Pre-requisite:

- Microsoft .NET 3.5 SP1 runtime framework is required for RFXpress to execute.
- Matlab Runtime 7.9 is required for RFXpress to execute.
- AWG software is required for RFXpress to execute.
- TekVISA version 3.3.4.6 is needed to run Calibration and Import waveform from Oscilloscopes.

Running RFXpress on Windows Vista
In Windows Vista, you must always run RFXpress with Administrator privileges. To do so, right-click either on the
RFXpress desktop shortcut or on the RFXpress application from
Windows Start menu >All Programs > Tektronix RFXpress and select Run as Administrator from the shortcut menu.

Installation Notes

You need to have administrator privileges to install Tektronix RFXpress software in your system. The Installation
program displays a warning message if you do not have administrator privileges. If you proceed by ignoring this warning,
the application may not install properly.

If you have not installed the required version of TekVisa RFXpress installation program will detect and prompt you to
install them.

If you want to reinstall your Tektronix RFXpress application software, you must first remove the existing software.
You can uninstall the software by going to Control Panel > Add Remove Programs and selecting Tektronix RFXpress.

If a failure occurs at any point during the installation of Tektronix RFXpress, the installer will not perform a
complete uninstall. For this reason, it is important not to pre-maturely close the installer application by clicking
on its close box in the upper-right corner of the background window; the installer will automatically close the
background window.

For details regarding the installation and use of RFXpress software, refer to the RFXpress Installation Manual.pdf file.

Viewing Sample Files

The installation program will copy several RFXpress sample files onto the target folder. You can open this folder
through the shortcut menu Target folder\Samples.

Under this folder there will be two sub folders namely Setup and Waveforms. The setup folder contains a few sample
setup files for Generic signal and Wi-Media. The Waveforms folder contains a few sample waveform files from AWG, RTSA
and Oscilloscope that can be opened in the RFXpress Application.
