Rigol’s Real-Time Digital Oscilloscopes Support Up to 13 GHz Bandwidth

Rigol announced the launch of its newest line of real-time digital oscilloscopes (RTO). The eighth-generation DS80000 series delivers up to 13-GHz analog bandwidth, 40 Gigasamples per second (GSa/s) real-time sampling rate, and increased sampling memory.

The four models—DS80604, DS80804, DS81004, and DS81304—come with an analog bandwidth of 6 GHz, 8 GHz, 10 GHz, and 13 GHz, respectively. All have four analog channels and one ext channel. The new RTO line focuses on higher bandwidth, deeper memory, high-fidelity signal acquisition, and interface improvements. They support a wide range of protocols and high-speed analysis options.

Key Features and Details

The four scope models share specifications, with bandwidth being the model-specific key feature.

• Memory depth: 500 Mpts (standard), 2 or 4 Gpts (optional)
• Waveform capture rate: 250,000 wfms/s
• Vertical resolution adjustable from 8 to 16 bits
• Vertical sensitivity range: 1 mV/div ~ 1 V/div at 50 Ω
• Timebase range: 20 ps/div ~ 1 ks/div

All scopes support USB/LAN/HDMI interfaces and cover a number of common protocols for compliance and analysis, including USB 2.0 and LAN for optional protocol compliance analysis. For optional series protocol analysis, the devices also support RS232/UART, I2C, SPI, CAN, CAN-FD, LIN, FlexRay, I2S, MIL-STD-1553, and USB 2.0.

The devices feature advanced jitter and eye diagram analysis and hardware-assisted FT. Trigger modes include edge, pulse, slope, video, pattern, duration, timeout, runt, window, delay, setup/hold, and Nth edge. All standard and optional triggers are on RS232, I2C, SPI, CAN, FlexRay, LIN, I2S, and MIL-STD-1553.

The scopes include a tiltable 15.6-inch HD capacitive touch screen display with gesture-enabled operation and multi-pane windowing, as well as an extended external display capability.

Higher Speed Applications in New Protocols

At 13 GHz, an oscilloscope can be used for high-speed serial buses such as USB 3.0, mobile industry processor interface (MIPI), Wi-Fi 7, and other high-speed RF and high-performance CPU-clock-level digital signals. Typical applications include high-speed signal protocol analysis and high-speed component and system performance validation. The advanced jitter and eye-diagram analysis functions improve embedded debugging, PLL performance validation, and high-speed serial bus checking. Protocol compliance validation, such as PCIe and USB 2.0, is also in the toolbox.

The new models are built on Rigol’s UltraVision III high-storage depth platform. UltraVision III technology comes with 2 Giga points (Gpts) memory depth standard and 4 Gpts optional. The additional memory depth enables longer samples, which, along with the high sampling rate, can deliver higher fidelity signal images than were possible with earlier models. The improved signal picture supports more complex analysis and complete and accurate data reconstruction. UltraVision III also brings hardware-accelerated fast Fourier transform (FFT) functionality.

DS80000 Hardware Interface

The DS80000 is a modular system built on Rigol’s StationMax II modular hardware platform. StationMax II integrates 13-GHz front-end modules with sampling modules and advanced algorithms. The system is expandable and upgradable.

The new scopes connect to signals via Rigol’s Smart Probe 2.0 Intelligent Probe System. SmartProbe 2.0 is a new 3.5-mm connector-based interface compatible with both new and prior generation active differential and passive probes. Adapters for older probes are compatible across test suites. The standard connector has a 50-Ω impedance level. The interface has an optional adaptor for 1-MΩ impedance applications.

The units can be used on the desktop or rack mounted. The DS80000 display screen is tiltable to aid in viewing and increase mounting flexibility. 

Keeping Up With Clock Speeds

Test and measurement toolmakers are ever trying to keep up with increasing clock speeds. Rigol’s latest entrant into the fray, the DS80000 series, brings ultra-high-speed capability, high analysis accuracy, and enhanced usability to the bench.
