Hybrid Input Board (retired)

Fits Digital Lynx SX backplane, adding 32 Hybrid-coupled channels per board to the Digital Lynx SX data acquisition system for seamless integration of differential amplifiers.

This backplane module provides 32 Hybrid-coupled channels to the Digital Lynx SX data acquisition system. It seamlessly integrates extremely low noise differential amplifiers with 24 bit A/D converters sampling at rates between 20 kHz and 40 kHz.

With each Hybrid-coupled channel, both large DC potentials (up to ±1 V) and small AC signals (up to ±132 mV) can be measured without any DC electrode offset saturation. Each channel also boasts very high CMRR, ensuring exceptional reference subtraction and immunity from external interference sources.

  • Replaced by the Digital Lynx Combo Board in 2017

  • Can be used alone with its internal jumper reference selection, or in combination with a DRS-36 Board for programmable reference selection

  • 24-bit A/D converters (value of 6th bit is 1 µV) - ensures wide input range & high voltage precision

  • A direct replacement for the AC Input Board
