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.
