User Manual California Instruments 4.4 Waveform Management The CSW Series employs independent arbitrary waveform generators for each phase. This allows the user to create custom waveforms. In addition, the CSW offers three standard waveforms that are always available. This chapter covers issues that relate to defining, downloading and managing custom waveforms. 4.4.1 Standard Waveforms For many AC applications, a sine wave shape is used.
PAGE 84
User Manual California Instruments 4.4.3 Creating Custom Waveforms The CSW Series provides four groups of 50 custom defined waveforms each for a total of 200 waveforms in addition to the 3 standard waveforms. Of these four groups, one may be active at a time. The active group is selected in the INITIAL SETUP menu. Custom waveforms cannot be created from the front panel of the CSW Series. Rather, they have to be downloaded through the IEEE-488 or RS232C interface.

To activate your new selection, YOU MUST CYCLE THE POWER so the AC source reinitializes.
PAGE 86
User Manual California Instruments 4.4.6 Frequency Response Restrictions The user may create a waveform that contains any number of harmonic frequencies of the fundamental. The AC Source itself however has a finite signal bandwidth and will attenuate higher frequency components of the signal. To limit the maximum frequency component of the output signal, the CSW controller automatically applies a band-pass filter to all custom waveforms as they are downloaded.
