3.3.3.  Sample  rate 
One  of  the  most  important  settings  is  the  sample  rate.  The  sample  rate  defines  how  many  data  points                  
IOLITE®   will   transfer   to   DEWESoft®.   A   higher   sample   rate   also   means   that   more   data   needs   to   be                 
transferred  via  EtherCAT®  to  your  computer. 
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                   
want  to  measure,  e.g.  1  kS/s  for  a  50  Hz  sine-wave.  If  you  have  a  lot  of  high  frequency  components,  it  may                      
be  necessary  to  sample  100  times  faster,  e.g.  5  kS/s  for  the  50  Hz  sine-wave,  or  even  more.  If  you  display                     
only  the  frequency  domain  (FFT  analysis),  a  2.5  times  faster  sampling  would  be  sufficient  (125  S/s  for  the                  
50  Hz  sine-wave).  The  higher  the  sampling  rate,  the  better  the  time  resolution.  But  also  the  file  size  will                   
increase.
