Introduction - ICP DAS USA PET-AR400 User Manual

1. Introduction

The PET-AR400 is a high speed data acquisition device. The PET-AR400 built-in an Ethernet
communication port for data transfer over the network and includes 4 IEPE inputs (128 kHz for 1
channel; 32 kHz for 4 channels) for measuring the signal from an IEPE accelerometer.
The PET-AR400 also provides 4 kV ESD protection as well as 2500 VDC intra-module isolation. In
addition, the 24-bit ADC includes built-in Sinc3 filtering to adjust the appropriate sampling rate and
filter out modulator and signal noise.
The PET-AR400 is not only suitable for a wide range of mobile/portable measurement applications,
but also for precision signal measurement.
PET-AR400 supports many kinds of trigger modes for A/D conversion：software trigger, analog
threshold trigger. The software trigger can acquire a sample whenever needed; The analog
threshold trigger will collect data while the analog input value is higher or lower than specific
voltage value.
