DFG-1000
 Digital Function Generator

The Digital Function Generator DFG-1000 provides the Mössbauer Driving System with the reference signal, which determines the waveform of the source motion. The signal is generated digitally. This results in a source motion, which is completely synchronous to the channel sweep of the multichannel analyser.

DFG-1000 provides eight waveforms:

SINE

TRIANGLE (CONSTANT ACCELERATION)

CONSTANT VELOCITY (with 5 - 10 - 20 and 40% slope)

F1, F2 (individual , optional waveforms)

In the CONSTANT VELOCITY mode the output signal has selectable sinusoidal slopes for a minimum of vibration disturbance (c.f. figure)
