IINTERHARMONICS GROUP

If the Harmonics group is selected, the screen will appear as shown in Figure 9-26. The screen
has the following parameters that are unique to the group:

Figure 9-26: IEC 1000-4-13 INTERHARMONICS

1. LEVEL

Sets the percentage level of the inter harmonics relative to the fundamental.

The level is fixed for the entire frequency range defined by FRANGE. To

change levels, 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. An individual range step can be run by selecting the desired

range, followed by RUN RANGE from the RUN field.

3. STEP

The step size defines the inter harmonics sweep points. This step size is fixed

for the entire range of the sweep. The STEP size can be changed when the

test state is off.

4. IHFREQ

This field shows the current inter harmonic frequency when the test is running.

An inter harmonic frequency can be selected with the shuttle. To run an inter

harmonic frequency without sweeping through the entire range, RUN POINT

must be selected.

5. PAUSE

Sets the time in seconds for which the test will pause between inter harmonic

frequencies. There is only one value for the entire test. The PAUSE can be set

when the test is not running.

MEISTER CURVE GROUP

If the Meister curve group is selected, the screen will appear as shown in Figure 9-27. The
screen has the following parameters that are unique to the group:

Figure 9-27: IEC 61000-4-13 Meister Curve

1.

LEVEL

Sets the percentage level of the inter harmonics relative to the

fundamental. The level is fixed for the entire frequency range defined by FRANGE. To
change levels, 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. An individual range step can be run by selecting the
desired range, followed by RUN RANGE from the RUN field.

3.

STEP

The step size defines the inter harmonics sweep points. This step size is

fixed for the entire range of the sweep. The STEP size can be changed when the test
state is off.

4.

PAUSE

Sets the time in seconds for which the test will pause between ranges.

There is only one value for the entire test. The PAUSE can be set when the test is not
running. For the Meister curve test, the pause time is normally set to 0 secs. If a value
other than 0 is entered, the inter harmonics are set to 0% during the pause times.
