The MXO 4 series is the first of a new generation of oscilloscopes that excels in both performance and value. The instruments deliver a once-in-a-decade engineering breakthrough for accelerated insight. A touch above other oscilloscopes in its segment, the MXO 4 series oscilloscope sports an impressive 13.3" Full HD capacitive touchscreen and an intuitive user interface with a learning curve of less than 15 minutes.

The MXO 4 series oscilloscopes utilize leading-edge technologies to achieve fast and accurate results. Custom technology and innovative features in its oscilloscopes quickly boost your understanding of circuit behaviors. 

All MXO 4 series oscilloscopes incorporate a 12-bit A/D converter. 12-bit vertical resolution delivers 4096 quantization levels for precise vertical sampling. This is a 16x improvement over 8-bit ADCs. The ADC stays in 12-bit mode all the time, even at the fastest sample rates. Offering a user tradeoff between bandwidth and bits of resolution, HD mode, implemented in hardware for fast speed, achieves up to 18-bit vertical resolution. This allows you to see sharper waveforms with more signal details that would otherwise be masked by noise.

After bandwidth and sample rate, memory depth is the most important attribute that determines the product’s ability to handle a large range of troubleshooting tasks. With 400 Mpoints acquisition memory standard on all four channels simultaneously, the MXO 4 series oscilloscope offers up to 100 times the standard memory compared to the primary competitor.

The MXO 4 series digital trigger is up to 10 000 times more sensitive than all competitors that are still using older analog trigger architectures. Triggering sensitivity enables users to isolate difficult-to-find small physical layer anomalies in the presence of large signals, accelerating debug and troubleshooting.

Use the up to 18 bit HD mode on the trigger to reduce measurement system noise. The digital trigger architecture makes it possible to adapt the cutoff frequency of the digital lowpass filter to the signal to be measured. Unlike oscilloscopes with analog trigger circuits, the same filter settings can be used for both the trigger signal and the measurement signal. As a result, noise on the trigger signal can be suppressed, for instance while simultaneously capturing and displaying the filtered or unfiltered measurement signal.

The MXO 4 series oscilloscope is engineered with spectrum analysis in mind to bring forward fast and powerful analysis capabilities. It boasts an industry leading spectrum acquisition rate of 45 000 FFT/s. This allows capture of spurious spectrum events, especially when doing EMI debugging. The pristine RF characteristics of the instrument balance great spectrum performance with the synchronized time domain view.

You can configure the spectrum analysis function of the R&S®MXO 4 by simply entering typical parameters: center frequency, span and resolution bandwidth (RBW). The spectrum settings are independent of the time domain settings, but the time and frequency domains are time-correlated.

The statistical confidence in results is higher the more waveforms are acquired. A high update rate increases the likelihood of detecting and displaying signal faults and including them in analysis. The high update rate enables the MXO 4 to generate trustworthy statistical results based on a high number of waveforms in a short time. This is crucial for quickly understanding electronic circuits.

The MXO 4 series oscilloscope offers an outstanding sensitivity down to 500 μV/div without any unexpected reduction in bandwidth. With offset of ±5 V at higher sensitivity vertical scale, you can easily place the signal at the center of the screen. Extended offset enables use of more sensitive vertical resolution, meaning higher ADC bits and lower noise.
