TableD-3: Lorentz pulse
File name LORENTZ_P.WFM Made with equation editor
Equation size = 1024
clock = 1e9
’pulse width k0 = 20e-9
’peak location k1 = 512e-9
“lorentz.wfm” = 1 / (1+(2*(time - k1) / k0) ^ 2)
Descriptions When the pulse width is taken to be tw50, the waveform can be
expressed by the following formula:

File name SINC.WFM Made with equation editor
Equation size = 2048
clock = 1e9
’sine frequency k0 = 50e6
’peak location k1 = 1024e-9
“sinc.wfm” = sinc(2 * pi * k0 * (time - k1))
Descriptions In general, this waveform is expressed by the following formula:
This is the impulse response for the ideal low pass filter for the
frequency bandwidth f. At least 42 periods are required to use a
vertical resolution of 8 bits.
