The DSO Nano V3 is a compact, pocket-sized digital storage oscilloscope designed for ease of use and portability, making it suitable for school labs, electric furniture repair, and general electric engineering tasks. Its design emphasizes simplicity and functionality, allowing users to perform essential waveform analysis on the go.
The primary function of the DSO Nano V3 is to visualize and analyze electrical signals. It captures and displays waveforms on its color TFT LCD, enabling users to observe the shape, amplitude, and timing of various signals. The device supports a range of triggering modes, including Auto, Normal, Single, None, and Scan, which are crucial for stabilizing repetitive signals and capturing transient events.
A key feature is its auto-measurement capability, which automatically calculates and displays important signal parameters such as frequency, cycle, duty cycle, peak-to-peak voltage (Vpp), root mean square voltage (Vrms), average voltage (Vavg), maximum voltage (Vmax), and minimum voltage (Vmin). This eliminates the need for manual calculations, speeding up analysis.
The DSO Nano V3 also incorporates precise measurement cursors, both vertical and horizontal, allowing users to manually pinpoint specific points on a waveform to measure time and voltage differences with accuracy. This is particularly useful for detailed analysis of signal characteristics that might not be covered by auto-measurements.
For signal generation, the device includes an inbuilt test signal generator, capable of producing signals within a specified frequency range. This can be used for testing circuits or calibrating the oscilloscope itself.
Waveform storage is another important function, enabling users to save captured waveforms to the device's internal memory. These stored waveforms can then be recalled for later analysis or comparison with live signals. The device also supports connection to a PC via USB, facilitating the transfer of waveform data and images for more in-depth analysis or archiving on a computer.
The DSO Nano V3 is designed for intuitive operation. Its user interface is navigated using a set of buttons, including "Adjust Up," "Adjust Down," "Confirm/Mode," "Menu Clockwise," "Menu Counter Clockwise," and "Quick Adjust Run/Stop." These controls allow users to easily adjust parameters, select menu options, and control waveform acquisition.
The device's screen is divided into distinct areas: the Parameter Area, which displays current settings and measurement values, and the Measurement Area, where the waveform is graphically presented. This clear layout helps users quickly grasp the device's status and the characteristics of the signal being measured.
Specific parameters can be adjusted by navigating through the Parameter Area using the directional buttons and confirming selections with the "OK" button. For instance, users can adjust the y-axis voltage per grid, x-axis voltage per grid, triggering method, and other settings to optimize the waveform display.
The measurement operation instruction provides a detailed guide on how to utilize the device's features. For example, to measure a simple signal, users connect the probe, set the channel mode to AUTO, adjust time and voltage calibrations for a clear display, and then select the desired measurement items (like frequency or Vpp) from the Measurement Area. The measured values are then displayed on the screen.
The cursor measurement feature is particularly helpful for precise analysis. Users can activate vertical and horizontal cursors and move them to specific points on the waveform (e.g., crests and valleys) to measure time intervals (like signal cycle) or voltage differences (like peak-to-peak voltage).
Saving waveform images is straightforward. Users can navigate to the "Save" function in the Measurement Area, choose to save the waveform as a BMP file, and then transfer it to a PC for further analysis or documentation. This is useful for archiving specific signal events or sharing data.
Acquiring single signals, especially non-periodic ones like impulses, is a key capability. The manual guides users to set the appropriate trigger level and trigger edge (e.g., rising edge) based on prior knowledge of the signal. The device will then wait for the signal to match the triggering condition and display it once captured. This is crucial for analyzing transient phenomena that might otherwise be difficult to observe.
Comparing waveform signals is another advanced usage feature. Users can save a standard signal waveform to the device's memory and then load it while measuring an unknown signal. This allows for a direct visual comparison of the two waveforms on the screen, aiding in fault diagnosis or performance evaluation.
The DSO Nano V3 includes features and guidelines to ensure its longevity and reliable operation.
Battery recharging is a simple process. When the battery indicator shows low power or the display dims, the device can be recharged via its USB interface. It can be operated while recharging, ensuring continuous workflow.
Firmware upgrades are supported to keep the device's software up-to-date with the latest features and bug fixes. The process involves downloading the latest firmware from the manufacturer's website, entering a specific DFU (Device Firmware Upgrade) mode by simultaneously pressing a button and powering on the device, and then copying the firmware file to the device's virtual USB disk. The device automatically updates once the file extension changes, and a reboot completes the process.
The manual also outlines general safety rules, emphasizing the importance of using the appropriate power cord, connecting and disconnecting probes properly, and observing terminal ratings to prevent damage or electric shock. It advises against operating the device in humid, flammable, or explosive environments and recommends keeping its surface clean and dry.
A general inspection procedure is provided for new devices, advising users to check for shipping damage and proper functionality. If any issues are found, users are instructed to contact the company or distributor for support.
Functional inspection steps are also detailed, including connecting the oscilloscope to standard signals (e.g., a 20KHz, 5Vpp square wave) to verify that measured values align with standard values, allowing for calibration if minor discrepancies are observed.
Calibration features are integrated into the device, allowing users to perform "Cal Zero" (calibration without voltage) and "CalRange" (calibration with voltage) to maintain measurement accuracy. A "Master Reset" option is also available to restore the device to its factory settings if needed. These maintenance features ensure that the DSO Nano V3 remains a reliable tool for signal analysis over time.
