As you adapt these examples, be aware of variations:
- The number of vectors used is arbitrary. A larger number improves resolution. The
number of vectors is used to determine "Delta" and count the number of loops.
Adjust the loop counter range as needed to avoid division by zero as in the sine(xl/x
example.
- Modify "Scale_factor" so waveform amplitude fits in the 3314A AMPTD setting.
- After generating a waveform, you may need to adjust V HGTs at the waveform
endpoints and PHASE to improve closure. You can modify FREQ, AMPTD, and OFF-
SET to change other characteristics.
