81
this is the lowest value where a trigger signal is
generated
unit µm or mrad
trgse
upper trigger position
this is the highest value where a trigger signal is
generated
unit µm or mrad
trgsi
trigger interval
this is the distance between the trigger points
unit µm or mrad
trgedge
trigger edge
this value depends on which direction the trigger
point must be reached for trigger generation
0: trigger disabled
1: trigger at rising edge
2: trigger at falling edge
3: trigger at both edges
trglen
trigger length
this values depends on the duration of a trigger
impulse
(n * 20µs n = 1
…255)
trgsrc
trigger source
selects real position value or setpoint for trigger
generation
0 = real position value (measured)
1= setpoint
trgos
trigger offset
shifts the trigger points when triggering on
setpoint
[µm] or [mrad]
table 13: commands for trigger generation
Hardware:
The output for trigger signals is the 9-pin D-Sub connector
“ANALOG”.
The pin 7 (trigger out) and pin 8 (ground) are used.
sketch 4: internal circuit
8.8 scan function
The scan allows the output of exactly one period of the function generator (sine or triangle). This
will require that the relevant functional parameters be set (frequency, amplitude, offset or
