I need a help:
I have an SWR bridge - 2 X 1:40 transformers on a conventional circuit and
from this bridge I have two rectified voltages: forward and reflected.
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 ...
