AAE Energy Sources, CSP-NP

The Compact & Lightweight Solution for Shallow-Water Coastal Surveys

Product Overview

The Applied Acoustic Engineering (AAE) CSP-NP is a compact, highly portable seismic energy source designed primarily for shallow-water geophysical surveys. As the smallest and lightest unit in the CSP range, it is specifically intended for use with Boomer plates (AA251/AA301) and small Dura-Spark arrays (L80/L200) on small vessels of opportunity.

Despite its small size, the CSP-NP has been recently upgraded to include Reverse Voltage Technology. This allows it to support the modern Dura-Spark range by providing the negative polarity required to preserve electrode life and produce a cleaner acoustic pulse.

Why Choose the CSP-NP?

• Exceptional Portability: Weighing only 35 kg, the CSP-NP can be easily handled by a single person. It is the ideal "backpack-sized" solution for river, canal, and coastal surveys where deck space is at a premium.
• Dual-Voltage Versatility: Its ability to toggle between standard and reverse voltage modes makes it compatible with both traditional boomer plates and modern, high-resolution sparkers like the L80.
• Automatic Variable Input Power (AVIP): Includes "soft start" circuitry that limits the initial current draw. This allows the system to operate safely using small portable generators (as low as 3.5kVA) without risk of tripping breakers.
• High Repetition Rate: Capable of firing up to 6 pulses per second, providing the high horizontal data density needed for identifying fine-scale stratigraphic features and small buried objects.
• Proprietary Pulse Shaping: Features internal circuitry that optimizes the discharge to create a sharp, repeatable acoustic signal with minimal reverberation or "ringing."
