Overview
The QAM Snare Snoop is designed with the
fulfillment technician in mind for troubleshooting
within the home or at the drop. It is a multi-
modulation format, multi-channel detector that is
extremely flexible for the user. It will operate in
QAM, Analog, Pilot/QAM, OFDM and Shielding Test
detector modes. The device does not provide the
ability to record drive-outs, and does not report
detected leaks to the QAM Snare server database.
However, when the Snoop Auto Detection profile is
configured, the Snoop Time and GPS coordinates are
captured at the server to log activity each time the
detector is activated.
When not being used, it is stored in its cradle, where
is receives power as well as the GPS from the roof
antenna which attaches to the cradle. It is designed
to remain powered while cradled such that it
establishes GPS lock and is always ready to be used
without wait time for the technician. When the
technician needs to use the detector, it is pulled
from the cradle and the technician can freely move
to the leak source. The Snoop is a Wi-Fi device that
requires Wi-Fi connectivity when used in the QAM
detector mode. When used in Analog detector,
Pilot/QAM detector, Shielding Test detector and
OFDM detector modes it does not require Wi-Fi
connectivity nor does it require GPS lock.
The Snoop Shielding Test detector mode is intended to be used in conjunction with
the QAM Snare Pilot Transmitter, to quickly troubleshoot locations in the home and
MDU’s where poor shielding effectiveness results in forward ingress issues related to
close proximity LTE transmitters. Others have referred to this testing technique as
‘Pressure Testing’.
The device contains no maps and provides the user with no feedback as to the
flagged leak location. If it is desired to utilize this product as a find and fix tool at leak
locations previously identified by other QAM Snare devices having drive-out capability,
6
as a time saver it is recommended to use the QAM Snare Web Client on a mobile device
to have visibility to the GPS calculated flagged leak location which provides an accurate
starting point for the final search. This process is much more effective than blindly
walking around, but marginally more time consuming as compared to the Navigator
Plus device which contain maps integrated within the device display.
Screen Navigation
Upon startup the user can either select Detector mode,
where the unit will function as a leakage detector – or the
user can select Settings, where various changes to the
operating parameters are made.
Screen navigation is performed with a simple three
button scheme. The left and right arrows move the
highlighted cursor to the desired item to be selected, and
the middle circular enter button is used to confirm the
selected menu item. The circular middle button also
functions as a power button and turns the unit on by
pressing and holding for two seconds.
Settings
The Settings button is used to select all the various
configuration options. To access this mode, use the left or
right arrow to highlight the Settings mode and press enter.
Settings related to the QAM Snare server and the Wi-Fi
profiles that the device attaches to MUST be configured
through the Q-browser software program.
7
General
The General settings button provides for access to several
miscellaneous configuration items which are detailed below.
Information
The Information selection item provide the user with
information on the Device ID (which by default is the MAC
address) and Technician ID that was assigned to the unit
through Q-browser. It provides information on the Firmware
revision, the QAM Snare Server name it is configured to
connect to, and the device MAC address. For security
reasons, the Wi-Fi configuration is not displayed – but this
information is available through the Q-browser.
Sound
The Sound button allows the user to turn the audio alarm
and button feedback on or off. Naviagate to Sound and
press enter, then use the right or left arrow to select on or
off, then press enter to confirm the selection. The threshold
setting for high and low leak alarms is configured in the Leak
alarms menu item, and the sound off setting configured here
will override the Leak alarm setting.
8
Auto start
The Auto Start/Stop setting allows the unit to turn on and
establish GPS lock automatically when power is applied, as
when the vehicle is started. It will NOT automatically enter
detector mode, as it is not intended to detect leaks while
cradled. This setting also controls an Auto Off counter
feature, which powers the device down when power is
disconnected, as the vehicle is turned off.
Auto Detect Profile
The Auto Detect Profile turns on and off the ability to
automatically switch between detection profile (Analog, QAM,
Pilot/QAM, and OFDM) based on GPS coordinates. Different
sections of the cable network can have different channel
lineups and can utilize different modulation format, or can
be in R-PHY node areas. Since the detection schema can be
different in different areas, the Auto Detection Profile feature provides a means to for
the detector to automatically switch to the correct detection profile without user
involvement. The QAM Snare Server communicates with the detector and based upon
its GPS location tells it which mode it should be in. Additionally, when Auto Detection
Profile is ON, and Wi-Fi & QS Server credentials have been entered, the Snoop will
connect to a selected server to send GPS Time and coordinates to the server. This is
used to log Snoop usage activity only, and no leakage data is recorded. “GPS SYNC” is
required when Auto Detect Profile is turned “ON”.
When Auto Detection Profile is ON, the main menu will indicate this by adding
“AUTO” to the detector menu option.

Standard
This allow to change the television standard between
NTSC, PAL B/G, and PAL D/K so the proper channel listing
can be selected. It is a one-time setup parameter.
Exit
Exit returns to the higher-level menu screen. Select and
press enter.
Connection
The connection menu item is used to select the QAM
Snare server and Wi-Fi devices the Snoop connects to.
Specifics related to these connections must be entered using
the Q-browser software program by connecting a PC to the
device through the USB port on the cradle. Multiple profiles
may be entered, and the connection setting allows the user to select from previously
entered profiles, but it will not allow profiles to be entered directly into the Snoop.
QS Server
The QAM Snare Server which the
device needs to connect to is
selected here. Press enter and the
profiles of servers previously
configured through the Q-browser
are displayed, with the server name
and IP address displayed. To select a different server press next server. If the required
server is not displayed it must be configured through the Q-browser. Multiple server
10
profiles would only be necessary for the technician that works in areas covering more
than one server.
For clarification, a typical QAM Snare installation will have multiple hubs connected
to one server that covers a broad area. One signal processor hardware device is
required in each hub, and the signal processors communicate with the QAM Snare
server when in QAM Detector mode. The server monitors the GPS location of each
connected field device and coordinates that each device receives signal samples
appropriate for the hub the field device is currently located. This setting has nothing
to do with signal processors as that is managed by the server – just multiple server
addresses.
Wi-Fi profile
The Snoop is a Wi-Fi enabled device that requires
connectivity to operate in QAM detector mode. Profiles that
were previously entered into the device through the Q-
browser are selected through this menu item. Multiple
profiles may be stored in device, and selected when desired.
Walk mode -vs-Truck mode
Other QAM Snare products such as the Navigator Plus utilize a Truck mode and
Walk mode concept for how the device operates when it is cradled and when it is used
by the technician moving around. Since the Snoop is designed to be used only while
moving around outside the vehicle, it inherently operates in Walk mode, as has no
Truck mode capability.
