How does the input impedance of a Cathode Ray Oscilloscope (CRO) primarily relate to its deflection sensitivity?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Lower input impedance leads to higher deflection sensitivity.
- 2It is directly proportional at low input impedance and inversely proportional at high input impedance.
- 3The input impedance of the CRO does not directly affect its internal deflection sensitivity, though high impedance prevents loading the circuit under test.✓
- 4Higher input impedance strictly leads to higher internal deflection sensitivity.
Correct answer
The input impedance of the CRO does not directly affect its internal deflection sensitivity, though high impedance prevents loading the circuit under test.
