Trident 305 Digitizer

Summary

The Trident 305 is an industry-leading digitizer, designed for use with the Taurus Portable Seismograph or Cygnus transceiver. The Trident 305 features 24-bit performance in a compact, robust package offering typical dynamic range of 142 dB.

The Trident 305 Digitizer’s versatility allows for an optimal network design flexibility. Numerous Trident 305 digitizers can be daisy-chained to form a multi-channel system. Such scalability makes Trident 305 well suited to fixed, portable and structural monitoring networks.

Because the Trident 305 Digitizer includes comprehensive seismometer control functions, it allows for seismometer mass centering, mass positioning, monitoring and calibration from a central site, eliminating the need for frequent site visits.

Since the Trident 305 is not packaged with communications interface and timing systems, it can be deployed within the seismometer vault’s temperature-stable environment for improved long-period performance and superior data quality.

In addition, the Trident 305 Digitizer supports bi-directional data communications, timing and power distribution, allowing for a simple twisted-pair NMXbus cable between the digitiser and the communications interface. This feature eliminates the need to use long RF and GPS cables to accommodate the positioning of GPS, VSAT or RF antenna, reducing cost and increasing site configuration options.

Benefits
