Safety Precautions

The following safety precautions should be observed before using this product an d any associated instrumentation. Although some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous conditions may be present.

This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the user documentation for complete product specifications.

If the product is used in a manner not specified, the protection provided by the product warranty may be impaired. The types of product users are: Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is

operated within its specifications and operating limits, and for ensuring that operators are adequately trained. Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the instrument.

They must be protected from electric shock and contact with hazardous live circuits. Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line voltage or

replacing consumable materials. Maintenance procedures are described in the user documentation. The procedures explicitly state if the operator may perform them. Otherwise, they should be performed only by service personnel.

Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained service personnel may perform installation and service procedures.

Keithley Instruments products are designed for use with electrical signals that are rate d Measurement Category I and Measurement Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages. Measurement Category II connections require protection for high transient over-voltages often associated with local AC mains connections. Assume all measurement, control, and data I/O connections are for connection to Category I sources unless otherwise marked or described in the user documentation.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS, 42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock. If the circuit is capable of operating at or above 1000V, no conductive part of the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance-limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit f and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.

ault current

06/07

When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power

disconnect device must be provided in close proximity to the equipment and within easy reach of the operator. For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under test.

AL W AYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.

The instrument and accessories must be used in accordance with its specifications and operating instructions, or the safety of the equipment may be impaired.

Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information, and as shown on the instrument or test fixture panels, or switching card.

When fuses are used in a product, replace with the same type and rating for continued protection against fire hazard. Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections. If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use of a lid

interlock. If a screw is present, connect it to safety earth ground using the wire recommended in the user documentation. The symbol on an instrument indicates that the user should refer to the operating instructions located in the user documentaion. The symbol on an instrument shows that it can source or measure 1000V or more, including the combined effect of normal and

common mode voltages. Use standard safety precautions to avoid personal contact with these voltages. The symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns. The symbol indicates a connection terminal to the equipment frame.

If this symbol is on a product , it indicates that mercur y is present in the display lamp. Please note that the lamp must be properly disposed of according to federal, state, and local laws.

The WARNING heading in the user documentation explains dangers that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the user documentation explains hazards that could damage the instrument. Such damage may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans. Before performing any maintenance, disconnect the line cord and all test cables. T o maintain protection from electric shock and fire, replacement components in mains circuits - including the power transformer, test leads,

and input jacks - must be purchased from Keithley Instruments. Standard fuses with applicable national safety approvals may be used if the rating and type are the same. Other components that are not safety-related may be purchased from other suppliers as long as they are equivalent to the original component (note that selected parts should be purchased only through Keithley Instruments to maintain accuracy and functionality of the product). If you are unsure about the applicability of a replacement component, call a Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water-based cleaner. Clean the exterior of the instrument only. Do not apply cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for proper cleaning/servicing.

Switching module installation and connections

In order to exercise close/open operations explained in this section, a switching module (or pseudocard) must be installed in the mainframe. A switching module can be installed by the user, however external connections to the switching module are only to be performed by qualified service personnel.

WARNING To prevent electric shock that could result in injury or death, NEVER

handle a switching module that has power applied to it:

• Before installing (or removing) a switching module, make sure the Series

3700 is turned off and disconnected from line power.

• If the switching module is already connected to a device under test (DUT), make sure power is removed from all external circuitry.

NOTE For inexperienced users, it is recommended that DUT and external circuitry not be

connected to switching modules. This will allow you to exercise safe close/open operations without the dangers associated with live test circuits.

Module installation

WARNING Slot covers must be installed on unused slots to prevent personal contact

Perform the following steps to install a switching module into the Series 3700 mainframe:

1. Turn the Series 3700 off and disconnect the power line cord and any other cables connected to the rear panel.

2. Position the Series 3700 so that you are facing the rear panel.

3. Remove the slot cover plate from the desired mainframe slot. Retain the plate and screws for future use.

4. With the top cover of the switching module facing up, align the module's card edge into the slot's card guide and slide in the module. For the last ¼ inch or so, press in firmly to mate the module connector to the mainframe connector.

5. On each side of the module, there is a mounting screw. Tighten these two screws to secure the module to the mainframe. Do not overtighten.

