Ctrl Command set_scanahead_laser_shifts
Function Only for scan systems with SCANahead technology, for example, the excelliSCAN.
Shifts the LASERON signals and LaserOff temporally forward or back.
Call set_scanahead_laser_shifts( dLasOn, dLasOff )
Parameters dLasOn Time shift of LASERON signal in [1/64 µs].
As a signed 32-bit value.
dLasOff Time shift of LaserOff in [1/64 µs].
As a signed 32-bit value.
Comments • set_scanahead_laser_shifts lets you fine-tune the Laser Delays, for example, to
compensate laser signal propagation times or to take the laser system switching
behavior into account.
• If set_scanahead_params has not been already called and automatic calculation has
not been activated (activate_scanahead_autodelays Mode = 0 ), then the values only
get stored, but not applied. But they are applied as soon as required conditions are
fulfilled.
• There is a transport delay from the RTC6 board to the scan head of 20 µs. As of
DLL 605 this is automatically taken into account. dLasOn and dLasOff parameter values
optimized for < DLL 605 must be decreased by 20 µs to be suitable for  DLL 605.

Version info Available as of version DLL 600, OUT 600.
Change as of version DLL 603, OUT 603, RBF 607: increased parameter resolution is now
1/64 µs instead of 1/2 µs.

Command
set_scanahead_laser_shifts_list
Function Only for scan systems with SCANahead technology, for example, the excelliSCAN.
Like set_scanahead_laser_shifts, but an undelayed short list command.
Call set_scanahead_laser_shifts_list( dLasOn, dLasOff )
Parameters dLasOn See set_scanahead_laser_shifts.
dLasOff See set_scanahead_laser_shifts.
Comment • set_scanahead_laser_shifts_list takes effect upon the next to-be-calculated delay.
