1 Introduction How to Use this Manual This manual describes the operation of the Agilent 14761A Harmonic/Flicker Test System (HFTS) software when used in conjunction with the Agilent 6800-Series AC Power Source/Analyzers. Its primary function is as a reference manual. If you have a question about a specific screen or how to perform a certain task, simply turn to the appropriate section of the manual.
1 - Introduction The Agilent 6800-Series AC Power Source/Analyzers The Agilent 6800-Series AC Power Source/Analyzers are specifically designed for testing products compliant to the IEC low-frequency emissions regulations for quasi-stationary current harmonics, fluctuating current harmonics, and voltage fluctuations and flicker.
Introduction - 1 EN 61000-3-2 and EN 60555 Part 2 Regulations EN 61000-3-2 and EN 60555 Part 2 regulate the magnitude of harmonic currents drawn by products from the ac line. For example, harmonic currents can occur as a result of high peak currents drawn by switch-mode power supplies.
1 - Introduction EN 61000-3-3 Regulation EN 61000-3-3 regulates the magnitude, rate, and time-duration of voltage fluctuations and flicker caused by products connected to the ac line. Voltage fluctuations are created by time-varying current drains working against branch circuit impedance that exists in all power distribution networks. Flicker occurs when an incandescent lamp changes in intensity due to the frequency and amplitude of voltage fluctuations in the same branch circuit.
2 Installation Install the Software NOTE: A README.TXT file is included on the installation disks. It contains product updates or corrections that are not documented in this manual. Use any text editor to read this file. The Agilent 14761A HFTS software (p/n 5063-2363) comes on two disks. When installed, it requires 5 Mbytes of hard disk space, 8 Mbytes of RAM, and 512 Kbytes of conventional memory. It also requires the correct interface card drivers to be installed on your PC.

3 - Setting Up the Test ñ Selecting New From Template opens a dialog box that lets you select a template file which contains previously-configured test setup information. This template information will be copied into your new data file. The template itself is not changed unless you make subsequent changes to your setup and save them into the template using “Save as Template.”. When you run the test, the test data will then be added to the information obtained from the template.
Setting Up the Test - 3 Create a Template Template files contain setup information for the test that you will be running. Using templates can save valuable time by eliminating the need to enter repetitive data each time you set up a test. Create a template by entering information into the Main and the Test Setup windows. Use the Tab key to move among the different fields. 1.

One error will terminate the test when this is selected: UNR - when the output becomes unregulated. ñ Select termination when the current limit is exceeded.
4 Running the Test Before actual test data can be acquired, the pre-test must be run. This is accomplished in the Pre-Test window. As its name implies, the Pre-Test window centralizes functions that, following test setup, need to be performed prior to running an actual test. This includes running preliminary tests to measure quantities that are subsequently used to set test limits for Class C and Class D devices. Once the pre-test data is available, the main test can be started.
4 - Running the Test 3. It is also possible to increase the duration of the pre-test. One purpose of running a longer pretest is to obtain more data over which the test results are averaged. Additional data more accurately characterizes the worst-case operation of the equipment under test (see “Pre-test Measurements” for more information). 4. Press the Run Pre-test button to run the pre-test.
Running the Test - 4 Pre-Test Power Statistics This screen provides additional information about the active input power of the device under test.
4 - Running the Test Pre-Test Source Harmonics This screen displays the pre-test voltage data for harmonics 1-40 on a worst-case basis. The Limit(%) column indicates the permissible limits for each harmonic expressed as percentages of the fundamental voltage. For 230 V/50 Hz power distribution systems, these are: - No limits for the 1st harmonic (the fundamental) - 0.9% of Vfundamental for 3rd harmonic - 0.4% of Vfundamental for 5th harmonic - 0.3% of Vfundamental for 7th harmonic - 0.
Running the Test - 4 To Run a Pre-test for Voltage Fluctuations Pre-Test Summary 1. Select the Pre-test menu tab on the bottom of the screen to access the Pre-test Summary window. You can also access the Pre-test window from the View/Pre-test menu. 2. If desired, change the time delay from when power is applied until the pre-test is run. The default pre-test time is 10 seconds. 3. It is also possible to increase the duration of the pre-test.
4 - Running the Test display. The tabular data displayed in this window provides a permanent record of the test conditions that existed at the time of the voltage fluctuations test. ñ The Measured Values area on the right side of the display provide a record of the test conditions at the time the voltage fluctuations pre-test was run. ñ The Output Impedance of the Harmonic/ Flicker Test System is automatically set to the requirements of IEC 1000-3-3 when testing for Voltage fluctuations.
Running the Test - 4 value of the waveform by a one-shot rms current value obtained from the waveform data record. The quality of this measurement is a function of the variability of the current waveform crest factor over the integration period used for the corresponding rms current measurement.
4 - Running the Test 3. Select Perform post processing automatically at end of test execution to process test data immediately after the completion of the test. Post processing is required to generate test reports and to generate data for the Statistics and Probability displays. Depending on the length of the test, the post processing of data may require considerable time. Alternatively, you can post process the test data at a later time by opening the test file and pressing the Run Post processing button.
Running the Test - 4 Manual On/Auto Off (see caution) The ON pushbutton is active, letting the operator manually turn the output of the Agilent 6800-Series AC Power Source/Analyzer on from the Test window.

