The Rohde & Schwarz RTB 2 is the successor to the Rohde & Schwarz RTB2000, which has enjoyed significant success in the market. Building on this success, Rohde & Schwarz has decided to release an updated version to ensure we continue to serve this important market segment in the coming years.
The Rohde & Schwarz RTB 2 oscilloscope offers key specifications that makes it a versatile tool for engineers and educators. It features bandwidth options ranging from 70 MHz to 300 MHz, with a 10-bit ADC providing highresolution signal capture. The device supports sampling rates of up to 2.5 Gsample/s and includes 10 Mpoints memory (up to 20 Mpoints in interleaved mode). The oscilloscope is available in 2- and 4-channel models, both MSO-ready, allowing for the addition of 16 digital channels. Standard features include a 25 MHz arbitrary waveform generator, segmented memory for capturing up to 13,000 segments, and a large 10.1" capacitive touchscreen for intuitive operation.
Rohde & Schwarz RTB 2 series oscilloscopes combine the power of ten with smart operating concepts to make them a perfect general-purpose tool for students, hobbyists, technicians and engineers. The Rohde & Schwarz RTB 2 series is the follow up to the high-performance RTB2000 oscilloscope. Try one in the lab and see the difference.
The new Rohde & Schwarz RTB 2 oscilloscope is MSO-ready, meaning no additional license is needed to utilize the 16 digital channels. This enables seamless integration of both digital and analog signals, making it ideal for mixed-signal analysis. All the user needs is the RTB2-B1 accessory, which consist of the MSO-logic probes.
Additionally, the oscilloscope includes an arbitrary waveform generator as standard, capable of generating signals with an output frequency of up to 25 MHz and pattern speeds up to 50 Mbit/s. This generator can act as a stimulus for circuits or emulate missing components, making it especially useful in educational settings. Users can import waveforms and patterns from CSV files or directly from oscilloscope captures, with the option to add noise for simulating challenging environments. Predefined patterns for I2C, SPI, UART, and CAN/LIN protocols are available, and users can either select counters or manually input patterns.
The Rohde & Schwarz RTB 2 segmented memory feature allows for capturing intermittent signals, such as laser pulses, serial bus activity, or RF pulses, with storage for up to 13,000 segments and a total of 260 Mpoints. Its history mode lets users review past acquisitions even after stopping the device, with full access to tools like serial bus decoding and automatic measurements. The persistence function overlays all captured waveforms, while measurement statistics track signal changes over time.
Software Package
The RTB2-PK1 is a software option bundle for the Rohde & Schwarz RTB 2 oscilloscope, designed to enhance its functionality with additional features. This bundle includes the following options:
1. I2C/SPI serial triggering and decoding
This option enables the oscilloscope to trigger and decode communication protocols like I2C and SPI, which are commonly used in embedded systems. It allows engineers to troubleshoot communication issues efficiently by visually decoding the signals, saving time compared to manual analysis.
2. UART/RS-232/RS-422/RS-485 serial triggering and decoding
This feature provides support for UART, RS-232, RS-422, and RS-485 protocols, offering comprehensive triggering and decoding capabilities for these widely used serial communication standards. This is especially useful in debugging serial connections in embedded and industrial systems.
3. CAN/LIN serial triggering and decoding
This option focuses on CAN and LIN bus systems, which are essential in automotive and industrial environments. With this tool, users can decode and trigger these protocols to easily identify communication errors and ensure system reliability.
4. Frequency Response Analysis (Bode plot)
This feature turns the oscilloscope into a powerful tool for frequency response analysis. It allows users to plot Bode diagrams, which are crucial for analyzing the stability and behavior of electronic systems like filters, amplifiers, and power supplies. This option helps engineers optimize circuit performance by providing detailed gain and phase information across a range of frequencies.
Enhanced protocol analysis: With support for various serial communication protocols, engineers can quickly detect and resolve issues in their designs
Timesaving: Automated triggering and decoding reduce the time spent manually analyzing signal behavior
Versatility: The frequency response analysis tool broadens the oscilloscope's application beyond time-domain measurements, making it useful for circuit analysis and power electronics
Convenience: All options are integrated into the oscilloscope interface, providing an intuitive and seamless user experience
The Rohde & Schwarz RTB 2 oscilloscope launches with an updated firmware that brings several key enhancements and new features alongside various bug fixes. These improvements are designed to increase usability, functionality, and measurement capabilities for users This firmware will also work on the Rohde & Schwarz RTB2000, which shows that R&S is highly interested in long-term customer engagement and a high life-time value of the products. Here are the main changes and their benefits:
1. Increase Number of parallel Measurements from 6 to 8
With the firmware update, the number of simultaneous measurement slots will increase from 6 to 8, allowing users to display and track more measurement parameters in real-time. This improvement means more data is available at a glance, which is particularly useful in complex testing scenarios where multiple variables need to be monitored. It enhances the oscilloscope's capability for comprehensive analysis, enabling users to gather more information without needing to switch between different measurements.
2. Gate Measurement Capability
The addition of gate measurement functionality allows users to limit measurements to specific portions of a waveform. This feature is particularly beneficial for focusing on specific time intervals or sections of a signal, improving the precision of measurements by ignoring irrelevant portions of the waveform. It is ideal for analyzing repeating signals, bursts, or events within a signal, providing more targeted analysis and enabling users to better isolate and troubleshoot issues within a specific time frame.
3. New Trigger Types: Runt and Rise Time
Two new trigger types have been added: runt and rise time.
Runt trigger detects signals that fail to reach a full logic high or low, which is crucial for identifying signal integrity issues like glitches or incomplete transitions in digital circuits. This feature helps engineers pinpoint intermittent problems that could cause system failures.
Rise time trigger enables users to detect signals based on how quickly the waveform rises from one level to another, which is critical for analyzing the speed of transitions in high-frequency circuits. This trigger type is particularly useful in applications requiring precise timing and performance optimization in high-speed digital systems.
