Name
BTrigger level adjustment knob
(EXT TRIG LEVEL)
Selects whether the trigger is activated at the signal level that is input to the
external trigger terminal (on rear).
Adjustment range: 0 to ±10 V.
If the sweep-wave output from the oscilloscope is used as the external trigger
signal, the stimulation pulse can be monitored at any position on the oscilloscope
tube by setting the level adjustment knob.
Allowing for a noise margin and hysteresis in the built-in comparator, use a
trigger signal to oscillate up to about 1 V lower than the trigger level.

signal
External trigger pulse
When set to SYNC
When the knob is turned fully counterclockwise until it locks (SYNC position),
the trigger level is approximately +3 V.
When activating the trigger at a pulse of +5 V, the inconvenience of setting
the level can by avoided by using this position.
Function
Approx. 1 V or more is needed
