Product Details

As an entry-level unit, ease of use is a priority, and the FSA 3500-P offers true plug and play connectivity via FireWire® interface—even with laptop computers! With sampling rates to 400 MHz and 8-bit analog-to-digital conversion (ADC), the powerful FSA 3500-P thrives on high speed and low SNR flow situations. Water channel flows, gas jets, films, combustors, large test section (long focal length) wind tunnels are all now fully open to characterization by FSA 3500 based PDPA systems.
