Owner's manual

Airmar Air Transducers T1 Development Kit is a versatile tool for designing ultrasonic systems. It allows the user to quickly and easily transmit and receive echoes, making it ideal for a variety of applications, including:

  • Use with Airmar's Ultrasonic Transducers
  • Aid in designing ultrasonic systems
  • Allow the designer to quickly and easily transmit and receive echoes

The T1 Development Kit features jumper selectable pulse width and frequency for optimal interfacing. The transmit pulse is amplified to 200 - 500 Vpp via a power MOSFET and transformer. Received echoes can be viewed at X1, X10, X100, or X1000 amplification.

Set Up
J1—Set the jumper at the position appropriate for the
model being tested (see Table 1 and Figure 1). This selects
the initial value for the pulse rate.
J2—Set the jumper at the position appropriate for the model
being tested. This selects the initial value for frequency.
J8—Set the jumper to the proper voltage range for the
model being tested.
J7—Set the jumper for the desired echo amplification:
X1, X10, X100, or X1000.
J5—Connect the transducer.
J6—Connect an oscilloscope.
J4—Connect a 15VDC power supply capable of delivering
at least 125mA.
Jumper Position & Adjustability
The available models with their corresponding pulse width,
frequency, and voltage range adjustability are shown on
Table 1.
NOTE: These values are approximate.

WARNING: The power supply must be OFF before
making electrical connections.
WARNING: The power supply requires a 0.5 amp
fast-blow fuse or circuit breaker.
IMPORTANT: Please read the instructions completely
before proceeding.
