The FNIRSI 2C53T is a portable oscilloscope-multimeter-signal generator that combines the functions of a 2×50 MHz/250 MSa/s oscilloscope with an 8-bit ADC and 16 kpoint memory buffer per channel. It provides DC/AC measurement capability with up to 19999 counts and a 50 kHz signal generator.

The product features:

• Input impedance: 1 MΩ ∥ 15 pF with AC/DC/GND switching
• Display: 2.8-inch, 320×240 px resolution, with “infinite persistence” capability
• Battery: 3000 mAh, up to 4 hours of operation
• Certification: CAT II 300 V, dual ceramic fuses, and overvoltage protection circuit

The display shows waveforms in full color and includes Y–T, Rolling, and X–Y modes for phase difference analysis. The built-in multimeter supports voltage, current, resistance, and temperature measurements, with a durable ABS and silicone construction for increased durability.
