Repair
Repair by the user is not recommended because of the complex
equipment required for test and calibration.
Returning a Noise Source for Calibration
When returning a 346 or Noise Source to Agilent Technologies for repair
or calibration, please specify whether an ENR Data Diskette is needed.
When the 346 is used with an Agilent Noise Figure Analyzer NFA, the
ENR Data Diskette is used to automatically load the ENR values into
memory.
When the 346 is used with an 8970A/B Noise Figure Meter, you must
enter the ENR values manually, and the ENR Data Diskette is not
necessary.
