PCIe-9529
1 Introduction
The PCIe-9529 is a high-performance 8-CH 24-Bit 192 kS/s
dynamic signal acquisition module, specifically designed for appli-
cations such as structural health monitoring, noise, vibration, and
harshness (NVH) measurement, and phased array data acquisi-
tion.
The PCIe-9529 features 24-bit simultaneous sampling at 192 kS/s
over 8 channels, and a 110 dB dynamic range, providing ample
power for high-density, high channel count signal measurement,
and vibration-optimized lower AC cutoff frequency of 0.5 Hz. All
input channels incorporate 4 mA bias current for integrated elec-
tronic piezoelectric (IEPE) signal conditioning for accelerometers
and microphones.
The PCIe-9529 is auto-calibrated with an onboard reference cir-
cuit calibrating offset and acquiring analog input errors. Following
auto-calibration, the calibration constant is stored in EEPROM,
such that these values can be loaded and used as needed by the
board. There is no requirement to calibrate the module manually.
