DOVER, USA: iWorx, a developer of advanced physiology research tools, has introduced the IX-100B Data Acquisition System that provides high resolution/low noise recording of biopotential signals such as ECG, EMG, and EEG in small animal cardiovascular research. With one isolated input channel and a low voltage stimulator, the system is ideal for dedicated applications where only one biopotential recording channel is required.
The iWorx 100B uses a 16-bit A/D converter to sample data over its full input range of ±1V at speeds up to 200 kHz. The recorder also offers a wide selection of low pass and high pass filters and gains and is safe for human connection. The recorder incorporates a software programmable 16 bit, +/-5V stimulator (DAC). Parameters for the stimulator, such as pulse width, frequency and amplitude, may be changed “on-the-fly.” Standard protocols include Pulse, Train, and Step; protocols can be customized as well. In isolated heart applications, the stimulator may be programmed for pacing.
The iWorx 100B recorder is controlled by LabScribe2 software, a powerful recording and analysis software package. LabScribe2 has 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 200,000 samples/second.
A comprehensive set of analytical routines have been pre-configured making data analysis and interpretation quick and easy. Specific software modules for cardiovascular research are available to analyze pressure signals, blood flow data, ECG recordings, ventricular pressure-volume loops and sonomicrometry dimension data.
