IX-RA-834 - 4 Channel Data Acquisition

Product Summary

The IX-RA-834 recorder is an advanced, feature-rich physiological data acquisition system ideal for a wide variety of research applications.


  • Oocyte applications
  • Epithelial voltage clamp applications
  • Electrophysiology applications
  • Isolated tissue and organ studies
  • Exercise physiology research
  • Metabolic function studies

The IX-RA-834 data recorder from iWorx is an advanced and feature-rich physiological data acquisition system that comes standard with 8 general purpose input channels, a low voltage and high voltage stimulator, 8 digital outputs, a built-in barometric pressure sensor, and 4 iWire inputs. The RA-834 exhibits the high resolution, low noise and flexibility required for a variety of research applications.

Recorder Features:

  • Built-in Barometric Sensor - allows for real-time compensation to pressure measurements due to changes in atmospheric pressure.
    Versatile - record multiple signals simultaneously (i.e. heart rate, respiration and pulse oximetry).
  • Built-in Stimulators - built-in, software controlled low and high voltage stimulators for both human and animal experiments with a wide array of preset stimulation protocols.
  • Longer Life Cycle - iWire digital design accommodates future lab technologies.

Plug and Play Expandable

The IX-RA-834 includes a proprietary Serial Interface technology called iWire. iWire devices enable unparalleled expansion of your laboratory recording equipment by simply plugging in an iWire compatible device. Need to add 4 EMG channels to your protocol? No problem, simply plug in an IX-BIO4 iWire device. Need to record 12 leads of ECG? Simply plug in an iWire compatible 12-lead ECG device into one of the iWire inputs. A traditional data recorder would require 12 additional recording channels to accomplish this.

  • Current iWire devices include:
  • IX-B3G - 3 biopotential channels, plus 1 GSR channel
  • IX-BIO4 - 4 biopotential channels
  • IX-BIO8 - 8 biopotential channels
  • IX-ECG12 - 12 Lead ECG

Software - Versatile, Yet Easy-to-Use Software for Even the Most Advanced Analyses.

LabScribe software is a powerful recording and analysis package that features an intuitive, user-friendly interface for setting up acquisition screens, calibrating signals, and analyzing data. Up to 128 channels of data can be displayed simultaneously at sampling rates as high as 100,000 samples/second.

Specific analysis modules for cardiovascular research are available to analyze pressure signals, blood flow data, ECG recordings, ventricular pressure volume loops and sono micrometry dimension data.

Software Features

  • Intuitive Interface - LabScribe software display data through a customizable, user-friendly interface.
  • Real-Time Calculations - Monitor and observe functional parameters with an array of real-time calculations and user defined computed channels.
  • Data Reduction - Analyze and reduce data and average and write selections of data to the built-in journal or directly to a text file.
  • Real-Time Annotations - Mark data during an experiment with free form text notes.
  • Advanced Analysis - AutoMark specific time points and features of a signal for further analysis and validation.
  • XY Window - Any two channels can be displayed in XY format, online or offline.
  • FFT Analysis - LabScribe includes a Fast Fourier Transform feature for frequency analysis of any signal
