Chapter 3 Using HP BenchLink/Arb
About Arbitrary Waveforms
Because of this relative amplitude scaling, it is possible to create |
| |
waveforms that contain unintentional dc offsets. Consider a square wave |
| |
that ranges from +1 to |
| |
generator with a specified output voltage of 1 V |
| |
wave will not be centered around 0 V but will have an apparent +0.5 Volt |
| |
dc offset. The +1 relative amplitude will be scaled to +0.75 V and the | 3 | |
relative amplitude will be scaled to | ||
| ||
Where possible, your waveforms should range from +1 to |
| |
| ||
waveform edit window. HP BenchLink/Arb contains a special function to |
| |
allow you expand the Y values to the maximum. |
| |
The Y values of the starting and ending points in your waveform can also |
| |
cause unexpected discontinuities if they are not the same value. The |
| |
function generator output will ‘jump’ from the ending value to the |
| |
starting value each cycle. For a smooth waveform output, be sure the |
| |
starting and ending values are the same. |
| |
Small discontinuities within the waveform can be removed by smoothing |
| |
the waveform. These discontinuities are common with waveforms created |
| |
by freehand or line drawing modes. HP BenchLink/Arb provides a special |
| |
smoothing function for this purpose. |
