On the other side, if I have any reactive component at load side, there will be difference between source signal phase and load signal phase. Using a DBM I'm able to convert this phase difference into voltage. The question is: how can I convert degrees in reactive component value? My phase measurement ranges from -180 to +180 degree on a linear basis, e.g the phase comparator delivers some mV proportional to degrees. Knowing this I'll be able to measure SWR, R and J at the same time. Thanks in advance for any help ... 73 Marcus PY3CRX/PY2PLL S. B. do Campo - GG66rf http://py.qsl.br Active from "DC" to 24GHz
