amplitude. Therefore, a value of 8191 corresponds to positive peak amplitude, 0 corresponds to the waveform offset, and -
8191 corresponds to the negative peak amplitude.
F1: POINT - This menu allows point by point waveform editing. When selected, the following menu is displayed:
F1: ADRS - Select the current address in the arbitrary waveform memory.
F2: DATA - Selects the data point value at the current address. You can change the point
value from -8191 to 8191.
F5: PREV - Goes back to previous menu (Edit menu).
F2: LINE - This menu allows a line drawing between two selected points.
Displays the following menu:
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
F5: PREV - Goes back to previous menu (Edit menu).
F3: PREDEF - (Predefined Waveforms) Selects one of the predefined waveforms
F1: TYPE - Selects the waveform Sine, Triangle, Square, Noise, Ramp up, Ramp down, exponential up,
exponential down, Sin(x)/x, and Gaussian distribution. If Noise function is selected, a submenu is displayed
when F5:EXEC is pressed 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 its data value.
F3: LENG - 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.
F4: SCALE - Selects the scale of the waveform. If scale is too high, a message will display
“Scale too high.” 100% means that the waveform spans the full scale of -8191 to
8191. Scale factors are limited by the point data value of the starting point and
automatically calculated by the unit.
Wave Minimum Length Divisible by
Sine 16 4
Triangle 16 4
Square 2 2
Noise 16 1

F5: EXEC - Prompts you to confirm whether to execute the selected predefined waveform. Press NO to
