44478A Wiring Information
External Wiring The figure below shows the module’s female BNC
connectors and the channel group numbers. The BNC connectors accept
user-supplied male BNC connectors.
Terminations The figure on page 268 shows the SMB connectors on the
main PC Board. The SMB connectors allow you to connect SMB resistive
terminations to any unused channels. SMB resistive terminations are
available from Agilent using the following part number:
•
34585A (set of four 50
Ω
terminations for the 44478A)
•
34586A (set of four 75
Ω
terminations for the 44478B)
Note
To maintain proper operation, unused channels should be terminated by
plugging a 50
Ω
or 75
Ω
SMB type resistive termination (50
Ω
for 44478A
and 75
Ω
for 44478B) onto the male SMB connector provided for each
channel.
