How do cable and antenna analyzers work? 

Cable and antenna analysers are connected to the antenna or transmission line under test using an adaptor or connector. By transmitting a signal through the antenna or cable under test, the instrument measures parameters such as voltage standing wave ratio (VSWR), return loss, cable loss, and distance-to-fault. The results of the test can be compared to expected values to identify faults or problems.  

What are the best cable and antenna analyzers? 

While the best analyzers for you will depend on your exact specifications and budget, it's fair to say that leading brands such as Anritsu, VIAVI, Keysight Technologies, and Rohde & Schwarz offer some of the world's best analysers.  

What factors should I consider when choosing a cable and antenna analyzer?  

Some key features to consider include: 

• Frequency range: The analyzer must cover the range of frequencies that you are testing. While most cable and antenna analyzers cover the typical range of frequencies used in telecommunications, handheld analyzers usually have a range of a few kHz or MHz to several Ghz, while benchtop versions can often cover higher frequencies.  
• Accuracy of measurements: A high level of accuracy is key for reliable and valid results. While many modern cable and antenna analyzers can make highly accurate measurements immediately, some might need to warm up first.  
• Portability: If you want to use your analyzer for testing and measurement in the field, it's important that you choose a handheld analyzer that can be easily transported to test sites. Size, weight, and battery life are all key considerations. 
• Data storage: The analyzer's data capacity determines how much information can be collected and stored after testing.  

Should I rent or buy an antenna and cable analyzer?  

The choice of whether to rent or buy test equipment depends on your project requirements and budget. Buying certified pre-owned analyzers is a great way to save money on as-good-as-new equipment with expert technical support from the Electro Rent team. For shorter projects, or if you're not sure what equipment you'll need, renting can be a more flexible and cost-effective option. We also offer a range of flexible financial solutions such as purchase, operating leases, and more to ensure there's an option that works for you.
