A 50-Ω termination resistor is needed for the network analyzer.
Figure 7. Test Circuit for Off Isolation (O
IRR
)
OFF isolation is measured at the output of the OFF channel. For example, when V
S
= V
CC
, V
E
= 0, and YA is the input,
the output is measured at IA
0
. All unused analog input (Y) ports are left open and output (I) ports are connected to
GND through 50-Ω pulldown resistors.
