Page 9: Overview
Remote Operation Overview This programming guide supports LCA models beginning with the B generation. These now include: N4373D, N7373C, N4373B, N4374B, N4375D, N4375B, N4376D and N4376B. This chapter will help you control an LCA from your own computer. The chapter covers how to write your own applications. - Page 10 Remote Operation In .NET remoting, the server program publishes an object on a network channel and the client program subscribes to that channel when loading or connecting to that object. In the case of the LCA, a RemoteObject object is published to an http channel and the subscribing client program is the LCA RemoteClient.

Page 11: Analyzer
Remote Operation While this chapter assumes you are familiar with your programming environment, it does not assume familiarity with controlling remote objects from within that environment. Examples are provided for VB.NET, C#, VB 6.0, VBA and Keysight VEE, which can be extrapolated to most environments for controlling the LCA. -
Page 12: Lca System Configuration
Because your network settings are unique to your IT infrastructure, N O TE Keysight Technologies will not be able to assist you with connecting your instrument to your network. Please contact your network administrator or IT department for assistance. For more information, refer to the MS Windows resource kit (available from Microsoft) that is appropriate for your computer system. - Page 13 Remote Operation By default, as the instrument starts up, you are logged on as an N O TE administrator with the logon name PNA-Admin. The login password, which is usually not needed, is "pna" for systems with Windows 7 or "agilent"...

Page 15: Install The Lca Remote Client
Remote Operation Install the LCA Remote Client The LCA Remote Client is described in “Overview” on page 6. This installation is not for the LCA itself. (Applications using the remote N O TE programming commands can be run on the LCA itself without installing the remote client package.) 1 If not already installed, install the .NET Framework Version 2.0 from Microsoft. -
Page 16: How To Use The Lca Remote Client
Remote Operation How to use the LCA Remote Client Here you can see the basic steps required to write an LCA client application. The code sequences presented here are in VB.NET syntax. For sequences in other languages like C#, VB 6.0, VBA or C++ refer to the different programming examples. - Page 17 Remote Operation 4 Select “RemoteClient.dll” and press OK. 5 If you also want to use the network analyzer COM interface, please refer to the network analyzer documentation, including: http://na.support.keysight.com/pna/programming/ Because environments like VB 6.0 or VBA cannot work directly with .NET assemblies, you have to use the COM interface of the LCA Remote Client in such cases.

Page 18: Declare And Create The Required Objects
Remote Operation In both programming environments you will see a dialog like the following: 2 Select“Keysight Remote Client for the LCA”. Declare and create the required objects The LCA Remote Client defines • three interfaces ILCARemoteClient, ILCAMeasParams, ILCAProperties and • three classes, LCARemoteClient, LCAMeasParams and LCAProperties. -
Page 19: Basic Structure Of An Lca Client Application
Remote Operation If you also want to use the network analyzer, you have to declare and create a network analyzer application object. This is quite different to the LCA. When working with the LCA you are creating a local LCA Remote Client object. The connection to the remote LCA server is done with the “Connect”... - Page 20 Remote Operation now you could call commands which do not require an open session. In the case of the LCA client, this is the GetLCAProperties command. lcaClient.GetLCAProperties(lcaProperties) 3 Open a session on the LCA, and check the return value of the Open() command.
-
Page 21: Synchronous Vs. Asynchronous Method Calls
Remote Operation Synchronous vs. Asynchronous Method Calls A traditional remote control application consists of a list of actions that you send to the instrument, expecting it to execute them in that order and to tell you when it is done. This makes programming easy - you can do your whole measurement in a single function or sub-routine. - Page 22 Remote Operation Using the OperationComplete() Property in a loop: oLCAClient.Init_OO(params, False) ‘ let the application handle events Application.DoEvents() System.Threading.Thread.Sleep(200) While oLCAClient.OperationComplete = False Using the WaitForOPC() command: oLCAClient.Init_OO(params, False) DoMyActionsAfterCallingInit() ‘ doing some other stuff ‘ When we are done with our own stuff, ‘...

Page 23: Troubleshooting
Remote Operation Troubleshooting During application development you may encounter situations where the Open() call fails. This happens when a session on the LCA is already open. If there are no other applications using the LCA, the most likely reason is that an application finished without closing its session, for example when running an application in the debugger and you terminate it by stopping the debugger. -
Page 24: Lca Remote Programming
Remote Operation LCA Remote Programming The LCA remote programming interface uses Microsoft.NET Remoting technology. It is controlled by manipulating the properties and methods exposed by the server object. The list of properties and methods in this section describe the interface that is available to a programmer wanting to program the LCA system in other applications. -
Page 25: Specific Commands
Remote Operation Specific Commands Interface structure There are three classes to control the LCA: the LCAMeasParams, the LCAProperties and the LCARemoteClient. • The class LCAMeasParams summarizes all possible parameters of your measurement. • The class LCAProperties provides read-only properties, which give you some information about the network analyzer and the LCA. -

