Does the operator need to force the auto alignment to ensure the X-Series (PXA/MXA/EXA/CXA) Signal Analyzer is meeting published specifications?

No, the factory power on configuration has the auto-alignment process turned on. With the auto-alignment turned on, background calibrations are being performed during the re-trace time of the sweep. Operators can turn the auto-alignment process off through the front panel, however certain analyzer parameters may degrade. Refer to the Specifications Guide for details.
