Where A = Amplitude
m = Current point (I..N)
N = Total number of points
t = Time constant set by user
For Negative EXPonential:
F(m) =
For GAUSsian:

For SINC:
F(m) =
N
where R = (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.
