User channels store a single value. You can use user channels as variables in procedures, stimulus profiles, and so on. User channels are especially useful when mapped to other channels. For example, you can use a single user channel to start multiple models simultaneously by mapping the user channel to the Model Command channel of each model. You can use this technique for triggering, dynamically changing a value in a real-time sequence, and so on.

Calculated channels produce a new value based on calculations performed on other channels in the system.
