  • Page 9 Laplace Instruments Ltd Synthesiser Manual . INTRODUCTION The RF6000 RF signal synthesiser is specifically designed to provide the signals required for testing RFI immunity of products to international standard IEC61000-4-3. IEC61000-4-3 IEC61000-4-3 immunity testing requires that the EUT (equipment under test) operates satisfactorily when subject to a strong electromagnetic field.
  • Page 10  Video interface running in separate window. Camera and camera hardware interface and software are supplied separately. The interface between the EUT and the RF6000 must be produced by the user to suit the requirements of the EUT. Cell characteristics The cell may be distinctly non linear in frequency characteristics.
  • Page 11 Synthesiser Manual Synthesiser Hardware Description The RF6000 acts as the ‘hub’ of the immunity test system. It generates the signal that is applied to the EUT, controls the field strength via a feedback signal from the cell, provides interfaces for the EUT and interfaces to the controlling PC via the serial port.

  • Page 13 4 identical channels are provided, each with BNC input and a range of 0- 10V dc. The input impedance is 100K. These are sampled by the RF6000 during each dwell period and results can be plotted on the screen as a test progresses.
  • Page 14 Connect the supplied 8 way cable from the cell to the feedback connector on the RF6000. Not required if not using a cell, but note that an alternative field sensor must be connected via the serial port on the rear panel..
  • Page 15 Laplace Instruments Ltd Synthesiser Manual 4.1.3 LETIS The LETIS (Laplace EMC Test Integration System) enables all the switching between power amplifiers to be done automatically. If using this unit, the interconnections are as shown below. Note that this diagram is for a complete system which includes the SA1002 or SA3000 analyser for emissions measurement.
  • Page 16 The RF6000 requires an analogue signal for field strength feedback. The range of the feedback signal is 0- 3v. The standard version of the RF6000 assumes a response time of approx 10ms to match the performance of the probe included with the LaplaCell. If an alternative probe is to be used, ensure the response time is similar or shorter than the 10ms quoted above.

  • Page 18 Laplace Instruments Ltd Synthesiser Manual This next screen allows you to select different locations for the software. It is recommended that the default be accepted Click Next Click ’Install’. A pop-up may appear which may request administrator rights. In this case the Admin password will be required.
  • Page 19 Laplace Instruments Ltd Synthesiser Manual The required USB driver is on the USB memory stick. Click on the …. DeVaSys_UsbI2cIo_Drivers_x64.msi Click ‘Next’. Read and accept, then click ‘Next’ Click ’Install’. A pop-up may appear which may request administrator rights. In this case the Admin password will be required.
  • Page 20 Laplace Instruments Ltd Synthesiser Manual Click ‘Install’ The installation is now complete. The hardware needs to be attached so that the driver can complete the setup before the RFSynth6 software will run properly. This only needs to be done once, thereafter the software will run without the software, but only for file view and printout purposes.
  • Page 21 Laplace Instruments Ltd Synthesiser Manual 5.2 Overview The screen layout The screen is divided into 7 main areas: The Main Menu bar across the top (File, Display, Configure, Help) in a conventional Windows application style. A full description of each menu item is given later.
  • Page 22 Laplace Instruments Ltd Synthesiser Manual Main Operating Modes The system has 3 quite separate modes of operation. The modes are: Standard mode. Conventional scans between a start and finish frequency at a fixed field strength level and programmable step size.
  • Page 23 Laplace Instruments Ltd Synthesiser Manual 5.3.2 EUT monitoring Prepare the EUT monitoring interface and connect to the RF6000. (See section 4.1.1) If using the cell camera and/or internal lighting, position these for optimum viewing. 5.3.2 System interfaces Check the Configure… System menu and ensure that the hardware USB links are listed in the table.
  • Page 24 Laplace Instruments Ltd Synthesiser Manual Check the cell door interlock. (Opening the door should cause door fault indicator to show and force power amplifier(s) to go into Standby mode) When all is ready to start the test, the test parameters can be entered in the Standard mode window.
  • Page 25 Laplace Instruments Ltd Synthesiser Manual 5.4.3 Running the scan. Once the scan is fully programmed, click on the ‘Report Results’ button in the test mode section to view the results of the test as the test proceeds. The target field strength profile will be displayed as a red line.
  • Page 26 Laplace Instruments Ltd Synthesiser Manual The system Status indicators will initially show ‘Settling’ as the system creates the required frequency and then ramps up the field strength to the desired value. A small dot on the results plot will show field increasing and settling at each step.
  • Page 27 Laplace Instruments Ltd Synthesiser Manual This Pre-Scan data can be saved for future use. Use File….Save Pre-Scan. When this PRE-SCAN is completed, the EUT can be placed in the cell. To then do a Pre-Scanned test, simply click on the Test button in the ‘Conventional’...
  • Page 28 Laplace Instruments Ltd Synthesiser Manual 5.5 Investigative Test - Single Point mode Select Single Point Single frequency mode enables the user to set a frequency and modulation mode and to manually control the field strength using simple UP and DOWN buttons. Frequency can also be adjusted in the same way.
  • Page 29 Laplace Instruments Ltd Synthesiser Manual 5.6 Custom Scan Mode In some cases it may be necessary to vary the field strength as the scan proceeds. Situations where this would be an advantage is if the EUT is intentionally sensitive at certain frequencies and should be be subjected to strong fields at these points.
  • Page 30 Laplace Instruments Ltd Synthesiser Manual The image below shows the results of the above custom scan settings. Note: The blue trace shows actual stress levels applied. The cursor can be used to read frequency and stress levels at each step.
