set_laser_timing
Function defines the output period and the pulse lengths for the laser signals LASER1 and LASER2
for “laser active” operation.
Call set_laser_timing( HalfPeriod, PulseLength1, PulseLength2, TimeBase )
Parameters HalfPeriod half of the output period in bits as an unsigned 32-bit value
•In RTC
®
5 mode:
1 bit equals 1/64 µs. Permissible range: [0 … (2
32
–1)]
•In RTC
®
4 compatibility mode:
1bit equals 1/8µs or 1 µs, depending on the selected time base.
With respect to the specified
TimeBase , the value will be converted to
an integer-multiple of 1/64 µs. The permissible range is correspond-
ingly smaller.
PulseLength1 Pulse lengths of the laser signals LASER1 and LASER2 in bits as an
unsigned 32-bit value.
•In RTC
®
5 mode:
1 bit equals 1/64 µs. Permissible range: [0 … (2
32
–1)]
•In RTC
®
4 compatibility mode:
1bit equals 1/8µs or 1 µs, depending on the selected time base.
With respect to the specified
TimeBase , the value will be converted to
an integer-multiple of 1/64 µs. The permissible range is correspond-
ingly smaller.
(PulseLength2) (as an unsigned 32-bit value)
The value of
PulseLength2 will be ignored and is no longer used.
With the RTC
®
5, the pulse lengths of laser signals LASER1 and LASER2
are always identical and are definable via
PulseLength1 .
TimeBase as an unsigned 32-bit value
•In RTC
®
5 mode, the value is ignored and the clock frequency is fixed
at 64 MHz (1 bit equals 1/64 µs).
•In RTC
®
4 compatibility mode, the TimeBase value is handled as
follows:
=0: sets the time base to 1 MHz (1bit equals 1µs)
0: sets the time base to 8 MHz (1bit equals 1/8µs)
