Measurement and Instrumentation The time/div and voltage axes of an oscilloscope have been creased. A student connects a 1 KHz, 5 V P-P square wave calibrition pulse to channel-1 of the scope and observes the screen to be as shown in the upper trace of figure. An unknown signal is connected to channel-2 (lower trace) of the scope. If the time/div and V/div on both channels are the same, the amplitude (P-P) and period of the unknown signal are respectively 10 V, 1 ms. 7.5 V, 2 ms. 5 V, 2 ms. 5 V, 1 ms. 10 V, 1 ms. 7.5 V, 2 ms. 5 V, 2 ms. 5 V, 1 ms.
