KL-900A:
Laboratorio comunicazioni di base
|
This KL-900A Basic Communication Trainer includes the basic modules
to experiment on ground-level topics of a telecommunication
course. The purpose of the modules is to enable the student to
acquire a clear experimental view of the basic concepts and a
familiarization with the operative aspects of the work in the
telecommunication laboratory.
a
This
trainer combined the basic modules with experimental circuits.
It can offer thebeginner complete courses of basic communication.
a
With the
equipped power supply and signal unit, students only have to add
theoscilloscope or Spectrum Analyzer, then they can complete
various experiments independently.
a
KL-900A is
a open-modulized design, it enables can be extended experimental
range.
