Front End

This module is mainly responsible for interface and control of ultrasonic transducer and also does the
data delay summing on the received raw data. The processed data is send to Back end module for
further DSP processing, display and storage. The Front End Module consists following two PCB’s:

1) TxRx Board

2) Connector Board

5-2-2-1

Transmit/Receive PCB (TxRx)

TxRx includes 48-channel transmit and receive circuits in a single board. This board is mainly divided
in to five sections:

1.) Three 16-channel transmit pulse generators

2.) 48- High voltage transmit drivers

3.) Six octal voltage control attenuator/gain amplifier

4.) Six Octal high speed analog to digital converter

5.) Three 16-channel receive delay summer
