## Summary description

Portable oscilloscope Fnirsi 2C53P with a 4.3" touchscreen and 3-in-1 functionality. Designed for on-the-go signal diagnostics, it combines oscilloscope, multimeter and signal generator features in a compact unit. Suitable for electronics troubleshooting, hobbyist projects and field measurements, offering convenient touchscreen control and portable operation.

## Long description

The FNIRSI 2C53P is a portable 3-in-1 test instrument that combines a two-channel oscilloscope, a digital multimeter and a DDS signal generator in a compact handheld enclosure with a 4.3-inch IPS touchscreen (480 × 272 px). It is intended for on-the-go signal diagnostics and measurement tasks where a small, battery-powered instrument with touchscreen control and basic PC connectivity is required.
Advantages
The device integrates oscilloscope, multimeter and generator functions in one unit, saving space and simplifying field work. A 4.3" color IPS touchscreen with tempered glass provides direct and intuitive control with zoom and pan for waveform viewing. Technical features include 50 MHz bandwidth, 250 MSa/s sampling rate, 12 selectable waveform types, True RMS measurement and FFT for basic spectral analysis. A 4000 mAh lithium battery and USB Type-C charging support extended portable use, while protective fuses and an impact-resistant housing increase operational safety.
Suitable for
Electronics troubleshooting and repair in workshops and field service
Testing and debugging switching power supplies and mains-related interference
Hobbyist and educational electronics projects
Audio signal inspection and pulse/signal analysis

How to use
Power the unit via the built-in lithium battery or Type-C supply. Select the required mode (oscilloscope, multimeter, or signal generator) from the touchscreen menu. For oscilloscope measurements connect the probe set to the input, choose probe attenuation (1×/10×) and set time base and vertical scale. Use auto set for quick waveform calibration or adjust trigger and coupling settings for stable display; use FFT or X-Y mode for advanced signal analysis. For multimeter measurements attach the appropriate probe leads and select measurement type; stored measurement parameters and min/max tracking can be reviewed on the screen. Use the signal generator to output test waveforms and adjust amplitude and frequency as needed. Save waveforms or export measurement data to a PC via the USB file transfer function.
Usage recommendations
Use the correct probe attenuation setting and input coupling for the measured signal, ensure protective fuses are intact before measuring high voltages, and enable the 20 MHz bandwidth limit when measuring low-level power supply noise. Charge the internal battery using the specified Type-C (5 V/2 A) supply and store the device in a dry, impact-protected environment when not in use.
