is beyond 50M.
Importing from RSA 3k: RFXpress looses connection with RSA 3k at times while
acquiring over 40M data.
Preview plot in environment: The environment preview plots will display preview
only for first 15 signals only due to memory limitations.
Setup restore: For environment plug-in setup restore does not restore signal
duration for Generic and UWB signal if duration is different from default duration.
Generic Signal Hopping: In multicarrier signal if hopping is enabled for 2nd
carrier the settings gets lost on moving focus to another carrier.

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 should be installed for RFXpress to execute.
- TekVISA version 3.3.4.6 is needed to run Calibration and Import waveform from
Oscilloscopes.
- RFXpress would communicate with AWG software to transfer the waveforms after
compiling. This functionality will work only if RFXpress is invoked after AWG
software has come up.

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.
