Universal Counting Architecture
Features "Multi-Channel + High-Speed Processing" architecture: Dual 225MHz base channels (input sensitivity≤25mVrms, based on frequency counter standards), optional 12.4GHz RF input (phase noise≤-130dBc/Hz@10GHz, based on RF counter parameters), 500ps time interval resolution (measurement uncertainty±1.5ps, based on instrument specifications), GPIB interface for automated test integration (transfer rate>1MB/s, product feature description), limit testing functionality for pass/fail verification (test execution time≤100ms, product core feature).

Oscillator Validation Workflow
Connect: RF output to 12.4GHz input channel
Configure: Set frequency range and resolution
Measure: 10 digits/sec counting with auto-limit test
Analyze: GPIB output to test automation system
High-Frequency Measurement Boundary
When measuring >10GHz signals, thermal drift may cause ±2ppm frequency error (based on RF counter characteristics). Mitigation: ① Enable internal temperature compensation (accuracy improves to ±0.5ppm); ② Use external reference oscillator (lease accessory available).
