External Mode Triggering Methods
The following pages describe the three different triggering methods for
External Mode synchronization. The three methods for External Mode
synchronization are using :
• Flashlamp External Q-Switch Internal
• Flashlamp Internal Q-Switch External
• Flashmap External Q-Switch External
WARNING: Refer to the External Trigger Signal
Requirements on page 52
for proper external flashlamp
and Q-Switch trigger pulse requirements.

Triggering Method Result
Internal External The ICE450 generates the flashlamp pulse signal. The
Q-Switch trigger signal is generated by an external
source. This provides better resolution for the Q-Switch
delay than is available from the ICE450 internal setting.
Typically, you will connect to the BNC “Lamp Out” and
use this signal to synchronize your external signal
generator supplying the Q-Switch pulse. The Lamp Out
signal is a copy of the actual flashlamp trigger.
To use this mode:
1. From the
Main menu
, select the
Flashlamp
menu.
2. Set
flash sync
to
INT
.
3. Return to the
Main menu
and select the
Q-Switch
menu.
4. Set
QS Sync
to
EXT
