FNIRSI-1014D Two-in-One Digital Oscilloscope & Signal Generator

Product Introduction

The FNIRSI-1014D is a versatile two-in-one digital oscilloscope and signal generator from FNIRSI, offering comprehensive functions and high practicality. This cost-effective dual-channel desktop oscilloscope is designed for maintenance and R&D industries. It features a real-time sampling rate of 1GSa/s and 100MHz*2 analog bandwidth. The complete trigger function (single, normal, automatic) allows for free use with both periodic analog and aperiodic digital signals.

A built-in DDS function signal generator with an industry-original chopping output (@ 2.5VPP) supports 14 standard function signals and customizable chopping signals. The chopping output can intercept part or the whole of complex signals measured by the oscilloscope, storing up to 1000 customized cut-off signals.

The integrated high-voltage protection module tolerates up to 400V continuous voltage, preventing damage from incorrect probe settings. A large time-base scrolling mode monitors slow level changes. Efficient one-button auto, self-adaptive 25%, 50%, 75% trigger displays waveforms without complex adjustments. The device features a 7-inch 800x480 high-definition LCD screen and a cursor measurement function for direct amplitude and frequency readings.

Convenient screen capture and waveform storage are supported with 1GB internal space, allowing storage of up to 1000 screen capture pictures and 1000 groups of waveform data. The storage process is simple and fast. A powerful waveform image manager facilitates thumbnail browsing, viewing details, page turning, deletion, and waveform manipulation for secondary analysis. A USB interface enables sharing screen captures with a computer. Lissajous graphic display compares and judges amplitude, frequency, and phase of two signals, while FFT viewing estimates harmonic components.
