FNIRSI 2C23T portable 3-in-1 oscilloscope multimeter signal generatorThe FNIRSI 2C23T is a versatile 3-in-1 measurement tool that combines the functions of a dual-channel oscilloscope, precision multimeter and signal generator. With its compact design, intuitive operation and advanced features, it is an ideal choice for both professional and novice electronics engineers. The built-in 3000 mAh battery provides up to 8 hours of operation, and the 2.8" color screen with a resolution of 320 × 240 px allows for convenient readings in any conditions.Advanced oscilloscope with two channelsThe device offers a dual-channel oscilloscope with a 10 MHz bandwidth and 50 MS/s sampling rate. Each channel operates independently, which eliminates interference and increases measurement precision. Thanks to its well-thought-out hardware architecture (FPGA + ADC + MCU), the FNIRSI 2C23T perfectly reproduces even the finest details of signals. It supports auto, single and normal trigger modes, and allows you to adjust settings automatically - just one click to get a clear graph. You can save waveform snapshots and export them to a computer for easy later analysis.Multimeter with a wide range of applicationsThe multimeter's function allows accurate measurement of voltage (AC up to 750 V, DC up to 1000 V), current, resistance, capacitance, diodes, circuit continuity, as well as zero and phase wire recognition. True RMS measurement and automatic range selection ensure high accuracy and ease of use. Intelligent burnout protection (using ceramic fuses) protects the device and the user. Measurement data can be retained on the screen for easy reading and interpretation.Universal signal generatorThe built-in generator offers seven types of signals, including sine, rectangular, triangle, full-period, half-period, noise and DC. The output frequency ranges from 1 Hz to 2 MHz, and the amplitude from 0.1 to 3.3 V. The user can also adjust the fill factor from 0 to 100%. This is an ideal tool for testing electronic circuits and debugging circuits.Thoughtful design and convenience of useThe FNIRSI 2C23T is made of durable ABS material with an additional silicone cover for drop and shock resistance. The high-grade gold-coated PCB ensures better corrosion resistance and reliable operation. A convenient stand allows stable positioning on a table, and silicone buttons ensure comfortable operation. The USB-C port allows fast charging, and the ultra-thin design (just 3 cm thick) makes the device easy to fit in a bag or backpack.Use in many situationsThe FNIRSI 2C23T will prove useful both in the workshop and in the field. It can measure 220V mains voltage, analyze impulse signals, measure the carrier wave of quartz oscillators, evaluate the voltage ripple of power supplies and test audio signals. Support for five languages (English, Russian, Portuguese, Japanese, German) and software updates ensure the versatility and longevity of the equipment.Included oscilloscope 10X probe probe with crocodile clip probe with multimeter charging cable user manual General Manufacturer FNIRSI Model 2C23T Screen 2.8" HD color Screen resolution 320 x 240 Charging Via Type-C cable (5V/1A) Battery Lithium, 3000 mAh Features Oscilloscope, sound generator, multimeter Standby time 6 hours Supported languages English, Russian, Portuguese, Japanese, German Dimensions 167 x 89 x 35 mm Weight 300 g Oscilloscope Channel Dual channel Sampling frequency 50M Analog bandwidth 10M Memory 32kb Impedance 1MΩ Time base range 50ns-10s Vertical sensitivity 20mV/div-10V/div (X1) Maximum voltage 400 V Trigger mode Automatic, normal, single Trigger type Rising edge, falling edge Display mode YT/scroll Coupling method AC/DC Save waveform screenshots Supported Waveform viewing on computer Supported Sound generator Channel Single Frequency 1Hz-2MHz Amplitude 0.1-3.3V
