Scenario Deep Dive
Core Technical Logic
Features "Multi-Port Matrix Architecture + Low-Loss RF Path" design: N×M matrix switch enables flexible connection between N tester ports and M DUTs (e.g., 8×16 matrix supports 8 testers simultaneously testing 16 devices), RF path insertion loss <0.5dB (ensures signal integrity), control unit response time <10ms (supports high-speed switching) (Based on R&S CMWS series technical documentation).
Smartphone Production Line Test Workflow
System Setup: CMWS matrix switch input connects to 4 R&S®CMW100 (8 ports each), output connects to 32 smartphone DUTs, LAN interface integrates with MES system (60% fewer devices than point-to-point connection)
Switching Control: Automation script sends SCPI commands "ROUTE:CONNECT 1,1; 1,2;..." → synchronously assigns tester ports to DUTs, switching time <50ms
Parallel Testing: 32 smartphones simultaneously perform RF calibration (power/frequency error measurement), matrix switch monitors link status, auto-switches to backup channel on failure
Result Aggregation: Auto-disconnects after testing, data aggregated via MES system, switching efficiency increased 8x over traditional methods
Technical Adaptation Key Points
Matrix scale selection should match tester/DUT count (e.g., 16×32 for medium-volume production). For high-frequency testing (>6GHz), consider switch frequency response (recommend models supporting up to 18GHz). Automation scripts should optimize switching logic to prevent channel conflicts (predefined routing tables enable efficient scheduling).
