Description

BISx 

The BISx identification information is permanently marked on its rear panel. This information includes instrument model and serial numbers and cautions.

The BISx contains the inputs, amplifiers, and digitizers for two channels of EEG, and contains the circuits to digitally process the EEG data and compute the processed parameters. It has a single point connection that connects via a Patient Interface Cable (PIC) to a BIS sensor. The sensor and PIC contain circuits for identifying them to the monitor. This permits the monitor to configure automatically. .

The BISx contains circuits for injecting self-test voltages into the amplifier inputs. It constantly monitors the combined source impedance from the sensor electrodes and is able to measure the individual impedance of the channel and ground electrodes.
