- | The waveform generator should be configured for a 1 KHz triangle wave with 3 volt amplitude and 1.5V offset. The input of scope channel 2 (2+) is used to measure the stabilized output current at the collector of Q2. | + | The waveform generator should be configured for a 1 KHz triangle wave with 3 volt amplitude |
