## Summary description

Portable Fnirsi 2C23T combines an oscilloscope, multimeter and signal generator in one handheld unit. It offers 20 MHz bandwidth and 100 MSa/s sampling rate for waveform viewing, basic electrical measurements and test signal output. Designed for field diagnostics, electronics repair and hobby projects, it provides compact, battery-powered convenience and multifunction testing capability.

## Long description

The FNIRSI 2C23T is a compact 3-in-1 measurement instrument combining a dual-channel oscilloscope, a precision multimeter and a signal generator in a single handheld unit. It is powered by an internal lithium battery and features a 2.8" color display with 320 × 240 resolution, a USB-C charging port and a silicone-covered ABS housing with a fold-out stand for stable tabletop use.
Advantages
The device integrates oscilloscope, multimeter and signal generator functions in one portable enclosure, enabling quick switching between measurement modes. Independent dual oscilloscope channels, a hardware architecture based on FPGA + ADC + MCU, and support for automatic and single-shot triggering allow accurate capture of transient and periodic signals. The multimeter provides True RMS measurements with automatic range selection and protection via ceramic fuses. The built-in signal generator produces several waveform types across a wide frequency and amplitude range. Durable construction, gold-coated PCB, silicone buttons and a compact form factor improve reliability and ease of use in workshop and field conditions.
Suitable for
Field diagnostics and electronics repair
Hobbyist and educational electronics projects
Testing power supplies and measuring voltage ripple
Analyzing impulse and oscillator signals

How to use
Charge the device via the USB-C port before use. Select the required measurement mode (oscilloscope, multimeter or signal generator) using the device controls, then connect probes or test leads to the appropriate input terminals. For oscilloscope measurements, attach the probe to the signal source, set channel coupling (AC/DC), adjust the time base and vertical sensitivity, and choose a trigger mode (auto, normal or single) to obtain a stable waveform. For multimeter functions, use the multimeter probe and select the parameter to measure; observe range, polarity and hold options on screen. For signal generation, choose waveform type, set frequency and amplitude, and connect the generator output to the circuit under test. Save waveform screenshots or export data to a computer when needed for later analysis.
Usage recommendations
Use the supplied 10× oscilloscope probe for high-voltage or high-frequency measurements to maintain accuracy. Observe input voltage limits and fuse protection when measuring mains or high-voltage circuits. Keep the device and probes clean and dry, and store with the silicone cover in place to reduce the risk of impact damage. Update device firmware when updates are available to maintain language support and feature improvements.
