Hewlett-Packard to Agilent Technologies Transition

This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-

Packard’s former test and measurement, semiconductor products and chemical analysis

businesses are now part of Agilent Technologies. To reduce potential confusion, the only

change to product numbers and names has been in the company name prefix: where a

product name/number was HP XXXX the current name/number is now Agilent XXXX. For

example, model number HP8648 is now model number Agilent 8648.

Oscilloscopes

The HP 54720 is a modular, high-performance oscilloscope that

contains four data acquisition systems behind each of four plug-in

slots. Each plug-in slot provides 8 bits, 2-GSa/s maximum sample

rate, 16K maximum acquisition memory on the A models and 64K

maximum acquistion memory on the D models, and up to 1.5-GHz

bandwidth (depending on the plug-in you are using). A two-wide

plug-in, like the HP 54721A, uses two slots which allows a maximum

sample rate of 4 GSa/s and a maximum acquisition memory of 32K in

the A models and 128K in the D models. A four-wide plug-in, like the

HP 54722A, uses four slots which allows a maximum sample rate of 8

GSa/s and a maximum acquisition memory of 64K in the 54720A and

256K in the 54720D.

The HP 54720 also has firmware modularity by having a 3-1/2 inch

disk drive and flash ROMs, which allows for upgrades of the system

firmware features in the oscilloscope.

The plug-ins provide analog signal conditioning for the A/D converters

that are inside the mainframe.

This performance and flexibility provide you with the most accurate

analysis of single-shot phenomena found in any laboratory

oscilloscope.

The HP 54710 gives you the same performance as the HP 54720,

except that it has two acquisition systems.

This oscilloscope has many powerful features, and each of them is

described in this book. Your key to unlocking the power of the

oscilloscope depends how you combine its features for your

application, and your knowledge of how each feature effects the

operation of the oscilloscope.

All calibration and repair information is contained in the Service

Guide, and all programming information is contained in the

Programmer’s Reference.

Accessories Supplied

The following accessories are supplied with the oscilloscope.

•This User’s Reference

•One Programmer’s Reference

•One Service Guide

•One 2.3 meter (7.5 feet) power cord

Accessories Available

The following accessories are available for use with the oscilloscope.

CAUTION Make sure you use the correct length screw to rackmount the oscilloscope.

If you use a screw that is too short, it may not hold the oscilloscope safely in

the rack. If you use a screw that is too long, it can damage the oscilloscope.

In This Book

This book consists of 24 chapters, a glossary, and an index. Most of

the chapters describe the various menus in the oscilloscope. These

chapters contain the word "Menu" as part of their title. For example,

"Acquisition Menu" discusses the various softkey menus that come up

on the display when you press the Acquisition hardkey on the front

panel. The remaining chapters contain additional information about

the oscilloscope. For example, "Measurements" discusses how the

oscilloscope calculates the measurement results when you select an

automatic measurement.

You will find it easier to use this reference book if you are at least a

little familiar with how to use the front panel. The best way to learn

how to use the front panel is by reading the User’s Quick Start Guide

that is supplied with the oscilloscope.
