Comments on the Data (cont’d)
• Note when evaluating data recorded with active Tracking Error compensation
(set_timelag_compensation):
– A call of set_timelag_compensation( TimelagXY < TimelagZ ) delays the xy axis as
well as the Laser Control Signals by [ TimelagZ – TimelagXY ]
– For Signal1 , Signal2 = 7, 8, 10, 11, 13, 14, 20, 21 the undelayed x axis/y axis control
value is recorded respectively
– In contrast to the recorded values, for Signal1 , Signal2 = 20, 21, the actual control
value is outputted at the scan head connector with a [ TimelagZ – TimelagXY ] delay.
– For Signal1 , Signal2 = 0, the LASERON signal delayed by [ TimelagZ – TimelagXY ] is
recorded.
• Signal1, Signal2 = 24 enables logging of the signal parameter that is outputted by
“Automatic Laser Control“ (but not with vector-defined laser control; see
set_auto_laser_control). Logging only occurs when “Automatic Laser Control“ has
been activated and the laser is on.
When the laser is switched off, 0 is recorded.
With “Spot Distance Control”, signal 24 has no direct meaning, it does not mean
“HalfPeriod” in particular.
• Signal1 , Signal2 = 31 enables logging of the signal parameter specified for “vector-
controlled laser control” (see set_vector_control). Logging is also possible without
executing [*]para[*] Commands, but then the signal values remain unchanged.
• Pulse length and output period ( Signal1 , Signal2 = 37, 38) are only logged for Signals
for “Laser Active” Operation (not for standby signals). In Softstart Mode (not yet
implemented) and in Pixel Output Mode, the pulse length and output period might
possibly change faster than the 10 µs clock cycle (time resolution of logging by
set_trigger). These values cannot be recorded.
• For Signal1 , Signal2 = 39…42 and 48…51, see Chapter 6.9.1 ”Free Variables”,
page 135.
RTC4RTC6 Basically unchanged functionality. However:
• The measurement session can be aborted by Period = 0.
• The signals StatusAZ and StatusBZ ( Signal1 / Signal2 = 3, 6) are no longer available.
• All coordinate values are referred to (0|0|0) (value range [–2
19
…(2
19
–1)]) and are no
longer zero point shifted.
RTC5RTC6 Basically unchanged functionality.
Increased memory area for data recordings by merging channels, see set_trigger4.
Version info Available as of DLL 600, OUT 600, RBF 600.
Change: DLL 610, OUT 610, RBF 615: endless recording.
