The output signal on this trainer kit was observed using only an Oscilloscope and a frequency counter. Two tasks in this learning media were completed by students, namely measuring the output frequency and observing the phase shift. The phase-shift RC circuit in the trainer kit used a single Op-Amp 741 while the Network model utilized an Inverting Amplifier to determine the gain which must be ≥ 29 times, therefore, Rfeedback ≥ 29 Rgain (Rfeedback = 30 kΩ and Rgain = 1 kΩ). Furthermore, the Resistor and Capacitor modules were provided separately to be connected to the trainer through jumper cables. The Oscillator is one of the essential subtopics to be examined thoroughly by electrical engineering students. This research develops a phase-shift RC Oscillator trainer kit that can be used to give undergraduate students an understanding of one of the materials related to analog circuit practicum.
