Figure 3-3. Filter value out connector.
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:
DAC Output = FILTER NUMBER x 400 mV
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.
ƒ
MOVE ON COMMAND (default mode)
ƒ
MOVE ON STROBE PULSE
ƒ
MOVE ON SYNC PULSE
ƒ
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
