In your daily work , you should generate and analyze continuous CA  signal sometimes; How could you generate one continuous CA signal by RFmx Waveform Creator ?  And how could you set the RFmx Software Front Panel to demodulate the continuous CA signal ?

Here is NR continuous CA as an example to show you how to setup it ;

1.Open RFmx Waveform Creator to create NR continuous CA signal (5CC*20MHz)
Select the Carrier Allocation and Channel Bandwidth:

2.Setting RFmx NR to demodulate the signal
Setting the basic key parameters:
