COMPUTER METHODS AND QUANTUSSERIES

The ALI25 is a high-bandwidth Module designed for triggered/burst acquisition for Pyro-Shock / Mechanical Shock applications. The ALI25 provides anti-alias filtering on the Signal and Sense lines. The Signal lines incorporate three stages of anti-aliasing filters: analogue, digital within the ADC, and digital within the signal processors. A delta-sigma ADC over-samples the Signal 8 times, delivering superior bandwidth and accuracy compared to SAR-based DAQ systems. Each channel includes bridge signal conditioning, a 24-bit 5 M sample/s ADC, and a 21 M sample data buffer. Systems can be configured with 2 to over 1000 channels.

Built-in Signal Conditioning supports bridge-type transducers, ICP^® sensors, and voltage signals. Constant voltage or current excitation is programmable for each channel. Anti-alias filtering in each channel is critical to prevent high-frequency signals from being misinterpreted as lower-frequency components during sampling, ensuring accurate and clean signal acquisition. The ALI25’s robust AA filtering system guarantees precise and reliable measurements. Each input channel has a buffered low noise output channel for monitoring or acquisition sensor data via a secondary system. Measurement Integrity and Sensor Status prior to an event is verified with continuous: pre-trigger monitoring, summarized signal information, and sensor fault detection.

Measurements are triggerable by signal level and persistence, external events, data flow, or software command. This advanced set of triggering options supports multi-system synchronization and ensures event detection.