6. Reconnect the power line cable and any other cables to the rear panel.

any installed switching module.

switching module terminals are connected at the same time, the test lead insulation must be rated to the highest voltage that is connected. For example, if 300V is connected to the analog backplane connector, the test lead insulation for the switching module must also be rated for 300V.

Dangerous arcs of an explosive nature in a high energy circuit can cause

severe personal injury or death. If the multimeter is connected to a high energy circuit when set to a current range, low resistance range, or any other low impedance range, the circuit is virtually shorted.

Dangerous arcing can result (even when the multimeter is set to a voltage

range) if the minimum voltage spacing is reduced in the external connections. For details about how to safely make high energy measurements, see High-energy circuit safety precautions.

As described in the International Electrotechnical Commission (IEC)

Standard IEC 664, the Series 3700 is Installation Category I and must not be connected to mains.

Pseudocards

You can perform open/close/scan operations and configure your system without having an actual switching module installed in your Series 3700. Using remote programming, you can assign a pseudocard to an empty switching module slot, allowing the Model 3700S to operate as if a switching module were installed.

A pseudocard, which is essentially a "virtual switching module," cannot be installed from the front panel. However, once the remote installation is complete, you can take the Series 3700 out of remote mode and use the front panel. Pressing the LOCAL or EXIT key takes the Series 3700 out of remote mode.

When the instrument is turned off, the pseudocard will be lost (uninstalled). In order to recall a pseudocard, make it part of a saved setup.

NOTE A saved setup retains the model number of the module installed in each slot. The

model number of a pseudocard is the same as the model number of an actual module. This allows a saved setup to be recalled provided the installed card (or pseudocard) matches the model number for the slot in the saved setup.

Pseudocards programming example

Use the following command line to set the pseudocard of Slot 6 for 3720 Dual 1 x 30 Multiplexer card simulation:

Channel assignments

Each switching module has a certain number of channels. For example, the Model 3720 switching module has 60 channels (1 through 60). When you encounter a 1 to 3-digit channel number in this manual, the switching module channel is the point of discussion. A four-digit channel number includes the slot followed by the 3-digit channel number.

A switching module can be installed in any of the mainframe's six slots. Therefore, to close, open, or scan a channel, it is necessary to specify the slot location and channel number of the switching module. This is accomplished by using a four-digit channel number for the mainframe. The first digit (1, 2, 3, 4, 5, or 6) indicates the slot number, and the next three digits indicate one of the following:

 The channel number of a switching module (see "Mux (multiplexer) channel notation" on

page 4-5)

 The row and column of a matrix card (see "Matrix card notation" on page 4-5)

slot[6].pseudocard = slot.PSEUDO_3720

 The modules' backplane relay (see "Backplane relay notation" on page 4-4)

Bus operation

The Series 3700 supports bus operation over USB, Ethernet and GPIB. The GPIB settings may be set from the front panel, or once controlled by the bus, over the bus.

1. Viewing or configuration using the front panel:

2. Viewing or configuration over the bus:

USB is always connected and available to send bus commands. There are no unique USB settings. To use USB, make sure have installed the Test Script Builder application. The applicable USB driver is available after installing this software.

NOTE For your Series 3700 to be recognized by your computer over the USB interface, the

a) Press MENU key to bring up the main menu, b) Turn the wheel to scroll to "GPIB" menu item and press the ENTER key. c) Select setting to change ADDRESS or ENABLE

a) gpib.address to change the address b) gpib.enable to change the enable setting.

ON: GPIB will respond to bus commands. OFF: GPIB will not respond to bus commands.

proper driver must be installed. Installing the Test Script Builder application also installs the applicable USB driver (it becomes available after installing this software). To complete the USB driver installation, after installing the Test Script Builder application, connect the Series 3700 USB connector (rear panel) to the computer.

