FNIRSI DSO2C53P 3-in-1 Tablet Oscilloscope 50MHz 2CH Touch Display-Portable

The FNIRSI DSO2C53P is a powerful 3-in-1 portable test instrument that combines a dual-channel digital oscilloscope, high-precision multimeter, and DDS signal generator into a compact tablet-style device. Designed for engineers, technicians, and electronics enthusiasts, it offers advanced measurement capabilities while remaining portable and easy to use.

Equipped with a 4.3-inch IPS touch display (480 × 272 resolution), the device provides clear waveform visualization and intuitive touch control. The oscilloscope delivers 50MHz bandwidth and a 250MSa/s real-time sampling rate, allowing accurate signal capture for both analog and digital circuits. With support for AUTO, Normal, and Single trigger modes, users can quickly capture and analyze signals in real time.

The integrated DDS signal generator outputs up to 12 different waveforms with frequencies up to 10MHz, making it ideal for circuit testing, debugging, and signal simulation. The built-in multimeter with 19999 counts supports voltage, current, resistance, capacitance, and temperature measurements, making the device a versatile diagnostic tool for a wide range of electronic applications.

Advanced analysis tools such as FFT spectrum analysis and X-Y waveform comparison allow detailed signal evaluation, including phase, amplitude, and harmonic content. Powered by a 4000mAh rechargeable battery, the DSO2C53P offers up to 4 hours of portable operation, while USB Type-C charging ensures convenient power and data connectivity.

Combining multiple essential testing tools into a single handheld device, the FNIRSI DSO2C53P is ideal for electronics troubleshooting, circuit design, education, and field service work.
