Keep your refurbished bench analyzer running predictably by incorporating these routines into your facility's regular checkups:
The A2 uses an automatic gain control (AGC) loop with attenuators and amplifiers to scale incoming signals to an optimal level for the internal A/D converters and detectors. If an input FET or switching transistor fails, the logic controller will constantly switch ranges back and forth, unable to find the correct window.

Use your DMM to check the test points on the power supply board.
Once your hardware fixes are applied, power on the unit and run the internal self-test sequence. Connect the generator outputs directly to the analyzer inputs using high-quality shielded cables. Verify that the residual noise floor, frequency response, and THD readings match the original factory specifications.
