Overview
Digital Function Generators

Digital function generators provide the Mössbauer driving systems with the reference signal, which determines the waveform of the source motion.

WissEl offers three different digital function generators differing in the number of waveforms they can generate (see the following table).
For detailed information about the individual function generators click on the respective figure or name in the table.

Notes -- Two more individual waveforms optionally available1 Two more individual waveforms optionally available1

REGION-OF-INTEREST waveform (RoI) can be varied continuously from
CONSTANT VELOCITY to CONSTANT ACCELERATION (TRIANGLE) mode

1The individual waveforms are stored in EPROMs. They either can be programmed with suitable tools in the electronic laboratory of the customer or optionally purchased from WissEl.
