The FNB58 USB tester features a 2.0-inch full-color TFT LCD display with an ultra-wide viewing angle, and includes USB-A, Micro-USB, and Type-C interfaces for reliable voltage and current detection.
This multifunctional USB digital tester employs a 16-bit ADC and PD protocol chip, allowing it to measure power supply and consumption for devices like USB interfaces, chargers, and flash drives.
The FNB58 USB tester can effectively monitor voltage, current, power, resistance, capacity, temperature, and D+/D- voltage, making it ideal for testing fast charging protocols of various chargers.
It supports trigger detection for multiple fast charging protocols, including QC2.0/QC3.0, FCP/SCP, AFC, PD2.0/3.0, and VOOC/WARP, with automatic monitoring for all listed protocols.
The device allows for low-speed waveform drawing (voltage, current, D+/D-) with a sampling rate from 2sps to 100sps, and high-speed ripple drawing (voltage, AC coupling) at up to 4M sps sampling rate.
