The ETB-219 is a comprehensive trainer kit designed for the determination of phase difference and frequency between two electrical signals using a Cathode Ray Oscilloscope (CRO). It helps students learn the practical method of comparing waveforms and calculating relative phase angles and frequency using standard Lissajous figures and time base measurements. This model includes a dual signal generator capable of producing sinusoidal waveforms of known frequency and amplitude, allowing users to observe phase shift, frequency ratio, and waveform patterns. It is widely used in basic electronics and instrumentation labs to reinforce theoretical concepts through hands-on experimentation. Key Features:
