BERTs are modular instruments consisting of a pattern generator, an error detector or analyzer, and a clock data recovery module. Used across a wide range of applications — including data center interconnects, optical transceivers, high-speed memory interfaces, and next-generation serial buses — Keysight BERTs support critical standards including PCIe®, DDR, USB, and Ethernet (100G / 400G / 800G / 1.6T). Choose from one of our most popular BERT configurations based on supported data rates and line coding or configure one specific to your application needs
Keysight modular digitizers are high-performance signal acquisition instruments designed for fast, precise waveform capture in automated test and measurement systems. Built on PXIe and AXIe, they offer fast sampling rates and wide bandwidths in a compact form factor making them ideal for complex test environments in aerospace and defense, communications, and semiconductor testing.
Keysight data acquisition (DAQ) systems are designed to accurately capture and digitize electrical and physical signals such as voltage, current, temperature, and pressure from real-world environments. Used across industries like aerospace, automotive, energy, and electronics manufacturing, these systems support a wide range of applications, including sensor validation, environmental monitoring, and functional testing. Their modular design and channel scalability make them adaptable to everything from small benchtop setups to large-scale automated test systems. With high accuracy, reliability, and easy integration, Keysight DAQs ensure performance, quality, and efficiency in both R&D and production testing.
With over 30 plug-in modules—including low-frequency, RF, and microwave switching up to 26.5 GHz, digital I/O, and D/A converters—and a choice of 3- or 8-slot chassis, you can configure the modular DAQ that best fits your application.
Keysight modular bit error ratio testers (BERTs) consist of the individual, interchangeable components which make up the high-performance BERT solutions for testing high-speed digital interfaces. These instruments include individual pattern generators, error detectors, analyzers, and clock data recovery modules to support evolving test needs. You can build your own BERT configuration based on data rate, modulation format, and functional needs, customizing a setup to meet your specific application requirements.

A digitizer is a device that converts analog signals into digital data for accurate measurement and analysis. It captures the input analog signal by sampling it at high rates and quantizing it into a digital format. This allows for precise waveform analysis, measurement of signal characteristics, and the ability to store and process the data for further analysis. Digitizers are commonly used in applications requiring high-precision waveform capture, such as in scientific research, engineering, and industrial testing.
While both digitizers and oscilloscopes capture and analyze signals, their primary functions and applications differ:
In short, a digitizer is ideal for high-precision waveform capture and offline analysis, while an oscilloscope is optimized for real-time monitoring and troubleshooting of electrical signals.
Data acquisition (DAQ) is the systematic measurement and recording of electrical characteristics or physical metrics with one of these end goals:
A dynamic DAQ can sample a single or multiple sensors’ dynamic signals at a high sampling rate using its built-in hardware signal digitizer. Hence, it can capture transient signals of voltage, current, vibration, or structural stress changes. A modern DAQ has a built-in fast Fourier transform (FFT) mathematic algorithm to transform a time-domain signal display into a frequency-domain signal display. An engineer can then analyze the dynamic signal in both the time and frequency domains.
