8.2 Tab Controls
The IEC 1000-4-13 Harmonics and Interharmonics test offers range of sub-tests and user
options. We recommend you familiarize yourself with the actual standard document. IEC
standards are available through
www.iec.ch .
The following help screens contain information on setting test options using the available 413 tab
controls located along the top of the IEC 1000-4-13 test window.
Tab Description
Test Setup User selected test options, EUT classes and test steps
Waveforms Flat top curve and Over swing curve definitions
Test Levels Sweep frequency ranges and test levels
Voltage Distortion AC Source voltage distortion monitor display
Waveform Display AC Source measured output waveform display
Resonance Points EUT current as a function of frequency and resonance point summary.
The buttons on the left-hand side of the window may be used to start and stop a test run and print
a test report.
Test parameters for Class X EUT's may be stored on and loaded from disk. This can be done
using the File, Save and File, Open menus.
The results of a frequency sweep may be saved to disk for later recall as well. Data files have a
.dat extension to distinguish them from a test setup file. (.413 extension) The Load and Save
Data entries in the File menu are used for this purpose.
8.3 Test Setup
The Test Setup Tab contains several controls that allow the user to configure the IEC 61000-4-13
test to be run on the EUT. The various settings are as follows:
Parameter Description
Phase mode The available phase mode is shown in the top right corner and cannot be
changed. For single-phase systems, phase A is always used as it is the only
phase. For three phase systems, all stimuli are applied to all three phases.
EUT EMC Class The test standard distinguishes between four classes of EUT, class 1 through 3
and a user defined class X. The user must select class 1, 2, 3 or X. Class X
levels can be set in the Test levels Tab but must be equal than or higher than
class 3 levels.
Nominal Settings These values are normally obtained from the AC source's steady state setting
when the test window is opened. They can be changed before running a test if
needed. Note however than frequencies other than 50 or 60 Hz are not covered
by the test standard.
Test Step Selection There are four main test categories that may be selected. Consult the test
standard for details on each step. Any combination of these four choices can be
made.
Test Options Prompt for EUT status: When checked, the program will prompt the operator for
a Pass or Fail determination after each test step selected in the Test Step
Selection box has been run. If this option is turned off, all test will be run and
this dialog will only appear when all test are completed.
IEC 725 Reference Impedance: If needed, the IEC 725 Flicker reference
impedance may be used during the IEC 61000-4-13 test. When this option is
checked, the iX Series will use its programmable impedance to implement the
required reference impedance. Note that this capability may not be supported
on all iX Series configurations.
Voltage THD: When checked, the test program performs an AC Source voltage
