usbACQ & usbAMP

Analog physiological signals need to be digitized, and sometimes amplified, before being acquired by IOX2 software. For this purpose, we offer two USB-based devices that are ideal for a variety of preclinical experiments:

  • usbACQ is designed to acquire and digitize high-level analog signals that are pre-amplified up to ±10 volts.
  • usbAMP is designed to acquire and amplify biopotentials and signals from strain gauge-based transducers.

Analog signal already amplified

The usbACQ device is used to interface between a pre-amplified transducer and the acquisition computer.

It provides high resolution analog-to-digital conversion and transfers data to the computer via a USB cable. 

Biopotential electrodes & strain gauge transducers

Biopotential electrodes (multi-lead or single lead ECG, EEG, EMG) and strain gauge transducers (force, pressure…) can be connected to the usbAMP device, that powers strain gauge transducer, amplifies signals, and performs analog-to-digital conversion.

Data transfer to the computer is done via an USB cable. 


Basic system

A typical setup includes:

  • Computer running IOX2 data acquisition software
  • usbACQ or usbAMP device
  • USB cable
  • Transducers

easyMATRIX3 allows to collect and combine synchronized signals from telemetry implants and any other source (analog signal, biopotential electrodes, strain gauge transducers).
This is particularly useful for cardio- or neuro-respiratory applications. For instance, pleural pressure from an implant and respiratory flow from a head-out plethysmography can be simultaneously recorded, for precise resistance & compliance measurement.
