Dual Arbitrary Waveform Generator
Using the Dual ARB Waveform Player
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
Press Mode > Dual ARB.
You are now at the first-level softkey menu as shown in the following figure. Most procedures after the
procedure “Creating the First Waveform Segment” on page 100 start from this first-level softkey menu.
