6. Logic Analyzer Connection (Optional): If using the logic analyzer, connect the logic analyzer cables to the 'LOGIC IN' and 'LOGIC OUT' ports and to your target circuit.
7. Network Connection (Optional): For network control or PoE functionality, connect an Ethernet cable to the LAN/PoE port.

5.1. Multi-Device Connection Example

This diagram illustrates a network setup where multiple Hantek oscilloscopes can be connected to a single computer. The oscilloscopes are connected to a PoE switch, which provides both data and power. The PoE switch then connects to the computer, allowing for centralized control and data acquisition from multiple devices. Fiber-optic communication is also shown as an option for extended distances.

6. Operating Instructions

Once the software is installed and the device is connected, launch the Hantek application on your computer. The software interface is designed to be similar to a traditional benchtop oscilloscope, providing intuitive control over the device's functions.

6.1. Oscilloscope Functions

• Channel Selection: Enable or disable the 4 analog channels (CH1-CH4) as needed.
• Vertical Controls: Adjust voltage per division (V/DIV) and coupling (AC/DC/GND) for each channel. The device offers 1mV-10V/DIV sensitivity.
• Horizontal Controls: Adjust time base (s/DIV) to control the sweep speed.
• Triggering: Configure trigger source (CH1-CH4, EXT), mode (Edge, Pulse, Video, Slope, Timeout), and level to stabilize waveforms.
• Measurements: Utilize over 20 automatic measurement functions (Vpp, Vmax, Vmin, Vavg, RMS, Frequency, Period, Rise Time, Fall Time, etc.) and dynamic cursor tracking.
• Waveform Display: Options include waveform averaging, afterglow, lightness control, reverse, and mathematical operations (add, subtract, multiply, divide, X-Y display).
• FFT Spectrum Analyzer: Perform frequency domain analysis using the built-in FFT function.
• PASS/FAIL Test: Set up criteria for automated waveform comparison against defined masks.
• Recording: Continuous waveform recording and replay function with 200Hz recording bandwidth.

6.2. Logic Analyzer Functions

The integrated 16-channel logic analyzer allows for digital signal analysis. Connect your digital signals to the 'LOGIC IN' port and configure the software for threshold levels and trigger conditions to capture and analyze digital waveforms.
