read-out may be also be carried out by one of the three available communication links: USB, OR-1
radio receiver, and GSM modem.
The device is provided with a built-in GSM modem (UMTS standard) and an antenna. This
solution provides it with almost unrestricted access to the analyzer from any chosen global location
with available GSM network. On the left side of its housing the analyzer has a SIM card, which is
required for data transmission via GSM networks.
Another advantage of the device is a built-in GPS receiver with antenna, making the analyzer
fully compliant with the requirements of IEC 61000-4-30 Class A, without the need of installing ad-
ditional accessories. The GPS receiver ensures the synchronization with UTC (Universal Time
Clock), and provides measurement accuracy of tens of nanoseconds. GPS receivers may receive
satellite signals in the open air; therefore synchronization with a built-in antenna is possible only
outside of buildings. When the analyzer is used indoors, in order to ensure the availability of the
GPS signal, the device should be connected to an external GPS antenna (cable length: 10m) lo-
cated outside the building. External antenna is an additional accessory.
Recorded parameters are divided into groups that may be independently turned on/off for re-
cording purposes and this solution facilitates the rational management of the space on the memory
card. Parameters that are not recorded, leave more memory space for further measurements.
The analyzer has an internal power supply adapter operating in a wide input voltage range
90…760 V AC (127…760 V DC), which is provided with independent cables terminated with banana
plugs.
An important feature of the device is its ability to operate in harsh weather conditions - the
analyzer may be installed directly on electric poles. The ingress protection class of the analyzer is
IP 65, and operating temperature ranges from -20°C to +55°C.
Uninterrupted operation of the device (in case of power failure) is ensured by an internal re-
chargeable lithium-ion battery.
The user interface includes a color 3.5" LCD display with a resolution of 320x240 pixels and a
keypad with four buttons.
The full potential of the device may be released by using dedicated PC software "Sonel Analysis
2".
The analyzer may communicate with a PC in a 3 different ways:
via USB connection with a transmission speed up to 921.6 kbit/s; available data reading from
a memory card with a speed of a few MB/s,
via radio interface - using OR-1 receiver with a transmission rate of 57.6 kbit/s (range limited
to approx. 5 m),
via GSM connection using the Internet.
In order to use the first mode of wireless communication, OR-1 receiver must be connected to
a PC using its USB port. Communication in this mode is slower, therefore we recommend it to view
current (live) parameters of the measured network and to configure and control the analyzer. It is
not recommended to read a large amount of data stored on the memory card via a radio link, due
to the slower data transmission.
GSM network transmission requires an active user's SIM card to be inserted into the slot of
the analyzer. The card should have the service of data transmission activated and a static IP num-
ber. A PC connected to the analyzer, must have the Internet access.
