ATT 

The  ATT  submenu  allows  selecting  the  internal  attenuators.  Current  internal 

attenuation  is  displayed  at  this  menu  and  on  the  right  side  under  the  graph.  Any 
additional attenuation raises the noise floor but allows to input stronger signals (i.e. 
raises the reference level). The internal attenuation can be adjusted in 5 dB steps by 
using the buttons. The internal attenuation is 0 by default.  

To exit the ATT submenu and return to the LEVEL menu, tap BACK. 

2.7.3

 

LNA 

Tapping the LNA button turns on and off the “Low Noise Amplification”. LNA lowers 

the noise floor and allows viewing very weak signals but the reference (overload) level 
is considerably lowered. 

When LNA is enabled, the LNA button is 

green

 and an indication is displayed under 

the graph. LNA is disabled by default. 

 

 

To get best results with the LNA, set internal attenuation ATT to zero and lower 
reference level at the REF menu.

 

 

Entering the REF menu 

The REF menu
