To address spectrum analysis result distortion in the Agilent N9010A MXA signal analyzer, you can check the following key components and aspects: 1. Input path components: Input attenuator (for damage or incorrect settings), preamplifier (gain stability verification), and RF mixer (linearity issues). 2. Local Oscillator (LO) system: Ensure LO frequency accuracy and phase noise are normal (LO instability causes distortion). 3. Intermediate Frequency (IF) section: Inspect IF filters (passband distortion/damage) and ADC module (proper digitization). 4. Calibration status: Confirm proper calibration (expired/incorrect calibration often leads to distortion).
