-The first waveform generator should be configured for a 200 Hz Triangle wave with 4 volts amplitude and 0 offset. The second generator should be configured also for a 200 Hz Triangle wave with 4 volts amplitude and 0 volts offset but with 180 degree phase. The resistor dividers will reduce the signal amplitude seen at the bases of Q<sub>1</sub>and Q<sub>2</sub>to slightly less than 200 mV. Channel one of the scope should be connected with 1+ to the output of the first generator, W1 and 1- connected to W2. Channel 2 should be connected to display 2+ and 2- and set to 1V per division.
