4.13.1 EEG & EP Setup
Service data in Headbox view
EP Start/Stop
is highlighted when the EP Start/Stop
button is pressed in the headbox or module.
Imp. Check
is highlighted when the Imp. Check
button is pressed in the headbox or module.
Active
shows 1 if the channel is active.
Lead off+
shows the lead off status of all plus
electrodes. 0 means that the lead is on and 1 that
the lead is off.
Lead off-
shows the lead off status of all minus
electrodes. 0 means that the lead is on and 1 that
the lead is off.
Imped+
shows the impedance of plus electrodes of
the last impedance check in all channels.
Imped-
shows the impedance of minus electrodes of
the last impedance check in all channels.
BSR
shows the burst-suppression classification of
EEG waveforms. 0 means artifact, 1 suppression, 2 burst and 3 invalid (the EEG is not classified).
Artefact
shows the artefact status of all channels. 0 means that there are no artefacts on the signal and 1
means that there are artefacts.
Noise
shows 1 if the activity of FEMG is too high for clean EEG signal and that EEG is not probably reliable.
EMG AD
shows the latest AD conversion result of FEMG signal without any filtering or scaling.
Leadset AD
shows the latest AD conversion result of lead set signal without any scaling.
Bipolar
shows the montage type that is active in the module and headbox. 1 means bipolar and 0
referenced.
60 Hz
is 1 if the power frequency filter is set for 60 Hz power frequency.
Imp. Meas.
shows 1 if the impedance measurement is on in the headbox.
Imp. Check Failed
shows 1 if the impedance check has failed.
Mu
EP Meas.
shows 1 if the evoked potential measurement is active in the headbox.
High EP Sampl. Rate
shows 1 if the headbox uses higher sampling rate for 10 ms EP measurement.
EP Epoch Points
shows the number of samples collected for each epoch.
EP Channels
shows the number of channels used in EP measurement.
Hb ROM Error
is 1 if the checksum at the EPROM is not in accordance with the one the software has
calculated.
