PCIE-1802 User Manual 2
1.1 Introduction
The Advantech PCIE-1802 is a high-performance data acquisition module specifi-
cally designed for sound and vibration applications. With eight 24 bit analog inputs
per module and IEPE constant current signal conditioning, Advantech’s PCIE-1802 is
ideal for making precision measurements with microphones, accelerometers, and
other transducers that have very large dynamic ranges. The modules deliver 115 dB
of dynamic range and simultaneous sampling on all 8 channels at rates up to 216 kS/
s.
1.2 Features
The PCIE-1802 offers the following main features:
 8 simultaneous analog input channels
 24-bit resolution A/D converter
 216 kS/s maximum sampling rate
 115 dB dynamic range up to 6 gain settings for ranges from ±200 mV to ±10 V
 IEPE for accelerometers and microphones
Some of the features are described in detail on the following pages.
1.2.1 Auto Calibration
The PCIE-1802 card features software auto calibration. It provides a convenient
method for user calibration processing.
1.2.2 BoardID Switch
The PCIE-1802 has a built-in DIP switch that helps define each card’s ID when multi-
ple PCIE-1802 cards have been installed on the same PC chassis. The BoardID set-
ting function is very useful when building a system with multiple PCIE-1802 cards.
With the correct BoardID settings, you can easily identify and access each card dur-
ing hardware configuration and software programming.
1.3 Applications
The following are some of the possible applications of PCIE-1802 cards:
 Noise, vibration, and harshness (NVH) detection
 Machine status monitoring
 Structural health monitoring
