What is the MXO44-PRO?

The Rohde & Schwarz MXO44-PRO is a package with an MXO4 oscilloscope (4 channel / 500 MHz) and the following options:

• MXO4-B6 - Arbitrary waveform generator
• MXO4-K31 - Power analysis
• MXO4-K36 - Frequency response analysis
• MXO4-K510 - Low speed serial buses (I2C/SPI/QuadSPI/UART/RS-232/RS-422/RS-485)
• MXO4-K520 - Automotive protocols (CAN/CAN FD/CAN XL/LIN)
• MXO4-K530 - Aerospace protocols (ARINC429, MIL-STD-1553)
• MXO4-K550 - MIPI low speed protocols
• MXO4-K560 - Automotive Ethernet bus (10BASE-T1S)

Equipped with the MXO4-B6 option, the MXO 4 series oscilloscope offers a fully integrated two-channel 100 MHz arbitrary waveform generator. With 625 Msample/s and 16 bit resolution, the generator is suitable for implementing prototype hardware and for educational purposes. The integrated generator provides both standard and arbitrary stimulus to the DUT. The generator can be operated as a function or modulation generator. It also supports sweep mode.

The integrated arbitrary waveform generator provides stimulus output of sine, square, pulse, ramp, triangle, sinc, arbitrary and noise waveforms to your device under test. For all waveforms, you can set the frequency, amplitude, offset and noise and also add a burst.

The modulation feature supports AM, FM, FSK and PWM modulations with modulation shapes of sine, rectangle, triangle and ramp.

Measuring AC circuit power quality can be tedious due to the numerous calculations required to determine the real, apparent and reactive power. An oscilloscope is ideal for this work because it provides a clear view of the waveform characteristics between voltage and current, allowing engineers to quickly identify and resolve problems. The MXO4-K31 enables power quality measurements and provides concurrent analysis of three pairs of voltage and current sources.

Different standards for limiting the harmonic current must be met in AC power supplies. Identifying distortion from harmonic content is tedious without a proper tool. The R&S MXO4-K31 includes current harmonic analysis to help test in line with all common standards. Users can setup three concurrent harmonic measurements.

• Power quality: active, apparent and reactive power, crest factor and phase angle
• Current harmonics: THD RMS and fundamental functions, in line with EN6100-3-2 classes A, B, C, D, MIL-STD-1399 and RTCA DO-160

The MXO4-K36 frequency response analysis (FRA) option lets you perform low frequency response analysis on your oscilloscope easily and quickly. It measures the frequency response of a variety of electronic devices, including passive filters and amplifier circuits.

For switched-mode power supplies, it measures the control loop response (CLR) and power supply rejection ratio (PSRR).

The FRA option uses the oscilloscope’s built-in arbitrary waveform generator to create stimulus signals in the range from 10 mHz to 100 MHz. Measuring the voltage ratios of the stimulus signal and the output signal of the DUT at each test frequency, the oscilloscope plots gain and phase logarithmically.

The MXO4-K36 allows users to configure amplitude profiles for the generator output level. This helps optimize signal-to-noise ratio (SNR) at different frequencies when measuring CLR and PSRR. Users can also load lookup tables for generator settings.

This package includes the following:

• MXO4-K510 - Low speed serial buses (I2C/SPI/QuadSPI/UART/RS-232/RS-422/RS-485)
• MXO4-K520 - Automotive protocols (CAN/CAN FD/CAN XL/LIN)
• MXO4-K530 - Aerospace protocols (ARINC429, MIL-STD-1553)
• MXO4-K550 - MIPI low speed protocols
• MXO4-K560 - Automotive Ethernet bus (10BASE-T1S)

With the MXO 4 series, you can experience protocol analysis innovation. Traditional oscilloscopes typically capture data packets in the decoding path using the same sample rate as in the waveform path.

The MXO 4 series offers dual-path protocol analysis. You can set the instrument sample rate for the waveform path, and the oscilloscope will automatically use another internal decoupled sample rate for the decoding path. Even with very slow sample rates, the protocol data is correctly decoded. With conventional oscilloscopes, decoding would not be possible due to undersampling.

Zoom in and out on the decoded protocol data using the vertical and horizontal control knobs or using your fingers on the touchscreen. Use the R&S SmartGrid function to rearrange the windows displayed on the screen to best fit your viewing preferences. The decoded bus data can be overlaid on the captured signal and/or displayed in a separate window.

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.

The MXO 4 series flexibly adapts to relevant project updates. You can simply install the necessary software licenses, e.g., triggering and decoding of serial protocols or the frequency response analysis option. The waveform generator and MSO capabilities are built-in and just need to be activated. The bandwidth can be upgraded up to 1.5 GHz via keycode. All this makes retrofitting very easy.
