I have this circuit where I have to measure three things.
#1.Measure the dc output voltage with zero differential voltage.
#2.Measure the differential gain by using V1 and V2 as the inputs. Verify the differential gain at 1KHz.
#3.Measure the common mode gain with a 10 volt peak voltage at 1 KHz.
For #1 I don't really understand what the instructor means by zero differential voltage. What I get is that both V1 and V2 must be of same voltage and with that setup I should measure DC voltage at vout. Is this correct?
For #2 I would set V1 to 100mVpk and V2 to 50mVpk. Since the gain is set for 10 the output should be (V1-V2)*10. Is this also correct?
For #3 I would use only one input at 10Vpk and measure the gain?
