DPR300 Spike Pulser
The DPR300 is a computer controlled ultrasonic pulser/receiver with an extremely low noise receiver. Instrument controls include receiver gain, high and lowpass filter cutoff frequency selection, pulse energy, pulse amplitude, pulser impedance, damping level, pulse-echo or through transmission mode select, pulse repetition rate, and pulser trigger source select. A Manual Control option is available.
The DPR300 is designed for exacting applications. The rapid-recovery receiver is fully shielded from electromagnetic noise and interference to ensure a high signal to noise ratio. In addition, the pulser impedance, pulse energy, and pulse amplitude may be individually adjusted to optimize the excitation pulse for a specific application or transducer.
The DPR300 includes a Windows-based software control program to enable immediate usage in your application. Multiple DPR300’s, and other JSR Ultrasonics instruments can be controlled from one computer using a hardware daisy chain interconnection scheme. Areas of application include computer-controlled imaging and measurement systems, NDE systems, research and development, materials analysis and inspection, transducer evaluation, and exacting low-noise measurement systems.
