SWEEP GROUP

If the SWEEP group is selected, the screen will appear as shown in Figure 9-24. The screen
has the following parameters that are unique to the group:

Figure 9-24: IEC 1000-4-13 SWEEP

1. LEVEL

Sets the percentage level of the interharmonics 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 interharmonics 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 interharmonic frequency when the test is

running. An interharmonic 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.

HARMONICS GROUP

If the Harmonics group is selected, the screen will appear as shown in Figure 9-25. The screen
has the following parameters that are unique to the group:

Figure 9-25: IEC 1000-4-13 Harmonics

1. LEVEL

Sets the percentage level of the harmonic relative to the fundamental. Each

level is associated with a harmonic number. To change levels, the test state

must be off and user class must be selected.

2. HARM NO Selecting a harmonic number using the shuttle knob will allow examination of

the LEVEL and PHASE of each harmonic and changing the level and phase

angle when USER class is selected.

3. PHASE

Sets the phase angle of the harmonics relative to the fundamental. To change

phase, the test state must be off and user class must be selected.

4. PAUSE

Sets the pause time in seconds between harmonics tests. There is only one

value for the entire test. The PAUSE value can be changed when the test is not

running.
