Using the Dual ARB Waveform Player

Using the Dual ARB Waveform Player

The dual arbitrary (ARB) waveform player is used to create, edit, and play waveform files. There are two types of waveform files: segments and sequences. A segment is a waveform file that is created using one of the signal generator’s pre- defined ARB formats. A sequence can be described as several segments strung together to create one waveform file. Waveform files can also be created remotely using another signal generator or using computer programs and downloaded to the PSG for playback by the Dual ARB waveform player. For information on downloading waveforms, refer to the E8257D/67D PSG Signal Generators Programming Guide.

A waveform file is automatically generated whenever an ARB modulation format is turned on. This automatically generated file is named AUTOGEN_WAVEFORM. Because this default file name is shared among all ARB formats, it must be renamed if you want to save the information. If the file is not renamed, it will be overwritten when another ARB format is turned on.

The Dual ARB waveform player provides markers (page 88), triggering (page 102), and clipping (page 108) capabilities.

Before you can work with any waveform file, it must reside in volatile memory. The signal generator has two types of memory, WFM1 (volatile waveform memory) and NVWFM (non- volatile waveform memory). A newly generated waveform file (AUTOGEN_WAVEFORM), created when the Arb Waveform Generator is turned on, initially resides in WFM1. If you want to save this file, rename it and store it in NVWFM. Load a stored waveform file from NVWFM into volatile memory (WFM1) where it can be edited or played by the ARB waveform player. Refer to “Custom Modulation” on page 71 for more information.
