Random Noise UserObject, Step 1

Display the noisy waveform and the noise spectrum outside the
UserObject. Provide control outside the UserObject for the
following: amplitude, number of points, interval (time span), DC
offset.
Solution—Random Noise UserObject
Figure 291 shows a solution for the Random Noise
UserObject.
NOTE
Do not use a virtual source inside the UserObject. Use objects such as
Build Waveform and Random to create the UserObject.
