Hi all,

For my project, I want to perform Distance to fault measurement in the
cable connecting the antenna. The principle is that a signal should be
sent to the cable and using the forward and reflected voltage VSWR
should be calculated and should be viewed in a spectrum analyzer. My
question is

1. *What transducer is used to detect the transmitted/reflected signals
from the cable?

2. Should the transducer be connected in series or parallel?

Anyone, Please help

look up time domain reflectometers... they are much simpler than what
you are thinking of. using a simple step input wave you measure the
time to the reflection. if you get fancy you can measure the polarity
and size of the reflection to determine if it is a short or open or
impedance change... if you really get fancy you can hook a scope up
and look at more details. the only transducer needed is a voltage
probe OR a current shunt, either one will work depending on the
installation needs.
