First, you need to extract the pulse.
1. Open the acquired waveform by waveform editor.
2. Locate the pulse which you want to extract, then move the left–cursor to the
center of pulse.
3. Expand the display by using Zoom function as necessary.
4. Specify the range of pulse you want to extract.
After specifying the range, check the number of points that make up the PW50.
Set the total number of points to eight times of PW50(in this case, the PW50 is
set to 50%).
5. Locate the left–cursor to 0, the right–cursor to 1 point left of the pulse you
want to extract. Then, delete unnecessary data on the left side of the pulse by
using Operation (bottom) ! Cut (pop–up).
6. Locate the right–cursor to the maximum point of the waveform, the
left–cursor to 1 point right of the pulse you want to extract. Then, delete
unnecessary data on the right side of the pulse by using Operation (bottom)
! Cut (pop–up).
This completes the extraction of pulse you want to create.
Next, you need to adjust the total number of points.
7. Check the number of points that make up the PW50 you extracted(acq_pw).
8. Check the total number of points that make up the extracted pulse(acq_size).
9. Check the value given by Samples/Cell parameter(cells).
10. Specify the total number of points that make up the isolated waveform you
want to create(size).
Use the following formula when PW50 is 50%.
pw = cells/2
size = (pw/acq_pw) * acq_size
11. Press Tools (bottom) ! Re–Sampling (pop–up) to open menu.
12. Specify the value of size calculated by New Points and press OK (side)
button.
Now you have got the isolated waveform.
13. Save the isolated waveform you created by using appropriate name.
This completes the creation of user-defined isolated waveform.
