Abstract The requirements of ISN for telecommunication port's conducted disturbance
testing according to GB 9254-2008 are introduced. The function and the characteristics
of ISN are analyzed. The longitudinal conversion loss (LCL) of ISN and its testing
principle are presented. Finally, the curves and data of telecommunication port's
disturbance voltage by using different ISNs to test the same product and different
kinds of product are discussed,which can be obtained the different LCL value of
different ISNa could cause the big difference of test results.
