Features and benefits

Why I love FNIRSI 1C15

  • The 110MHz Analog Bandwidth allows the FNIRSI 1C15 to capture a wide range of signals, from low-frequency control signals to high-frequency communication protocols, providing clear and detailed visualization of complex waveforms that are crucial for advanced diagnostics and development. This ensures that even fast-changing electrical events are accurately represented, preventing aliasing and loss of critical information.
  • The 500MS/s Real-Time Sampling Rate enables the oscilloscope to digitize signals at an incredibly high speed, allowing it to accurately reconstruct waveforms without missing transient events or subtle details. This high sampling rate is particularly beneficial when dealing with high-frequency signals or single-shot events, ensuring that the captured data is a true representation of the original signal.
  • The 12kpts Storage Depth provides ample memory to store a significant portion of the captured waveform, allowing users to zoom in and analyze fine details without losing context. This extended record length is invaluable for observing slow-changing signals over time or capturing multiple events within a single acquisition, facilitating in-depth post-capture analysis.
  • Equipped with a 3000mAh Rechargeable Battery, the FNIRSI 1C15 offers over 10 hours of continuous operation on a full charge. This extended battery life makes it an ideal tool for field work, remote diagnostics, or any scenario where access to a power outlet is limited, providing unparalleled portability and reliability for prolonged testing sessions.
  • The One-Key Quick Auto Function simplifies setup and operation, automatically adjusting vertical, horizontal, and trigger settings to display a stable waveform with a single press. This feature significantly reduces the learning curve for new users and speeds up troubleshooting for experienced engineers, making waveform acquisition as intuitive as using a desktop oscilloscope.
  • The Joystick Control replaces traditional arrow keys, offering a more ergonomic and efficient way to navigate menus and adjust parameters. This intuitive interface enhances user experience, allowing for quicker adjustments and smoother interaction with the device, which is crucial for precise waveform manipulation and analysis.
    The inclusion of a 1kHz Self-Checking Square Wave provides a convenient and reliable method for calibrating the oscilloscope and verifying probe compensation. This built-in diagnostic tool ensures that the device is always performing optimally, giving users confidence in their measurements and maintaining accuracy across various applications.
  • The 14 Types of Waveform Measurements offer a comprehensive suite of analytical tools, allowing users to quickly extract key parameters such as frequency, period, peak-to-peak voltage, RMS, and more. This extensive measurement capability streamlines the analysis process, providing immediate insights into signal characteristics without manual calculations.
  • With a Max Waveform Capture Rate of 30,000wfm/s, the oscilloscope can rapidly update the display with new waveforms, making it easier to spot intermittent glitches or rare events that might be missed by devices with slower capture rates. This high capture rate is essential for debugging complex digital circuits and identifying elusive signal anomalies.
  • The Voltage Measurement Range of ±40V (x1 file) and ±400V (x10 file), coupled with the included P6100 High Voltage Probe, allows the device to safely and accurately measure a broad spectrum of voltages. This versatility makes the FNIRSI 1C15 suitable for applications ranging from low-voltage embedded systems to higher-voltage power electronics, expanding its utility across diverse engineering disciplines.
