1. Introduction
The Rigol MSO5074 is a high-performance four-channel digital/mixed signal oscilloscope designed for precise signal analysis and measurement. It features a 70 MHz bandwidth, an impressive real-time sample rate of up to 8 GSa/s, and a deep memory depth of 100 Mpts, expandable to 200 Mpts. This instrument is equipped with 16 digital channels (requiring an optional PLA2216 logic probe) and boasts a high waveform capture rate exceeding 500,000 waveforms per second, making it suitable for capturing transient events and analyzing complex signals.

2. Initial Setup
2.1 Unpacking and Inspection
Upon receiving your MSO5074 oscilloscope, carefully unpack all components and inspect them for any signs of damage during transit. Retain the original packaging for future transport or storage.
- Verify that all accessories listed in the packing list are present.
- Inspect the instrument for any physical damage, such as dents, scratches, or broken connectors.
- If any damage or missing items are found, contact your supplier immediately.
2.2 Power Connection
Connect the provided AC power cord to the power input on the rear panel of the oscilloscope. Ensure the power source matches the voltage requirements specified on the instrument's label. The MSO5074 operates on AC power.

2.3 Probe Connection
Connect the oscilloscope probes to the BNC input connectors on the front panel. Each channel (CH1, CH2, CH3, CH4) has a dedicated BNC input. For mixed-signal analysis, the 16 digital channels require the optional PLA2216 logic probe to be connected to the dedicated digital input port.

3. Operating Instructions
3.1 Powering On/Off
To power on the oscilloscope, press the power button located on the front panel. To power off, press and hold the power button until the unit shuts down.
3.2 User Interface Overview
The MSO5074 features a large touchscreen display for intuitive control, complemented by traditional physical knobs and buttons for precise adjustments. The interface allows for quick navigation through menus and settings.
3.3 Core Functions
- Sample Rate: Up to 8 GSa/s real-time sample rate ensures high-fidelity signal capture.
- Memory Depth: 100 Mpts standard, with an option to expand to 200 Mpts, allowing for longer capture times at high sample rates.
- Waveform Capture Rate: Over 500,000 waveforms per second, increasing the probability of capturing infrequent events.
- Digital Channels: 16 integrated digital channels for mixed-signal analysis (requires optional PLA2216 logic probe).
3.4 Signal Acquisition and Analysis
To acquire a signal, connect your probe to the desired test point and the corresponding channel input on the oscilloscope. Adjust the vertical scale (Volts/Div) and horizontal scale (Sec/Div) to properly display the waveform. Use the trigger settings to stabilize the waveform on the screen. The oscilloscope offers various measurement and analysis functions, including automatic measurements, FFT analysis, and protocol decoding.

4. Maintenance and Care
4.1 Cleaning
To maintain the performance and appearance of your oscilloscope, regularly clean its exterior. Use a soft, damp cloth with a mild detergent. Avoid abrasive cleaners or solvents that could damage the plastic components or screen. Ensure the instrument is powered off and disconnected from the power source before cleaning.
4.2 Storage
When not in use for extended periods, store the oscilloscope in a dry, dust-free environment, ideally in its original packaging or a protective case. Avoid extreme temperatures and humidity, which can affect the instrument's electronic components.
4.3 Firmware Updates
Rigol periodically releases firmware updates to enhance performance, add new features, and address any known issues. It is recommended to check the official Rigol website for the latest firmware versions and follow the provided instructions for updating your device.
5. Troubleshooting Common Issues
This section provides solutions to common issues you might encounter with your MSO5074 oscilloscope. For problems not listed here, please refer to the comprehensive user manual available on the Rigol website or contact technical support.
| Problem | Possible Cause / Solution |
|---|---|
| Oscilloscope does not power on. | Ensure the power cord is securely connected to both the oscilloscope and a working power outlet. Check the power switch position. |
| No waveform displayed. | Verify probes are correctly connected to the input channels and the signal source. Check channel enable settings. Adjust vertical (Volts/Div) and horizontal (Sec/Div) scales. Ensure trigger settings are appropriate for the signal. |
| Waveform is unstable or noisy. | Adjust trigger level and mode. Check probe compensation. Ensure proper grounding. Reduce environmental noise sources. |
| Touchscreen is unresponsive. | Restart the oscilloscope. Ensure the screen is clean and free of debris. If the issue persists, contact support. |
