Dear Sir,
If you need to use two CWPulse components you will not be able to set a finite number of pulses to be generated. When you set the component to produce a finite number of pulses, it actually uses two counters to perform the operation. One is used to generate the pulses and the other one is used to count the pulses that are generated. You can use multiple CWPulse components as long as the pulse type is set to continuous on both components.
