One of the most important settings is the sample rate. The sample rate defines how many data points                  
SIRIUS will transfer to the Dewesoft. Higher sample rate also means that more data needs to be                 

The sampling speed mainly depends on your application. To display your signal in a time domain with a                  
good time resolution, you should sample 10 to 20 times faster than the frequency of the signal that you                   
