PCI/PXI-9527
24-Bit High-Resolution Dynamic Signal Acquisition and Generation Modules
PCI-9527
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.

■ Dynamic Signal Assistant
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.
