BIS™ Advance Monitor
Frequency response 201.12.1.105 The output at 0.5 Hz and 50 Hz is within
71 % to 110 % of the output obtained
with a 5 Hz sine wave input signal:
4-channel: 101.7% at 0.5 Hz; 95.8% at 50
Hz
2-channel: 104.8% at 0.5 Hz; 90.4% at 50

1.8.1. EEG Particular Standard (IEC
60601-2-26, 3rd Edition)
With regard to immunity to electromagnetic interference, the standard states the
following:
May show temporary degradation during discharges
Shall resume normal operation after ESD within 30 seconds.
Within this context, normal operation for the BIS™ monitoring
system means the EEG wave shall appear on the BIS™ monitor
within 30 seconds .
Shall not lose operator settings or stored data
Shall continue to perform its intended purpose
It is possible, and acceptable per the standard, for the BIS™ monitoring system to
experience a temporary loss of function, or degradation of behavior, due to an EMC
Immunity, that could require operator intervention, provided that the system
resumes normal operation (i.e., displays the EEG analog signal) within 30 seconds.
Depending on the type of error the BIS™ system detects if exposed to significant
electromagnetic interference, the following are examples of operator intervention:
