PET-AR400 is a high speed data acquisition device with a built-in Ethernet communication port for data transfer over a network, and includes 4 high-speed 24-bit differential IEPE input channels (128 kHz sample-and-hold @ one channel).
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 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.
The software trigger mode can command the trigger to perform continuous or N data A/D acquisition when needed, on the other hand, when the trigger mode is set to Analog Threshold Trigger mode, the A/D will start collecting N data when the analog input value is above or below a certain voltage.
