24 February 2005 -- LDS Nicolet has released the latest hardware addition to the Genesis data acquisition system: the Universal input amplifier.

This unique, high-end, ultra-fast amplifier serves a variety of needs; from differential and/or isolated measurements to ICP-based vibration or shunt-based current measurements. The name “Universal” truly applies to this board.

The universal amplifier has four input channels, each sampling at 1 MS/s with 16 bit resolution. The bandwidth is 500 kHz and a selection of time or frequency domain optimized filters is available to eliminate noise if needed.

The voltage range for a channel can be set from ±10 mV to ±100 V, making the board adaptable to nearly every application.

True optical isolation allows for measurements with up to 250 V RMS common mode voltage.  The differential input amplifiers eliminate noise picked up in the device under test or the measurement leads. The amplifier typically offers a high CMRR of 80dB.

By switching a menu selection to “ICP mode”, the amplifier supports any type of constant current supplied vibration and acceleration sensors. In “Current mode”, the built-in shunt can be used to measure up to 1 ampère in a safe, isolated and fused manner, without the need of external shunt resistors.

Together with the Genesis, this Universal amp can be used to acquire up to 28 channels in a single mainframe. Data of all channels is stored in parallel with 1 MS/s per channel to as much as 3.5 GB RAM or stored continuously to hard disk at nearly the same speed.
