 Sweep Speed — This number represents the sweep speed of the displayed
and recorded analog trace. The sweep speed can be set to 15, 30, or
50 mm/sec. All EEG channels use the same sweep speed.
 Amplitude Grid — This grid is drawn under the analog trace and divides the
amplitude scale into four segments. A dashed line is drawn at the baseline or
center of each display zone. Solid lines are drawn at the top and bottom edge
of the zone (peak values), and dotted lines are drawn halfway between the
edge of the zone and the baseline. Tick marks are drawn on the Y-axis at
each division. Each division represents peak amplitude divided by four.
 Analog Waveform — This trace sweeps from left to right, reflecting brain
electrical activity for the channel monitored.
 Peak to Peak Signal Amplitude — These numbers indicate the maximum and
minimum amplitude ranges of the analog signal (set by user).
 Electrode labels — These number-letter combinations indicate the electrode
lead placement.
 Time Axis — Time is measured along the X-axis for each analog trace. Each
waveform window displays 4-seconds at a sweep speed of 15 mm/sec,
2-seconds at 30 mm/sec, and 1.2-seconds at 50 mm/sec.
Freezing the Display
To freeze the analog waveform, touch the FREEZE ON/OFF key. The ON section
of the key will highlight. Touch the key again to turn off the freeze, and the OFF
section of the key will highlight. Freeze mode is used to stop the moving waveform
so transient features can be captured and inspected.
To enable EMG with trend overlay
and analog EEG:
1 Touch EEG.
2 Touch DISPLAY FORMAT.
3 Select FREEZE ON.
