1.Programming Overview

The Siglent SVA1000X series spectrum analyzers features LAN, USB Device, and SIGLENT GPIB_USB module interfaces. By using a computer with these interfaces, and a suitable programming language (and/or NI-VISA software), users can remotely control the analyzer based on SCPI (Standard Commands for Programmable Instruments) command set, Labview and IVI (Interchangeable Virtual Instrument), to interoperate with other programmable instruments.

This chapter introduces how to build communication between the spectrum analyzer and a controller computer with these interfaces.

1.1 Remotely Operating the Analyzer

The analyzer provides both the USB and LAN connection which allows you to set up a remote operation environment with a controller computer. A controller computer could be a personal computer (PC) or a minicomputer. Some intelligent instruments also function as controllers.

Now the installation is complete, reboot your PC.

1.2.2 Build Communication Using Sockets/Telnet

Through the LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate with the spectrum analyzer. VXI-11 is provided in NI-VISA, while Sockets and Telnet are commonly included in PC’s OS initially.

Socket LAN is a method used to communicate with the spectrum analyzer over the LAN interface using the Transmission Control Protocol/Internet Protocol (TCP/IP). A socket is a fundamental technology used for computer networking and allows applications to communicate using standard mechanisms built into network hardware and operating systems. The method accesses a port on the spectrum analyzer from which bidirectional communication with a network computer can be established.

Before you can use sockets LAN, you must select the analyzer’s sockets port number to use:

 Standard mode. Available on port 5025. Use this port for programming.  Telnet mode. The telnet SCPI service is available on port 5024.

2.SCPI Overview

2.1 Command Format

SCPI commands present a hierarchical tree structure containing multiple subsystems, each of the subsystems is made up of a root keyword and several subkeywords. The command string usually starts with “:”, the keywords are separated by “:” and the followed parameter settings are separated by space. Query commands add “?” at the end of the string.

For example: :SENSe:FREQuency:CENTer <freq> :SENSe:FREQuency:CENTer? SENSe is the root key of the command, FREQuency and CENTer are second and third

keywords. The command begins with “:”, and separates the keywords at the same time, <freq> separated by space and represents the parameter available for setting; “?” represents a query.

2.2 Symbol Instruction

The following four symbols are not the content of SCPI commands and cannot be sent with the commands, but are usually used in the commands.

1. Triangle Brackets < >

The parameter in the triangle brackets must be replaced by an effective value. For example: Send the “:DEMod:VOLume <value>” command in “:DEMod:VOLume 5”.

2. Square Brackets [ ]

The content in the square brackets can be ignored. When the parameter is ignored, the instrument will set the parameter to its default. For example,

In the “[:SENSe]:POWer[:RF]:ATTenuation?” command, sending any of the four commands below can generate the same effect:

:POWer:ATTenuation? :POWer:RF:ATTenuation? :SENSe:POWer:ATTenuation? :SENSe:POWer:RF:ATTenuation?

3. Vertical Bar |

The vertical bar is used to separate multiple parameters and when sending the command, you can choose one of the parameters. For example,

12 SVA1000X Programming Guide

Page 13

SIGLENT

In the “[:SENSe]:FREQuency:CENTer:STEP:AUTO OFF|ON|0|1” command, the parameters available are “OFF”, “ON”, “0” or “1”.

4. Braces { }

The parameters in the braces are optional which can be ignored or set for one or more times. For example：

:CALCulate:LLINe[1]|2:DATA <x-axis>,<ampl>{,<x-axis>, <ampl>}, in the command, the {,<x-

axis>, <ampl>} parameters can be ignored or set for one or more times.

2.3 Parameter Type

The parameters in the commands introduced in this manual include 6 types: boolean, enumeration, integer, float, discrete and string.

1. Boolean

The parameters in the commands could be “OFF”, “ON”, “0” or “1”. For example:

[:SENSe]:FREQuency:CENTer:STEP:AUTO OFF|ON|0|1

2. Enumeration

The parameter could be any of the values listed. For example:

[:SENSe]:AVERage:TYPE LOGPower|POWer|VOLTage

The parameter is “OGPower”, “POWer” or “VOLTage”.

3. String

The parameter should be the combinations of ASCII characters. For example:

:SYSTem:COMMunicate:LAN:IPADdress <“xxx.xxx.xxx.xxx”>

The parameter can be set as “192.168.1.12” string.

4. Integer

Except other notes, the parameter can be any integer within the effective value range. For example:

[:SENSe]:DEMod:VOLume <value>

The parameter < value > can be set to any integer between 0 and 10.

5. Float

The parameter could be any value within the effective value range according to the accuracy requirement (the default accuracy contains up to 9 digits after the decimal points). For example:

:CALCulate:BANDwidth:NDB <value> The parameter < value > can be set to any real number between -100 and 100.

SVA1000X Programming Guide 13

Page 14

SIGLENT

6. Discrete

The parameter could only be one of the specified values and these values are discontinuous. For

example: [:SENSe]:BWIDth:VIDeo:RATio <number>

The parameter <number> could only be one of 0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1.0, 3.0, 10.0,

30.0, 100.0, 300.0, 1000.0.

