Steve Kawamura, Sound and Vibration Specialist at HBK, explores the most common frustrations engineers face — from complex software and mismatched tools to wasted hours on compatibility checks — and explains how the Troubleshooting Analyser bundle removes that complexity with a single, scalable solution. Perfect for companies looking to save time, reduce costs, and get accurate results from day one.
Sound and vibration testing doesn't have to be complicated – but simple mistakes during setup can derail your entire test programme.
Avoiding these six common errors will save time, prevent invalid data, and reduce costly rework.
All analysis systems need information on how to power a transducer, and how to convert the transducer's electrical signal into engineering units for the signal analysis calculations. Entering this information incorrectly, such as putting a decimal in the wrong place for a transducer Sensitivity value, can ruin your data.
How HBK solves it: HBK's Fusion-LN and LAN-XI data acquisition systems support TEDS technology, which recognises transducer and configures the system accordingly. The system reads the transducer's built-in memory chip and automatically configures settings and parameters.
The result: Capture accurate data from your first measurement without configuration errors.
Transducers and cables can become damaged thru mishandling. A damaged sensor continues generating plausible-looking numbers that bear no relation to reality, while deteriorated cables inject spurious signals that appear as legitimate data.
How HBK solves it: HBK's BK Connect analysis software includes built-in verification tools that check your entire signal chain before you start testing. Detect cable faults, identify damaged transducers, and verify measurement accuracy.
The result: Confirm system integrity in minutes, not after hours of questionable data.
For example, steady-state analysis identifies continuous hums effectively but cannot detect transient impacts. Time recording captures when noise and vibration events occur without revealing the underlying frequencies responsible.
How HBK solves it: BK Connect software bundle includes multiple analysis types in one comprehensive package – FFT, octave analysis, time recording, and order tracking. The software's guided workflows help you select the appropriate analysis method for your specific problem.
The result: Apply the right analysis method to reveal the actual problem.
When first using S&V testing software, engineers often assume they need to customise every parameter before making their first measurement. The result: hours of unnecessary setup and an increased chance of configuration errors.
How HBK solves it: BK Connect is designed with intelligent defaults and guided workflows that handle most measurement scenarios. The software's intuitive interface guides you through setup logically, highlighting the parameters most relevant to your test.
The result: Make meaningful measurements within hours without convoluted setups.
Engineers new to S&V testing often recreate configurations for each measurement session, unaware that setups can be saved and reused. Most engineering work involves repetitive testing. Without saved configurations, teams waste time and introduce inconsistency between measurements.
How HBK solves it: BK Connect makes it easy to save your complete test configuration as reusable templates. Test electric motors regularly? Save that setup. HBK's system preserves transducer assignments, analysis parameters, and display settings.
The result: Make valid comparisons while saving hours on repeated tests.
You've identified a vibration issue, made a design change, and retested the system. But without the ability to directly compare before-and-after results, how do you know if you've fixed the issue at hand? Many engineers end up eyeballing printouts or trying to remember what the previous plot looked like.
How HBK solves it: BK Connect includes powerful comparison tools that let you overlay results from different test runs directly. The software provides clear before-and-after analysis with full export to Word, Excel, and PowerPoint for reporting.
The result: Transform subjective observations into quantified engineering decisions.
These mistakes aren't inevitable – they're preventable with the right strategy and tools.
HBK's Troubleshooting Analyser – a complete plug-and-play solution combining BK Connect analysis software with either Fusion-LN or LAN-XI data acquisition hardware – eliminates these challenges from the outset.
The system delivers automatic transducer recognition, built-in verification, comprehensive analysis options, intuitive workflows, template management, and powerful comparison capabilities.

There are a few features that make a quality analysis solution more reliable and easier to use:
The troubleshooting analyser is perfect for teams that are just starting to explore sound and vibration (S&V) analysis, for a few reasons:
The Troubleshooting Analyser is a fully integrated, plug-and-play solution.
Each component – BK Connect software and Fusion-LN or LAN-XI hardware – is designed to work seamlessly together out of the box. That means there’s no need to worry about figuring out how to make your analysis software talk to your DAQ system.
Buying the full Troubleshooting Analyser also means you get one integrated purchase. One support contract. One trusted partner.
The Troubleshooting Analyser is designed to make setup as simple as possible.
The Fusion-LN or LAN-XI data acquisition system is built to integrate seamlessly with BK Connect. Your hardware can be connected instantly to your computer using a normal Ethernet cable, and work instantly with your data acquisition hardware – giving you more complete, reliable, detailed measurements from day one.
Exactly how long the setup takes depends on your level of experience.
If you are new to sound and vibration testing, we recommend starting your setup with an HBK Application Engineer, who can join you remotely or on-site. These field experts will guide you through the setup process and help you ensure that your system is working as it should.
Even this detailed training can usually be completed in three hours or less. That’s three hours to get you completely familiar with the solution and ready to start testing and measurement.
The process can be even shorter for users familiar with S&V. Using the BK Connect software itself can take just a few minutes if you already understand the process of setting up and running S&V tests.
The Troubleshooting Analyser is made up of two parts: the robust and precise Fusion-LN DAQ system (or, for some specific applications, the older LAN-XI) and BK Connect, our comprehensive and flexible sound and vibration engineering software.
The two parts of the solution integrate effortlessly, supporting the entire process of S&V troubleshooting and making it easier to gather and act upon precise, accurate S&V data.
Yes! The Troubleshooting Analyser is designed to get you started with S&V testing quickly and easily, then allow you to evolve or upscale your capability as your needs change.
Simply start with BK Connect and Fusion-LN (or, in some cases, LAN-XI) and add new BK Connect modules as and when you need them.
Your BK Connect license includes our most commonly-used modules, plus any other modules that your dedicated Application Engineering support team thinks would be right for your needs.
Later, you might find that the BK Connect modal analysis module and the noise source identification module are both extremely useful as your S&V testing abilities and setup become more complex.
By using the Troubleshooting Analyser, you can add these extra modules under the same license – making it easy to add the functionality you need without overcomplicating your billing or setup process.
The Troubleshooting Analyser is designed to be compatible with common data files, including WAV time recordings and Universal File Formats (UFF).
This makes it much easier to integrate the Troubleshooting Analyser into your existing workflows without ripping out your entire system and replacing it from scratch.
The Troubleshooting Analyser is perfect for innovative companies in any industry in which precision and quality engineering are essential.
At HBK, we’ve helped to implement Fusion-LN, LAN-XI, and BK Connect in a wide range of industries – including the consumer goods, automotive, aerospace and defence, energy, and academic research industries.
In these industries, the Troubleshooting Analyser can be used to diagnose and solve S&V problems from day one, making it ideal for use in:
