SNYPER-3G Spectrum Overview
»liveSCAN directional antenna kit
Optional Accessories

The SNYPER-3G Spectrum is a high performance cellular signal and network analyser
for all 2G and 3G networks, with a host of important features for the busy engineer
and installer.
The SNYPER-3G Spectrum can perform a number of different functions to determine
optimum antenna placement and direction, performance of existing installations of
network operator. As an example, the SNYPER-3G Spectrum can determine the
strength of a particular network and the optimum direction of the antenna using the
liveSCAN feature.
The SNYPER-3G Spectrum has been designed to be as logical as possible, with a
simple to use menu and operation system. Provided with a large high contrast LCD
display, the SNYPER-3G Spectrum enures all the information is clearly visible, and
allows the presentation of considerable data at the same time.
The liveSCAN high performance directional antenna kits (sold seperately) has been
specically designed to complement the SNYPER-3G Spectrum when performing live
scans.

*The SNYPER-3G Spectrum SIM slot located in the enclosure base is used for enhanced network
services. A SIM is only required when performing a liveSCAN on a specic network operator. The SIM
has to be active, but it will not use any data during the liveSCAN survey as it is only required for network
functionality.

Powering the SNYPER-3G Spectrum
»The SNYPER-3G Spectrum needs to be charged using the mains adaptor for 6 -
8 hours before initial use. The SNYPER-3G Spectrum does not need a SIM card
to perform network and signal tests.
»Ensure the antenna is screwed rmly into place on the SNYPER-3G Spectrum
and isn’t loose.
»To power up the SNYPER-3G Spectrum press the ON/OFF button. A welcome
screen will be displayed briey (as shown below in gure 3) before the main

Charging and battery status bar:
During charging, the number of bars will increase and turn from red, to yellow, to
green. The charge status LED will be red.
A full line of green bars indicates that the unit is fully charged.
During use, the number of bars will decrease and turn from green, to yellow, to red.
Recharging is recommended once red bars are displayed on the SNYPER-3G
Spectrum battery status bar.
If the SNYPER-3G Spectrum drops below allowable low battery usage the unit will
switch off and charging will be required. At power on, if the battery is below allowable
low battery usage a low battery indicator will be displayed as shown below in gure 5.
NOTE - During low power charge the SNYPER-3G Spectrum will display the battery
screen (as shown below in gure 6) until the SNYPER-3G Spectrum has enough
power to be used.
Approximately 4 - 6 hours are needed to fully charge the unit using the default
fast charging mode. The SNYPER-3G Spectrum battery provides up to 15 hours
continuous liveSCAN use and up to 4 months standby mode.

Performing a liveSCAN*
*See the ‘liveSCAN Antenna - Quick Start Guide’ for a more detailed guide on using
and performing a liveSCAN.
NOTE: This operation requires an active SIM card to be inserted in the SNYPER-3G
Spectrum. Insert SIM as shown below in gure 18. The SIM needs to be fully pushed
inside the case using a screwdriver until a click is heard.
Any SIM card can be used as the liveSCAN will be performed for all networks,
regardless of the SIM card inserted.
