TRANSMISSION LINEANALYSER
TLA10
TLA-10 Transmission Line Analyzer has been designed
to help educators visualize standing waves
on a CRO and work on real transmission lines unlike
most of the transmission line trainers currently
available for educational purposes which use
artificially simulated line modules with lumped
parameters. An exhaustive manual has been
provided with the system, which provides detailed
experimental procedure of the system.
Features:
* To study standing waves and observe maxima
and minima of a transmission line on a CRO.
* Uses actual coaxial lines rather than simulated
ones.
* Appreciate significance of impedance
matching.
* Measures VSWR, reflection coefficient,
characteristic impedance, velocity of
propagation, dielectric constant and signal
attenuation.
* Study Time Domain Reflectometry.
* Study location and nature of
discontinuities,open/short, mismatched
terminations, etc.
* Offers a complete view of the transmission line
in analog and digital domains, which is
essential for complete understanding of
transmission line behaviour.
