5 Write Your Own Application

In order to write your own application, you need a specific instrument driver and some tools for use in different programming environments. The driver and tools are included in the installer package and cannot be found as separate files on the installation CD.

In this section the location of drivers and files, required for programming in different environments, are given for installation under Windows XP (32 bit) and Windows 7 (32 and 64 bit)

Note

PM400 software and drivers contains 32 bit and 64 bit applications. In 32 bit systems, only the 32 bit components are installed to

C:\Program Files\...

In 64 bit systems the 64 bit components are being installed to

C:\Program Files\...

while 32 bit components can be found at

C:\Program Files (x86)\...

In the table below you will find a summary of what files you need for particular programming environments.

Note

All above environments require also the NI VISA instrument driver dll ! During NI-VISA Runtime installation, a system environment variable VXIPNPPATH for including

files is created. It contains the information where the drivers are installed to, usually to C: \Program Files\IVI Foundation\VISA\WinNT\.

This is the reason, why after installation of a NI-VISA Runtime a system reboot is required: This environment variable is necessary for installation of the instrument driver software components.

5.5 SCPI Commands

This section describes in detail the SCPI command set with respect to PM400 power meter console. However, these commands are compatible with PM100A, PM100D and PM100USB consoles as well as with the PM160 Hand-held Power Meter, except some console and sensor related functions.

5.5.1 An Introduction to the SCPI language

The PM400 interface commands use the SCPI (Standard Commands for Programmable Instruments), an ASCII-based command language that was designed for test and measurement instruments.

SCPI commands are based on a hierarchical structure, also known as a tree system. In this system, associated commands are grouped together under a common node or root, thus forming subsystems. A portion of the SENSE subsystem is shown below to illustrate the tree system.

SENSe:

CORRection :COLLect :ZERO [:INITiate] :ABORt :STATe? :MAGNitude? :BEAMdiameter {MINimum|MAXimum|DEFault|<numeric_value>[mm]} :BEAMdiameter? [{MINimum|MAXimum|DEFault}] :WAVelength {MINimum|MAXimum|<numeric_value>[nm]} :WAVelength? [{MINimum|MAXimum}] :POWer [:PDIode] [:RESPonse] MINimum|MAXimum|DEFault|<numeric_value>[A]} [:RESPonse]? [{MINimum|MAXimum|DEFault}] :THERmopile [:RESPonse] {MINimum|MAXimum|DEFault|<numeric_value>[V]} [:RESPonse]? [{MINimum|MAXimum|DEFault}]

SENSe is the root keyword of the command, CORRection is the second-level keyword, and

COLLect and BEAMdiameter are third-level keywords, and so on.

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

Command Format

The format used to show commands in this manual is shown below:

CURRent[:DC]:RANGe {MINimum|MAXimum|<numeric_value>[A]} CORRection:BEAMdiameter {MINimum|MAXimum|DEFault|<numeric_value>[mm]}

The command syntax shows most commands (and some parameters) as a mixture of upperand lower-case letters. The upper-case letters indicate the abbreviated spelling for the com-

mand. For shorter program lines, send the abbreviated form. For better program readability, send the long form.

For example, in the above syntax statement, CURR and CURRENT are both acceptable forms. You can use upper- or lower-case letters. Therefore, CURRENT, current and Current are all acceptable. Other forms, such as CUR and CURREN, will generate an error.

Page 45

5 Write Your Own Application

Braces ( { } ) enclose the parameter choices for a given command string. The braces are not sent with the command string. A vertical bar ( | ) separates multiple parameter choices for a given command string.

Triangle brackets ( < > ) indicate that you must specify a value for the enclosed parameter. For example, the above syntax statement shows the range parameter enclosed in triangle brackets. The brackets are not sent with the command string. You must specify a value for the parameter (such as "CURR:DC:RANG 50E-6").

Some parameters are enclosed in square brackets ( [ ] ). The brackets indicate that the parameter is optional and can be omitted. The brackets are not sent with the command string. In this example [:DC] can be omitted, so the command string can be shortened to “CURR:RANG 50E-6”. If you do not specify a value for an optional parameter, the power/energy meter chooses a default value.

Command Separators

A colon ( : ) is used to separate a command keyword from a lower-level keyword. You must insert a blank space to separate a parameter from a command keyword. If a command requires more than one parameter, you must separate adjacent parameters using a comma as shown below:

"SYST:TIME 10, 34, 48"

A semicolon ( ; ) is used to separate commands within the same subsystem, and can also minimize typing. For example, sending the following command string:

"CORR:BEAM 1; WAV 1310"

... is the same as sending the following two commands:

"CORR:BEAM 1" "CORR:WAV 1310"

Use a colon and a semicolon to link commands from different subsystems. For example, in the following command string, an error is generated if you do not use both the colon and semicolon:

"CORR:BEAM 1;:AVER 300"

Using the MIN and MAX Parameters

You can substitute MINimum or MAXimum in place of a parameter for many commands. For ex- ample, consider the following command:

CURRent[:DC]:RANGe {MINimum|MAXimum|<numeric_value>[A]}

Instead of selecting a specific current range, you can substitute MIN to set the range to its minimum value or MAX to set the range to its maximum value.

Querying Parameter Settings

You can query the current value of most parameters by adding a question mark (?) to the command. For example, the following command sets the operating wavelength to 1550 nm:

"CORR:WAV 1550"

You can query the operating wavelength by executing: "CORR:WAV?". You can also query the minimum or maximum operating wavelength allowed as follows:

"CORR:WAV? MIN" "CORR:WAV? MAX"

Caution

If you send two query commands without reading the response from the first, and then attempt to read the second response, you may receive some data from the first response followed by the complete second response. To avoid this, do not send a query command without reading

Page 46

PM400

the response. When you cannot avoid this situation, send a device clear before sending the second query command.

