1 DESCRIPTION AND OPERATION
Tester sends a special signal to the LoRaWAN™ network (‘Uplink’ packet), in response to
which the tester received a confirmation (‘Downlink’ packet).
Tester represents various information about network:
▪«Uplink»frequency –frequency on which the request sent to the network (MHz);
▪«Downlink»frequency - frequency on which the confirmation sent from the
network (MHz);
▪SF (spread factor) - coefficient determining the data rate of «Uplink» and
«Downlink»signals;
▪Tester’s transmitter power (dBm);
▪Requests number;
▪RSSI (Received signal strength indicator) –«Downlink» signal power (dBm);

▪DDM - Downlink demodulation margin (hereinafter DM);
▪PER (packet error rate) –relation of the received packets number to the total
number of sending packets expressed as a percentage;
▪Number of visible gateways.
In addition, tester may represent information from navigation satellites:
▪number of visible GPS and GLONASS satellites;
▪LAT / LON –latitude / longitude –coordinates of tester;
▪UTC –current satellites time;
▪ALT –altitude;

WORK SCREEN 1 –UPLINK AND DOWNLINK DEMODULATION MARGIN
Work screen 2appears just after device switch on. Switching between screens carried out
by pressing ‘Left’and ‘Right’ buttons. During the testing process, you can freely navigate between
them to get more completely information about the network.
For the work screen 1 appearing, you can press ‘Left’ button after device switch on.
Herewith the data is not available on it. Work screen 1 allows you to get the follow information:
▪Number of visible gateways;
▪PER coefficient –percent of successful transmissions;
▪Margin demodulation diagrams and numerical values of UM and DM of the last
session.
Margin demodulation is the positive integer value displayed in dBm and indicating how much
received signal above the demodulation threshold. ‘0’ value means that the packet was received
on the bottom of demodulation (0 dBm), whereas, for example, ‘20’ value means that the packet
was received on 20 dBm above the demodulation threshold.

‘Gateway’ icon - displays the activity of the communication process as an animation.
Animation continues until the confirmation is accepted or the receiving window timeout expires.
Number of gateways - the number of gateways received the last packet from the network
tester successfully.
Percent of successful transmissions –PER (Packet error rate) coefficient is calculated as
the ratio of the number of confirmations received by the tester from the network to the total
number of requests, expressed as a percentage. It can vary from 0 (no one confirmation has come,
or PER is less than 1% and rounding up to integer) to 100% (the number of confirmations is equal
to the number of requests).
Battery charge –displays the current battery charge status. When the battery is critically
discharged, the icon becomes empty, flashes, and the tester emits a periodic beep. The
approximate remaining time of operation is not more than 5 minutes, it is necessary to charge the
battery.
The first time the ‘Up’button is pressed, the tester sends a request to the network to join
the network (hereinafter ‘join-request’), which is displayed on the UM (Uplink demodulation
margin) diagram as a shaded bar. If the tester is successfully connected to the network, a filled bar
appears in the DM diagram (Downlink demodulation margin).

Revision 02 - 08 October 2019
A shaded bar appears on the DM diagram if a failed attempt is made also. In total, the
network tester takes three attempts to join the network.
After successful joining the network, you can start testing the network. There are two ways:
manual and automatic. In the first case, the network tester sends an Uplink request to the network
each time the ‘Up’ button is pressed. In the automatic mode, the tester will send requests itself
with the period specified in settings, and also by pressing the ‘Up’button.

‘P’ icon –automatic mode indicator is located near the ‘Gateway’ icon. If it is, automatic
test mode is on, if not - off.
Diagrams DM and UM - the arrow indicates the direction of the radio signal propagation,
and the diagram shows the history of its change. The level of each bar on diagram shows the
demodulation margin of a particular packet. The latest (recent) radio communication is displayed
on the bar located next to the arrow. On the arrow is displayed the numerical value of the
demodulation margin in dBm of the latest radio communication. During the execution of new
communications, the diagram shifts to the right.
‘GPS’ icon - satellite positioning function indicator located in upper right screen side. If it is
satellite positioning function is on, if there is no –off.
If the radio communication has not passed or the data has not been received, for example,
an error occurred during reception or the confirmation window timeout expires, the shaded bar
is displayed (that bar type has no level and occupies the entire amplitude of the diagram).

▪Tester’s join status;
▪Number of packets transmitted by the tester - COUNT;
▪UM (demodulation margin), P(power), SF (spread factor) and FQ (frequency) of the
latest transmitted packet;
▪Receiving window number of the latest received confirmation - slot;
▪Number of packets received by the gateway - COUNT;
▪DM (demodulation margin), RSSI (signal level), SF (spread factor) and FQ (frequency)
of the latest received packet.
Unlike other screens, the work screen 2 displays information only about the last communication
session. The accumulated data here is the PER coefficient and the total number of received /
