2.  Reference level 
The reference level, input attenuation, preamplifier and maximum mixing 
level maintain coupling relationships. Refer to the introduction of equation 
(2-3) in “Ref Level” for more details. 
 
3.  Input Attenuation 
The input attenuation, reference level, preamplifier and maximum mixing 
level maintain coupling relationships. Refer to the introduction of equation 
(2-3) in “Ref Level” for more details.  
 
4.  RBW 
This parameter maintains a coupling relationship with the span. Refer to “RBW” 
for more details.  
 
5.  VBW 
This parameter maintains a coupling relationship with RBW. Refer to “VBW” 
for more details.  
 
6.  Sweep Time 
The sweep time, RBW, VBW and span maintain coupling relationships. Refer 
to “BW/Det” for more details.