Ethernet supports various settings. The LAN logical device has options that show the current status under lan.status commands while it has pending configuration settings under lan.config. The config settings will take effect when lan.applysettings is executed. Using the lan.reset command is equivalent to doing a lan.restoredefaults followed by a lan.applysettings. To only restore defaults without resetting to them, use the lan.restoredefaults command by itself. Please refer to the LAN ICLs directly for individual settings that may be controlled with the LAN logical device. From the front panel, the LAN (Ethernet) options may be enabled or disabled collectively under MAIN MENU and LAN settings. From the bus, one may enable or disable certain aspects of LAN with:

1. comm.lan.telnet.enable

2. comm.lan.web.enable

3. comm.lan.vxi11.enable

4. comm.lan.rawsockets.enable

Section 3: Rear Panel Series 3700 System Switch/Multimeter Quick Start Guide

3-12 Document Number: 3700S-903 -01 Rev. A / August 2007

The following list contains the four LAN default port numbers (along with corresponding ICLs to query for these values):

1. telnet is 23 (ICL: lan.status.port.telnet)

2. rawsocket is 5025 (ICL: lan.status.port.rawsocket)

3. vxi11 is 1024 (ICL: lan.status.port.vxi11)

4. dead socket termination is 5030 (ICL: lan.status.port.dst)

When changing between the various bus interfaces, send the abort command to have that interface become the active one for receiving and processing bus commands. For example, if changing from communicating with instrument over GPIB and to send ICLs with a telnet session (assuming both interfaces are enabled):

1. Connect via telnet.

2. Send abort to leave the GPIB interface and switch over to telnet.

3. Send commands as desired.

Any of the enable settings will take effect the next time the unit powers up. Therefore, after making changes to these settings, power cycle the unit.

Power-up

Line power connection

Follow the procedure below to connect the Series 3700 to line power and turn on the instrument. The Series 3700 operates from a line voltage of 100V to 240V at a frequency of 50Hz or 60Hz. Line voltage is automatically sensed. There are no switches to set. Make sure the operating voltage in your area is compatible.

WARNING The power cord supplied with the Series 3700 contains a separate ground

wire for use with grounded outlets. When proper connections are made, instrument chassis is connected to power line ground through the ground wire in the power cord. Failure to use a grounded outlet may result in personal injury or death due to electric shock.

CAUTION Operating the instrument on an incorrect line voltage may cause damage to the

instrument, possibly voiding the warranty.

How do I control switches?

NOTE This paragraph provides information for controlling switches using channel operation

(for channel pattern operation, refer to the Channel pattern operation paragraph contained in the User's manual). It contains information on opening and closing all switches from the front panel, as well as over the bus.

Close/open overview

NOTE This section provides basic close/open information for switching module channels.

Operating characteristics unique to a specific Series 3700 switching module are provided in an instruction sheet provided with the specific switching module.

Terminology used throughout this manual is detailed in the applicable sections of the

user's and reference manuals.

The switching channels of a Series 3700 support a concept of "duality." This means that each channel has specific settings for switching and specific settings for switching with DMM operations. The location of the specific operation request determines the setting that activates. An operation request residing in the channel logical device causes the switching settings to be used (example commands are channel.close, channel.open, channel.exclusiveclose); an operation request residing in the DMM logical device such as dmm.close or dmm.open, causes the DMM settings to be used. Refer to the reference manual for more information on logical devices (TSP section).

Open a Microsoft web-browser and type in the IP address (see How do I connect to the internal

web page? (on page 4-12) located in the Quick Start Guide). The Series 3700 home page will

appear. Use this home page to see a visual representation of the present channel status (select the desired slot or model contained under "Cards").

NOTE Java application may need to be installed.

The Series 3700 supports opening and closing channels through either Channel operation or through Channel pattern operation:

Channel operation (non-channel pattern operation): This mode of operation should be used exclusively by most (if not all) users. When you close a channel for a measurement operation, other channels on the switching module close automatically to internally connect it through the backplane to the DMM of the Series 3700. When you close a channel for a switching operation, the channel (and possibly the channel pair) will close but, no backplane relays are closed unless associated with the channel.

Channel pattern operation: This mode of operation provides additional flexibility by providing individual control of each switching module and backplane channel. Careless operation in this mode could create a safety hazard and/or damage the switching module and other equipment. Channel pattern operation should only be used by experienced test engineers.

that could result in severe injury or death. Improper operation can also cause damage to the switching modules and external circuitry. Controlling multiple channels using channel patterns should be restricted to experienced test engineers who recognize the dangers associated with multiple channel closures.

