RIGOL DL850 Oscilloscope/Recorder: Core Performance and Technical Features
Flexible Modular Input Architecture:
The mainframe provides up to 16 module slots, allowing flexible mixing of various input modules:
Isolated Voltage/Current Modules: Directly measure high-voltage and high-current signals, supporting power calculation.
Universal Voltage Modules: High-precision voltage measurement, compatible with various sensors (e.g., thermocouples, strain gauges) when paired with signal conditioners.
High-Speed Sampling Modules: Offer sampling rates up to 100 MS/s for capturing transient events.
A single system can synchronously measure diverse heterogeneous signals—from DC to high frequencies, microvolts to kilovolts, and temperature to vibration.
Powerful Data Logging and Waveform Capture Capability:
Deep Memory: Maximum storage depth up to 2 Gpts, supporting ultra-long-duration or high-resolution data logging.
Hybrid Recording Mode: Enables simultaneous low-speed continuous logging and high-speed triggered capture, monitoring trends while capturing sporadic anomalies.
Segmented Storage: Optimizes storage space by continuously recording multiple triggered events.
Intelligent Triggering and Analysis Functions:
Provides rich triggering conditions, including edge, pulse width, window, logical (AND/OR) triggers, and intelligent triggers based on mathematical operations or parameter measurement results.
Built-in real-time calculation functions allow mathematical operations on input signals (e.g., integration, differentiation, FFT), custom scaling, power calculation, and direct logging of results.
Equipped with a large 10.4-inch touchscreen display, supporting multiple display formats such as waveforms, trend graphs, and numerical tables.
Convenient Data Management and Connectivity:
Built-in high-capacity hard drive for direct saving of data and settings.
Offers multiple interfaces including USB, LAN, GPIB, and VGA, facilitating data export, remote control, and screen extension.
Typical Application Scenarios:
Power Quality Analysis and Energy Consumption Monitoring: Synchronously logging multi-channel voltage and current waveforms to calculate parameters like power, harmonics, and flicker.
Electromechanical Equipment Development and Fault Diagnosis: Simultaneously monitoring control signals, three-phase currents, speed, vibration, and temperature of motor drives.
Automotive Electronics Testing: Logging CAN/LIN bus data, sensor signals, actuator control waveforms, and power rail noise.
Long-Term Environmental and Process Monitoring: Continuous logging of slow-varying signals (e.g., temperature, humidity, pressure, strain) over days or even months.
Professional System-Level Service Support:
The performance and accuracy of the DL850 system depend on the individual precision of each input module, synchronization across modules, correctness of triggering and calculation functions, and overall system stability.
Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department offers professional system-level services:
Module-Level Accuracy Calibration: Precision calibration of each input module’s gain, offset, linearity, and isolation according to module type (voltage, current, thermocouple, etc.) using relevant national standard instruments.
Channel-to-Channel Synchronization Calibration: Measuring and calibrating time offsets (skew) between all module channels to ensure accurate time correlation of heterogeneous signals.
High-Speed Sampling Module Performance Verification: Verifying dynamic characteristics of high-speed modules, such as bandwidth, sampling rate, and rise time.
Calculation and Trigger Function Verification: Validating the accuracy of built-in mathematical formulas, parameter measurement functions, and proper execution of complex trigger logic.
System Integration and Configuration Optimization: Providing optimal module configuration recommendations and system setting adjustments based on user testing needs.
Fault Diagnosis and Module Repair: Systematically diagnosing issues like measurement errors, channel failure, trigger malfunction, storage anomalies, and display faults, along with module or mainframe repair services.
Conclusion:
The RIGOL DL850 Oscilloscope/Recorder, through its unique cross-domain design, seamlessly integrates the transient insight of an oscilloscope with the multi-channel, long-term monitoring capability of a data logger, offering engineers unprecedented freedom in mixed-signal testing. It is a powerful tool for understanding complex system behavior, diagnosing intermittent faults, and validating design performance.
Ensuring this robust tool consistently delivers precise, synchronized, and reliable data in complex field and laboratory environments requires professional services spanning multidisciplinary metrology and system integration. By partnering with a professional service provider like Shenzhen Bao'an District Shajing Fangfengrui Instrument Equipment Business Department, users can ensure their DL850 system receives expert-level technical support throughout its lifecycle—from module calibration and system integration to long-term maintenance—laying a solid data foundation for critical product development and system validation tasks.
