This helps the channel grow and allows us to invest in new products to show you. Comprehensive technical review of the Fnirsi FNB-C2, an analyzer specializing in the USB PD 3.1 Extended Power Range (EPR) standard up to 240W. We analyze its architecture with an external 20-bit ADC, the accuracy of the 10 mΩ shunt resistor, and its ability to capture PD packets and analyze ripple up to 2 MHz using FFT for advanced hardware diagnostics. Implementation and handshake of the USB Power Delivery 3.1 (EPR) standard. Acquisition architecture: Analysis of the 7-digit resolution and quantization of the 20-bit ADC. Power integrity monitoring: Visualization of VBUS waveforms and detection of switching noise. Interconnect Physics: Reading E-Marker chips and verifying thermal and current limits on cables. Teardown and Component Analysis: Evaluation of the internal power stage and heat dissipation management in the CNC chassis. [00:00] Context of the evolution of Fnirsi's USB instrumentation and transition to the metal chassis. [01:01] Hardware Specifications: The 20-bit ADC and the 50V / 6.5A / 240W limits. [01:51] Physical interface and driver-free HID connectivity for PC monitoring. [02:40] Dynamic Testing: Real-time flow direction detection and load consumption. [04:05] Protocol Analysis: Automatic scanning of PD, QC 3.0, AFC, and Huawei. [06:01] Cable Validation: Decoding E-Marker chip registers (AWG, Voltage, Current). [07:18] Signal Integrity: Ripple monitoring and spectral analysis using FFT up to 2 MHz. [08:31] Protocol Injection: PD Trigger, AVS profile negotiation, and handshake verification. [10:53] Internal Engineering (Teardown): 10 mR precision shunt and PCB topology. [13:01] Software Ecosystem: Professional data logging and export for efficiency analysis.
