Arbitrary Waveform Composer

DATA FILE FORMAT AWC data is saved as ASCII text. Each line of the file consists of a single
numerical value followed by a carriage return/linefeed. The first line is the
number of data points in the waveform. The second line is the sampling
frequency in Hz. The third line is the trigger source, and the fourth line the
internal trigger rate. The remainder of the lines are the waveform amplitude
points. There is one line for each point. There must be a minimum of 8 points
and a maximum of 16,300 points for each waveform. The value of the data is
the waveform amplitude in
volts at that data point. Sample files with extension
.txt are included with the AWC program distribution.
FOR MORE INFO Be sure to read the readme.txt file included in the AWC zip file for any changes
in the software. Some examples of waveform files (e.g., sample1.txt) are also
included for reference.
