Outward Appearance and Internal Structure:
The 99094 emulator comes equipped with four channels, each designed to simulate quick charge control signals and voltage combinations. Each channel features a 15-pin interface connector supporting high-throughput production line testing with dual A/B test fixture switching. These connectors are vital for performing accurate tests on quick-charging devices in mass-production environments.
Testing Capabilities and Features:
Comprehensive Protocol Support: This emulator is fully capable of handling various quick charge standards such as Quick Charge 2.0 and 3.0, Pump Express, PE+ 2.0, and USB PD, making it suitable for a broad range of quick charging devices.
Quick Charge 2.0 & 3.0: For QC2.0, the system simulates multiple voltage levels (5V, 9V, 12V, and 20V) and automatically adjusts output based on D+/D- signals to ensure chargers comply with Qualcomm’s fast-charging specifications. In QC3.0, it supports finer voltage increments of 0.2V, which further enhances charging efficiency and reduces heat generation.
Pump Express (PE) and PE+ 2.0: Supporting MediaTek’s Pump Express protocols, the 99094 can emulate commands that allow precise voltage and current control, offering dynamic voltage adjustment similar to QC3.0. This is critical for reducing charging time while managing heat dissipation.
USB Power Delivery (USB PD): The emulator incorporates support for the USB-PD standard, allowing it to deliver up to 100W (20V @ 5A) of power, suitable for a wide range of devices with varying power needs.
Application and System Integration:
The 6010 ATE (Automatic Test Equipment) solution integrates the 99094 emulator to provide robust testing for various Quick Charger technologies. It can simultaneously control four charger channels, making it ideal for testing multiple products in parallel on production lines.
Pin Assignments:
Each of the four channels in the 99094 emulator features the following key pin configurations:
Pin 1-15: These pins include connections for VBUS, D+, D-, and Control signals (CHA and CHB), supporting dual-channel testing. This configuration ensures optimal control over testing protocols for different quick charging standards.
Advanced Testing Solutions:
High-speed Simulation: The 99094 enables high-speed simulation of quick charge protocols, facilitating rapid testing cycles essential for modern production environments.
Voltage and Current Control: With capabilities to adjust output voltages dynamically, the system supports both continuous mode ramping and step voltage adjustments. This flexibility ensures that all charger types, from basic 5V chargers to advanced 20V Quick Chargers, can be tested for compliance with the relevant specifications.
Key Technical Data:
