ptc11 11-90 test setup : insertion loss measurement the insertion loss of a device connected into a given transmission system is defined as the ration of power (before and after insertion ) delivered to the output network beyond the point of insertion at a given frequency. fiq1 illustrate the test circuit configuration for making insertion loss measurement. to perform the insertion loss test , thru calibration must be done prior the measuring while the network analyzer being selected in s21 mode. a matching balun must be used to convert the 50ohms of output impedance of test instrument into the primary input impedance of the transformer under test. without this matching balun, impedance mismatch between the test instrument and the transformer causes measurement error. return loss measurement return loss measure the amount of energy that is lost due to reflection. reflected energy occur because of impedance mismatching these energy will reduce the overall system efficiency and emanate nuisance noise. fig2 illustrate the test configuration for making return loss measurement to perform the return loss test ,open , short,load calibration must be done prior to measuring while the network analyzer being selected in s11 mode. two matching baluns with appropriate output impedance must be used to match the impedance of the transformer under test as shown in the figure above cross talk measurement cross talk can be measured with setup shown in fig 3 by applying signal of identical information to the transmit channel and detecting the coupling signal level at receive channel. through calibration before measurement should be done both of transmit and receive channel should be terminated with proper load while measuring. ycl april .1999 r 0 data s heet s ubject t o c hange without notice sheet 4 of 5 b r s a network balun dut analyzer fig1 b a r s network analyzer balun dut b b s a network analyzer dut balun fig2 fig3 free datasheet http:///
