MAKING MEASUREMENTS
NOTE: Interpreting the results provided by the Beacon Tester

requires some knowledge of beacon requirements. Using the self
test mode of the beacon may result in some measurements being
outside the required limits due to the lack of a warm-up period.

WARNING! DO NOT ACTIVATE ANY BEACON IN ITS NORMAL ACTIVATE MODE
UNLESS THE BEACON IS IN A SCREEN BOX (TSE100) OR A SCREEN ROOM.
DOING SO COULD RESULT IN A FALSE DISTRESS ALERT.

General:

All measurements will produce a Test Report in a PDF format, and a
data file in comma separated values (.csv) format for easily importing
into a spreadsheet for data parsing and saving.

Measurement results are stored in the BT200 device. Each
measurement will be saved in a folder with the same name as the
measurement filename. For example, a measurement with the filename
“Burst-1” is made on a beacon. When the measurement is completed,
the following is created:

<Burst-1> folder name
<images> folder contain graphic images
Burst-1.csv measurement data file
Burst-1.pdf PDF Test Report

When the Auto Increment feature is enabled in the Filename field, the
next measurement will be named Burst-2.

When the Receive Mode settings are set to Continuous Receive,
then each subsequent burst measurement data will be appended to the
stored data file (.csv file).

16

Connecting the Beacon:

There are 3 methods for receiving a signal from a beacon – using the
Internal Antenna, the Direct Connection mode, or the Screen Box
Connection mode.

Internal Antenna:

 select Internal Antenna from the Input Mode on the Home screen.
When a measurement is completed, the power level units will be shown

in %, with 100% being displayed when the tester is very close to the
antenna of the transmitting beacon.

Direct Connection:

 select Direct Connection from the Input Mode on the Home screen.
 attach the RF Interface Cable (p/n 130-024) to the RF IN connector

located on the rear of the BT200 device. Attach the beacon.
When a measurement is completed, the power level units will be shown

in dBm. This measurement is very accurate. If cable loss factors are
setup in the Settings > General > Cable Loss section, then these
factors are included in the power level measurements.

Screen Box Connection:

 select Screen Box Connection from the Input Mode on the Home
screen.

 attach a cable from the output of a Screen Box to the RF Interface
Cable (p/n 130-024) which is connected to the RF IN connector located
on the rear of the BT200 device.

17

Single Burst Measurement:

 activate the beacon under test.
 tap the Beacon Test button.

The following screen will appear and the timer will start.

BEACON TEST

button

18

 if the beacon is transmitting a 121.5 and/or 243 MHz homing signal,
the tester will produce the characteristic swept audio tone and indicate
on the display that channel has been received. These signals must be
received prior to the 406 MHz burst in order to be measured.

 once a 406 MHz burst is received, the measurement is complete and
the results are displayed.

Continuous Measurement:

 when making a measurement in Continuous mode, once a
measurement is complete, the device will return to the Measuring
screen and continue waiting for another measurement. This will
continue until the user taps Cancel, at which time the measurement will
end.

SOFTWARE UPDATES

Software updates are available free of charge on the Google Play Store
or on the WS Technologies Inc. website:

www.wst.ca/BT200software.html

You are encouraged to keep your Beacon Tester software up to date
by downloading and installing the most current software revision.

BEACON TESTER MODEL UPGRADING

All models can be remotely upgraded as desired. Please contact WS
Technologies Inc. at [e-mail] for upgrade costs and procedures.

USING THE TSE100 SCREEN BOX

The TSE100 Screen Box will allow testing of the beacon in normal
activate mode without the risk of being detected by a satellite (causing
a false alert). If the beacon being tested has an internal GPS receiver,
the TSE100 will allow you to verify the GPS reception and ensure
proper encoding of location data onto the 406 MHz transmission.

Both the beacon and the BT200 are placed into the TSE100 Screen
Box. The viewing window and the screened gloves allow you to control
both the beacon and the Beacon Tester. If connecting the beacon and
tester directly, use Direct Connection mode. Use Internal Antenna
mode if the beacon is transmitting through its antenna.

For other Screen Boxes that have a sniffer antenna and an RF out
connector, use the Screen Box Connection mode.

32

FREQUENTLY ASKED QUESTIONS
Why is my battery depleting so quickly?

In order to save battery power, turn off WiFi and keep the screen
brightness to a minimum whenever possible. Do not turn off Bluetooth
as this is used internally to the BT200.

My Beacon Tester won’t receive either 406 MHz or 121.5 MHz.

Ensure that the proper Input mode is selected. If you are receiving a
beacon self test transmission through its antenna, then select Internal

Antenna. If you are connected directly to the beacon then select Direct
Connection.

The Bluetooth on my device is not functioning.

Some functions on the device, such as Bluetooth, are functions
dedicated to the operation of the Beacon Tester. The NFC is also not
functional.

My GPS coordinates are being displayed in degrees/decimal

minutes (dd° mm.mm’). I prefer degrees/minutes/seconds
(dd° mm’ ss”). How do I change this?

Tap Settings > General > Location Coordinate Format. Select the
desired format.

When I launch the Beacon Tester app, after it is Initialized the
spinning timer goes for a long time.

The length of time the timer continues depends on the number of
measurement files in the Measurements folder. If you reduce the
number of files the app will launch quicker.

How do I update the Beacon Tester software?

Use the Google Play Store to install the Beacon Tester app, or go to
the WS Technologies Inc. website at ww.wst.ca/BT200software.html
and follow the instructions on updating the application software.

When I activate the beacon in self test mode, the measurements
produce questionable results. Is there a problem with the beacon?

In order to meet all of the Cospas-Sarsat requirements, a beacon is
allowed a 15 minute warm-up period. When testing a beacon in self
test, there is no warm-up period, hence some measurements may be
somewhat skewed.
Also, in self-test, the 121.5 homing transmission may be different
depending on the particular beacon. Some beacons transmit a short

33

modulated signal, some beacons transmit a shorter unmodulated signal
and some beacons transmit no signal. The Beacon Tester may indicate

“unable to measure details” or “unmodulated carrier” depending on the

beacon characteristics.

I am testing an ELT with separate 121.5 and 406 output
connectors. What do I do to get the results printed on one Test
Report?

Connect to the 121.5 transmitter first, then start the test. Once the
Beacon Tester gives the indication that the 121.5 signal has been
received, switch the cable to the 406 transmitter without stopping the
test. Once the 406 burst is received on the Beacon Tester, the
measurement will be complete.

Is the characteristic swept tone audio that I hear when the Beacon
Tester receives a 121.5 MHz signal the actual demodulated audio
from the beacon?

No, the swept tone audio is just an audio file played when the tester
has received a 121 MHz signal.

The beacon I want to measure has offset training frequencies on

121.5 and 243 MHz. How do I setup the Beacon Tester to receive
these training frequencies?

Measuring Training Frequencies is not currently available on the
BT200. It will be available in a future software release.