2.4 Command Abbreviation

All of the commands are not case sensitive, so you can use any of them. But if abbreviation is used, all the capital letters in the command must be written completely. For example:

:DISPlay:WINDow:TRACe:Y:DLINe:STATe? Can be abbreviated to: :DISP:WIND:TRAC:Y:DLIN:STAT?

Parameter Range

NEGative: Negative peak detection displays the lowest sample taken during the interval being displayed. POSitive: Positive peak detection displays the highest sample taken during the interval being displayed. SAMPle: Sample detection displays the sample taken during the interval being displayed, and is used primarily to display noise or noise-like signals. In sample mode, the instantaneous signal value at the present display point is placed into memory. This detection should not be used to make the most accurate amplitude measurement of non noise-like signals. AVERage: Average detection is used when measuring the average value of the amplitude across each trace interval (bucket). The averaging method used by the average detector is set to either video or power as appropriate when the average type is auto coupled. NORMAL: Normal detection selects the maximum and minimum video signal

values alternately. When selecting Normal detection,”Norm”appears in the

upper-left corner. QUASi: Quasipeak detection is a form of detection where a signal level is weighted based on the repetition frequency of the spectral components making up the signal. That is to say, the result of a quasi-peak measurement depends on the repetition rate of the signal.

4.Programming Examples

This chapter gives some examples for the programmer. In these examples you can see how to use the VISA or sockets, in combination with the commands have been described above to control the spectrum analyzer. By following these examples, you can develop many more applications.

4.1 Examples of Using VISA

4.1.1 Example of VC++

Environment: Win7 32bit system, Visual Studio The functions of this example: use the NI-VISA, to control the device with USBTMC or

TCP/IP access to do a write and read. Follow the steps to finish the example:

1、 Open Visual Studio, create a new VC++ win32 console project. 2、 Set the project environment to use the NI-VISA lib, there are two ways to use NI-VISA,

static or automatic:

1) Static: find files: visa.h, visatype.h, visa32.lib in NI-VISA install path. Copy them to your project, and add them into project. In the projectname.cpp file, add the follow two lines:

#include "visa.h" #pragma comment(lib,"visa32.lib")

2) Automatic:

Set the .h file include directory, the NI-VISA install path, in our computer we set the path is: C:\Program Files\IVI Foundation \VISA\WinNT\include. Set this path to project---properties--c/c++---General---Additional Include Directories: See the picture.

Set lib path set lib file: Set lib path: the NI-VISA install path, in our computer we set the path is: C:\Program Files\IVI

Foundation\VISA\WinNT \lib\msc. Set this path to project---properties---Linker---General---Additional Library

Directories: as seen in the pictures below.

Existing Item. Search for the visa32.bas file in the include folder under the NI-VISA installation path and add the file.

This allows the VISA functions and VISA data types to be used in a program. 3、 Add codes:

1) USBTMC access code:

Write a function Usbtmc_test:

Private Function Usbtmc_test() As Long

' This code demonstrates sending synchronous read & write commands ' to an USB Test & Measurement Class (USBTMC) instrument using ' NI-VISA ' The example writes the "*IDN?\n" string to all the USBTMC ' devices connected to the system and attempts to read back ' results using the write and read functions. ' The general flow of the code is ' Open Resource Manager ' Open VISA Session to an Instrument ' Write the Identification Query Using viWrite ' Try to Read a Response With viRead ' Close the VISA Session

Const MAX_CNT = 200 Dim defaultRM As Long

Dim instrsesn As Long Dim numlnstrs As Long Dim findList As Long Dim retCount As Long

Dim status As Long Dim instrResourceString As String * VI_FIND_BUFLEN Dim Buffer As String * MAX_CNT Dim i As Integer

' First we must call viOpenDefaultRM to get the manager ' handle. We will store this handle in defaultRM.

status = viOpenDefaultRM(defaultRM)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Could not open a session to the VISA Resource Manager!" Usbtmc_test = status Exit Function

End If

' Find all the USB TMC VISA resources in our system and store the ' number of resources in the system in numInstrs.

If (status < VI_SUCCESS) Then

resultTxt.Text = "An error occurred while finding resources." viClose (defaultRM) Usbtmc_test = status

Exit Function End If

' Now we will open VISA sessions to all USB TMC instruments. ' We must use the handle from viOpenDefaultRM and we must ' also use a string that indicates which instrument to open. This ' is called the instrument descriptor. The format for this string ' can be found in the function panel by right clicking on the ' descriptor parameter. After opening a session to the ' device, we will get a handle to the instrument which we ' will use in later VISA functions. The AccessMode and Timeout ' parameters in this function are reserved for future ' functionality. These two parameters are given the value VI_NULL.

