22 Description of Parts
Synchronizing Signal Output Terminal
The following signal is provided as a synchronizing signal for other
devices.
The synchronizing signal is output regardless of the MIX, MODU or DC
polarity selector keys or the VOLTAGE setting.
For example, even when the DC key is pressed and no pulse is output,
the END and DELAY pulses are output according to stimulation waveform
setup.
Output impedance: approx. 1 kilohm
Amplitude: approx. +5 V
Pulse duration: approx. 500 µ s

Function
Generates a pulse that is synchronized with the MAIN INTERVAL trigger signal.
Generates a pulse that is synchronized with the last MAIN INTERVAL repeat
pulse. When CYCLES is set to 005 and MAIN INTERVAL is started, the pulse
is output at the fifth main interval.
[Fig.25]
Generates a pulse that is synchronized with the trigger signal created by the
external trigger signal.
