Description

FREQUENCY RANGE

The GL-PS2 digital seismometer houses a built-in, fully-fledged three-dimensional displacement conversion short-period seismometer with an observation frequency band spanning from 2 seconds to 50 Hz. Its monitoring capabilities are seamlessly integrated into the data acquisition component. The built-in data acquisition unit efficiently handles the extraction, filtering, and real-time calculation of three-channel collected data. It offers users two FIR filter options: minimum phase and linear phase. The collector features an embedded Linux operating system, endowing the GL-PS2 with robust data storage management and data servicing capabilities.

DATA STORAGE AND TIMING

Through the LAN network interface, it supports multi-channel continuous real-time data stream transmission and remote FTP data file downloads. With 8G of built-in memory (expandable), it facilitates the long-term storage of real-time collected data. The time signal input utilizes IRIG-encoded GPS signals and supports NTP network timing functions, ensuring precision and reliability with a synchronization time difference of less than 0.01ms and clock stability better than 0.5ppm.
