Page 2 Service Note E7402A-02
To Be Performed By: Agilent-Qualified Personnel
Situation:
Instruments leaving the factory can fail the Low Frequency Response specification less than
50kHz. Manufacturing discovered a software problem where incorrect low frequency flatness
correction values were being loaded into the instrument memory.
Solution / Action:
As of January 7th, 2000, the Field Software for the E7400A-series EMC Analyzers IS NOT
AVAILABLE at the CSC’s. If a customer sends in an E7400A-series EMC Analyzer for this
specific problem, the analyzer will have to be sent back to the Factory for re-alignment.
When the Field Software becomes available, and an E7400A-series EMC Analyzer is sent in for
this problem, the following should be done:
Perform the Frequency Response Test using the automated software, or run the test manually as
per the E7400A-series EMC Analyzer Calibration Guide. If the test fails, you will need to load
new flatness correction values into the analyzer using the Adjustment Software.
