FNIRSI 2C53P/2C23T Digital Oscilloscope Multimeter Signal Generator Dual Channel

About this deal

This listing covers two related but distinct models, so the description covers both clearly. The FNIRSI 2C53P is a dual-channel digital oscilloscope with three core functions in one handheld unit. The oscilloscope uses FPGA+MCU+ADC hardware architecture, offers a 250MS/s sampling rate and 50MHz analog bandwidth, and supports peak voltage measurements up to +/-400V. The built-in multimeter is a 4.5-digit, 19999-count true RMS unit supporting AC and DC voltage and current measurements. The DDS signal generator outputs 12 types of function signals up to 10MHz with adjustable frequency, amplitude, and duty cycle, all displayed on a 4.3-inch 480x272 touch screen backed by a 4000mAh battery for up to four hours of use. The FNIRSI 2C23T is the earlier model in this range, also a 3-in-1 dual-channel device combining an oscilloscope, multimeter, and signal generator. Its oscilloscope delivers 10MHz bandwidth and a 50MSa/s sampling rate with a maximum measurable peak voltage of +/-400V. The multimeter offers 4-digit, 10,000-count true RMS measurement covering AC/DC voltage and current, resistance, capacitance, and continuity. It uses a 2.8-inch 320x240 LCD display with a built-in 3000mAh battery providing up to six hours of standby. Both models suit electronics engineers, technicians, students, and hobbyists who need a portable, multi-function bench tool.
