9. In the Measurements toolbar, configure Amplitude and High measurements under the Voltage category for both
channels 1 and 2. Once you have selected these items, they should remain visible at the bottom of the MSO
display until you deselect them.

10. Make note of the amplitudes for channels 1 and 2 as well as the highs for channels 1 and 2. Divide the amplitude
on channel 2 by the amplitude on channel 1.
a. Gain of Circuit—Channel 2/Channel 1 (measured):_______________________
Is this value close to the gain of 11 that you predicted earlier? Note that it is not exactly 11. This is because of
imperfections in the op-amp as well as the nonzero tolerances of the resistors.
11. Observe how the gain changes when you configure a square or triangle FGEN output instead. You can change
the output waveform type by pressing the icons at the bottom of the FGEN segment. The amplitudes and gains
should still be similar to what they were with the sine wave output.
