1. The clipped sine is programmed by “AMPlitude” or “Total Harmonic
Distortion”. Programming ranges from 0 to 100% for amplitude
(100%: no clipped sine), and from 0 to 43% for THD (0%: no
distortion).
2. User-defined waveform is defined on a remote PC and downloaded
from it. For detailed of factory DST waveform refer to Appendix B.
WARNING
1. When use user-defined waveform, if the waveform frequency is
over 1000Hz, it might cause AC source damage.
2. Because of the bandwidth limitation of AC source, the output may
distortion. Especially when external V reference consists of high
frequency composition.

4. Press
5 , 0 , then press ENTER Vac = 120.0 F=50.0 Vdc = 0.0
to set F=50.
5. Press
1 , 0 , then press ENTER Vac = 120.0 F=50.0 Vdc = 10.0
