External synchronization measurement
When measuring the spectral of a flash lamp, laser, and other pulsed light
with this system, use the external synchronization measurement mode. See
timing chart below.

Method
1) Connections
Input the trigger signal to the TRIG. IN terminal at
TTL/High impedance using a BNC-BNC cable.
2) Operation
Set Trigger MODE to External and the Number of
Cycle from the application software. Next measure
the data using the data measurement function.
