Hi everyone,
I have a problematic issue which is about verification of an op-amp circuit output. In this circuit, The opamp output has a 0.7V dc offset and a 1.4V peak to peak AC component. So max-min values: 1.4-0V
the problem is that i am going to use that circuit to sample the grid voltage value so its accuracy is very important for me. To define the its accuracy i have to verify its output to input ratio (Gain).
As you know a big portion of oscilloscopes has a 8 bit resolution. So measuring an ac voltage with an 8 bit oscilloscope will not give me a right knowledge about is Gain and i can't use a high resolution multimeter to measure an AC signal.
Is there any simple way to measure the output with high accuracy by using an oscilloscope or another else?
Regards
