Generator of rectangular oscillations


Components specification


Recessing drawing


Recessing drawing from the side of printed wiring


Utilization of connection

  • Testing of capacitors according to the acoustic signal

  • Testing of semiconductor diodes

  • Testing of transistors

  • Testing of resistors


Students activities- checking questions

  • Describe a function of the acoustic tester

  • Describe a sound when faulty diode is testing

  • Describe a sound when capacitor 330nF, 220μF is testing


Practical students activities

  • Draw a rectangular oscillations from the screen of oscilloscope to the prepared raster.

  • Determine an amplitude of oscillations, period T.

  • Calculate a frequency f

  • Draw a graph of oscillation dependence, generated by a tester on amount of testing resistance1K, 10K.
