Owon SDS200 Series Digital Oscilloscope User Manual

1. Introduction

The Owon SDS200 Series comprises portable 2-channel handheld digital oscilloscopes, designed for a wide range of applications including field debugging, electronics maintenance, and laboratory testing. These instruments offer reliable signal analysis in a compact and user-friendly form factor.

All models in the series feature a 7-inch TFT LCD display, a 1GS/s real-time sampling rate, 20M storage depth, and a built-in frequency meter. The 'S' models (SDS210S, SDS215S, SDS220S) further enhance functionality by including a built-in 25MHz 14-bit arbitrary waveform signal generator.

2. Model Variations

The SDS200 series offers several models with varying bandwidths and additional features:

• SDS210/215/220 (Base Series): These are the core models with bandwidths of 100MHz, 150MHz, and 200MHz respectively. They are ideal for routine signal observation and analysis tasks and do not include a built-in signal source.
• SDS210S/215S/220S (Enhanced "S" Series): These models match the bandwidths of the base series (100MHz, 150MHz, 200MHz) but include a built-in 25MHz arbitrary waveform signal generator. They are suited for users who require both signal analysis and test signal generation capabilities.

3. Setup and Package Contents

3.1 Package Contents

Before setting up your oscilloscope, please verify that all components are present in the package:

• Owon SDS200 Series Digital Oscilloscope (Main Instrument)
• USB Cable
• Oscilloscope Probes (x2)
• Power Cord
• Quick Guide
• BNC Cable (Exclusively included with "S" models: SDS210S, SDS215S, SDS220S)

3.2 Initial Power-On

1. Connect the power cord to the oscilloscope's power input and then to a suitable AC power outlet.
2. Press the power button located on the front panel to turn on the device.
3. The oscilloscope will perform a self-test and display the main waveform interface.
4. Connect the oscilloscope probes to the CH1 and CH2 input BNC connectors as needed for your measurements.
5. If using an 'S' model, connect the BNC cable to the signal generator output (AFG Output) if you intend to use the built-in signal generator.

4. Operating Instructions

4.1 Basic Controls and Display

The SDS200 series features a 7-inch high-definition TFT LCD display (800*480 pixels) for clear viewing of all signals and screen information. It supports simultaneous screen display and magnification for detailed signal observation.

4.2 Key Features and Functions

• Dual-channel Oscilloscope: All models offer two independent channels for simultaneous signal analysis.
• High Sampling Rate & Storage Depth: A real-time sampling rate of 1GS/s and a storage depth of 20Mpts ensure detailed capture and analysis of complex waveforms.
• Automatic Measurements: Supports 30 types of automatic measurements, including Period, Frequency, Mean, PK-PK, RMS, Max, Min, Top, Base, Amplitude, Overshoot, Preshoot, Rise Time, Fall Time, PulseWidth, +PulseWidth, +Duty Cycle, -Duty Cycle, Delay A→B↑, Delay A→B↓, Cycle RMS, Cursor RMS, Screen Duty, Phase, +PulseCount, -PulseCount, RiseEdgeCnt, FallEdgeCnt, Area, and Cycle Area. This allows for "one-click" measurement of various waveform parameters.
• FFT Spectrum Analysis: The Fast Fourier Transform (FFT) mathematical operation converts time-domain signals into frequency-domain components, useful for measuring harmonic components, distortion, noise characteristics, and vibration analysis.
• 6-bit High-Precision Hardware Frequency Counter: Built into the oscilloscope, this feature measures the frequency of the input signal (CH1 or CH2 selectable as source) with a 6-digit numerical display.
• Storage/Invocation: Save and recall various data formats such as waveforms, reference waveforms, CSV files, and images for comparative analysis.
• X-Y Mode: Provides a three-screen display for convenient phase difference measurement and component characteristic testing.

4.3 Arbitrary Waveform Signal Generator (S Models Only)

For SDS210S, SDS215S, and SDS220S models, a built-in arbitrary waveform signal generator is available. This function supports:

• Maximum output frequency: 25MHz
• Real-time sampling rate: 125MSa/s
• Arbitrary wave length: 8K
• Output amplitude: 5Vpp ~ -3Vpp (50Ω)
• Standard waveforms: Sine, square, wave, ramp wave, pulse wave, arbitrary wave
• Arbitrary waveforms: Sine, exponential rise, exponential decline, Gaussian (more than 160 kinds)

4.4 Remote Control and PC Software

The oscilloscope supports remote control and secondary development through its USB Device interface. It is compatible with SCPI and LabVIEW functions. Free computer software and programming development demos are provided to facilitate remote control of the instrument and custom application development.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the oscilloscope. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device.
• Storage: Store the oscilloscope in a dry, dust-free environment away from direct sunlight and extreme temperatures.
• Probe Care: Handle probes carefully. Avoid bending or stressing the cables excessively. Clean probe tips with isopropyl alcohol if necessary.
• Software Updates: Periodically check the manufacturer's website for firmware updates to ensure optimal performance and access to new features.

6. Troubleshooting

This section provides basic troubleshooting steps for common issues. For more complex problems, please refer to the full user manual (if available) or contact technical support.

• No Power:
  • Ensure the power cord is securely connected to both the oscilloscope and the power outlet.
  • Verify the power outlet is functional.
  • Check the power button is fully pressed.
• No Signal Displayed:
  • Ensure probes are correctly connected to the input channels and the circuit under test.
  • Check probe attenuation settings on both the probe and the oscilloscope match.
  • Adjust vertical (Volts/Div) and horizontal (Time/Div) scales.
  • Verify trigger settings (e.g., trigger level, mode) are appropriate for the signal.
• Unstable Waveform:
  • Adjust the trigger level to a stable point on the waveform.
  • Change the trigger mode (e.g., from Auto to Normal or Single).
  • Check for noise in the signal path.

7. Specifications

Below are the general specifications for the Owon SDS200 Series Digital Oscilloscopes. Specific parameters may vary slightly between models (SDS210, SDS215, SDS220, SDS210S, SDS215S, SDS220S).

8. User Tips

• Probe Compensation: Always perform probe compensation before making critical measurements to ensure accuracy.
• Grounding: Ensure proper grounding of both the oscilloscope and the circuit under test to prevent measurement errors and ensure safety.
• Triggering: Master the various triggering options (Edge, Video, Pulse, Slope, etc.) to capture stable waveforms, especially for complex or intermittent signals.
• Automatic Measurements: Utilize the 30 automatic measurement functions for quick and precise parameter readings, saving time compared to manual cursor measurements.
• Data Storage: Regularly save important waveforms and settings to the internal memory or a USB drive for later analysis or comparison.
