2.5.0

1-May-2012

Add HF STANAG-4285 into “Configuration W-CODE  Decoder
Bitstream Type”

Add “Convolutional Encoder”, “Generate Pseudo-Noise” functions
Add various functionalities to analyse STANAG4285 bitstream

Requirements

.NET Framework version 2.0 must be installed. The framework is included in the setup and is installed if
missing on the system.

Limitations

In this version of BitView, the maximum number of bits that can be imported is limited to one million bits.

Bear in mind that some formatting functions such as bit highlighting consume a lot of CPU power and may
require considerable time to complete, especially on less powerful systems. Reducing the number of
imported bits will speed up the application.

Bit streams are imported completely raw and unsynchronized, i.e., BitView will not recognize additional
information like confidence levels from soft-decision decoders or symbol boundaries for m-ary modulation
types. Any such information must be removed using the BitView toolbox functions.

Installation

W-BV Software Installation

To install the application, you can use the Wavecom installation DVD, click the corresponding button.

W-BV Hardware Installation

Apart from a Windows PC and software protection hardware, no additional hardware is required to operate
the software.

CmStick

Software protection hardware has to be connected to the computer. The hardware device used for the
software protection is called the CmStick and is available as:

 A small USB device
 A PC Card (CmCard/M, Cardbus, 32 Bit)
 An Express Card|34 (CmCard/E)

The W-BV application will not start if the appropriate and valid licenses are not found on a CmStick
connected to the system.

After the installation of the software on the computer, the CmStick icon will be displayed in the tray
icon area.

Note: when a CmStick is plugged into an USB socket of a LCD monitor, the CmStick will no longer be
detected by the software protection server if the monitor is switched off. Hence a running application
relying on the licenses stored on such a CmStick will stop working or disable its features.

W-BV Licensing

On request, we can generate different license models, even complex ones

 Single user license
 Evaluation licenses (number of starts, limited usage period, activation and/or expiration time)
 Modular licenses (activation of additional functions)
 Also licenses from other software manufacturers can be stored on a CmStick containing WAVECOM

licenses

W-BV Software Options

Additional functions or services may be licensed to work with your tool, e.g.:

Getting Started

Program Start

Starting the program will introduce a license check procedure.

BitView Manual V2.5.00 WAVECOM W-BV Getting Started  11

If a valid license key was not found, the following message appears on the screen.

If a valid license key was found the application is started. The Toolbox, which contains the function
library, is displayed and enables the user to import a bit stream from a selection of different sources.

Alternatively, using the New button from the Toolbar, an empty document window is opened which
allows the user to manually create a bit stream, or copy and paste a bit stream from another source.

Another option, using the Open button from the Toolbar, allows a previously saved Analysis Set (stored
in an .XML file) to be opened (see later in this manual for details).

Bit Stream Import

An imported bit stream is shown in a document window, and the Properties and History Explorer
windows are opened. In general, the Properties window displays all the properties of a selected function,
and the History Explorer window shows the dependencies of all functions in a tree view.

12  Getting Started BitView Manual V2.5.00 WAVECOM W-BV

Menu

Bit Stream Processing

An imported bit stream may be processed using any of the functions found in the library.

BitView Manual V2.5.00 WAVECOM W-BV Menu  13

The position of the cursor (line, column and index) in the bit display is continuously indicated in the
bottom line of the application window. To select a number of bits, press and hold the left mouse button.
The selected bits are marked in blue and the number of selected bits, and the decimal values of these bits
interpreted as big-endian or little-endian values are displayed in the bottom line. Left-clicking anywhere in
the display window will cancel the selection.

The processed bit stream is shown in a new document window. All document windows are shown as
tabbed windows.

Analysis Sets

Functions and data may be combined to form a so-called Analysis Set, which contains an imported bit
stream and the configured functions applied to the bit stream. The user may define and create different
analysis paths, as may be seen in the History Explorer. The imported bit stream is processed according
to the configuration settings of the selected functions.

Using the Save button in the toolbar, Analysis Sets may be saved in an XML file. Using the Open button,
an Analysis Set may be reloaded at any time.

14  Menu BitView Manual V2.5.00 WAVECOM W-BV

Reports

Using the Report button a complete Analysis Set may be generated and saved as a text file or a XML
file.

Properties Window

The parameters in the Properties window are grouped into different categories providing the operator
with information about actual parameter settings and - more important - allowing the operator to
configure each function and to add comments.

Detailed information about the selected parameter is displayed in the text area at the foot of the
Properties window.

In the Counter category information on the recorded bit stream, i.e., Bit count, number of logical Ones
and number of logical Zeros is found.

The Information category contains information on the selected source or analysis set, i.e., Analysis
name, Comments (user input possible), File name (information only) and Function name (information
only). Clicking the function name displays a brief description of the function.

The History Explorer window provides a quick overview of the current analyzing process. It allows the
operator to try out different function paths with different parameter settings and enables instant
comparison of the results of these trials.

Functions may be re-arranged and deleted using the mouse pointer (drag-and-drop with left mouse button
pressed and held) in combination with the modifier buttons (CTRL, ALT, SHIFT) or the mouse right-click
menu.

When one of the modifier buttons is pressed while dragging, detailed information is displayed on top of the
window.

If the History Explorer window has been hidden a list of functions applied is still available by clicking the
arrow button in the top right corner of a document window.

BitView Manual V2.5.00 WAVECOM W-BV Menu  17

Toolbox Window

The Toolbox menu is divided into libraries, and each library contains one or more functions.

Note: The Custom Library is not visible unless a custom function has been added. The Analysis Tools
are not added to the History Explorer tree and are not persistently stored.

Preferences

The Preferences dialog box may be selected from the Setup menu.

