I need help understanding how to do 1.5 and 1.5. I need clarification, please show or explain steps. Thanks in advance!

1.5 Connect a DMM at the across the load resistance and configure it to measure DC Volts. Record the

reading and compare it to the DC value calculated in 1.4. Do the measured values agree with the

calculated values?

Explanation / Answer

We have to keep our DSS in DC mode and red color probe should be in contact with one end of the resistor and black color probe should be in contact with the other end. DC value calculated in 1.5 and 1.4 will be different, the impedance offered by the CRO and DSS are different( impedance offered by DSS > impedance given by CRO). So the DC value calculated by DSS will be higher and more precise. Measured value will be ofcourse less than the calculated value, because while calculating the value theoritically we will consider that output is offering infinite impedance. But in practical the impedance offered will be finite value and in the similar manner impedance offered by DSS will be 10M ohms. So because of this finite impedance, pottensial divider configuration is attained and the calculated value won't be coming at the output, instead we get a lower value because of pottensial division.
