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. The signal is then 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 the medical field as well as thickness measurement / flaw detection for industrial inspections and research laboratories. PicoPulser is a great tool for academic research.
