I use Tektronix TDS3034B to measure the output of amplifier, which has a 6v dc voltage. so i use a 10uf capacitance to stop the dc voltage,but maybe dc voltage has a deep friendship with the ac voltage,it still goes through the capacitance as hard as possible. but in the simulation,it really stops the guy(dc v).i don't know what is the problem? is it the problem of my oscillograph?
