The FNIRSI 1014D is a portable 2-in-1 test instrument that combines a dual-channel digital oscilloscope with a built-in DDS signal generator. Featuring a 100MHz bandwidth and a real-time sampling rate of 1GSa/s, it provides accurate waveform analysis for electronics development, troubleshooting, and educational applications. The integrated signal generator supports multiple waveform outputs, while the 7-inch TFT display delivers clear visualization of signals and measurements. With onboard storage, advanced triggering functions, and input protection up to 400V when used with a 10× probe, the FNIRSI 1014D is a versatile tool for laboratory, workshop, and field use.
