Measuring Two Signals
You are testing a piece of equipment and need to measure the gain of
its audio amplifier. You have an audio generator that can inject a test
signal at the amplifier input. Connect two oscilloscope channels to the
amplifier input and output as shown. Measure both signal levels and use
these measurements to calculate the gain.
