Description
-----------
 
    Average power spectrum for each string (0-39) and scope (1,2)

    Each power spectrum has 3001 bins (=KPULSE_POWER_SPECT_LEN). 
    
    The power spectrum are arranged as:
    
    String 0, Scope 1
    String 0, Scope 2
    String 1, Scope 1
    String 1, Scope 2
    .
    . 
    .
    String 38, Scope 1
    String 38, Scope 2
    String 39, Scope 1
    String 39, Scope 2

    Therefore, bin C of the average power spectrum for Scope N on 
    String S is given by 
  
    (N * 2 + (S-1)) * KPULSE_POWER_SPECT_LEN + C
   
    The range of frequency is 0 to 500 MHz (=1/(2.*1 ns))
