Community Comments about this Roadtest 
This oscilloscope plus options and accessories has a list price of about $20,000 (US). What makes this product standout out so much?? I'll let some element14 members explain:

• "The MXO4 manages to combine ridiculous hardware speed, a very quiet front-end, and a very well thought-out user interface in a general-purpose form factor."
• "It's an awesome scope indeed - some of those specs almost seem impossibly good to be true! I'm sure whoever gets to RoadTest this is going to be really happy about it."
• "I got to try one out at the R&S Scopetoberfest at [a] local office last month. It had all the options enabled (1.5GHz, AWG, etc). Quite an impressive instrument with an awesome HD display. I'd love to roadtest this instrument."

Description
The MXO44-245 is a 4 channel R&S® MXO 4 series oscilloscope with a 13.3-inch high-definition (1,920 x 1,080) display. Many applications, such as embedded systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters, require the observation of more than four analogue signals to verify and characterize device performance, and to debug challenging system issues.

Overall, the R&S®MXO 4 series is the first of a new generation of oscilloscopes that excels in both performance and value. The instruments deliver accelerated insight and have a real-time update rate of 4.5 million waveforms/s, meaning engineers can see more infrequent events than with any other instrument. With its 12-bit ADC, the R&S®MXO 4 series has 16 times the resolution of traditional 8-bit oscilloscopes at all sample rates without any compromises for more precise measurements. With a standard acquisition memory of 400 Mpoints on all four channels and an optional 800 Mpts interleaved, the instrument has up to 100 times the standard memory of comparable instruments. R&S®MXO 4 series oscilloscopes sport an impressive 13.3" Full HD capacitive touchscreen and an intuitive user interface with a learning curve of less than 15 minutes. All R&S®MXO 4 series oscilloscopes have the R&S®MXO4-B1 MSO hardware built into every instrument. The MSO option offers the logic probes required to start using the 16 digital channels.

At the heart of each R&S®MXO 4 series oscilloscope is a Rohde&Schwarz-developed application specific integrated circuit (ASIC): MXO-EP (extreme performance). MXO-EP processes 200 Gbit/s to deliver the world’s fastest update rate of up to 4.5 million acquisitions/s. See and capture more of your signal, faster. Find rare signal anomalies quickly. Experience the most responsive oscilloscope in the industry.

MXO-EP ASICs incorporate advanced digital triggering that evaluates the A/D converter samples in the acquisition path in real time. Trigger on small events of less than 1/10000 vertical division that no other oscilloscope can isolate. Choose your own trigger hysteresis. Apply digital filters to suppress noise to get the most precise triggering available.

Measurement accuracy is highly dependent on the components in the signal path, e.g. amplifiers, samplers and A/D converters. The workhorse of the R&S®MXO 4 series is an extremely low noise signal path including a 12 bit ADC. High definition mode (HD) increases vertical resolution to industry best 18 bit architecture.

R&S®MXO 4 series oscilloscopes come equipped with the industry’s deepest standard acquisition memory of 400 Mpoints per channel. Capture up to 80 ms of power up or power down sequences with the highest sample resolution of 200 ps. The memory controller in the MXO-EP ASIC ensures the oscilloscope stays responsive with deep memory.
