Affinity Digitiser

Image
  • 31-bit digitiser and network communications unit
  • Stable and robust Linux-powered unit
  • Option for Elliptic Curve Digital Signature Algorithm (ECDSA) scheme data authentication.
Sophisticated and adaptable, high fidelity seismic digitiser.

The Güralp Affinity is a high-fidelity integrated digitiser and network communications unit that provides a convenient and expandable way of connecting analogue and digital seismic instruments to your network.

The Affinity delivers high-quality digitisation with 31-bit resolution. Designed for data quality and durability, the Affinity is a stable and robust Linux-powered unit with on-board storage and networking facilities. An advanced module directly controls power supply to peripherals and reports their voltages via state-of-health communications.

For applications where data verification is critical the Affinity also supports Elliptic Curve Digital Signature Algorithm (ECDSA) scheme data authentication.

The Affinity is available as a four channel or eight channel unit.
