FWPD - Real-time pulse detection firmware

Overview

The core challenge in pulse detection is to design a system for random events. The Teledyne SP Devices’s firmware option FWPD, for the ADQ14 and ADQ7, is tailored to detected and analyze pulses in demanding measurement applications where the properties of the pulses (such as timing or length) are not known in advance.

With high sampling rate, high vertical resolution, and sophisticated signal processing methods, regions of interest are distinguished and collected. Since only the regions of interest are collected, and all other data is suppressed, the magnitude of data reduction is significant.

• Digital baseline stabilizer (DBS) and moving average (MA) filter contribute to a stable baseline and reduced pattern noise.
• The sophisticated Peak detection offers dynamic recording, zero suppression, and a dynamic level trigger. It also includes additional timing rules for when pulses should be accepted.
• The Peak analysis in the FPGA allows for real-time characterization of the identified pulse.
• Several modes of Data collection is offered to transfer data to the host.
• Latency control is enabled with optional padding of zeros, to guarantee a minimum throughput.
• Timestamp allows for real time timing of an event.
