Pulses With Overshoot; Dds Operation And Further Waveform Considerations; Dds Operation - Metrix GX1010 Notice De Fonctionnement

If the trigger parameters have been changed from the above example, re-enter them.

6.4.3. Pulses with Overshoot

The edges and overshoot peaks are sinewaves. The amount of overshoot depends on the
starting phase angle which will be from -89° to about 30°. The Main generator amplitude
determines the amplitude of the peaks;. the amplitude of the flat portions depends on the
PHASE.
Following on from the previous examples:
Set FREQ, 2, 0, kHz
Press EDIT, TRIG to select the Trigger menu
Move the edit cursor to the PHASE field and use the rotary control to adjust the phase
which will vary the amplitude of the flat portion, creating variable overshoot.

DDS Operation and Further Waveform Considerations

This section gives some further information on DDS operation as a background to
understanding both the advantages and limitations of DDS waveform generation.
