To connect power
The instrument Power Factor Correction (PFC) circuitry in the oscilloscope’s power supply
operates over a line voltage in the range of 100 to 240 Vac
±10% (the power supply is autoranging
to the input voltage and frequency). Line frequency must be in the range 47 to 440 Hz. Power
consumption is 390W maximum.
1
Position the instrument where it will have sufficient clearance for airflow around the
top, back, and sides.
2 Connect the power cord to the rear of the oscilloscope, then to a suitable ac voltage
source.
The line cord provided is matched by Agilent Technologies to the country of origin of order.
Ensure that you have the correct line cord. See “Power Cables and Plug Configurations” in
chapter 7.
WARNING SHOCK HAZARD!
BEFORE YOU CONNECT THIS INSTRUMENT TO MAINS POWER OR LIVE MEASURING
CIRCUITS, you must provide a protective earth ground. Failure to provide a protective earth
ground could result in a shock hazard if there is a failure in this instrument or equipment
connected to it.
The mains plug must be inserted in a socket outlet provided with a protective earth contact.
Do not use an extension cord (power cable) without a protective conductor (grounding).
Grounding one conductor of a two-conductor outlet does not provide an instrument ground.
A Three-wire Power Cable is Provided
This instrument is provided with a three-wire power cable. When connected to an appropriate ac power
outlet, this cable grounds the instrument cabinet.
