• GND: In ground mode, the input signal is replaced by ground, which causes the oscilloscope to draw a line on the screen at the ground level (0 Volts) This mode is used to check where ground is on the screen (There is also an arrow on the left side of the screen that marks the ground level )

Brief Note on triggering: As you hopefully know, an oscilloscope displays a measurement of Voltage vs Time (vertical and horizontal respectively) A trigger is comprised of a voltage (i e 3V, 5V, GND) and a direction (i e rising or falling) The scope waits for a trigger to occur before it refreshes the screen
The Oscilloscope and Phase Measurements
Select the mode of ternate" or "Chop " For frequencies less than 50 kHz, use "Chop " For frequencies greater than 50 kHz, use Alternate '4 Once the traces are on the screen, use the Gnd switch o set both pat- terns in the vertical center of the screen: Measure the number of honzontal divisions (in centimeters) required
