Chapter 2: Preparing for Use

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 to the input voltage and frequency). Line frequency must be in the range 47 to 440 Hz. Power consumption is 390W maximum.

Position the instrument where it will have sufficient clearance for airflow around the top, back, and sides.

15.9 mm both sides

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.

2–4

Chapter 2: Preparing for Use

To connect the mouse or other pointing device

• Plug the mouse into the matching connector on the back panel of the oscilloscope.

The mouse is included with the oscilloscope, but using it is optional. While you can operate many oscilloscope functions with only the front-panel keys and knobs, you will need the mouse to access advanced oscilloscope functions through the graphical interface, or to find out more about the oscilloscope through the built-in information system.

The optional touchpad pointing device connects in exactly the same way as the mouse.

The supplied mousepad provides the correct surface for smooth mouse operation. To modify the mouse configuration, see the User’s Quick Start Guide.

To attach the optional trackball

1 Push in the latch on the trackball baseplate to extend the metal tabs. Insert the lower

tab into the frontmost slot on the side of the oscilloscope. You can only install the trackball on the right side of the oscilloscope.

2–5

Chapter 2: Preparing for Use

To attach the optional trackball

While holding the latch in, slide the metal tabs up and to the rear of the oscilloscope

until they fully engage the slot.

3 Release the latch. The trackball baseplate should now be secure against the side of the

oscilloscope.

4 Snap the trackball assembly onto the pins of the baseplate. The trackball and buttons

should face up and toward the front of the oscilloscope.

5 Connect the 9-pin “D” connector on the trackball cable to the COM1 port on the back

panel. Tighten the retaining screws.

For information on changing the trackball settings, see the User’s Quick Start Guide.

2–6

Chapter 2: Preparing for Use

To connect the keyboard

• Plug the keyboard cable into the matching connector on the back panel of the oscilloscope.

The keyboard simplifies access to some oscilloscope functions, such as entering file names when you store waveforms and setups to the disk. If you need to free desk space, place the keyboard on top of the instrument. Do not stack other objects on the keyboard; this will cause self-test failures on power-on.

To connect to the LAN card

• Connect your LAN cable to one of the connectors on the LAN card. Make sure the connection is secure. Two connections are possible on the LAN card: the RJ-45 connection and a BNC connection. Units equipped with 10/100Base-T LAN cards have an RJ-45 connector only.

RJ-45 Connection

Each Infiniium Oscilloscope now ships with a LAN card installed. If you want a LAN connection, but have an older Infiniium Oscilloscope model that does not have a LAN card installed, contact your Agilent Technologies Sales and Service Office. An Agilent Technologies LAN Card Installation Kit with instructions is available from Agilent Technologies, and describes how to add a LAN card to your Infiniium Oscilloscope. After you have connected to the LAN card, you must set up the network as described in the User’s Quick Start Guide.
