Features and benefits

Why I love FNIRSI-1014D

Integrated DDS Function Signal Generator: This device boasts a built-in DDS signal generator supporting 14 standard function signals, including sine, square, triangle, sawtooth, and more, all with a precise 1Hz frequency step. The sine wave can reach frequencies up to 10MHz, while other standard signals extend to 2MHz, and the cut-off frequency also reaches 2MHz. This capability allows users to generate a wide array of test signals for various applications, from basic circuit testing to complex system diagnostics, offering unparalleled flexibility compared to devices with limited signal generation options.
Industry-Original Capture Output Function: A standout feature is the «Capture output» function, which allows users to intercept part or the entirety of complex signals measured by the oscilloscope and use them as the output signal for the signal generator. This unique capability can store up to 1000 customized signals, providing a significant advantage over traditional arbitrary signal generators that often suffer from subjective manual signal description and characteristic distortion. With a frequency adjustable from 1Hz to 1MHz (@ 2.4Vpp) and a resolution of 1Hz, this function is invaluable for replicating real-world signals for testing and analysis, a feature currently absent in most professional oscilloscopes or signal generators.
Intelligent Anti-Burning Protection and Robust Encoder Algorithm: The FNIRSI-1014D incorporates an intelligent anti-burning module on its two input channels, capable of tolerating up to 400V continuous voltage input. This eliminates the common concern of accidental oscilloscope damage when probes are not correctly set to the 10X position for high-voltage measurements. Furthermore, it features a targeted high-intelligence decoding algorithm designed to overcome the common issue of encoder (knob) wear and oxidation found in many desktop oscilloscopes, ensuring infinite encoder life and reliable operation even if the physical encoder degrades, thus extending the device’s lifespan and usability.
Dual-Channel Input with High Performance: Equipped with two input channels, each featuring a 1MΩ input impedance, the FNIRSI-1014D enables simultaneous measurement of two distinct signals. This dual-channel capability is crucial for comparative analysis, such as evaluating the input and output signals of an amplifier to determine its amplification factor, distortion, or output internal resistance, or testing complementary PWM signals in switching power supplies. This significantly broadens its application scope compared to single-channel devices, providing deeper insights into circuit behavior.
Efficient One-Button Automatic Adjustment and Comprehensive Triggering: The device simplifies operation with its «One-button AUTO» function, which automatically identifies signal characteristics and adaptively sets trigger levels (25%, 50%, 75%) within approximately 2 seconds for a 1V peak-to-peak signal, ensuring the waveform appears centered on the screen without tedious manual adjustments. Complementing this is a complete triggering function offering Single, Normal, and Auto modes, allowing users to effectively capture both periodic analog signals (Auto mode), aperiodic digital logic signals (Normal mode), and sudden aperiodic burst signals (Single mode), making it highly adaptable to a wide range of measurement scenarios.
Advanced Display, Measurement, and Storage Capabilities: The FNIRSI-1014D features a fully fitted 7-inch 800×480 resolution color TFT LCD display, offering bright colors and high contrast for clear waveform visualization. It supports up to 12 parameter measurements (VPP, VP, Vmax, Vmin, Vavg, Vrms, Frequent, Duty+, Duty-, Time+, Time-, Period) and includes a cursor measurement function for convenient manual reading of period, frequency, and voltage. With a built-in 1GB storage space, it can store up to 1000 screenshots and 1000 sets of waveform data, managed by a powerful image manager that supports thumbnail browsing, zooming, and moving, facilitating secondary analysis and documentation. The USB interface further allows easy sharing of screenshots with a computer.
Lissajous Figures and FFT Display: For advanced signal analysis, the oscilloscope includes Lissajous figures graphic display functionality, which is essential for comparing and judging the amplitude, frequency, and phase contrast of two groups of signals. Additionally, the FFT (Fast Fourier Transform) display function allows users to analyze the spectral characteristics of signals, providing insights into harmonic components and frequency content. These features, combined with memory compression technology for flicker-free waveform refresh and adjustable screen/grid brightness, enhance the analytical power and user experience of the FNIRSI-1014D.

Pros and Cons

Strengths & Weaknesses:

Efficient «One-button AUTO» adjustment for quick and accurate waveform display, typically within 2 seconds.
Complete trigger functions (Single, Normal, Auto) for versatile signal capture.
High 100MHz analog bandwidth and 1GSa/s real-time sampling rate for detailed signal acquisition.
Large 7-inch 800×480 color TFT LCD display provides clear and high-contrast waveform visualization.
Extensive measurement capabilities with 12 parameters and cursor measurement function.
Built-in 1GB storage for 1000 screenshots and 1000 waveform data sets, with a powerful image manager.

Points to Consider

Battery is included but not demountable, which might limit long-term serviceability or replacement options.
While powerful, the «Capture output» frequency range is limited to 1MHz, which might not cover all high-frequency custom signal generation needs.
The device is described as a «desktop» oscilloscope, but its compact size (340x140x70mm) and battery inclusion suggest it’s more portable, which could be a pro or con depending on user expectation.
Voltage accuracy is ±5%, which might be acceptable for general DIY and maintenance but could be a limitation for highly precise scientific or industrial applications.
The storage depth of 240Kbit (or 30KB record length) might be considered moderate for capturing very long, high-resolution waveforms compared to higher-end professional oscilloscopes.
