【Updated Designed USB Tester】FNB58 USB tester has a 2.0-inch full-color ultra-wide viewing angle TFT LCD display, integrated USB-A, Micro-USB, Type-C interface. It is a high-reliability, high-safety USB voltage andcurrent detection meter and a mobile communication terminal fast chargingtrigger. Gravity sensor, automatically switch the display direction. 【Multifunction USB Digital Tester】FNB58 uses external 16-bit ADC, PD protocol physical chip. It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks. FNB58 USB tester can monitor the voltage, current, power, resistance, capacity, temperature, D+/D- voltage etc, it can be used to test the fast charging protocol of chargers. 【Fast Charge Protocol Trigger Detection】FNB58 supports trigger detection of various fast charging protocols, QC2.0/QC3.0 trigger, FCP/SCP trigger, AFC trigger, PD2.0/3.0 trigger, VOOC/WARP trigger, Super VOOC 1.0/2.0 trigger. The above protocols all support automatic monitoring. MTK-PE automatic detection. Support QC2.O->PD2.0 protocol conversion. 【Parameter Detection and Recording】The highest six-digit display of voltage, current and power, the highest resolution is 0.00001 (V/A/W). 10 sets of switchable capacity, power and time statistics. 1 set of voltage and current curve records, maximum support 9 hours. Support low-speed waveform (voltage, current, D+/D-) drawing, 2sps->100sps sampling rate. Support high-speed ripple (voltage, AC coupling)drawing, up to 4M sps sampling rate. 【Other detection functions】FNB58 also has many functions that other USB testers do not have. The internal resistance measurement of the wire by the differential pressure method. E-Marker Cable chip reading. DASH Cable data reading. Record of startup time. Onboard temperature measurement. PD monitor. Analog DASH cable.
