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
Keysight
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 (
), triggering
(
), and clipping (
) 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 for more information.
