AMETEK MX CTSH - Manual (Page 96)

California Instruments Revision H 96
User Manual MX Series CTSH Compliance Test System
The EN 61000-4-13 test suite consists of four types of tests:
Test type Description
Flat top Curve Simulates specific waveform at the nominal voltage and frequency
Over Swing 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 &
Inter harmonics 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
Over Swing 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
Inter harmonics: Dwell time = 5 sec (per harmonic) * 40 = 200 sec
Pause time = 1 sec (per harmonic) * 40 = 40 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 MXGUI 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 Over Swing test steps are selected in the Test
Setup tab.
