24 Configuring the RF Multiplexers
Chapter 2
Connecting User Inputs to E1472A/E1473A
User inputs to the E1472A RF Multiplexer and E1473A Expander modules
are via user-supplied female 50 Ohm SMB connectors to the male 50 Ohm
SMB connectors on the modules. Figure 2-5 shows the RF Multiplexer 50
Ohm SMB connectors and associated channel numbers.
Cabling Guidelines
•
For best high-frequency performance, user cabling should have at
least two braided shields or one braid and a foil wrap.
•
Always use shielded coaxial cables with the characteristic
impedance of 50 Ohms. Keep cables as short as possible,
especially in high-frequency circuits or pulse circuits where a
rise/fall time is critical.
•
Long cables can add delay time which can cause timing problems.
All test equipment, such as counters, spectrum analyzers, and
oscilloscopes must be terminated in the characteristic impedance
(50 Ohms) to minimize reflection loss.
