•
Note that half the period length must be specified for
HalfPeriod
(see figure 48 on
page 131 and figure 49 on page 134).
•
If
HalfPeriod
= 0 and/or
PulseLength1
= 0, no laser signals will be outputted.
• If the softstart mode is used (see page 135),
HalfPeriod
should not be smaller than 104
(this is not automatically checked). This value corresponds to a laser pulse frequency of
approx. 308 kHz.
•If
PulseLength1
is larger than the output period (2 ·
HalfPeriod
), the laser will be
permanently on.
• The time base setting applies only for the parameters of this command.
•For RTC
®
4 compatibility mode, SCANLAB generally recommends setting the time base
to 8 MHz. In this mode, a time base of 1 MHz should only be chosen if necessary.
• Refer to chapter 7.4 "Laser Control", page 128, for details.
•In RTC
®
5 mode, the command set_laser_timing is identical to set_laser_pulses.
• The signal level is defined via set_laser_control.
• In laser mode 4 and laser mode 6, the time base for signals LASER1 and LASER2 is inde-
pendent of
TimeBase
and always 1/64 µs (in RTC
®
5 mode) or 1/8 µs (in RTC
®
4 compat-
ibility mode).

5 • With the RTC
®
5, the pulse lengths of laser signals LASER1 and LASER2 are always iden-
tical.
• Clock frequency:
- in RTC
®
5 mode: fixed clock frequency of 64 MHz
- for the RTC
®
4 and in RTC
®
4 compatibility mode: 1 MHz or 8 MHz

List Command
set_list_jump
Function Execution produces an unconditional jump to the specified address within the list buffer.
The next command there will be executed immediately without delay.
Call
set_list_jump( Pos )
Parameter
Pos
absolute jump address [0 … (2
20
–1)] as an unsigned 32-bit value
Comments • The set_list_jump command is synonymous with list_jump_pos – see the comments
there.
