Amitec Transmission Line Trainer 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.
* 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 in TDR.
* Study Time Domain Reflectometry.
* Study location and nature ofdiscontinuities, 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 behavior.
