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;
Network tester Vega TS-11 is
designed for testing LoRaWAN
networks while them is
deploying and setting up

DDM - Downlink demodulation margin (hereinafter DM);
PER (packet error rate) –relation of the received packets number to the total

WORK SCREEN 1 –UPLINK AND DOWNLINK DEMODULATION MARGIN
First work screen appears just 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).

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.
‘Hourglass’ icon –automatic mode indicator is located in the upper right corner of the
screen. 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.
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).

WORK SCREEN 2 –FULL INFORMATION ABOUT THE NETWORK
Switching between screens is carried out by pressing ‘Left’and ‘Right’ buttons. During the
testing process, you can freely navigate between them to get more complete information about
the network. Work screen 2 allows you to get the follow information:
PER coefficient –percent of successful transmissions;
Number of visible gateways;
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;

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 /
transmitted packets.
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).
‘Network’ icon - has two states: joined / disconnected. Next to the icon, the network
capacity is displayed as a number of gateways that successfully received the latest packet from
the network tester.
Status line –the current transmission status is displayed in text form:
join TX –a request to join the network is performed;
join RX –reception of confirmation to a network connection request;
joined –the connection to the network was successful (the ‘Network’icon
changes its status);
link TX –‘Uplink’ request is performed;
link RX –reception of confirmation ‘Downlink’;
link OK –communication session was successful;
time-out –‘Downlink’ packet receiving window timeout expires;
error –communication session error.
‘Antenna’ icon –is located above the title bar and displays the moments of sending and
receiving packets as an animation.
Title bar –is located in the center of work screen. It is the list of displayed parameters. To
the left of the title bar there is transmitting information is displayed, to the right of the title bar
there is reception information.

The custom frequency plan is limited in the range of 860-960 MHz. The data rate (DR) of the
second receiving window (RX2) can take values from 0 to 5, where 0 corresponds to spread
factor 12 (SF12).
ADR –allows to on/off an automatic data rate set of the ‘Uplink’ packet and the first
receiving window also. ADR parameter have not influence on the data rate of the second
receiving window.
Data rate –sets data rate of the ‘Uplink’ packet and the first receiving window while ADR
parameter is switched off and can vary from 0 to 5. When ADR parameter is switch on the first
attempt to join the network will initiates with this data rate value.
Device sound –switch on/off the network tester sound. ON –all sound signals is on. OFF
–all sound signals is off.
Logotype –logotype displaying while device is switching on. ON –logotype and
firmware version are displayed, OFF –no logotype and firmware version are displayed, there is
work screen 1 appears at once.
Auto-off minute –set timeout of automatic network tester switch off. Timeout sets in
minutes from 1 to 60. The timeout is restarted each time for the specified period by pressing any
button on the device. If no device button is pressed, then after timeout expired the network
tester goes to sleep mode, to save the battery power.
The auto-off function is deactivated during the device operates in the automatic test mode.
Request period –set automatic test mode period. The period may be equal to any value
from 30 seconds to 24 hours accurate to a second. There is the follow display format –
hours:minuts:seconds. One pressing on the ‘Right’ button will increase the counter by one
second. If you press the ‘Right’button and hold it, the counter will start increase by 1 minute. If
you hold the button for more than 5 seconds, the minutes counter will accelerate to 5 minutes
at a time and so on. After the value 24:00:00, the value 00:00:30 appears again. The ‘Left’button
decreases the counter value in the same way.