For i = 0 To numInstrs If (i > 0) Then

status = viFindNext(findList, instrResourceString)

End If

status = viOpen(defaultRM, instrResourceString, VI_NULL, VI_NULL, instrsesn)

If (status < VI_SUCCESS) Then resultTxt.Text = "Cannot open a session to the device " + CStr(i + 1)

GoTo NextFind

End If

' At this point we now have a session open to the USB TMC instrument. ' We will now use the viWrite function to send the device the string "*IDN?", ' asking for the device's identification.

status = viWrite(instrsesn, "*IDN?", 5, retCount)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Error writing to the device." status = viClose(instrsesn) GoTo NextFind

End If

' Now we will attempt to read back a response from the device to ' the identification query that was sent. We will use the viRead ' function to acquire the data. ' After the data has been read the response is displayed.

status = viRead(instrsesn, Buffer, MAX_CNT, retCount)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Error reading a response from the device." + CStr(i + 1)

Else

resultTxt.Text = "Read from device: " + CStr(i + 1) + " " + Buffer

End If

status = viClose(instrsesn)

Next i

' Now we will close the session to the instrument using ' viClose. This operation frees all system resources.

status = viClose(defaultRM) Usbtmc_test = 0

End Function

2) TCP/IP access code:

Write a function TCP_IP_Test:

Private Function TCP_IP_Test(ByVal ip As String) As Long Dim outputBuffer As String * VI_FIND_BUFLEN Dim defaultRM As Long Dim instrsesn As Long Dim status As Long

74 SVA1000X Programming Guide

Dim count As Long

' First we will need to open the default resource manager.

status = viOpenDefaultRM (defaultRM)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Could not open a session to the VISA Resource Manager!" TCP_IP_Test = status Exit Function

End If

' Now we will open a session via TCP/IP device

status = viOpen(defaultRM, "TCPIP0::" + ip + "::INSTR", VI_LOAD_CONFIG, VI_NULL, instrsesn)

If (status < VI_SUCCESS) Then resultTxt.Text = "An error occurred opening the session"

viClose (defaultRM) TCP_IP_Test = status

Exit Function End If

status = viWrite(instrsesn, "*IDN?", 5, count)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Error writing to the device."

End If

status = viRead(instrsesn, outputBuffer, VI_FIND_BUFLEN, count)

If (status < VI_SUCCESS) Then

resultTxt.Text = "Error reading a response from the device." + CStr(i + 1)

Else

resultTxt.Text = "read from device:" + outputBuffer

End If

status = viClose(instrsesn) status = viClose(defaultRM) TCP_IP_Test = 0

End Function

3) Button control code:

Private Sub exitBtn_Click()

End

End Sub Private Sub tcpipBtn_Click()

Dim stat As Long stat = TCP_IP_Test(ipTxt.Text) If (stat < VI_SUCCESS) Then resultTxt.Text = Hex(stat) End If

End Sub Private Sub usbBtn_Click()

Dim stat As Long stat = Usbtmc_test If (stat < VI_SUCCESS) Then resultTxt.Text = Hex(stat) End If

1) USBTMC access code :

Write a function Usbtmc_test.

function USBTMC_test()

% This code demonstrates sending synchronous read & write commands % to an USB Test & Measurement Class (USBTMC) instrument using % NI-VISA

%Create a VISA-USB object connected to a USB instrument

vu = visa('ni','USB0::0xF4ED::0xEE3A::sdg2000x::INSTR');

%Open the VISA object created

fopen(vu);

%Send the string "*IDN?",asking for the device's identification.

fprintf(vu,'*IDN?');

%Request the data

outputbuffer = fscanf(vu); disp(outputbuffer);

%Close the VISA object

fclose(vu); delete(vu); clear vu;

end

2) TCP/IP access code:

Write a function TCP_IP_Test:

function TCP_IP_test()

% This code demonstrates sending synchronous read & write commands % to an TCP/IP instrument using NI-VISA

%Create a VISA-TCPIP object connected to an instrument %configured with IP address.

vt = visa('ni',['TCPIP0::','10.11.13.32','::INSTR']);

%Open the VISA object created

4.1.4 Example of LabVIEW

Environment: Win7 32bit system, LabVIEW 2011 The functions of this example: use the NI-VISA, to control the device with USBTMC and

TCP/IP access to do a write and read. Follow the steps to complete the example:

1、 Open LabVIEW, create a VI file. 2、 Add controls. Right-click in the Front Panel interface, select and add VISA resource

name, error in, error out and some indicators from the Controls column. 3、 Open the Block Diagram interface. Right-click on the VISA resource name and you can

select and add the following functions from VISA Palette from the pop-up menu: VISA Write, VISA Read, VISA Open and VISA Close.

4、 Connect them as shown in the figure below

5、 Select the device resource from the VISA Resource Name list box and run the program.

In this example, the VI opens a VISA session to a USBTMC device, writes a command to the device, and reads back the response. In this example, the specific command being sent is the device ID query. Check with your device manufacturer for the device command set. After all communication is complete, the VI closes the VISA session.

6、 Communicating with the device via TCP/IP is similar to USBTMC. But you need to

change VISA Write and VISA Read Function to Synchronous I/O. The LabVIEW default is asynchronous I/O. Right-click the node and select Synchronous I/O Mod>>Synchronous from the shortcut menu to write or read data synchronously.
