PicoPulser is an ultrasonic pulser/receiver that can be used as a standard desktop pulser/receiver. The PicoPulser transmits a high voltage pulse with adjustable pulse width when triggered by an external trigger signal or by the internal PRF timer. The receiver on the PicoPulser then processes the received signal through the amplifier and a band pass filter. Then the signal is ready at the RF connector for an oscilloscope to display or an analog to digital converter to digitize.

The PicoPulser can be triggered with a TTL trigger source in the external trigger mode.

The adjustable parameters include pulse width, pulse voltage, and gain with potentiometers by using a small screw driver. The selectable parameters include transducer mode (single element or dual element), and internal trigger/external trigger. Customized parameters can be done upon request.

Applications include disease diagnostics for medical field, and thickness measurement / flaw detection for industrial inspection and research laboratory. PicoPulser is also a good tool for university graduate students to conduct their experiments and write their thesis.
