6.7 Compression and Extension of Waveform - 1
This section explains how to create a burst waveform by contracting the sine wave to the first quarter
of the waveform display screen, as a sample of horizontally contracting/extending a waveform.
Step 1: Click the button at the top left of the screen.
A sine wave is selected in the initial status.
Change the numerical value to the right of [Period] from [1] to [4] to make a sine
wave with four cycles.
Click the All Page OK
button to return to the waveform display screen.
Step 2: Click the button at the top left of the screen. The same result can be obtained when
[Tool] - [Compress/Decompress] is selected.
The screen titled [ARB - Compress/Decompress] appears.
Step 3: When the memory size is 8 KW, [8192.000Word] is displayed to the right bottom of
the waveform display screen.
Leave the number area to the right of [Start X=] as [0].
Set the quarter of memory size, [2048] in the number area to the right of [End X=]
and press the
Enter key.
The four sine waves displayed across the waveform are contracted to the first quarter
on the waveform display screen.
If the waveform is hidden behind the contraction/extraction screen and difficult to
see, move the screen.
Step 4: Click the OK button to return to the waveform display screen.
Explanation 1: [Start Point(S) X=] is left as [0] in this example, so the original waveform is
contracted to the first quarter of waveform on the waveform display screen.
For example, when [Start Point(S) X=] is set to [2048] and [End Point(E) X=] is
set to [4096], the original waveform is contracted to the second quarter on the
waveform display screen.
Explanation 2: It is also possible to specify the whole waveform.
Select a part of waveform on the waveform display screen with markers A and B in
advance.
If the
Fit Length button is then clicked on the contraction/extraction screen, the
selected range is extended to the whole waveform.