CAUTION To prevent damage to a switching module, do not exceed the maximum signal

level input for that module. Most switching modules are rated for 300V.

NOTE The Series 3700 is capable of scanning switching module channels. Each channel in

the scan can have its own unique DMM configuration.

The channel list parameter <ch_list>, used when controlling the Series 3700's relays over the bus, is a string-type parameter. An example:

 Channel 1 (of Slot 1) is associated with analog backplane relays 3 and 4, while Channel

3 (of the same slot) has analog backplane relays 5 and 6. The <ch_list> used in this example is ("1001, 1003"). The response to a channel.getbackplane("1001, 1003") will be "1913, 1914;1915,1916". To associate the backplane relays as indicated with Channel 1, the corresponding command would be channel.setbackplane('1001', '1913, 1914').

Therefore, when sending this parameter:

 Enclose the contents of the channel list in either single (') or double (") quotes, but the

quote style must match.

 Use a comma or semicolon to separate the channel list or channel patterns.  The string may contain a single channel, channel pattern or analog backplane relay as

well as multiple ones that are indicated by a range or comma separated.

 Use a colon to specify a range of channels. Example:

channel.getbackplane("1001:1003") responds with the range of Slot 1 channels from 1 to

Although a parameter string may be valid, the command that calls it will determine the string's ultimate validity. For example, only channels have a pole setting (channel patterns do not). If a channel pattern is passed to the poles setting command, an error would be generated.

Channel patterns may be included as a <ch_list> parameter.

<ch_list> queries

For queries that return a channel list parameter, a channel configured for 4-pole operations will indicate the paired channel in parenthesis. For example, Channel 3003 on a 60-channel card is configured for 4-pole, then sending:

channel.close('3003')

print(channel.getclose('slot3')  3003(3033)

NOTE In the above examples output the paired channel associated with 3003 is 3033 and

is in included in parenthesis.

GPIB interface connection

Use a shielded IEEE-488 cable such as the Keithley Instruments Model 7007 to connect the Series 3700 IEEE-488 connector to the GPIB connector on the control computer. Connect one end of the cable to the host computer and the other end to the Series 3700. Both cable connections (see item 1 in the figure titled "GPIB cable") are identical. The GPIB cable connectors are stackable. For additional non-Series 3700 GPIB instruments in the test system, daisy-chain a GPIB cable from one instrument to another.

NOTE To minimize interference caused by electromagnetic radiation, use only shielded GPIB

Figure 4-8: GPIB cable

cables. Available shielded cables from Keithley Instruments are the Model 7006 and Model 7007.

Refer to Rear panel summary (on page 3-1) for connector location.

Standard RJ-45 (Ethernet) interface connection

The Series 3700 uses a standard Ethernet connection configuration. It is designed for a 10/100BaseTX network using standard RJ-45 connectors. This is an eight wire connector, but only two sets of wire pairs are used: one pair to transmit and one pair to receive data. A 10BaseT network can accommodate transmission speeds up to 10Mbit per second where a 100BaseTX network operates at speeds of up to 100Mbit per second. Both types of networks usually require Ethernet hubs to make connections. The exception is a one-to-one connection using a crossover cable, which may be a 10BaseT or 100BaseTX dependent on the computer’s Ethernet interface card and which category of cable is used (the Series 3700 can be directly connected to a computer's NIC card using an Ethernet crossover cable). Refer to Rear panel

summary (on page 3-1) for connector location.

How do I use other programs?

NOTE Also see the LabVIEW® and Visual Basic documentation for details on using those

programs.

Test Script Builder is a tool for creating scripts. It includes built in color coding, debugging tools, and error handling. One way to interface with the Series 3700 is to use Test Script Builder to create scripts and store these scripts to non-volatile memory of the instrument. You can then call these scripts using the front panel LOAD menu or use the system test program to call user scripts or the functions these scripts create. Interfacing in this way may work well in situations where the output the only required output from the Series 3700 is digital output. However, in many situations, there is a need to gather some form of data from the Series 3700, whether that data be measurements or status information. Therefore, it is important that we now discuss how to use an external application development environment (ADE) to interface with the Series 3700. The discussion will center on the use of Visual Basic and LabVIEW, two of the most popular choices for ADE in the test and measurement industry. However, the concepts presented may be used in conjunction with other ADE.

