FNIRSI 2C23T / 2C53T Handheld Digital Oscilloscope Multimeter Signal Generator-

About this deal

The FNIRSI 2C23T and 2C53T are compact 3-in-1 handheld devices that combine a dual-channel oscilloscope, a multimeter, and a DDS signal generator in a single unit, making them well suited to electronics professionals, field technicians, students, and hobbyists. The 2C23T offers a 10 MHz bandwidth and 50 MS/s sampling rate with a 4-digit 10,000-count multimeter and a signal generator producing up to 7 waveform types at up to 2 MHz, while the upgraded 2C53T steps up to 50 MHz bandwidth, 250 MS/s sampling, a 4.5-digit 19,999-count multimeter, and 13 waveform types at up to 50 kHz. Both models feature FPGA-based hardware architecture with built-in high-voltage protection rated to +/-400 V peak, a 2.8-inch 320x240 colour display, and a 3,000 mAh rechargeable battery providing up to 6 hours of use. The 2C53T is the newer model, adding math operations, cursor measurement, persistence mode, and XY mode over the 2C23T. Waveform screenshots can be saved with a single button press and exported to a computer via USB-C for further analysis.
