Product Highlights
The ISO-Z is a low noise, high impedance amplifier head-stage. It's designed to plug into the BMA-931 Bioamplifier Module for applications where it's necessary or desirable to isolate the subject from the data acquisition system. It uses a medical-grade isolation amplifier to isolate the input connections from chassis or earth grounds. The ISO-Z supplies both gain and calibration, further enhancing its performance. The low impedance output of the ISO-Z is able to drive long cables, making it ideal for use in applications where the DI-1000 Series chassis must be located at a distance from the recording site.
