9.5.4.2  IEC GROUPS  
This section will describe the groups and parameters associated with IEC 1000-4-13. Refer to 
paragraph 9.5.4.1 for groups associated with the test. 
FCURVE GROUP   
If the FCURVE group is selected, the screen will appear as shown in Figure 9-22. The screen 
has the following parameters that are unique to the group:

1.  LEVEL  Set the Flat curve clip level. This field can be set when the IEC 1000-4-13 is in 
    the OFF state and the Class is set for USER class. 
2.  PAUSE  Time in seconds the test will pause prior to proceeding to the following test. This 
    field can be set at any time when the test is not running. 
OSWING GROUP 
If the OSWING group is selected, the screen will appear as shown in Figure 9-23. The screen 
has the following parameters that are unique to the group:

1.  LEVEL  The level of the harmonics relative to the fundamental in percent.  There are 
    two levels, one for harmonic #3 and the other for harmonic #5.  The harmonic 
    number must be selected prior to the harmonic level entry.  To change levels, 
    the test state must be off and USER class must be selected. 
2.  HARM NO  There are only two harmonic numbers. This field is used to set the harmonics 
    level that corresponds to the harmonics number. 
3.  PHASE  Sets the phase angle of the harmonics relative to the fundamental.  The phase 
    can be set when the test state is off and USER class is selected. 
4.  PAUSE  Sets the time in seconds.  The test will pause prior to proceeding to the  
    following test. This field may be changed at any time as long as the test is not 
    running.
