Dual Arbitrary Waveform Generator

Using the Dual ARB Waveform Player

The dual arbitrary (ARB) waveform player is used to edit and play waveform files. There are two types of waveform files: segments (WFM1) and sequences (SEQ). A segments is an individual waveform that is defined using an installed ARB format, such as Two Tone, and created using the internal arbitrary waveform generator. A sequences is several individual segments strung together in one file. Waveform files can also be created remotely and downloaded to the PSG for playback as a segment. For information on downloading waveforms, refer to the Programming Guide.

A waveform is generated when an ARB modulation format is turned on, and is named

AUTOGEN_WAVEFORM. Because this default file name is shared among all ARB formats, if the file is not renamed in the dual ARB player after turning the modulation format off, it is overwritten when the same or another ARB format is turned on.

Waveform player features include waveform clipping, markers, and triggering. Clipping allows you to reduce high power peaks, which can cause adjacent channel noise. Markers and triggering are useful for synchronizing the output of the signal generator with other devices.

Before you can work with a waveform file, it must reside in volatile memory. A newly generated segment file (AUTOGEN_WAVEFORM) initially resides in volatile memory until you store it to non-volatile memory. Whenever you cycle the power on the PSG or download new firmware, you must reload your waveform file from non-volatile memory.

Accessing the Dual ARB Player
