Figure 3-60: Waveform generated by the Example 2 equation

The following example creates one sequence file and four waveforms.

delete(”test.seq”)

size=512

clock=1e9

num=4

’write sequence file header

write(”test.seq”,”3002\n”)

write(”test.seq”,”LINES ”:num:”\n”)

for i = 1 to num

’create a waveform file

”test”:i:”.wfm” = sin(2 * pi * i * scale)

’add line to sequence file

rep = num * i

write(”test.seq”,”\”test”:i:”.wfm\”,\”\”,”:rep:”\n”)

The first line is the statement for deleting the existing waveform. If that file does

not exist, then no action is taken.

The size and clock keywords are the system valuables representing the waveform

record length, in points, and the sampling clock frequency. They are set

to 512 points and 1.0 GS/s in the above example.

The comment text on line 5 starts with a single quotation (’) character. Comment

text is effective until the end of the line containing the single-quote character.
