Model 350A400 

Rev B 

33 

4.3.7 

Low or No Power Output (RF Test) (Schematic Diagram Nos. 
10044770 and 10039874) 

NOTE:  The DC Tests specified in Section 4.3.8 should be completed before conducting the RF tests specified 

in the following sections. 

1.

 

The Model 350A400’s typical gain response at -20 dBm input and 0 dBm input is shown in Figure 4-1 
and Figure 4-2.  The actual gain may vary considerably from that shown in Figure 4-1 but should 

be ≥ 

55.5 dBm at 0dBm input.
