5. Setup

5.1 Charging the Battery

The oscilloscope is powered by a built-in 4000mAh lithium battery. Before first use, ensure the device is fully charged. Connect the provided charging cable to the device's charging port and a suitable USB power adapter (not included). The charging indicator will show the charging status.

5.2 Attaching Probes

Connect the oscilloscope probes to the BNC connectors on the top of the device. Ensure a secure connection by twisting the probe connector until it locks into place. The device supports two channels.

5.3 Initial Power On

Press and hold the power button (location typically on the side or front panel) until the display illuminates. The device will perform a self-test and then display the main measurement interface.

6. Operating Instructions

6.1 Basic Measurement

1. Power On: Turn on the oscilloscope as described in Section 5.3.
2. Connect Probe: Attach a probe to the desired channel (CH1 or CH2).
3. Connect to Circuit: Connect the probe tip to the test point in your circuit and the ground clip to the circuit's ground.
4. Auto-Set: Press the "Auto" button to automatically adjust vertical and horizontal settings for a stable waveform display.
5. Adjust Settings: Use the navigation buttons and "Menu" button to fine-tune vertical sensitivity (V/div), time base (s/div), and trigger settings as needed.
6. Read Measurements: The display will show real-time waveform data and automatic measurements (e.g., Frequency, P-eak to P-eak).

6.2 Signal Generator Function

The oscilloscope can also function as a signal generator. The output port for the signal generator is typically located at the bottom of the device (red hole for signal, black hole for GND).

1. Access Generator: Navigate to the signal generator function through the menu.
2. Select Waveform: Choose the desired waveform type (sine, square, triangle, etc.).
3. Set Frequency: Adjust the output frequency. Sine waves support 0-10MHz, others 0-2MHz.
4. Connect Output: Connect the signal generator output to your target circuit.

6.3 FFT Spectrum Analysis

The FFT (Fast Fourier Transform) function allows for frequency domain analysis of signals.

1. Enter FFT Mode: Select FFT from the main menu.
2. Choose Display Mode: Select between logarithmic, linear, or music spectrum display modes based on your analysis needs.
3. Analyze Spectrum: Observe the frequency components of your input signal.

6.4 Waveform Saving and Viewing

To save a waveform displayed on the screen:

1. Save Waveform: Press the "Save" button (or navigate via menu) to capture the current waveform.
2. View Saved Waveforms: Access the waveform preview page to browse saved waveforms. Up to 250 waveforms can be stored.
3. Delete Waveforms: Unwanted waveforms can be deleted from the storage.
