gives a lot of additional information on the system. In this mode, the device
is trying to register in the network of the selected operator. This function is
similar to service monitor mode of cellular phones, but data displayed in a
more convenient form and table. Some columns of table can be set hidden
in menu settings.
V. Measuring of isolation (insertion loss, attenuation).
This function finds a free frequency channel at the INPUT connector and
then measures the level of the own signal generated at the OUTPUT
connector. This allows to measure attenuation from 0 dB to more than 110
dB, which is enough to determine the level of isolation between donor and
service antennas for repeaters. Use an external directional coupler if
required to check RF matching (VSWR) of cable or other passive
components (antennas, splitters, combiners, etc.). It will be difference
(matching value) between forwarded and reflected levels at the coupling
connector. Bigger difference means better matching. Preferably, matching
value is higher than 10 dB, i.e. ratio VSWR < 2.
VI. Measuring of the signal quality.
This mode displays the level of the received signal in time by a diagram
during a call to an answering machine phone number. While the
connection is set, the Base Station measures the level of errors (BER) and
sends it to device to display. Upon expiration of the answering machine
time and drop call, the device performs redial. Enter a free of charge
phone numbers of answering machines for all installed SIM-cards in
software settings.
Caution! Please do not use phone numbers where people operated!
Main features of Windows based software.
The device is compatible with Window based PC via USB cable or Wi-Fi
connection. Software for PCs and laptops is a bit more functional, because of
there are more system resources and a “mouse”.
For Wi-Fi operation, first activate the Wi-Fi on the PC and then switch
on the device. Start searching of Wi-Fi access point on the PC. Select
CELLMETER in the list and connect to this network (Note: this network has
no Internet connection). Launch Cell Meter software and it will detect
device automatically. The device will indicate data communication by
frequent blinking of blue LED.