Substitution symbols for logical zero and logical one may be directly edited or selected using the
appropriate Symbol button.

If Automatically update all data on a parameter change is ticked, all functions are automatically
recalculated when the operator changes a parameter. Uncheck the tick box if this behavior is not
desirable, and use the Recalc button in case a recalculation is necessary.

If Hide document on close is ticked, a document is hidden when closed, but remains in the History
Explorer. Clicking the function associated with the document in the History Explorer will make the
document visible again.

To remove the function completely, select the appropriate function in the History Explorer and press the
Delete key on your keyboard.

If this option is not checked, documents are completely removed when closed. Closing the root document
will close and remove all other functions and their associated documents.

18  Menu BitView Manual V2.5.00 WAVECOM W-BV

If Graphic/Hex display changes in all documents option is selected, all the documents will have the
same display settings, i.e., if the display is changed from graphic to hex in one document, and all other
documents will change their display type as well.

Layout Settings

At run time, the user can drag and drop all windows to re-arrange them according to the preferred layout
when not in auto-hide mode (map pin icon on window top line must be in vertical position). In the
selected window press and hold the left mouse button and drag the window to the position you want it be
in or just double-click the window and it will detach itself.

In addition the Parameters, History Explorer and Toolbox windows use auto-hide functionality. To
activate auto-hide for a window, click the map pin icon on the upper window line. The icon will change
from vertical to horizontal position.

The window is now hidden and a tab with its name appears on the side of the application window. To
make the window appear, move the cursor to the tab. To hide the window again, double-click on the
window.

To restore the application default layout, in the menu bar click View > Default Layout.

BitView Manual V2.5.00 WAVECOM W-BV Menu  19

Use View > Default Layout to use or restore the default layout of the windows.

More than one Analysis Set may be active at a time. Using the Window menu allows the user to show or
hide these Analysis Sets.

The layout and display settings can be configured from the upper part of the Properties window.

20  Menu BitView Manual V2.5.00 WAVECOM W-BV

Using the Bit & Text Display Configuration category in the Properties window enables the operator to
use different display format options listed below.

Word Wrap

Checking the Word Wrap Enabled tick box enables word wrapping in the bit and text document.

Bits per line

This parameter allows displaying a specific number of bits per line. Choose the Bits per line radio button
under Format Options to enable this feature.

Bit Field Alignment

Whenever the specified bit pattern is found in the bit stream, a new line is started, i.e., a line break is
inserted. Choose the Bitfield aligned radio button under Format Options to enable this feature.

Highlighting

The bit stream is searched for a specific bit pattern and when found the pattern is marked. A maximum of
four different search patterns are possible. Check the Highlighting check box to enable this feature and
enter the search patterns in the appropriate text fields.

BitView Manual V2.5.00 WAVECOM W-BV Menu  21

Display options

In addition to the document window(s), two additional views of the bit stream being analyzed are
available at the bottom of the document window(s): one is a graphical display and the other one a
hexadecimal display.

Graphic Display

A graphic display is associated with the bit stream and may be selected from the top of the Properties
window clicking the Show Graphics bit view icon.

The vertical size of the graphic display can be changed by dragging its top border.

The Layout category let you change the appearance of the graphic display.

In the Graphic Display Configuration category the number of bits per line can be set. This feature can
be used to find periodic bit patterns in the bit stream by changing the number of bits per line until a
repeating bit pattern is visible. It is much easier to find those patterns using the graphic display than to
use the hex display.

The arrow buttons on top of the Properties window are designed to move the active selection in the
graphic display. The selected bits are displayed as Raw Bits in the bottom of the graphic display.

When the cursor is placed in the graphic display, the cursor changes into a cross hair and a context
window indicates the position of the cursor (offset, row and column). Holding the right mouse button
allows the user to zoom in on the selected area. Right-clicking will make an Unzoom button appear. Use
this button to un-zoom the selected area.

It is possible to zoom into the graphic display. Hold the left mouse button down and select the area that is
to be expanded. A right click on the graphic display shows the context menu for un-zooming the view.

Hex Display

A hex display may be selected by pressing the Show Hex view button on top of the Properties window.
This display option offers a standard hex dump layout consisting of an offset in hexadecimal notation,
hexadecimal characters separated by a space and finally the data in ASCII characters.

The interpretation of 8-bit frames can be toggled between Little and Big endian in Hex View
Configuration, Endianness, i.e., “00101100” is displayed as 0x34 when interpreted as little endian and
as 0x2c when interpreted as big endian.

Printer Dialog

22  Menu BitView Manual V2.5.00 WAVECOM W-BV

The printer dialog is used for print preview and the printer settings. Use it by clicking the Print button or
by selecting the menu entry File > Print. All layout settings, i.e., highlighting, alignment or bits per line,
are supported.

Function Library

Common Functions

Auto-Calculation

To test a hypothesis regarding the properties of a bit stream, the operator may wish to test a property
within a specific range of values. This task can either be conducted by changing the parameter value
manually and then checking the outputs one by one or it can be performed automatically. That is where
Auto-Calculation comes into play.

A right click on the parameter name (not the value) in the parameters window opens a context menu.
Click Reset to change parameters to their default values or click AutoCalc Setup to open the Auto-
Calculation window:

Start and stop values for the selected parameter must be chosen using the Value range starts at and
Value range stops at parameters. The auto-calculation function then needs to be told which function will

monitor the calculation output by use the function drop-down menu of the Monitor function name
parameter – the function MUST be lower in the function tree as displayed in the History window.
Automatic calculation can now be started by clicking the Start button.

The result of the auto-calculation is displayed in the left side of the Auto-Calculation window. Edit >
