8.10 Data recorder
The data recorder consists of two memory banks that are written to in parallel. In this way, two individual
signals can be stored synchronously.
Example:
A jump via the set command is used to trigger the data recorder and measure the piezo position and
the current of amplifier 1 for 25 ms.

8.11 Trigger
8.11.1 Trigger In
Various controller functions can be carried out with the trigger input. This can be used to synchronize
the controller with several other
NV200/D NET
controllers or any other external device.
The trigger input uses a 5V logic and is activated by rising edges.

1
Start the arbitrary waveform generator (equal to
grun,1
), then it switches to synchronization (trgfkt,
3)
2
Increment the arbitrary waveform generator index
3
Set the arbitrary waveform generator index to the start value (
goarb+gsarb
)
4
Synchronize the ILC counter/ Set the internal counter to the beginning of the setpoint curve
5
Start the data recorder (equal to
recrun,1
)
