Product Overview:

Bidirectional voltage and current monitoring – Real-time monitoring of D+ and D- voltages. PD message parsing enables detection of the currently active PD protocol profile.

PD and QC protocol spoofing – Supports QC2.0, QC3.0, PD3.0 (Fixed Voltage and PPS), as well as PD3.1 (EPR and AVS) negotiation simulation for flexible charging testing.

Software-based coulomb counter – Accurately calculates charging capacity. Innovatively applies different current integration scaling factors for different voltage levels, significantly improving accuracy when measuring charge capacity for devices using charge-pump fast charging (common in modern smartphones).

NTC temperature monitoring on shunt resistor – Enables real-time temperature drift calibration of the current sensing resistor for improved measurement precision under varying thermal conditions.

Comprehensive PD protocol packet capture and analysis – Features full PD logic packet logging and analysis capabilities. Monitors power source PDOs (Power Data Objects), displays the currently requested RDO (Request Data Object) in real time, records all communication packets, and stores and decodes commonly used PD messages.

Emarker simulation – Emulates E-marker functionality without requiring an actual data cable, enabling direct negotiation of 5A current and PD3.1 protocols with the charger. Can spoof proprietary cables, allowing handshake with private fast-charging protocols (e.g., on smartphones) without the need for original OEM cables. 5MHz ripple sampling capability – Supports multiple adjustable sampling rates. Performs FFT analysis to calculate ripple amplitude at relevant frequencies and generates an FFT spectrum graph for visualizing frequency distribution of the ripple.

Supports independent power supply via HID base board – Eliminates interference caused by the meter’s own power source, ensuring cleaner and more accurate measurements.

Compatible with Kelvin cable resistance measurement board – Enables precise measurement of cable resistance using a four-wire Kelvin sensing method.
