Oscilloscope Demonstrator Trainer.
Oscilloscope demonstrator trainer is
specifically designed for the study of working of an oscilloscope in an
open form. The controls are placed actually at the place as they are in
the layout schematic. Thus a trainee can easily locate any section,
& components in the section and study it thoroughly. The function
controls and the adjustment controls are fully accessible to the trainee
to verify their effect on the working of the scope. Creation of faults
and rectification of faults are important exercise covered in the
experiments. An illustrated block and circuit schematic and the
adjustment plan right in front of the trainee's eyes helps him
tocorrelate each operation during the demonstration.
Oscilloscope in open form with all components and controls placed on single PCB
Amplifier, Time base, Channel section signal available on test points
Separate sections for PS, EHT, VA, HA, TB & Trigger for easy identification
Fault creation & rectification provided
Track printing with different colours on different sections on component board for easy circuit training
Legend Printing on PCB for easy identification of components
Can be used as a standard 20 MHz Dual Trace Oscilloscope
