Electric OU: Supplement: Function Generators Connected in Series Act In Series
Yes, Virginia, they do. The Interstate F43 is set to make a square wave at a slow frequency. The WaveTek Model III is set to make a sine wave at a higher frequency and higher voltage. The two signals are shown separately on the HP180a oscilloscope, then the two function generators are placed in strict series and the scope is used to look at the total output signal. The signal from one function generator PASSES THROUGH the other function generator, only slightly attenuated by the second FG’s internal 50 ohm impedance, since the only load is the oscilloscope’s one megohm input impedance.
