8. splaces the load from the calibration plane and introduces error For SWR readings the error is mainly caused by loss in the cable more loss means greater the error Generally this condition isn t a problem because your radio and the analyzer both see the same reduction in SWR However if you re documenting antenna SWR for design purposes the analyzer should be connected directly to the feedpoint through a short pigtail to minimize error Calibration plane error has far more significance for measuring impedance because of phase rotation in the cable In fact impedance readings may swing dramatically depending on the cable s electrical length and the severity of the load s mismatch referenced to 50 Ohms For meaningful impedance data always connect the analyzer directly to the DUT using the shortest cable possible 5 2Reactance Sign Ambiguity Most handheld analyzers including the KVE analyzer lack the processing capability to directly calculate the reactance sign for complex impedance Z Rs tj 5 3 In Case Of Difficulty Note that the KVE analyzer has no user adjustable alignment controls Opening the analyzer case to perform unauthorized procedures could void your warranty If unit fails to operate properly please check the suggestions below before contacting dealer for service or replacement Analyzer won t turn on Battery may be fully discharged Plug in to charger confirm red charge light comes on and check unit again after a cou
