SWEEP GROUP
If the SWEEP group is selected, the screen will appear as shown in Figure 9-28. The screen has
the following parameters that are unique to the group:
Figure 9-28: IEC 61000-4-13 Sweep
1. LEVEL Sets the percentage level of the inter harmonics relative to the fundamental.
The level is fixed for the entire frequency range, which is defined by
FRANGE. To change level, the test state must be off and user class must be
selected.
2. FRANGE The range is selected by rotating the shuttle. The range selection is required
to change the level for the selected range. Also, an individual range sweep
is possible by selecting the desired range and selecting RUN RANGE from
the RUN field.
3. STEP The step size defines the inter harmonics sweep points. Step size is fixed for
the entire sweep range. The STEP size can be changed when the test state
is off.
4. IHFREQ This field will show the current inter harmonic frequency when the test is
running. An inter harmonic frequency can be selected using the shuttle. To
run a frequency without sweeping through the entire range, a RUN POINT
can be selected.
5. RESONANT This field is used to report the resonant points, if any, after running the sweep
test. No editing is allowed in this field. When the test is completed, a display
of harmonics current versus frequency plot is available. To view the graph,
select the field and press the ENTER key.
