The Frontline hardware interfaces with your computer that is running our robust software engine called the
ComProbe Protocol Analysis System or Frontline software. Whether you are sniffing the air or connecting directly
to the chip Frontline analyzers use the same powerful Frontline software to help you test, troubleshoot, and
debug communications faster.
Frontline software is an easy to use and powerful protocol analysis platform. Simply use the appropriate Frontline
hardware or write your own proprietary code to pump communication streams directly into the Frontline
software where they are decoded, decrypted, and analyzed. Within the Frontline software you see packets,
frames, events, coexistence, binary, hex, radix, statistics, errors, and much more.
This manual is a user guide that takes you from connecting and setting up the hardware through all of the
Frontline software functions for your Frontline hardware. Should you have any questions contact the Frontline
Technical Support Team.

5. It may take as long as thirty seconds for Windows to recognize that the Frontline 802.11 hardware is
connected to the PC. The Activity light on the Frontline 802.11 front panel (Figure 2.1 will blink during this
period, when the light is steady, the Frontline 802.11 hardware is ready to communicate with the
Frontline software.
2.1.3 Setting Up for ProbeSync™
The Frontline 802.11 hardware has ProbeSync™ which allows for synchronization of Frontline hardware clocks
and timestamping. One Frontline device will act as the master device by providing the clock to the slave device
receiving the clock. Do not confuse "master" and "slave" with the Bluetooth device master and slave relationships.
Refer to the following tables.

10 Frontline 802.11 Hardware & Software User Manual
Chapter 2 Getting Started TELEDYNE LECROY
Figure 2.8 - Control Window
Because the Control window can get lost behind other windows, every window has a Home icon that brings
the Control window back to the front. Just click on the Home icon to restore the Control window.
When running the Capture File Viewer, the Control window toolbar and menus contain only those selections
needed to open a capture file and display the About box. Once a capture file is opened, the analyzer limits Control
window functions to those that are useful for analyzing data contained in the current file. Because you cannot
capture data while using Capture File Viewer, data capture functions are unavailable. For example, when
viewing Ethernet data, the Signal Display is not available. The title bar of the Control window displays the name of
the currently open file. The status line (below the toolbar) shows the configuration settings that were in use when
the capture file was created.
2.3.1 Control Window Toolbar
Toolbar icon displays vary according to operating mode and/or data displayed. Available icons appear in color,
while unavailable icons are not visible. Grayed-out icons are available for the Frontline hardware and software
configuration in use but are not active until certain operating conditions occur. All toolbar icons have
corresponding menu bar items or options.

also provides such things as name of the network card, address information, ports in use, etc.
2.3.3 Status Information on the Control Window
The Status bar located just below the Configuration bar on the Control window provides a quick look at current
activity in the analyzer.
l Capture Status displays Not Active, Paused or Running and refers to the state of data capture.
o
Not Active means that the analyzer is not currently capturing data.
o
Paused means that data capture has been suspended.
o
Running means that the analyzer is actively capturing data.
l
% Used
The next item shows how much of the buffer or capture file has been filled. For example, if you are
capturing to disk and have specified a 200 Kb capture file, the bar graph tells you how much of the capture
file has been used. When the graph reaches 100%, capture either stops or the file begins to overwrite the
oldest data, depending on the choices you made in the System Settings.
l
Utilization/Events
The second half of the status bar gives the current utilization and total number of events seen on the
network. This is the total number of events monitored, not the total number of events captured. The
12 Frontline 802.11 Hardware & Software User Manual
Chapter 2 Getting Started TELEDYNE LECROY
analyzer is always monitoring the circuit, even when data is not actively being captured. These graphs
allow you to keep an eye on what is happening on the circuit, without requiring you to capture data.
2.3.4 Frame Information on the Control Window
Frame Decoder information is located just below the Status bar on the Control window. It displays two pieces of
information.
l Frame Decoder (233 fps) displays the number of frames per second being decoded. You can toggle this
display on/off with Ctrl-D, but it is available only during a live capture.
l #132911 displays the total frames decoded.
l 100% displays the percentage of buffer space used.
2.3.5 Control Window Menus
