Frequently Asked Questions 

1. How do cable and antenna analysers 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 is able to measure 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.  
2. What are the best cable and antenna analysers? 
   While the best analysers 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.  
3. What factors should I consider when choosing a cable and antenna analyser?  
   Some key features to consider include: 
   • Frequency range: The analyser must cover the range of frequencies that you are testing. While most cable and antenna analysers cover the typical range of frequencies used in telecommunications, handheld analysers 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 analysers can make highly accurate measurements immediately, some might need to warm up first.
   • Portability: If you want to use your analyser for testing and measurement in the field, it's important that you choose a handheld analyser that can be easily transported to test sites. Size, weight and battery life are all key considerations.
   • Data storage: The analyser's data capacity determines how much information can be collected and stored after testing.
4. What is the typical frequency range covered by cable and antenna analyzers?
   Cable and antenna analyzers typically range from a few kHz to several GHz, with portable models usually up to 6 GHz. Benchtop units could handle even higher frequencies for microwave testing or satellite communications.
5. What measurement parameters can cable and antenna analyzers test?
   In addition to VSWR (Voltage Standing Wave Ratio) and Return Loss, today’s analyzers can also evaluate cable loss, Distance-To-Fault (DTF), length-to-fault, phase, and even complex reflection measurements for Signal Integrity testing in high-speed cables, antennas, and transmission lines.
6. How accurate are the measurements from cable and antenna analyzers?
   Accuracy is very important for accurate fault detection. Most analyzers provide better than ±0.1 dB accuracy in return loss and VSWR. But as we know the accuracy could be a frequency-specific issue so you have to ensure that the analyzer you choose meets your testing needs over the desired frequencies.
7. Can cable and antenna analyzers perform distance-to-fault (DTF) testing?
   Yes, most analyzers today have a DTF feature, to help you find where an anomaly exists on a cable or antenna. It can assist in finding broken or snapped cables, if the mis-alignment is linked to the connections at each end.
8. How portable are handheld cable and antenna analyzers?
   Portable analyzers deployed in the field are typically lightweight and battery operated. Look for long battery life (4-8 hours), tough cases and a small form factor, perfect for installations in the field or when testing outdoors.
9. Can cable and antenna analyzers generate reports or store measurement data?
   Most current day analyzers have data logging and report generation features where the measurements are saved on internal memory, SD cards or USB drives. You can easily copy results for documentation, analysis, and record-keeping.
10. Are there any advanced features like GPS or Wi-Fi connectivity available in some models?
    Some premium models can also be connected with a smartphone or tablet via Wi-Fi for control and even data transfer. Others could use GPS-synced for Site Survey and network deployment.
11. Is there any software for advanced analysis or remote monitoring of cable and antenna analyzers?
    Yes, most analyzers are bundled with PC software or supported to connect with LabView, Python or other platforms, for remote control, process automation, telemetry, data acquisition, analysis and presentation. These features are valuable for automation or for deploying massive numbers of networks.
12. Should I rent or buy an antenna and cable analyser?
    The choice of whether to rent or buy test equipment depends on your project requirements and budget. Buying certified pre-owned analysers 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. Don't forget that we also offer a range of flexible financial solutions such as hire purchase, operating leases, and more to ensure there's an option that works for you.