SCPI Command Terminators

A command string sent to the power/energy meter must terminate with a <new line> character. The IEEE-488 EOI (end-or-identify) message is interpreted as a <new line> character and can be used to terminate a command string in place of a <new line> character. A <carriage return> followed by a <new line> is also accepted. Command string termination will always reset the current SCPI command path to the root level.

IEEE488.2 Common Commands

The IEEE-488.2 standard defines a set of common commands that perform functions like reset, self-test, and status operations. Common commands always begin with an asterisk (*), are four to five characters in length, and may include one or more parameters. The command keyword is separated from the first parameter by a blank space. Use a semicolon (;) to separate multiple commands as shown below:

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

SCPI Parameter Types

The SCPI language defines several different data formats to be used in program messages and response messages.

Numeric Parameters Commands that require numeric parameters will accept all commonly used decimal representations of numbers including optional signs, decimal points, and scientific notation.

Special values for numeric parameters like MINimum, MAXimum and DEFault are also accepted. You can also send engineering unit suffixes with numeric parameters (e.g., M,K, or u). If only specific numeric values are accepted, the power/energy meter will automatically round the input numeric parameters. The following command uses a numeric parameter:

POWer:REFerence {MINimum|MAXimum|DEFault|<numeric_value>[W]}

Discrete Parameters Discrete parameters are used to program settings that have a limited number of values (like W,DBM). They can have a short form and a long form just like command keywords. You can mix upper- and lower-case letters. Query responses will always return the short form in all upper-case letters. The following command uses discrete parameters:

POW:UNIT {W|DBM}

Boolean Parameters Boolean parameters represent a single binary condition that is either true or false. For a false condition, the power/energy meter will accept “OFF” or “0”. For a true condition, the meter will accept “ON” or “1”. When you query a boolean setting, the instrument will

always return “0” or “1”. The following command uses a boolean parameter: CURRent:RANGe:AUTO {OFF|0|ON|1}

String Parameters String parameters can contain virtually any set of ASCII characters. A string

must begin and end with matching quotes; either with a single quote or with a double quote. You can include the quote delimiter as part of the string by typing it twice without any characters in between. The following command uses a string parameter:

DIAG:CALString <quoted string>

5.5.2 IEEE488.2 Common Commands

Common commands are device commands that are common to all devices according to the IEEE488.2 standard. These commands are designed and defined by this standard. Most of the commands are described in detail in this section. The following common commands associated with the status structure are covered in the “Status Structure” section: *CLS, *ESE, *ESE?, *ESR?, *SRE, *SRE?, *STB?

5.5.2.1 Command Summary

Page 48

PM400

5.5.2.2 Command Reference *IDN? – identification query - read identification code

The identification code includes the manufacturer, model code, serial number, and firmware revision levels and is sent in the following format: THORLABS,MMM,SSS,X.X.X

Where: MMM is the model code

SSS is the serial number X.X.X is the instrument firmware revision level

*OPC – operation complete - set OPC bit *OPC? – operation complete query – places a “1” in output queue

When *OPC is sent, the OPC bit in the Standard Event Register will set after all pending command operations are complete. When *OPC? is sent, an ASCII “1” is placed in the Output Queue after all pending command operations are complete.

Typically, either one of these commands is sent after the INITiate command. The INITiate command is used to take the instrument out of idle in order to perform measurements. While operating within the trigger model layers, many sent commands will not execute. After all programmed operations are completed, the instrument returns to the idle state at which time all pending commands (including *OPC and/or *OPC?) are executed. After the last pending command is executed, the OPC bit and/or an ASCII “1” is placed in the Output Queue. When *OPC is sent, the OPC bit in the Standard Event Register will set after all pending command operations are complete. When *OPC? is sent, an ASCII “1” is placed in the Output Queue after all pending command operations are complete.

*RST – reset – return instrument to defaults

When the *RST command is sent, the instrument performs the following operations:

Returns the instrument to the default conditions

Cancels all pending commands.

Cancels response to any previously received *OPC and *OPC? commands.

*TST? – self-test query – run self test and read result

Use this query command to perform the instrument self-test routine. The command places the coded result in the Output Queue. A returned value of zero (0) indicates that the test passed, other values indicate that the test failed.

*WAI – wait-to-continue – wait until previous commands are completed

The *WAI command is a no operation command for the instrument and thus, does not need to be used. It is there for conformance to IEEE488.2.

7.7 Thorlabs 'End of Life' Policy

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the European Community and the corresponding national laws, Thorlabs GmbH offers all end users in the EC the possibility to return “end of life” units without incurring disposal charges.

This offer is valid for Thorlabs GmbH electrical and electronic equipment

sold after August 13th 2005

marked correspondingly with the crossed out “wheelie bin” logo (see figure below)

sold to a company or institute within the EC

currently owned by a company or institute within the EC

still complete, not disassembled and not contaminated

As the WEEE directive applies to self contained operational electrical and electronic products, this “end of life” take back service does not refer to other Thorlabs GmbH products, such as

pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM laser driver cards)

components

mechanics and optics

left over parts of units disassembled by the user (PCB’s, housings etc.).

Waste treatment on your own responsibility

If you do not return an “end of life” unit to Thorlabs GmbH, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.

WEEE Number (Germany) : DE97581288

Ecological background

It is well known that waste treatment pollutes the environment by releasing toxic products during decomposition. The aim of the European RoHS Directive is to reduce the content of toxic substances in electronic products in the future.

The intent of the WEEE Directive is to enforce the recycling of WEEE. A controlled recycling of end-of-life products will thereby avoid negative impacts on the environment.
