Chapter 5: Triggering
Synapse provides a versatile platform with respect to synchronizing to the end-user’s
experimental equipment. The detector provides two TTL level I/O signals, via SMB
type connectors on the rear of the unit, for monitoring and/or control of various user
accessories.
To avoid connection errors, a male gender SMB is utilized for the TTL input signal
associated with the External Trigger Input function, while its female gender
counterpart provides for the detection system’s TTL output signal capability. It
should be noted that this TTL output signal functionality provides the end-user with
the ability to select, via SynerJY software, one of three available signals for use in the
experiment as follows:
TTL Output Options:
SHUTTER
The SHUTTER signal provides status with respect to shutter operation and is
activated during the interval when the CCD is being exposed to light.
START
EXPERIMENT
The START EXPERIMENT signal indicates the start of an experiment. Upon receipt
of a “Start Acquisition” command, this output goes to its active state after completion
of its present CCD array cleaning cycle. For time-based operation, this output remains
active until all spectra have been taken and then returns to its inactive state.
EXT TRIGGER READY
The EXT TRIGGER READY signal is applicable to the detection system’s External
Trigger mode of operation and is used to indicate when the system has completed the
current spectral acquisition (i.e. exposure and readout) and is ready to begin
subsequent acquisitions.
Refer to Appendix C for additional information regarding enabling/configuring these
TTL level I/O signals.
Note
:
Each selected output signal can also be
configured, via software, for a specific polarity
where the active state can be either a logic high
(5V) or logic low (0V) to meet the needs of the
experiment.
