In its new Infiniium MXR-Series mixed-signal oscilloscope, Keysight Technologies offers what is said to be the first oscilloscope with 8 analog channels at 6 GHz and 16 simultaneous digital channels. Thanks to advanced ASIC-driven processing, the MXR-Series scopes embody a highly versatile instrument, encompassing the functionalities of a real-time spectrum analyzer, oscilloscope, digital voltmeter, waveform generator, Bode plotter, counter, protocol analyzer, and logic analyzer. The result is less testbench complexity and a smoother workflow.

Many applications, such as high-speed digital designs, power-integrity verification, Wi-Fi 6, IoT, IIoT, and gallium-nitride (GaN) semiconductors operate at frequencies between 2 GHz and 6 GHz. Testing these new products requires time- and frequency-domain equipment capable of simultaneous analog and digital channels, ideally with software-enabled protocols, standards, built-in test assistance, and test team remote collaboration. The MXR-Series scope addresses these test applications armed with an extensive suite of software solutions focused on power integrity, high-speed digital test, and verification. Built-in software includes a fault hunter function that speeds root cause identification and resolution of rare or randomly occurring errors.

The Keysight Infiniium MXR series oscilloscope brings several key benefits:

Incorporating a real-time spectrum analyzer achieves a 100% probability of detection in the frequency domain, even for asynchronous errors.
A built-in fault hunter function learns normal signals and compares them over time to find abnormal signals, capturing everything else that occurs when the abnormal signals happen. The result: rapid problem resolution for troubleshooting irregular, random, or spurious signals.
Simultaneous 8 analog channels and 16 digital channels enable monitoring and analysis of complex signal interactions. Coupled with 3X higher bandwidth than any other 8-channel oscilloscopes, it allows test engineers to open a wider and more insightful window into designs.
Powerful remote collaboration with PathWave Infiniium Offline Analysis software enables design teams to do extensive analysis and data manipulation after bench measurements are complete, enhancing the efficiency and effectiveness of the test bench.
