Getting Started
The PXIe-4480 and PXIe-4481 are 6-channel, 24-bit analog input dynamic signal acquisition
modules. The modules provide six simultaneously sampled analog input channels and support
sample rates of up to 1.25 MS/s per channel in frequency domain mode and 20 MS/s per channel
in time domain mode.
The PXIe-4480/4481 modules offer excellent dynamic range, noise and distortion performance,
and simultaneous sampling and synchronization capabilities, making them well-suited for many
applications including, but not limited to:
•
Audio testing
•
Acoustic measurements
•
Environmental noise testing
•
Vibration analysis
•
Noise, vibration, and harshness (NVH) measurements
•
High speed blast and pressure events
•
Underwater transient acoustic measurements
The PXIe-4480 offers a large set of sensor conditioning features, including charge measurement,
voltage excitation, IEPE excitation, and TEDS. For applications where the sensors are externally
powered, the PXIe-4481 provides the same voltage measurement performance as the
PXIe-4480, but without the embedded sensor excitation.
Installation
Refer to the
PXIe-4480/4481 Getting Started Guide
for information about installing,
configuring, and setting up the PXIe-4480/4481 Dynamic Signal Acquisition (DSA) analog
input module.
Driver support for the PXIe-4480/4481 was first available in NI-DAQmx 16.1. For a list of
devices supported by a specific release, refer to the NI-DAQmx Readme, available on the
version-specific download page or installation media.
