Battery Simulation Testing — Simulates voltage transients and peak current output (Based on parameter adaptability)
Leasing Scenario Technical Adaptation
Short-Term Project Deployment — Dual-channel control reduces equipment count, preset battery test templates (e.g., Li-ion charge/discharge curve), setup in 5 minutes
Multi-Model Compatibility — Data format compatibility with 66300 series (e.g., 66311B/66312A), no recalibration needed
Technical Deep Dive
Core Technology Architecture
Features "Dual Independent PWM Control + High-Speed Feedback" architecture: 16-bit DAC per channel enables 0.05% voltage programming (Source: Keysight 66319D whitepaper), built-in current sensing supports 5A peak output (7ms duration), <20μs feedback response ensures voltage stability during load transients (≤40mV droop). Integrated DVM function provides 0.03%+5mV readback accuracy via high-precision ADC (Based on DC power supply standards).
| Technical Dimension | 66319D | Competitor (Tektronix 2230G-30-3) | Comparison Source |
|---|---|---|---|
| Channel Independence | Fully independent control (dedicated feedback) | Shared power module (>100mV crosstalk) | Official technical descriptions |
| Transient Response | <20μs (40mV droop) | 50μs (100mV droop) | RS Components model comparison |
Mobile Device Battery Test Workflow
Connection: Dual outputs to main battery and charger inputs, GPIB interface to test system (90% of leasing use cases)
Configuration: Load "Smartphone Battery Test" preset → Channel 1: 4.2V/1A (battery sim), Channel 2: 5V/2A (charger input), setup in 30 seconds
Analysis: Real-time monitoring of discharge current (captures 5A@7ms peaks), DVM records voltage fluctuations (1mV resolution)
Output: USB export charge/discharge curves (CSV format), Excel-compatible analysis templates
Technical Usage Boundaries
When peak current duration >7ms, output current auto-limits to 3A (Source: Keysight 66319D FAQ). Mitigation: ① Stagger peak current applications (100ms intervals); ② Use external power booster module for continuous 5A output (<1% accuracy loss).
