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.

Digital function generator model	DFG-500	DFG-1000	DFG-1200
Generated output waveforms	Sine Triangle (constant acceleration)	Sine Triangle (constant acceleration) Slopes (5% - 10% - 20% and 40%)	Sine Triangle (constant acceleration) Slopes (5% - 10% - 20% and 40%) REGION-OF-INTEREST waveform (RoI)
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.
