ADLINK Technology introduced the PXIe-9529 dynamic signal acquisition module. The PXI Express card features up to eight 24-bit analog input channels simultaneously sampling at 192 kS/s and a 108 dB dynamic range to provide ample power for high density, high channel count signal measurement. The PXIe-9529′s 8-channel design provides easy expansion up to 136 channels in a single 18-slot PXI Express chassis while still maintaining tight timing and synchronization between channels. It is ideal for high channel count applications like phased array data acquisition.
ADLINK PXIe-9529 Dynamic Signal Acquisition Module Features
- PXI Express specification Rev. 1.0 compliant
- 24-bit Sigma-Delta ADC
- 8 simultaneous sampling analog input
- 192 kS/s maximum sampling rate
- AC or DC input coupling, software selectable
- One external digital trigger input
- Support IEPE output on each analog input, software configurable
- Full auto-calibration
The PXIe-9529 features a vibration-optimized lower AC cutoff frequency of 0.3 Hz, and all input channels incorporate 4 mA bias current for integrated electronic piezoelectric (IEPE) signal conditioning for accelerometers and microphones, positioning the module for machine condition monitoring; noise, vibration and harshness (NVH); and phased array data acquisition applications.
The PXIe-9529′s built-in phase-locked loop (PLL) enables multiple modules to lock to an external reference-timing signal, such as PXI_CLK10 or PXIe_CLK100 from the PXI chassis backplane, such that each module can perform measurements simultaneously. In addition, the PXI star trigger ensures synchronization between modules with less than 1 ns of skew, allowing 0.01 deg phase system mismatch for a 1 kHz signal between any two channels across devices, with the subsequent variety of implementation enabling simultaneous precision multi-channel sampling.
The PXIe-9529 provides flexible input ranges up to ±10V or ±1V, software-selectable AC or DC coupling, and both differential and pseudo-differential input configuration, with up to ± 42.4V over-voltage protection for positive and negative inputs in both configurations.
The PXIe-9529 supports Windows 8, Windows 7, Windows XP operating systems, and is fully compatible with third-party software such as LabVIEW, MATLAB, and Visual Studio.NET. In addition, ADLINK’s easy-to-use DSA (Dynamic Signal Assistant) Utility is included at no extra charge, allowing system integrator validation and reducing overall design cycle time with no programming required.