Fundamentals when using other programs

After selecting the communication interface of your choice (GPIB, USB or Ethernet), consult the applicable reference material for the ADE to understand how to send and receive strings to/from the Series 3700 via this interface. For USB, you will need to understand how to send and receive strings using VISA TMC protocol. Please refer to National Instruments VISA User and Reference manuals.

Next, refer to the ICL commands to determine which strings the Series 3700 can interpret. Refer to the ICL commands contained in the Series 3700 reference manual.

Section 4: Frequently Asked Questions Series 3700 System Switch/Multimeter Quick Start Guide

4-22 Document Number: 3700S-903 -01 Rev. A / August 2007

Examples

Below is an example of how to send a reset command via GPIB in Visual Basic to a Model 3706 at GPIB address 16, using the Keithley/CEC GPIB card driver:

dim intStatus as integer

call Send (16, "reset()", intStatus)

This same example can be accomplished in LabVIEW using the GPIB vi. Below is an example of how to send a reset command via USB in Visual Basic. The example

below also shows the initialization of the VISA resource for clarity:

dim status as viStatus

dim vi as ViSession

dim strMsg as String

dim intRetCount as Integer

status = viOpen("USB0::0x05E6:0x3706::1234567::INSTR", VI_NULL, VI_NULL, vi)

strMsg = "reset()"

status = viWrite(vi, strMsg, Len(strMsg), intRetCount)

This same example can be implemented in LabVIEW® using VISA.

Using external programs with a script

A script is a simple combination of ICL and TSL commands. Remember that the Series 3700 has its own microprocessor and can compile and execute code. You will gain the greatest throughput using this method of distributed programming.

Test Script Builder (TSB) might be used to create and test scripts because its user interface offers several advantages including color coding, debugging tools, and error handling. However, you might wish for a third party ADE to handle the 'official' storing of scripts to the Series 3700 in a production test system. You can use the ADE of your choice to store debugged scripts to the instrument. To inform the Series 3700 that you are sending a script, you must surround the script with the commands loadscript and endscript. For more information on sending scripts to the instrument, please refer to the test script builder section contained in the Series 3700 reference manual.

Series 3700 System Switch/Multimeter Quick Start Guide Section 4: Frequently Asked Questions

Document Number: 3700S-903-01 Rev. A / August 2007 4-23

Below is an example of sending scripts to the Series 3700 at GPIB address in Visual Basic using the Keithley Instrument GPIB card:

Call Send (16, "loadscript TSPeasyExample", intStatus)

Call Send(16, "channel.close()", intStatus)

Call Send(16, "print(dmm.measure())", intStatus)

Prompts

Call send(16, "endscript", intStatus)

TSP prompts provide useful test script processor status information when loading and running scripts. Prompts can indicate when the Series 3700 has received a line of code and is awaiting other code for the script; prompts can also indicate if a script was received or executed successfully and when the script is complete; finally, a different prompt is returned when an error is generated, thus enabling much simpler error handling. If the TSP error prompt is received, the test program can then read the error queue and report back to the user.

It is important to remember, however, that if one desires to use prompts, then these prompts must be handled as soon as they are enabled. To enable prompts send the command localnode.prompts = 1.

Returning data from the Series 3700

Queries for TSP-based instruments do not end in a question mark as do SCPI instruments. Rather many of the commands can be converted to queries simply by whether or not you're assigning its result to a variable. The print statement is used to place the result of any ICL command function in the output queue of the Series 3700. This statement essentially serves as the query function for the Series 3700. The following example demonstrates how to use the Keithley Instruments GPIB card in Visual Basic to initiate and return a DMM measurement:

dim intNumBytes as Integer, intStatus as Integer

dim strReading as String

call Send (16, "print(dmm.measure())", intStatus)

call Enter(strReading, 1024, intNumBytes, 16, intStatus)

Similarly, any value can be printed at any time to the output queue using the print statement. One key advantage of this ability is that the user can set his own flag to indicate completion of a script or of a group of measurements. For instance, if the user wants to know when a script is completed, he can have the Series 3700 print "complete" on the last line of the script, and then the PC test program can poll the instrument until it receives the string "complete." An alternative way of notifying the end of a sweep is to use prompts. Please see prior section for more information.

