Sinusoidal Input Set the waveform generator to a $1$kHz sinusoidal function. Now gently increase the amplitude of vs$($t$).$ You should see an inverted and amplified version of vs$($t$)$ displayed as output voltage vo$($t$).$ Adjust vs$($t$)$ to have a peak$-$to$-$peak voltage of $2$V $($from $1$V to $+1$V$).$ Set the vertical scales for Channel $1$ to $1$V$/$div and Channel $2$ to $5$V$/$div$.$ Is the amplifier working as expected? Is the gain correct? Is the output inverted with respect to the input? Comment.
