Thanks so much!!

There are two pictures captured from oscilloscope, the input and output of one is in phase and another is out of phase. So what do these two picture represent? Which one is for input gain and which is for differential gain?

the one with higher Vpp in ch2 used to calculate differential gain. higher Vpp due to 1 input only. the one with lower Vpp at ch2 used to calculate common mode gain. lower Vpp due to double input in Vin from function generator.
