Class Determination

The following flowcharts document the class determination used by the Agilent 14761A HFTS software.
Class determination is a function of the Pre-test. The flowcharts illustrate
ñthe class determination process according to the device class that was selected in the Standard
Options window
ñhow a test is flagged as non-compliant based on class selection
ñhow the pre-test limits are calculated.
The A, B, C, and D class determination flowcharts are only valid for IEC 1000-2-2/EN 61000-2-2 Quasi-
stationary harmonics.
The last flowchart in the series documents the class determination used for the older EN 60555 Part 2
(IEC 555-2) regulation. This regulation is selected in the Options menu, under Defaults.
