Memory

Hard Disk

512 MB of memory. Approximately 2 GB of available hard-disk space for the recommended

installation, which includes full TekExpress installation and distributed components.

Drive DVD drive

Display

Super VGA resolution or higher video adapter (800x600 minimum video resolution for small fonts or 1024x768 minimum video resolution for large fonts). The application is best viewed at 96 dpi display settings

Software TekExpress Framework (v1.4.6 or later) installed.

SigTest 3.1.30 or later installed.

DPOJET Jitter and Eye Analysis Tool (v3.4.0 or later) with Advanced Jitter

If TekExpress is running o n an instrument that has a video resolution lower than 800x600 (for example, sampling oscilloscope), it is recommended to connect a secondary monitor and this has to be enabled before launching the application.

If TekExpress is installed on a Tektronix oscilloscope, the virtual GPIB port cannot be used by TekExpress for communicating with oscilloscope applications. If external devices like USB-GPIB or equivalent are used for instrument connectivity, ensure that the Talker Listener utility is enabled in the

Deskew values in these cases may be as much as 30 ps or more.

Server and Client Proxy Objects

Remote Pr

The server exposes a remote object to let the remote client access and perform the server side operations remotel

The following is an example:

RemotingConfiguration.RegisterWellKnownServiceType (typeof (TekExpressRemoteInterface), “TekExpress Remote interface”, WellKnownObjectMode.S ingleton);

This object lets the remote client access the interfaces exposed at the server side. The client gets the reference to this object when the client gets connected to the server.

oxy Object

y. The proxy object is instantiated and exposed at the server-end through marshalling.

For example,

//Get a reference to the remote object

remoteObject = (IRemoteInterface)Activator.GetObje ct(typeof(IRemoteInterface), URL.ToString());

TekExpress Programmatic Interface Server and Client Proxy Objects

Client Proxy O

Client exposes a proxy object to receive certain information.

For examp

//Register the client proxy object

WellKnownServiceTypeEntry[] e = RemotingConfiguration.GetRegisteredWellKnownServiceTypes();

clientInterface = new ClientInterface();

RemotingConfiguration.RegisterWellKnownServiceType(typeof(ClientInterface), “Remote Client Interface”, WellKnownObjectMode.Singleton);

bject

le,

//Expose the client proxy object through marshalling

RemotingServices.Marshal(clientInterface, "Remote Client Interface");

The client proxy object is used for the following:

1. To g

et the secondary dialog messages from the server.

2. To get the ﬁle transfer commands from the server while transferring the report.

clientObject.clientIntf.DisplayDialog(caption, msg,iconType, btnType);

clientObject.clientIntf.TransferBytes(buffer, read, fileLength);

Secondary Dialog Message Handling

The secondary dialog messages from the Secondary Dialog library are redirected to the client-end when a client is performing the automations at the remote end.

In the secondary dialog library, the assembly that is calling for the dialog box to be displayed is checked and if a remote connection is detected, the messages are directed to the remote end.

File Transfer Events

When the client requests the transfer of the report, the server reads the report and transfers the ﬁle by calling the ﬁle transfer methods at the client-end.

Conne

Connect(string ipAddress, IRemoteClientIn terface clientIntf, out string clientID)

This method connects the client to the server. The client provides the ip address of the server to connect to the server. The server provides a unique clientId when the client is connected to it.

Troubleshooting Instrument Connectivity

Instrument Connectivity

If the instrument(s) are displayed in TekVISA Instrument Manager but not in the TekExpress Instrument Bench, check the following:

Only those instruments that respond to *idn? and *opt? queries successfully, are displayed in Instrument Bench.

Ensure that VXI-11 Server is running on the instruments.

If Instrument initialization fails during test sequence execution, do the following:

It is observed that GPIB communication with instrument over Tek-VISA layer is not initialized if in TekVISA Instrument manager the search criteria is turned-off, even if a valid instrument is connected in the network. It is necessary to turn ON the respective search criteria by opening the TekVISA Instrument manager.

TestStand Run time Engine Installation

Managing multiple versions of TestStand installed on the system.

TekExpress installs TestStand version 4.2.1 runtime engine. If you have other versions, ensure that the version shipped with TekExpress is active while working with TekExpress. You can do so by clicking Start > Programs > National Instruments > TestStand 4.2.1 > TestStand Version Selector.
