F1: FROM - Selects the starting point address.
F2: TO - Selects the ending point address.
F4: EXEC - Displays the Confirmation menu, F1:NO and F3:YES
Confirmation Menu
F3: PREDEF - (Predefined Waveforms) Selects one of the predefined waveforms: Sine, Triangle, Square
and Noise. Displays the Predefined waveforms menu:
Predefine Menu
F1: TYPE - Selects the waveform Sine, Triangle, Square, Noise, Ramp up, Ramp down,
exponential, Sin(x)/x, and Gaussian distribution. If Noise function is selected, a submenu is
displayed to allow adding the noise to an available waveform or to generate it as a new noise
waveform.
F2: FROM DATA - Selects the starting point of the generated waveform and data value.
F3: LENG/SCALE - Selects the length of the predefined waveform (number of points for a full
wave). The length value must be a number that is divisible by 4 or by 2
in some instances. If not, a pop up message will say “Must divide by 4” or
“Must divide by 2” and entered values will change back to its original.
Different waveforms have different limitations on the length. Refer to
Table 3-1 below. If scale is too high, a message will display “Scale too
high.”

F3: SCALE - Selects the scale factor of the waveform. 100% means that the waveform
spans the full scale of -8191 to 8191. Scale factors are limited by the point data
