24-Bit High-Resolution Dynamic Signal Acquisition and Generation Modules

PCI/PXI-9527

Introduction

The PCI/PXI-9527 is a high-performance, 2-CH analog input and 2-CH analog output dynamic signal acquisi-

tion module. This module is specifically designed for audio testing, acoustic measurement, and vibration

analysis applications.

The ADLINK PCI/PXI-9527 features two 24-bit simultaneous sampling analog input channels. The 24-bit

sigma-delta ADC provides a sampling rate up to 432 kS/s at high resolutions, making it ideal for higher

bandwidth dynamic signal measurements. The sampling rate can be adjusted by setting the module DDS clock

source to an appropriate frequency. All channels are sampled simultaneously and accept an input range from

±40 V to ±0.316 V. The PCI/PXI-9527 analog input supports software selectable AC or DC coupling and 4

mA bias current for integrated electronic piezoelectric (IEPE) sensors.

The ADLINK PCI/PXI-9527 also has two channels of 24-bit resolution, high fidelity analog output. The outputs

occur simultaneously at software programmable rates up to 216 kS/s. A software programmable output range

of ±0.1 V, ±1 V, and ±10 V is available on the output channels.

ADLINK’s Dynamic Signal Assistant is a ready-to-run

software utility designed for dynamic signal acquisition

modules, such as the PCI/PXI-9527. This software

provides a windows-based configuration interface

for setting parameters, in addition to a real-time

visualized data display on the screen. An instrument-

like user interface is also provided for basic waveform

generation. The Dynamic Signal Assistant can also log

data acquired from hardware modules. With the Dynamic

Signal Assistant, signal acquisition and generation can be

performed in just a few minutes without any programming

effort.
