The equations used for generating EXPonential, GAUSian and
SINC functions are as follows:
For Positive EXPonential:
Where A = Amplitude
m = Current point (I..N)
N = Total number of points
t = Time constant set by user
For Negative EXPonential:
For GAUSsian:
For SINC:
where R = N (number of points per cycle)
___
cyc
cyc = Number of cycles of SINC
The standard waveform will be available at the output connector
only after the FUNC:MODE FIX command has been executed.
Select the FUNC:SHAP PULS command. Parameters for the
PULSe function shape can now be modified and will cause an effect
on the output waveform. Note that changes made to parameters for
a specific function do not have any effect on other functions.
