Sync; Dac; Strobe; Line Power - Sutter Instrument Lambda DG-4 Operation Manual

3.5.4 Sync

This BNC connector is the video synchronization input. NOTE: THIS INPUT IS NOT
INTERNALLY GROUNDED. If the ground in the camera being used is floating, the camera's
synchronization signal to the Lambda DG-4/5 SYNC input will cause the galvanometers to
oscillate at a high, irregular rate.

3.5.5 DAC

This BNC connector provides an analog indicator of the current FILTER NUMBER:

3.5.6 Strobe

This BNC connector is the "trigger" input for the MOVE ON TRIGGER mode of operation.

3.5.7 Line Power

This socket is used to connect the power cord provided with the Lambda DG-4/5.

3.6 Fuse

The fuse used in this instrument depends on the power rating of the installed lamp and
mains voltage. See APPENDIX C (FUSE REPLACEMENT) for fuse-type details and fuse
installation.

3.7 Modes of Operation (LOCAL)

3.7.1 General Information

Filter switch timing can be controlled using one of four different operational modes.
MOVE ON COMMAND (default mode)
MOVE ON STROBE PULSE
MOVE ON SYNC PULSE
MOVE ON SYNC PULSE, INHIBITED BY THE STROBE LINE
The default mode ("MOVE ON COMMAND") allows you to directly command filter changes
(e.g., using the numeric keys on the keypad when the Lambda DG-4/5 is under LOCAL
("Manual") control). Filter changes can also be controlled using an external trigger ("MOVE
ON STROBE PULSE"), video synchronization pulse ("MOVE ON SYNC PULSE") or a
