Product description: FNIRSI 1014D - 2-channel digital oscilloscope 100 MHz 1 GSa/s with DDS generator
The FNIRSI 1014D is a 2-in-1 digital storage oscilloscope that combines the functions of a 2-channel oscilloscope with a DDS signal generator. The device offers a 100 MHz x2 analog bandwidth, 1 GSa/s real-time sampling rate, and a 7-inch color TFT LCD with 800 x 480 resolution. This makes it ideal for measurement, diagnostics, and signal analysis in electronics, service, automation, and DIY projects. The oscilloscope supports Auto, Normal, and Single trigger modes , AC/DC coupling, and cursor measurements , which facilitate peak-to-peak and frequency readings without manual recalculation. The built-in DDS generator allows you to create 14 standard signal types and a custom signal. The device also supports waveform recording, image export via USB, AUTO function, Roll mode, FFT view, and Lissajous plot presentation.

Built-in DDS signal generator
The FNIRSI 1014D features a built-in DDS function generator, allowing you to create test signals without the need for an additional device. The generator supports 14 standard 2.5 Vpp signal types, including sine, square, triangle, sawtooth, and other test waveforms. The sine wave frequency can reach up to 10 MHz, and the other signals up to 2 MHz.
The device also supports waveform recording, image export via USB, AUTO function, Roll mode, FFT view and Lissajous plot presentation.Convenient waveform analysis on a large screen
The large 7-inch TFT LCD screen with 800 x 480 px resolution provides a clear view of signals, settings, and measurement parameters. The AUTO function allows for quick measurement settings, which is useful when working with new or unfamiliar signals. Cursor measurement facilitates amplitude and frequency analysis, especially when automatic measurement may be hampered by noise or unusual waveforms.
Signal saving, exporting and comparison functions
The oscilloscope allows you to save screenshots and waveforms, making it easier to document measurements and analyze them later. USB export allows you to transfer saved images to a computer and use them in reports, service documentation, or educational materials. The Lissajous function allows you to compare two signals in terms of amplitude, frequency, and phase shift, while the FFT view helps you assess the frequency components of the signal being tested.

The oscilloscope allows you to save screenshots and waveforms, which makes it easier to document measurements and analyze them later.
