FNIRSI 2C23T: 3-in-1 Digital Oscilloscope, Multimeter & DDS Generator | 2 Channels, 10 MHz

Meet FNIRSI 2C23T: a 3-in-1 handheld lab companion

Designed for on site testing and classroom demos, the FNIRSI 2C23T blends a two-channel oscilloscope, a precise multimeter, and a versatile DDS signal generator into a compact handheld device. With 10 MHz bandwidth and 50 MSa/s sampling, you can capture clear waveforms and test signals across a range of projects without carrying multiple tools.

Key capabilities at a glance

• Oscilloscope mode with two channels, 10 MHz bandwidth, 50 MSa/s, and up to 400 V input
• Multimeter mode with 4-digit 10000 counts for AC/DC voltage, current, resistance, and capacitance
• Signal generator with up to 2 MHz output and seven waveforms including sine, square, triangle, DC, and more
• One-click save and easy waveform storage with export options for PC transfer

Smart measurements and data handling

Switch between modes quickly, compare reference waveforms with measured data on the same screen, and save results for later review. This helps engineers verify signals and track test steps without leaving the bench.

• One-click saving and waveform comparison on a single display
• PC compatibility via data cable for easy image upload and archival

Design that travels with you

Built on a robust FPGA plus MCU plus ADC architecture, the device includes a high voltage protection module and a bright 2.8 inch LCD. A built in 3000 mAh lithium battery supports hours of operation, and the unit stands ready for field work with up to six hours of standby.

Practical use scenarios

Ideal for electronics labs, repair technicians, hobbyists, and technicians performing on site diagnostics, bench testing, or classroom demonstrations. The compact form factor and versatile feature set help you explore circuits, confirm signal behavior, and document results with confidence.
