4.3.2.1. Test Equipment :
a : HP 16047A Transformer Test Fixture
b : HP HP 4192A Analyzer or equivalent
CPF127F
4.3.2.2. Test Setup : is shown in below
4.3.2.3. Test Procedure :
a : Set the measurement Frequency of interest
b : Calibrating the HP4192A L.C.Z. impedance Analyzer via the short . open, load
c : Connecting the Analyzer to the Line side of splitter with the 600ohm load across
the POTS(ISDN) side, while NT load is terminated with ZADSL-I.
d : Measure the impedance value R +jX and calculate the Return loss expressed in
decibel from the equation Return loss = 20 log ZR + Z M / ZR – Z M dB
e : Change another frequency of interest, then repeat step b~e.
