After repairing the port fault of Agilent PNA network analyzer, you can verify its performance recovery through the following steps: 1. Basic Function Check: Confirm the port has normal response (no no-output or low-output issues) and the instrument starts up without abnormal prompts. 2. Standard Calibration: Use calibration kits (open, short, match loads) to calibrate the port as per the instrument's procedure to ensure measurement accuracy. 3. Performance Index Testing: Verify key indicators like output power, harmonic distortion (e.g., ~-60 dBc), background noise (e.g., ~-110 dBm), and scan speed meet factory specs. 4. Functional Validation: Conduct S-parameter measurement to confirm the port delivers accurate and stable results.
