When measuring phase angle between two waves using a CRO, the time base generator is connected to
1). X plane
2). Y plane
3). Both X and Y plate
4). Neither X nor Y plates
Oscilloscope is used in the X-Y mode to determine the phase angle between two signals of the same frequency.
A time-base generator produces saw-tooth voltage.
Time – base generator is not connected to X – Y plate.
