List Command
set_laser_pulses
Function Defines the output period and the pulse lengths of the Laser Control Signals LASER1 and
LASER2 for “laser active” operation.
Call set_laser_pulses( HalfPeriod, PulseLength )
Parameters HalfPeriod Half of the output period. In bits.
As an unsigned 32-bit value.
1 bit equals 1/64 µs.
Allowed value range: [0…(2
32
–1)].
PulseLength Pulse length of the Laser Control Signals LASER1 and LASER2. In bits.
As an unsigned 32-bit value.
1 bit equals 1/64 µs.
Allowed value range: [0…(2
32
–1)].
Comments • By the HalfPeriod parameter, half the period duration is specified, see Figure 52 and
Figure 53.
• If HalfPeriod = 0 and/or PulseLength = 0, no Laser Control Signals are outputted.
• With PulseLength  (2 × HalfPeriod ), the laser remains on all the time.
• The signal level is defined by set_laser_control.
• set_laser_pulses is also available as the control command set_laser_pulses_ctrl.
• set_laser_pulses is largely identical to the RTC4 command set_laser_timing, but has
less parameters.
RTC4RTC6 New command.
In RTC4 Compatibility Mode, the RTC6 multiplies the specified values for HalfPeriod and
PulseLength by 8. The allowed value ranges decrease accordingly.
RTC5RTC6 Unchanged functionality.
Version info Available as of DLL 600, OUT 600, RBF 600.
