A completely new series to its oscilloscope portfolio that delivers a number of industry firsts. The new R&S MXO 4 series oscilloscopes feature a fast real-time update rate of over 4.5 million acquisitions per second.

The new R&S MXO 4 series is the first in the next generation of oscilloscopes by Rohde & Schwarz. The R&S MXO 4 oscilloscopes come in four-channel models with bandwidths of 200 MHz, 350 MHz, 500 MHz, 1 GHz, and 1.5 GHz. It offers some unparalleled functions and excel in both performance and value. The oscilloskops offers an instant view of signal details with an update rate of 4.5 M acquisitions per second, revealing more signal activity than any other available oscilloscope. Development teams can quickly see and isolate infrequent events, get a better understanding of physical layer signals and test faster. This is unparalleled in the industry.

A unique 200 Gbps processing ASIC makes this feature possible. It is one of several new technology blocks Rohde & Schwarz engineers developed and implemented for the first time in the R&S MXO 4 series. Dr. Andreas Werner, Vice President Oscilloscopes at Rohde & Schwarz, explains: “The new hardware and software technology blocks and architecture allowed our development team to achieve a once-in-a-decade engineering breakthrough. Our customers will experience a whole new level of performance, and all at a price more affordable than has ever been seen on the market.”

The R&S MXO 4 series incorporates a 12-bit ADC that operates across all the instrument sample rates with an 18-bit vertical resolution architecture for greater resolution precision than any other oscilloscope. It also has a low noise and a large offset range (± 5V with a 500 µV/div scaling) in its class. Users can see DC and other signals with more precision than with any other oscilloscope on the market.

With a deep standard memory and digital trigger for more details

In addition to bandwidth and sample rate, memory depth is an important factor and determines whether an oscilloscope can handle a large range of troubleshooting tasks. More acquisition memory enables oscilloscopes to cap­ture more time and retain rated bandwidth information for shorter time base settings. With a simultaneous standard acquisition memory of 400 Mpts on all four channels, the R&S MXO 4 series has up to 100 times the standard memory of its primary competition. The additional memory also provides extra measurement capability when needed.

Once only available in higher performance oscillo­scopes with higher price points, the digital trigger comes standard with all R&S MXO 4 series oscilloscopes. The trigger sensitivity of 1/10,000 division can isolate difficult-to-find small physical layer anomalies in the presence of large signals. No competitive oscilloscope has this degree of trigger sensitivity for isolating small signals. The digital trigger complements the 18-bit vertical architecture, allowing users to fully utilize the precision. Many development engineers need to debug products and test in both the time and frequency domains. In addition to time domain measurements, R&S MXO 4 series oscilloscopes have superior RF spectrum measurement capabilities. They are the first oscilloscopes to perform 45,000 FFTs (Fast Fourier Transforms) per second, while comparable oscilloscopes deliver fewer than 10 FFTs per second. This base feature lets engineers view more RF signals than with any other oscilloscope in its class.

Using an oscilloscope is a visual experience, where a lot of time is spent viewing a display. The R&S MXO 4 series incorporates a 13.3” full-HD capacitive touchscreen and an intuitive user interface. The instrument’s small footprint, audible noise of less than a whisper, VESA mounting and a rackmount kit for installation in integrated environments make R&S MXO 4 oscilloscopes ideal for any engineering workspace. (heh)
