8.6 Measurements
The following measurements are performed during the IEC 1000-4-13 test run.
8.6.1 Voltage Distortion Check
This is a data display Tab only. When selected in the test options, this Tab display the voltage
distortion of the AC voltage supplied by the AC Source as measured at the EUT. The individual
voltage harmonics must be below the IEC test standard levels set forth in IEC 61000-4-13. The
test software checks against these limits and displays a PASS or FAIL result in both the Test
Setup Tab and this Tab.
The result of the V THD check is included in the IEC 61000-4-13 Test report. Test results may be
printed to the default Windows printer using the print button or the File, Print menu.
8.6.2 Voltage Waveform Time Domain
This Tab displays the voltage waveform as captured at the EUT by the iX Series' data acquisition
system. This information is updated every couple of seconds and allows the user to monitor the
stimulus applied to the EUT. This TAB is only used for display purposes and contains no user
controls.
8.6.3 Resonance Points
During the test run, the voltage waveform is captured and displayed in the Waveform display Tab
page. This allows the user to determine if the EUT continues to operate. There may be effects on
the EUT such as reboots or processor lockups that cannot be seen by observing the EUT load
current. Frequency is not measured as it remains at the nominal frequency specified.
The resonance points Tab displays the EUT current as a function of the harmonic and
interharmonic frequencies applied to the EUT during the test. This information is displayed both
numerically in the table on the left and graphically in the chart on the right. Those points that meet
the criteria for a resonance point are listed in the table directly below the graph. Note that there
may not be any resonance points on a given EUT. In that case, this table will be empty. The total
number of resonance points found is shown between the graph and the resonance point table.
The are no user controls or settings on this Tab as it is used for data display only. Test results
may be printed to the default Windows printer using the print button or the File, Print menu.
8.7 IEC 61000-4-13 Test Reports
The IEC 61000-4-13 test module produces a test report when the Print Report button is clicked.
Reports can also be printed from the File, Print menu. Test reports include all selected test
parameters and options. The report format used can be direct output to a printer or generation of
an MS Word report. The desired report format can be selected from the Options menu, under IEC
Report Setup. A sample section of an IEC 61000-4-13 test report is shown below. MS Word
reports are automatically saved in the C:\Program Files\California Instruments\Cigui32\Reports or
C:\Program Files\California Instruments\CiguiSII\Reports directory.
