file generation feature on, when the storage operation finishes, the GS200 stores a result file that contains a list of all the contents of storage memory. The result file (Result.csv) is a text file in CSV format. It is stored on the GS200RAM disk. If the number of measurements that are performed exceeds the storage count, this file only contains results from as many measurements as the storage count specifies.

Note

• GS200RAM is a volatile-memory disk. The files that are stored on it are lost when you turn off the GS200. If there are result files that you want to retain, move them to the connected PC before you turn off the GS200.

• If the measured value is greater than the positive limit of the measurement range, “+INF” is written to the measured value section of the result file. If the measured value is lower than the negative limit of the measurement range, “–INF” is written to the measured value section of the result file.

8.1 Synchronous Operation Using the BNC I/O Terminals (IN and OUT)

Using the BNC Terminals to Perform Synchronous Operation with Multiple GS200s

You can synchronize the output (turning on and off) and program execution of multiple GS200s by connecting their OUTPUT OUT and OUTPUT IN or TRIG OUT and TRIG IN signals.

Example of Synchronizing Program Execution

Note

• The maximum delay from TRIG IN to TRIG OUT is less than or equal to 1 μs.

• The maximum delay from OUTPUT IN to OUTPUT OUT is less than or equal to 20 ms.

• If you are using both the RJ-11 connectors and BNC terminals, do not apply the same signal to them at the same time. Doing so may cause errors.

Using the BNC Terminals to Perform Synchronous Operation with the GS200 and Other Devices

You can control the GS200’s output (turning on and off) and program execution by applying OUTPUT IN or TRIG IN signals that are transmitted from a device such as a controller. Additionally, if you connect the GS200’s READY OUT signal to the measurement trigger input of an external DMM, you can start measurements when the output source stabilizes.
