Fnirsi 2C23T is an interesting combination of a multimeter and a digital oscilloscope with extensive functions and a DDS generator. All this has been enclosed in an ergonomic case perfectly lying in the hand. For its production, ABS was used, which is a durable plastic with high resistance to accidental mechanical damage. In addition, we all corners, as well as at the top and bottom of the housing were made special overflows of flexible silicone. Their task is to provide a secure grip, as well as protect the device in the event of a fall from a small height. Using the oscilloscope and the Fnirsi 2C23T multimeter is facilitated by the color LCD screen with a diagonal of 2,8 inches. Its resolution is 320 x 240 pixels, which in combination with high contrast allows fast reading in virtually any lighting conditions. The work is also facilitated by the built-in lithium battery with a capacity of 3 000 mAh, which allows you to carry out diagnostic activities anywhere. It can be charged using the USB type C connector, thus allowing you to forget about the need to buy relatively expensive 9 V or AAA batteries. Buttons used we Fnirsi 2C23T were made of soft and pleasant to the touch plastic. Operation of the device is also facilitated by a large, 4-position pad with a central function switch. It allows you to quickly navigate through the menu, allowing you to choose the mode of operation of the device, as well as providing convenient access to the configuration menu. Fnirsi 2C23T, used as an oscilloscope, provides the ability to test an analog band with a width of 10 MHz while maintaining a sampling frequency of 50 MSa/s. The maximum voltage of the analyzed signal is 400 V. Fnirsi 2C23T can work in three trigger modes – single, manual and automatic. Slope detection rising or falling. Signals can be saved and then exported to the computer using the USB-C cable. The integrated function generator can display 7 different waveforms of electrical signal, including sinusoidal, rectangular, triangular, full wave, half wave, noise and DC. The frequency of the output signal ranges from 1 Hz to 2 MHz. On the front of the Fnirsi 2C23T you can find traditional leads for multimeter probes, while in the upper part of the body there are two oscilloscope connectors along with the output of the DDS function generator. On the right side of the device, a Type-C USB port is placed in the middle.   Specification: Number of channels: 2; Sampling rate: 50 MSa/s; Voltage sensitivity: from 20mV to 10V; Time base adjustment range: 50ns to 10s; Possibility of safe operation with voltage up to 400V; Analog bandwidth: 10 MHz; Input Impedance: 1MΩ; True RMS measurement; Possibility of testing voltage, amperage, capacitance of capacitors, resistance, grounding, as well as diode testing; Maximum voltage measurement: AC up to 750 V / DC up to 1 000 V; Automatic selection of the measuring range;   USB interface for charging the oscilloscope; Built-in lithium battery with a capacity of 3 000 mAh for up to 8 hours of operation; Extendable leg allowing for stable positioning of equipment on the work surface; Physical dimensions: 167 mm x 89 mm x 35 mm; Included with the Fnirsi 2C23T digital oscilloscope is a USB type C cable, a probe, a set of probes and an instruction manual in English. 2-channel oscilloscope with multimeter and generator DDS 3in1 FNIRSI 2C23T
