Airmar T1 Development Kit for Air Transducers Manuel d'utilisateur télécharger pdf

Applications

• For use with Airmar’s Ultrasonic Transducers.

• To aid in designing ultrasonic systems.

• Allows the designer to quickly and easily transmit and

receive echoes.

Features

• Jumper selectable pulse width and frequency for optimal

interfacing.

• 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.