There is one note of caution about printing results to the output queue. The output queue is limited to 32kB. If the amount of data to be sent to the output queue exceeds 32kB, then the Series 3700 will generate an error. Thus, it is important to remember that when returning large amounts of data from the instrument to do so by repetitively returning small groups of data at a time until all data has been returned. This is especially noteworthy when using the printbuffer command.

Questions about Test Script Processor interaction

What is a script?

A script is a collection of instrument control commands and programming statements to perform one or more operations or tasks. A script is stored in the Series 3700 and is run by its Test Script Processor (TSP).

User scripts

A user script is a script created by a user using the Test Script Builder or an external program. The user script is loaded in the Series 3700 and stored in volatile or nonvolatile memory. If stored in nonvolatile memory, the script will not be lost when the instrument is turned off.

Keithley Instruments will be posting approved user scripts donated by registered users on its web site. You will be able to download these user scripts into your Series 3700. Visit www.keithley.com for details.

How do I run a script from the front panel?

Load tests from the LOAD TEST menu (access this menu by pressing the front panel's LOAD key).

From the front panel, a user script may, or may not be interactive. A non-interactive script requires no operator input and will run to completion when it is started.

The USER menu item does not contain scripts, but may contain any executable Lua chunk (Chunk defined). The chunk is sent to TSP. It cannot automatically execute a script. The Lua chunk must be something like "S1()" where "S1" is a script. The menu SCRIPTS snapshots all scripts in volatile memory that can be executed directly.

LOAD key

Loads scripts, along with Lua chunks added with display.loadmenu.add for execution. This key opens the LOAD TEST menu which contains the following menu items:

 USER: This menu item provides access to Lua chunks specified by

display.loadmenu.add (not scripts).

 SCRIPTS: This menu item provides access to scripts created by the user. The scripts

can be directly executed.

Procedure to run scripts from front panel

1. Press the LOAD key to display the LOAD TEST menu.

2. Position the blinking cursor on the USER or SCRIPTS menu item and press the ENTER key (or the Wheel). Keep in mind that the Series 3700 is shipped with no user scripts loaded.

3. Position the blinking cursor on the test to be run.

4. Press the RUN key to start the test.

5. Enter any required test parameters using the front panel controls.

NOTE Test data can be stored in a buffer if a buffer is created and selected.

How do I interact with scripts from Test Script Builder?

Running a user script

Remote programming

To run a script using TSB Builder:

1. Enter the script in the script development pane.

2. Execute the script by right clicking on the script in development pane and select run as TSP file.

TSB Builder example: For example, the following script will exclusively close channels 1 to 60 on Slot 4 while printing

channels closed on Slot 4:

-- script to exclusively close channels 1 to 60 on Slot 4

for x = 4001, 4060 do

channel.exclusiveclose('' .. x) -- covert the channel number to string parameter

print(channel.getclose('slot4')) -- display channel closed on slot

end

Telnet session example: The following is an example from a telnet session that creates a script called slotquery that will

print out the identification strings of each module installed in a slot:

loadscript slotquery

>>>>

for x = 1, 6 do

>>>>

print(slot[x].idn)

>>>>

end

>>>>

endscript

Front panel operation

1. Press the EXIT key if not in local operation.

2. Press the LOAD key.

3. Select the SCRIPTS option.

4. Scroll through the list scripts and select (press the ENTER key). The script is now loaded for front panel use.

5. Press the RUN key to execute.

NOTE The previous front panel example does not display any print outputs. For example,

selecting the previous example (slotquery) to run will appear as nothing happened.

Deleting a user script

A user script can be deleted from non-volatile memory of the Series 3700. The following command will delete the slotquery user script:

script.delete("slotquery")
