You measure a 5V digital signal with 100 ms (10%-90%) rise time.The pF capacitance in the probe/cable/scope combination influences the measuarement dramatically. True or False

You measure a 1 ns risetime digital signal. What frequency wil you use to check if the pF's in the probe/scope/cable combination are going to cause probe loading? Enter the answer in MHz without the unit.

You build a home made probe to counter probe loading. You use a 5K series resistor. What is the approximate scale factor (probe factor) you set on the oscilloscope?

You have made a home made probe to measure digital signals on an oscilloscope. The probe reduces probe loading. Which of the following is/are true. There can be more than one correct statement.Question 3Select one or more:1.You will not get reflections as long as you just use a 50 ohm co-ax cable.2.You use a coax as cable. This goes directly to the scope channel input through a 50 ohm termination.3.The probe factor (scaling) will change if you use a 50 ohm termination on the scope input.4.The coax cable must have a characteristic impedance of 50 ohm if a 50 ohm termination is used at the scope.5.You use a coax as cable. This goes directly to the scope channel input.

Name one factor for a successful incoming signal interpretation.
