About Bit Error Rate Testing

A method of evaluating the performance of a digital communication system, Bit Error Rate (BER) testing measures how many bit errors occur within a period. This allows users to evaluate how reliable the system is and to identify areas for improvement. BER testing is often used in telecommunications testing and troubleshooting because even minimal errors can have significant impacts on the transfer of data.  

A Bit Error Rate Tester (BERT) works by sending a specific data sequence through a system. This original data pattern is compared to the one received, and the difference between the two indicates the number of bit errors. The BER is the ratio of the number of bit errors to the total number of bits that were transmitted.  

A BERT may be used in a range of different industries and applications. For example, BER testers are used to monitor and troubleshoot telecommunications networks and ensure the reliability of communications systems in aerospace and defense. BER tests are also used in automotive and medical fields.


Frequently Asked Questions 

What's the difference between Bit Error Rate Test and arbitrary waveform generation? 

Both used in testing digital communications systems, bit error rate testing and arbitrary waveform generation are two types of testing. BERT is used to test error rates in systems under different conditions such as varying noise levels and signals and frequencies. BER testers do this by generating a data pattern and sending it through a system, then comparing the original pattern to the one received to evaluate the difference. Arbitrary waveform generators, on the other hand, create waveforms with specific characteristics to mimic real-world signals for testing purposes.  

How do I calculate BER? 

To calculate BER, divide the number of bit errors by the total number of bits transmitted. Then, multiply this number by 100 to get a percentage.    

What is an acceptable BER? 

The maximum acceptable BER varies considerably between different industries, applications, and communication systems. In general, 10-9 is considered acceptable for most telecommunication systems, but 10-13 or better is more appropriate for data transmission. 

What are the best BERT manufacturers? 

All the bit error rate testers available from Electro Rent are carefully selected to ensure their quality. Leading BERT manufacturers include Keysight Technologies, Anritsu, Tektronix, Synthesys, Quantifi Photonics, GW Instek, and Hyperlabs.  

What should I consider when choosing a BERT? 

When choosing equipment to test bit error rate in your communications systems, a few key points to think about include: 

  • Configurability: Can the BERT be configured with different modulation schemes, data patterns, and signal levels to meet your needs? 
  • Signal quality: How precisely does the device create the required signal and is there jitter or noise which will reduce the accuracy of your measurement? 
  • Compatibility: Is the BERT compatible with your current equipment? 
  • Budget: Is the price right? Should I consider renting or buying used, or look for a different financial solution
  • User-friendliness: Is it easy and intuitive to use? 
  • Vendor support: Does the vendor offer technical support with your purchase? 

Why rent bit error rate testers? 

BERT rental is a cost-effective and flexible alternative to buying test equipment. Allowing you to access instruments for short or long-term testing, our flexible rental solutions allow you to adjust, extend, or stop your rental period with ease. Renting frees up your budget while allowing you to access top-of-the-range tools for testing at a fraction of the price. What’s more, there's no need to worry about obsolescence or maintenance; renting means you're never burdened with aging assets.  

Is it better to buy a used bit error rate tester? 

Buying a used BERT from a trusted supplier allows you to access top-quality equipment from leading manufacturers at a fraction of the normal price. All our Certified Pre-Owned bit error rate testers are carefully checked and calibrated in our labs as part of the rigorous 23-step certification process which ensures your equipment is as accurate and dependable as if it were new.  

Choosing whether to rent equipment or buy used can be a difficult decision, so feel free to contact our knowledgeable team who will help you assess your requirements and find the best solution. Alternatively, download our free whitepaper Rent or Buy? Why Equipment Rental is the Strategic Choice to learn more.
