Time Domain Reflectometer - Lumped Load
The purpose of this applet is to demonstrate the waveform shown
by a time domain reflectometer with a lumped load made of series
and parallel circuits with a resistor, capacitor or inductor.
This applet demonstrates time domain reflectometry using
a lossless transmission line. The voltage V(t) in the diagram is
plotted. Set the load ZL using the parameters in the scroll
bars. A circuit box must be pressed after values
are entered.
The values are:
RL = load resistance
CL = load capacitance
LL = load inductance
Choose one of the circuit boxes for the load type you wish to plot. The
symbol '||' represents a parallel circuit whereas '+' represents a series
combination of the load elements. Try using the time constant displayed to
set appropriate scroll bar values. he LL and CL buttons will not work if
those values are set to zero. Note that all values are comprised of a
mantissa (0 to 9.99 range) multiplied by a power of ten exponent (-20 to 20
range).
Propagation time (Tp) represents the time required for
the energy to travel through the transmission line, to the load and back
again.
