This chapter of the Agilent Technologies Infiniium Oscilloscope Service Guide gives you general information about the instrument. The following topics are covered in this chapter.

• Instrument identification

• Options

• Accessories

• Specifications and characteristics

• Test equipment requirements

Instruments covered by this service guide

On the rear panel of the instrument is a serial number label and a VIN # label. The serial number is in the form of XX00000000 while the VIN # is in the form of VIN # 0XX. The serial number is composed of two parts: the first two letters and the first four numbers are the serial prefix, while the last four numbers are the suffix. The prefix is normally the same for all identical oscilloscopes and changes only when a change has been made to the oscilloscope. However, the suffix is sequentially assigned and is different for each oscilloscope. The contents of this manual applies to oscilloscopes with serial number prefixes listed on the title page.

An oscilloscope manufactured after the printing of this manual may have a newer serial number prefix. This newer serial prefix indicates that the oscilloscope may be different from those described in this manual. The manual for this oscilloscope will be revised as needed. If you have an oscilloscope with a newer serial prefix, please refer to the Agilent Technologies website and download a newer manual edition in Adobe Acrobat (pdf) format. The Agilent Technologies URL is: “www.agilent.com”. It will be necessary to search on a key word such as “Infiniium Service Guide”, and follow the links.

For additional information on configuration differences see the following sections in this service guide:

• “To configure the motherboard jumpers and setup the BIOS” in the Troubleshooting section 5 for information on determining:

		•which computer configuration is contained in your oscilloscope
		•setting up the BIOS correctly for that configuration
		•setting the motherboard jumpers if the PC motherboard is changed.
	• Replaceable Parts section 7.
		This section contains exploded views for the different motherboard configurations, cabling
		schemes, and outside hardware versions. The Replaceable Parts List also contains the
		assembly part numbers for the different oscilloscope configurations.

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 ±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.

1Position the instrument where it will have sufficient clearance for airflow around the top, back, and sides.

Minimum 0 mm		Minimum 38.1 mm

Minimum 15.9 mm (maintained by feet; however, do not place on soft surfaces that will impede airflow)

Airflow requirements

Agilent 54835A/45A/46A – 250

Minimum 15.9 mm both sides

2Connect 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.

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

1Push 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

2While holding the latch in, slide the metal tabs up and to the rear of the oscilloscope until they fully engage the slot.

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

4Snap the trackball assembly onto the pins of the baseplate. The trackball and buttons should face up and toward the front of the oscilloscope.

5Connect 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

BNC 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.