Page 31: Interface Ilcaremoteclient
Remote Operation Interface ILCARemoteClient General commands Sub Connect (ByVal server As String) Create a connection to an LCA server application. An LCA client application can only have one open connection to an LCA server at any time. The LCA server could handle several open connections concurrently. - Page 32 Remote Operation All actions allowed in a passive session are also allowed in an active session. Parameters: No parameters. Return value: Boolean True: A session has been opened False: Opening a session failed Function OpenPassive () As Boolean Opens an passive session on the LCA. All commands that just read settings from the LCA require at least an open passive session.
- Page 33 Remote Operation This can be useful if an abandoned, open session prevents a successful Open() command. However, be careful not to disturb any other connected client applications. The LCA automatically closes abandoned sessions after some time (>60s) of inactivity. Parameters: No parameters.
-
Page 34: Measurement Commands
Remote Operation If you are using the LCA Remote Client .NET assembly directly, you can also specify the timeout value in the LCARemoteClient constructor. When using the COM interface you could only use the default constructor, so you have to use this command to specify a non- default timeout value. - Page 35 Remote Operation Sub Init_EO (ByVal parameters As RemoteClient.ILCAMeasParams, ByVal sync As Boolean) Initializes the LCA for an EO measurement. Parameters: ByVal parameters As RemoteClient.ILCAMeasParams The measurement parameters for initialization Optional ByVal sync As Boolean True (default): the call is blocked until initialization is complete False: the call returns immediately.
- Page 36 Remote Operation Sub Init_OO (ByVal parameters As RemoteClient.ILCAMeasParams, ByVal sync As Boolean) Initializes the LCA for an OO measurement. Parameters: ByVal parameters As RemoteClient.ILCAMeasParams The measurement parameters for initialization Optional ByVal sync As Boolean True (default): the call is blocked until initialization is complete False: the call returns immediately.
- Page 37 Remote Operation Sub LoadOOTxCalData (ByVal parameters As RemoteClient.ILCAMeasParams, ByVal filename As String, ByVal sync As Boolean) Use this command instead of Init_OE if you want the LCA to load and use previously saved user calibration data. The loaded user calibration data will be used by the LCA until the next initialization command is called.
- Page 38 Remote Operation The loaded user calibration data will be used by the LCA until the next initialization command is called. See also: SaveUserCalData Parameters: ByVal parameters As RemoteClient.ILCAMeasParams The measurement parameters for initialization ByVal filename As String The name of the file containing the user calibration data Optional ByVal sync As Boolean True (default): the call is blocked until initialization...
- Page 39 Remote Operation For synchronization use the synchronization methods WaitForOPC or OperationComplete. Parameters: ByVal continuous As Boolean True: measurements are done continuously False (default): a single measurement is triggered Optional ByVal sync As Boolean True (default): the call is blocked until initialization is complete False: the call returns immediately.

Page 43: The Lca Scpi Interface
Remote Operation The LCA SCPI Interface Overview The LCA instrument is a combined instrument. It is a network analyzer with additional hardware and software to become the LCA. The network analyzer already offers a SCPI interface on different ports. Now the new LCA SCPI interface extends the existing LCA application. - Page 44 Remote Operation You always have to run the network analyzer application to get the LCA functionality. Therefore if you only run the network analyzer and NOT the LCA SCPI interface, the USB device port is taken by the network analyzer SCPI talker/listener. When you first connect your PC with a USB cable to the LCA (combined instrument), you get the Network Analyzer identification string if you send the *IDN? query.

Page 45: Configuration
Remote Operation Configuration Select the communication port for your LCA SCPI interface, either the LAN socket port 5026 or the USB device port. Run the Agilent.LCA.SCPI.Config.exe program or click on the LCA SCPI Configuration shortcut on the network analyzer macro list to select the preferred port. -
Page 46: The Lca Scpi Commands
Remote Operation The LCA SCPI interface is implemented on the LCA Remote Interface methods and the Agilent Translator Framework. Therefore the LCA Server starts automatically when you start the LCA SCPI interface. When you click on the “Start SCPI” button on the SCPI configuration form, the Agilent Translator Framework starts and loads the Agilent.LCA.SCPI.Module. - Page 47 Remote Operation :NWA:MODel? -> <string> :NWA:PORT:NUMBer? -> <integer> *OPC? -> <0|1> as string :PARameter:ADVAnced:MODE /? -> <0|1> as string :PARameter:ELECtrical:PATH:DEEMbedding /? -> <0|1> as string :PARameter:ELECtrical:RECeiver:S2PFile[n] /? <string> (index n = 1|2) :PARameter:ELECtrical:SOURce:S2PFile[n] /? -> <string > (index n = 1|2) :PARameter:MEASurement:MODE /? ->...
