A pre-owned Agilent N5225A PNA gives R &D and production teams wide 10 MHz-to-50 GHz coverage with 110 dB receiver dynamic range, revealing minute S-parameter variations in high-gain or high-loss fixtures. Ultra-low 0.002 dB trace noise keeps ripple below the "thickness of a hair," while fast 3.5 µs/point sweeps cut test time on filters, amplifiers and mixers.

The integrated two-port 2.4 mm test set supports TRL/LRM on-wafer calibration without extra hardware, and SCPI/LAN automation protects existing code investments. Refurbished units can ship ISO-17025-calibrated with current firmware, slashing capital expense and lead-time yet preserving Agilent reliability and future option upgrade paths.

• Laboratory-Verified Performance - Every unit ships with an ISO/IEC 17025 calibration certificate (TESTRO Certified) tied to its serial number.
• Full Internal Transparency - High-resolution teardown photos plus a live video test (gain-linearity, noise-floor, spurious response); recordings are stored for the product's lifetime.
• Warranty & Technical Support - One-year warranty and weekday remote assistance from the in-house engineering team for both software and hardware issues.
• Secure, Rapid Shipping - Aviation-grade flight case with triple-layer anti-vibration foam and shock/tilt indicators; priority DHL delivery in 3-5 days to major destinations.
• Flexible Payment Options - Accepts T/T, wire transfer, credit card.
• On-Site Inspection Welcome - Customers may visit the Shenzhen warehouse and refurbishment line to view calibration benches, burn-in racks, and inventory.
