Specifications and Characteristics
Characteristic Performance
N4431D (3.5 mm)
The characteristic performance in the following table applies to N4431D 
Option 010 (3.5 mm female connectors on all ports). The data describes 
performance when measuring “thru path” A-B, C-D, A–D, A-D, B–C, and B-D. 
N4431D (4.3-10)
The characteristic performance in the following table applies to N4431D (if any 
of the ports consist of 4.3-10 connector). The data describes performance 
when measuring “thru path” A-B, C-D, A–D, A-D, B–C, and B-D.