B Glossary Quasi-stationary Harmonics Quasi-stationary or steady-state harmonic currents are produced by electronic equipment that generates non-varying levels of current distortion, where the amplitude of each harmonic remains constant over time. This equipment appears as an unchanging load on the ac mains. Examples include test and measurement instrumentation such as oscilloscopes and multimeters, electronic ballasts, and video display equipment.
B - Glossary Template Files Template files contain test-setup data that may be used in multiple tests. By eliminating a portion of the setup task, using template files can streamline the test process. Template information is included with the test data when the test is run. At the beginning of each test you can elect to use an existing template file when running your test, or you can create a new template for the test by entering new setup information in the Main and Test Setup screens.
Glossary - B Failures Failures are those conditions that will cause a test to fail the regulations. The number of failures are displayed in the status bar on the bottom of the screen. You can override the failure criteria by specifying an override percent in the Test Setup Advanced Options window. Test limits may be adjusted above or below the values specified by the regulation, but any adjustment above 100% will flag the test as invalid in the test report.
B - Glossary D(t) (Relative Voltage Change Characteristic) The change in rms voltage, relative to the nominal voltage, as a function of time and between periods when the voltage is in a steady-state condition for at least 1 second. D(t) must not be > 3% for more than 200 milliseconds continuously during a voltage change event. Dmax (Maximum Relative Voltage Change) The difference between maximum and minimum rms values of the voltage change characteristic relative to the nominal voltage. Dmax must be ≤ 4%.

Command Summary - C CALCulate:INTegral:TIME This command selects the Pst integration time for IEC Flicker measurements. The parameter may only assume values of 1, 5, 10, and 15 minutes in accordance with IEC 868. The command will be accepted and may be queried, but will have no meaningful function unless the ac source is placed in IEC mode using the SYSTem:CONFigure command.
C - Command Summary CALCulate:LIMit:UPPer This command sets various limits associated with rms voltage fluctuations testing for IEC 1000-3-3. as described in the following table. All five parameters are type NRf. The order in which the five parameters are entered must correspond to the order in the table. vss delta Sets the maximum peak-to-peak variation of relative voltage1 that defines “steady-state”. At *RST this value is set to 0.0032. Note that this number is not specified by IEC 1000-3-3.
Command Summary - C FORMat This command specifies the response data format for the following queries: MEASure:ARRay:CURRent:DC? MEASure:ARRay:VOLTage:DC? MEASure:ARRay:CURRent:HARMonic[:AMPLitude]? MEASure:ARRay:VOLTage:FLUCutations:ALL? MEASure:ARRay:VOLTage:FLUCutations:FLICker? MEASure:ARRay:VOLTage:FLUCutations:PST? When ASCii is selected, the response format for these queries is NR3 Numeric Response Data. This format is selected at *RST.
C - Command Summary FORMat:BORDer This command sets the byte order of IEEE floating point values returned within Arbitrary Block Response Data. When NORMal is selected, the first byte sent is the sign bit and seven most significant bits of the exponent, and the last byte sent is the least significant byte of the mantissa. This ordering is most useful for big-endian controllers such as those that use Motorola processors.
Command Summary - C MEASure:ARRay:CURRent:HARMonic? This query returns an array of current harmonic magnitudes. Operation of the query is modified by the SYSTem:CONF command (see summary table under SYSTem:CONFigure). The parameter specifies the number of harmonic arrays to be returned in response to the query. If SYSTem:CONFigure specifies NORMal operation, the parameter is ignored (ie it is forced to 1).
C - Command Summary MEASure:ARRay:VOLTage:FLUCtuations:ALL? This query measures voltage fluctuations in accordance with the IEC 868 standard. It is only available when IEC mode is selected with SYSTem:CONFigure. The parameter specifies the number of Pst integration periods during which data will be returned in response to the query. This query returns the data structures associated with both the MEAS:ARR:VOLT:FLUC:FLIC query and the MEAS:ARR:VOLT:FLUC:PST query.
Command Summary - C 0 ↓ 99 0 ↓ 99 Record Number Error Code P_0.
C - Command Summary MEASure:ARRay:VOLTage:FLUCtuations:FLICker? This query measures voltage fluctuations in accordance with the IEC 868 standard. It is only available when IEC mode is selected with SYSTem:CONFigure. The parameter specifies the number of Pst integration periods during which voltage fluctuation arrays will be returned in response to the query.
Command Summary - C MEASure:ARRay:VOLTage:FLUCtuations:PST? This query measures voltage fluctuations in accordance with the IEC 868 standard. It is only available when IEC mode is selected with SYSTem:CONFigure. The parameter specifies the number of Pst integration periods for which data will be returned in response to the query. This query returns 1 data structure per specified integration period for a total of structures.
C - Command Summary SENSe:CURRent:PREFerence This command sets the phase reference for current harmonic phase measurements. If VOLTage is selected, the reference is the fundamental component of the measured output voltage. If CURRent is selected, the reference is the fundamental component of the measured output current.
Command Summary - C SYSTem:CONFigure This command sets the overall operating mode for the Agilent 6800-Series AC Power Source/Analyzers. The choices are normal mode, which causes the product to operate as a standard ac source, or IEC mode, which modifies the basic behavior of the transient and measurement systems to facilitate IEC measurements. SYSTem:CONFigure has a variety of global consequences that are summarized below: NORMAL MODE IEC MODE Base Sampling Rate 39.920792 kHz 38.
D Class Determination The following flowcharts document the class determination used by the Agilent 14761A HFTS software. Class determination is a function of the Pre-test. The flowcharts illustrate ñ the class determination process according to the device class that was selected in the Standard Options window ñ how a test is flagged as non-compliant based on class selection ñ how the pre-test limits are calculated.
