' Set the vertical range to 8 volts.
myScope.WriteString ":CHANNEL1:RANGE 8"
' TIME_RANGE - Sets the full scale horizontal time in seconds. The
' range value is 10 times the time per division.
' Set the time range to 0.002 seconds.
myScope.WriteString ":TIM:RANG 2e-3"
' TIME_REFERENCE - Possible values are LEFT and CENTER.
' - LEFT sets the display reference on time division from the left.
' - CENTER sets the display reference to the center of the screen.
' Set reference to center.
myScope.WriteString ":TIMEBASE:REFERENCE CENTER"
