The document opens with a Graph display with a plot of “Vbase” (voltage to the base) in Volts
(V) versus Time (sec), and a plot of “Vcollector” (voltage to the collector) in Volts (V) versus
Time (sec), and the Signal Generator window which controls the Power Amplifier.
➤ NOTE: For quick reference, see the Experiment Notes window. To bring a display to the top,
click on its window or select the name of the display from the list at the end of the Display
menu. Change the Experiment Setup window by clicking on the “Zoom” box or the Restore
button in the upper right hand corner of that window.
➄
The “Sampling Options…” are: Periodic Samples = 200 Hz, Start condition is Analog Output =
0.01 V, and Stop condition is Samples = 200.
➅
The Signal Generator is set to output ±1.60 V, sine AC waveform, at 1 Hz.
➆ Arrange the Graph display and the Signal Generator window so you can see both of them.
• The plot of “Vbase” versus Time shows the output from the Power Amplifier (Analog Output).
The plot of “Vcollector” shows the voltage drop across the 330
Ω
resistor (Analog Channel A).
