AvaTrigger-USB2 External Trigger Box

Operating Manual

The AvaTrigger is a trigger source that can be used to trigger

an AvaSpec-USB2/EVO spectrometer. The AvaTrigger has two

different settings for external triggering, i.e. an optical

trigger and a pushbutton trigger.

The 3-position switch should be set into the left position to

use the optical trigger. If triggers should be generated

manually by the pushbutton, set the switch to the right. The

trigger box is switched off by setting the switch in the

middle position.

The optical trigger is useful to measure pulsed light sources, the AvaSpec can start integration time

within 1.5 microsecond (depending on the model) after the optical signal starts, or a user specified

delay time later if the spectral output against time needs to be measured. The optical trigger has an

SMA905 connector to easily couple to our comprehensive line of light sources and accessories

through SMA couples fiber optics. The sensitivity of the optotrigger can be adjusted by a

potentiometer at the front side of the AvaTrigger. The green LED at the front side shows a short

pulse when a TTL pulse is put at pin 4 of the DB15 connector at the backside of the AvaTrigger box.

The AvaTrigger comes with an IC-DB26-2 interface cable. This cable needs to be connected between

the AvaTrigger and the AvaSpec-USB2/EVO spectrometer.
