18 Keysight Infiniium 90000A Series Oscilloscopes User’s Guide
1 Setting Up the Oscilloscope
Connecting Power
• Connect the power cord to the rear of the oscilloscope, then to a suitable AC
voltage source.
Table 1 Power requirements
Power 100 - 240 VAC at 50/60 Hz
Input power not to exceed 800 Watts
Use Supplied Power Cord
Use only power cords designed for your oscilloscope. 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 power cord provided is matched to the country of origin of the order.
The Mains wiring and connectors must be compatible with the connector used in the
premise electrical system. Failure to ensure adequate earth grounding by not using
the correct components may cause product damage and serious injury.
This oscilloscope has autoranging line voltage input. Before switching on the
oscilloscope, be sure the supply voltage is within the specified range and voltage
fluctuations do not exceed 10% of the nominal supply voltage.
Properly Ground the Oscilloscope
To avoid electric shock, be sure the oscilloscope is properly grounded.
