4.1 Front Panel Controls and Connectors

• Display Screen: High-resolution color display for waveform visualization and menu navigation.
• Function Buttons (F1-F6): Context-sensitive buttons for menu selections.
• Control Knobs: For adjusting vertical scale (Volts/Div), horizontal scale (Sec/Div), trigger level, and menu navigation.
• Channel Inputs (CH1-CH4): BNC connectors for connecting oscilloscope probes.
• Gen Out: Output for the arbitrary function waveform generator.
• Ext Trig: External trigger input.
• USB Host/Device Ports: For data storage (U-stick) and PC communication.

4.2 Side and Rear Panels

The side panels primarily feature ventilation slots to ensure adequate cooling during operation. The rear panel typically houses the power input and any optional communication ports (e.g., RS232, LAN).

5. Setup

5.1 Power Connection

1. Connect the provided power cord to the power input on the rear panel of the oscilloscope.
2. Plug the other end of the power cord into a grounded AC power outlet.
3. Press the power button, usually located on the front or side panel, to turn on the instrument.

5.2 Probe Connection and Compensation

1. Connect an oscilloscope probe to one of the BNC input channels (CH1-CH4).
2. Attach the probe tip to the probe compensation output (usually a square wave test point on the front panel).
3. Adjust the compensation trimmer on the probe until a flat-top square wave is displayed on the screen. This ensures accurate measurements.

5.3 Initial Settings

Upon first power-on or after a factory reset, the oscilloscope will typically default to standard settings. It is recommended to perform a self-calibration if available in the utility menu for optimal performance.

6. Operating Instructions

6.1 Basic Oscilloscope Operation

• Vertical Controls: Use the Volts/Div knobs for each channel to adjust the vertical scale of the waveform. Use the position knobs to shift the waveform vertically.
• Horizontal Controls: Use the Sec/Div knob to adjust the horizontal time base. The position knob shifts the waveform horizontally.
• Trigger System: The advanced digital trigger system offers high sensitivity. Use the Trigger Level knob to set the trigger point. Select trigger types (edge, overtime, pulse, pattern, interval, etc.) from the trigger menu.
• Auto Measurement: The device supports over 32 types of auto measurement functions. Access these through the measurement menu to automatically display parameters like Vpp, Vmax, Vmin, Frequency, Period, etc.
• Serial Bus Triggering and Decode: For analyzing serial communication protocols, use the dedicated functions to trigger on and decode bus data. Information can be displayed in a table format.

6.2 Arbitrary Function Waveform Generator (AFG)

The integrated AFG can generate various waveforms up to 25MHz with 12-bit resolution.

• Connect the signal output line from the "Gen Out" port to your circuit or another oscilloscope input.
• Access the AFG menu to select waveform types (ARB, square, sine, triangular, trapezoidal, impulse, DC), frequency, amplitude, and offset.
• The AFG is useful for simulating sensors and testing circuit responses.

6.3 Data Storage and Communication

• USB Host: Insert a U-stick into the USB Host port for saving waveforms, screenshots, or instrument settings.
• USB Device: Connect the oscilloscope to a PC using the USB Device port for remote control and data transfer via Hantek software.
• SCPI Commands: The instrument supports a variety of SCPI remote control commands for automated testing.
• Optional Ports: If equipped, RS232 and LAN ports provide additional communication options.
