Dear Members, I have learned from members that ANSI C63.4 and CISPR 16-1-2 are the calibration standards for LISN for my daily measurement. I have one of my two LISNs ship out last week to an accredited calibration lab. I wonder if I need to ship out the other one for calibration since the second one is used for support equipment. Is it sufficient that I verify it in-house? If yes, I would need your help with calibration. I study A.8 of CISPR 16-1-2 Edition 1.2 and Annex E of ANSI C63.4-2003 this morning. Here are my questions: 1. The title of A.8 is "Measurement of the voltage division factor of an artificial mains V-network". What does "voltage division factor"? Does it mean insertion loss? 2. Is the adapter, mentioned in Figure A.6a, Figure A.6b of CISPR 16-1-2 and Figure E.1(a) of ANSI C63.4, commercially available? If not, is there any guidelines to make it (type of connectors, size and length of wires/cables, etc.)? Should I take a pin from a power plug and solder one end to a SMA receptacle? If yes, is there any preference for the type of the receptacle (cable jack, panel jack, bulkhead, etc. http://www.amphenolrf.com/Products/CatalogPages/sma_catalog.pdf)? 3. How do I terminate the mains port? The LISN, Solar 9252-50-R-24-N (same as 9252-50-R-24-BNC except with N connector) comes with a permanent attached power cord. Should I pick up a receptable (no wire attached) and connect 50 ohms resistor to L and N respectively, and connect the other end of the resistors to ground reference? 4. Is there any requirement (VSWR etc.) for the 50 ohms terminator? 5. Is 10 dB pads needed? Figure A.6a and Figure A.6b of CISPR 16-1-2 show them. The NOTE from Figure E.1(b) states "Attenuator pads not used with network analyzer. 6. Figure A.6a and Figure A.6b of CISPR 16-1-2 show two ports of network analyzer are used. Figure E.1(b) shows three ports of network analyzer are used. The vector network analyzer I have access to comes with four ports (http://www.home.agilent.com/agilent/pr duct.jspx?cc=US&lc=eng&pageMode=OV&pid=810708&ct=PRODUCT&id=810708). The calibration kit available is 3.5mm (htt ://www.home.agilent.com/agilent/product jspx?cc=US&lc=eng&pageMode=OV&pid=10000 3542%3Aepsg%3Apro&ct=PRODUCT&id=1000003542%3Aepsg%3Apro). How many ports do I need to connect to (port 1&2, or port 1&2&3)? I start using a VNA two weeks ago and is not familiar with it. As a matter of fact, I used a demo VNA (only two ports http://www.us.anritsu.com/pro ucts/37000D-Series_Lightning-Family-of- icroW-VNAs--Value-Line_ARSPG_ARQQSidZ643.aspx) to calibrate cable loss. Thank you for your time and look forward to hearing from you. Best regards, Grace -
