The DE-916 High-performance Isolated Dynamic Signal Test and Analysis System is specially designed for accurate capture of transient signals in a strong interference environment. By means of multi-layer shielding technique, DE-916 effectively eliminate electromagnetic radiation and conduction interference, and ensure the accurate measurement of force, pressure, stress, strain, displacement, velocity, acceleration and other physical quantities.
Modular design, expandable to over 500 channels via Ethernet
Independent 16-bit SAR A/D per channel, multiple channel parallel operation, no interaction between channels
Built-in bridge completion and Excitation
Multi-layer shielding and advanced isolation technology, electromagnetic noise and conducted interference eliminated effectively
Up to 20MH/channel for transient sampling rate and 1MHz/channel for continuous sampling rate
CMRR over 120dB
Built-in 24V/4mA biasing circuit, used to acquire the output signal of IEPE acceleration sensors and microphones
Built-in Butterworth low-pass filter
DMA real-time data transfer for ensuring the high-speed and stable transmission of data without drop-out
