WST STB100 AIS Testing

STB100 BEACON TEST BENCH

General Overview

The STB100 Beacon Test Bench is becoming known as The Standard in beacon testing equipment worldwide. No other test equipment provides this level of detailed, accurate, and reliable measurements for both Cospas-Sarsat approved emergency beacons and AIS Transceivers (new).

The STB100 Beacon Test Bench is the perfect tester for shore-based maintenance facilities, avionics test facilities, beacon manufacturers, beacon developers, and IMO radio surveyors.

STB100 Beacon Test Bench

The STB100 measures all 406 MHz, 121.5 MHz, and 243 MHz emergency beacons, including AIS EPIRBs (new), 406 MHz frequency stability, and AIS Transceivers (new).

The STB100 also has very accurate DC current and voltage measuring allowing for characterization of power supplied to a beacon, as well as measuring leakage current down to 200nA.

The user friendly STB100 software is included free with the purchase of your STB100 unit and can be downloaded directly from our website. Alternately, advanced users can use the optional API command set to customize their own User Interface.

My STB100 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 Antenna. If you are connected directly to the beacon then select Direct Connection.

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 modulated signal, some beacons transmit a shorter unmodulated signal, and some beacons transmit no signal.

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?

The WST accessory 850-CMB102 is a low loss, 121.5/406 signal combiner. It can be used to combine the separate outputs from the ELT. Alternatively, you can complete the measurement in two steps: first, connect to the 121.5 transmitter, then start the test. Once the STB100 gives the indication that the 121.5 signal has been received, then switch the cable to the 406 transmitter without stopping the test. Once the 406 burst is received on the STB100, the measurement will be complete.

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 easy. Go to the Setup > VHF Training Frequencies and select the training frequencies you are using.
