Setting Up the Oscilloscope
To connect power
The oscilloscope power supply automatically adjusts for line input voltages in
the range 100 to 240 VAC. Therefore, you do not need to adjust an input line
voltage setting. The line cord provided is matched by Agilent Technologies to
the country of origin of the order.
