Using an Excel Template to Enter Dynamic Fading Settings

Using an Excel Spreadsheet Template for Dynamic Fading Setup

A Microsoft Excel spreadsheet template is provided to create the dynamic fading scenario file. The Agilent Dynamic Fading Template can be found at the following places:

On the PXB Desktop

In the C:\<Program Files for Win XP><Program Files (x86) for Win 7>\Agilent\PXB\Infrastructure\Applications\Fading directory

On the internet at http://www.agilent.com/find/PXB under the Technical Support tab

To use the Excel template to enter dynamic fading parameters, copy it to a PC that has an installed Microsoft Excel application.

The template provides a Dynamic Fading Setup Wizard that steps you through creating a spreadsheet with the correct number of paths and parameters that you want to define for each state in your dynamic fading scenario. The wizard can also be used to open a previously-saved dynamic fading file for review or editing.

Using the customized spreadsheet, you can then populate it with just the dynamic fading settings you need to test your waveform in changing environments.

When the waveform you are playing reaches the end of the dynamic fading settings in the spreadsheet, it loops back to the start and re-uses the dynamic fading settings in the spreadsheet again until the simulation is stopped. There is no limit to the number of times this looping will occur.

Using the Dynamic Fading Setup Wizard

Copy the Excel template to a PC containing a Microsoft Excel application. (The PXB does not provide this application.)

Open the Excel template on the PC.

You will need to enable macros to activate the Setup Wizard. In older versions of Excel, an initial dialog box appears to enable macros; later versions require that you enable macros under Security or Trust settings.

Refer to the Microsoft Excel help if you need assistance.

Use the Dynamic Fading Setup Wizard to:

Closed Create a new dynamic fading scenario file

Select the Create a new dynamic fading scenario file. selection in the wizard then click Next.
Select the configuration that is being used with this dynamic fading scenario in Configuration drop-down list box that is displayed then click Next.

Selecting the configuration provides the appropriate number of fader tabs (one tab for each fader used in the configuration) at the bottom of the dynamic fading spreadsheet.

Select the number of paths and the desired parameters (Loss, Delay, and UE Speed) that you want to configure for dynamic fading.

Click Finish to configure and display the Excel spreadsheet template based on your wizard selections. The wizard is also closed.
In the Excel spreadsheet template, enter the dynamic fading values for the paths and fader channels as displayed in the spreadsheet as well as the carrier frequency.

The entered carrier frequency is used to validate the dwell time and UE speed entries before exporting the settings to a file. Slower UE speeds require longer dwell times, so in some cases, the actual dwell time may be longer than requested. An error message alerts you if there is a conflict that must be resolved before the file can be successfully exported.
Click Export to File in the upper left corner of the spreadsheet. If error messages are displayed, they must be resolved before the file can be successfully exported.
When the entered parameters are validated, the Save Dynamic Fading Setup As dialog box appears. Enter a name for the file in the required comma separated values file format (*.csv) and save it to a location of your choice.

Closed Open an existing dynamic fading scenario file for editing

Select the Open an existing dynamic fading scenario file. selection in the wizard then click Next.
Use the Browse button to locate and select the existing dynamic fading scenario file for review or editing.

Click Next if you want to make changes to your fading scenario.

Note: If you want to change the number of paths, it is best to configure a new spreadsheet, and copy/paste the parameters that you wish to keep.

Click Finish to close the wizard and display the selected spreadsheet.
In the spreadsheet, enter the values for the parameters for all paths and fader channels as well as the carrier frequency.

The entered carrier frequency is used to validate the dwell time and UE speed entries before exporting the settings to a file.
Click Export to File in the upper left corner of the spreadsheet. If an error message is displayed, it must be resolved before the file can be successfully exported.
When the entered parameters are validated, the Save Dynamic Fading Setup As dialog box appears. Enter a name for the file in the required comma separated values file format (*.csv) and save it to a location where it can be selected in the Download Panel of the PXB user interface.
