{253} How To Set DSO to Test Signal / DSO Oscilloscope Attenuation / Coupling Setting Urdu Hindi

in this video i demonstrated How To Set #DSO to Test Signal / DSO Oscilloscope Attenuation / #Coupling #Setting. the oscilloscope have 1x attenuation setting to apply test signal directly to the oscilloscope, but at 10x setting the probe attenuates the test signal by 10 times so the oscilloscope will receive a reduced amplitude level signal. i explained in urdu hindi language
coupling option is to connect test signal to the dso sampling circuit.
dc coupling. in this setting the test signal is passed through a dc filter and oscilloscope displays the signal directly as it is at test point after processing through its processing circuit
ac coupling. in this option the dc component in the test signal is blocked and just ac signal is allowed to pass to the processing circuit, because in this option the DSO uses a capacitive filter circuit,
ground coupling. in this option the dso sampling circuit is connected to the ground so that the oscilloscope will not display any signal and the display bar will set to its present position
