The IEC 61000-4-13 test suite consists of five types of tests:
Test type Description
Flat top Curve Simulates specific waveform at the nominal voltage and frequency
OverSwing Curve Simulates specific waveform at the nominal voltage and frequency
Frequency Sweep Simulates frequency swept or stepped at a rate no less than 5 minutes per
decade
Individual harmonics &
Interharmonics Simulates sinusoidal voltage superimposed on the fundamental voltage for
5 second at each frequency in a range from 2X to 40X fundamental.
Meister Curve Special frequency sweep test to be used in countries where mains signaling
and /or ripple control is applied.
The user must select the desired EMC Class and test type before executing the test. If choosing
class X, the user can change any parameters but the levels have to be at least as high as those
for Class 2.
The total test time using the default dwell times are as follows:
Test Step Test Time
Flat Top Curve test: Dwell time = 120 sec
Pause time = 5 sec
OverSwing Curve test: Dwell time = 120 sec
Pause time = 5 sec
Frequency Sweep test: Dwell time = 300 sec (per decade) *2.5 = 750 sec
Individual harmonics: Dwell time = 5 sec (per harmonic) * 40 = 200 sec
Pause time = 1 sec (per harmonic * 40 = 40 sec
Interharmonics: Dwell time = 5 sec (per harmonic) * 147 = 735 sec
Pause time = 1 sec (per harmonic) * 147 = 147 sec
Meister Curve: Dwell time = 10 sec (per frequency step) * 147 = 1470 sec
Pause time = 0 sec
Changes made to dwell times and test levels can be saved using the File, Save menu.
There are two .413 files distributed with the CIGui32 or CIGuiSII program. The Class2.413 and
Class3.413 files are read-only files and can not be edited or changed. These files contain all
parameters, which are determined by the product standard. When changing the Dwell and Pause
times for Class 2 or Class 3, the user has to save the file under a different name.
8.4.1 Test Waveform Settings
The Waveforms Tab may be used to preview the Class 2 and Class 3 Flat top and Overswing
waveforms. For class X, the waveform parameters may be entered in the controls to the left of
the waveform display. Dwell times and pause times may be set for all classes.
Note that this Tab is only relevant if either the Flat Top or Overswing test steps are selected in the
Test Setup tab.
8.4.2 Test Level Settings
The Test Levels Tab may be used to preview the Class 2 and Class 3 frequency ranges and test
levels. For class X, this information may be edited. Dwell times and pause times may be set for
all classes. The following minimum and maximum values (in seconds) for dwell and pause times
apply. Note that these values are queried from the AC source if present and may change if the
firmware on the AC source is updated. As default, these times are set to their minimum values.
