Cable
Special ZOO ohm cable available
in lengths to meet customer req"Girements.
The input circuit of the Model 460A is a terminated transmission
line with a characteristic impedance of ZOO ohms.
The output circuit has an impedance of Z80 ohms (resistive)o
The
load impedance determines the gain of the amplifiero
Therefore,
it is not necessary to match the load to the output of the amplifier
unless the gain is adversely affected.
Shown below are two dia-
grams for connecting a matched or unmatched load to the Model
460A using a ZOO ohm cable.
