The pre-owned Agilent E8358A PNA delivers vector-network accuracy from 300 kHz to 9 GHz while its 128 dB dynamic range and sub-0.004 dB trace noise expose subtle S-parameter variations without external boosters. Fast 35 µs/point sweeps keep production throughput high, and built-in source attenuators, bias-tees, and direct-receiver access simplify TRL/LRM on-wafer calibrations.

Despite its 23 kg portable chassis, the analyzer offers SCPI/COM automation and USB-driven ECal support, making it a cost-effective, drop-in replacement that ships ISO-17025-calibrated and firmware-verified -- cutting capital expense and lead-time while retaining Agilent reliability and long-term serviceability.

• 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.
