May 2, 2023 - Vista, California - Axiom Test Equipment, Inc., an electronic test equipment rental
and sales company has published a new blog post entitled "How to Test Cables & Antennas Together in 2023" that covers
how testing antennas and cables as an integrated assembly can reveal a great deal
about how they will work together within their system. A variety of measurements
can help characterize antennas with cables and some of the latest test tools can
deliver those measurements when and where needed.
Diverse types of tests, such as frequency domain reflectometry (FDR) or time
domain reflectometry (TDR) measurements, can confirm continuous impedance in a signal
path formed by antennas and cables. These measurements check for reflections coming
along the signal path, using continuous broadband frequency signals in FDR and pulsed
signals in TDR. Test units capable of FDR and TDR measurements can isolate problems
along the antenna/cable signal path, such as loose or worn connectors. Such measurements
can provide information about the distance to a fault with much greater precision
than, for example, from visible inspections along a coaxial cable.
Terrestrial communications, satellite communications (satcom), and radar systems
rely on radios and antennas working together. Radio receivers, transmitters, and
antennas are connected by various kinds of cables, including coaxial cables, and
users count on them maintaining those connections. Breaks in cables, misaligned
connectors, and other faults can degrade performance and must be checked upon antenna,
cable, and system installation and during regular maintenance cycles. Testing antennas
and cables separately can be beneficial but testing them as an integrated assembly
can reveal a great deal about how they will work together within the system. A variety
of measurements can help characterize antennas with cables and some of the latest
test tools can deliver those measurements when and where needed, under battery power
and in compact, portable packages.
Maximum transfer of electromagnetic (EM) energy through antennas and cables to
and from transmitters and receivers requires a signal path with continuous impedance.
Changes or disruptions in a nominal impedance, such as 50 or 75 ?, will cause signal
reflections. A deviation in impedance can come from almost unnoticeable conditions,
such as a loose connector. Diverse types of tests, such as frequency domain reflectometry
(FDR) or time domain reflectometry (TDR) measurements, can confirm continuous impedance
in a signal path formed by antennas and cables. These measurements check for reflections
coming along the signal path, using continuous broadband frequency signals in FDR
and pulsed signals in TDR. EM energy is lost in forward and reverse directions due
to impedance mismatches and can be measured as insertion loss in the forward direction
and return loss in the reverse direction. The right test tools can measure these
losses as well as find faults in the cables or antennas that can cause significant
losses of signal power.
Loss of signal power can result in loss of range in radar systems and loss of
coverage in cellular and wireless communications systems. In high-power systems,
lost signal power is dissipated as heat which can damage and degrade components,
shortening their expected operating lifetimes. Several types of measurements can
avoid antenna/cable interconnection problems during installation and identify faults
during maintenance checks.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
