Oscilloscopes

A General-Purpose Oscilloscope

The HP 54615B, HP 54616B, and HP 54616C oscilloscopes offer

exceptional waveform viewing and measurements in a small,

lightweight package. These dual channel, 500 MHz bandwidth

oscilloscopes are designed for use in labs where high speed analog and

digital circuits are being tested. These oscilloscopes give you:

•1 ns peak detect

•1 GSa/s sample rate (HP 54615B)

2 GSa/s sample rate (HP 54616B and HP 54616C)

•500 MHz bandwidth, and 1 ns/div Main and Delayed time bases

•Selectable input impedance

•Protection of the internal 50 ohm load

•Adjustable time nulling to remove the effects of cabling

•250 MHz single-shot bandwidth (HP 54615B)

500 MHz single-shot bandwidth (HP 54616B and HP 54616C)

•Color display (HP 54616C)

These oscilloscopes are very easy to use because of their familiar

controls and real time display. You can discard your viewing hood as

these oscilloscopes have none of the viewing problems that are

associated with analog oscilloscopes. A bright, crisp display is

obtained at all sweep speeds and delayed sweep magnifications.

Storage is as simple as pressing a button. View events ahead of the

trigger using negative time. Cursors and automatic measurements

greatly simplify your analysis tasks.

You can upgrade this oscilloscope for hardcopy or remote control with

the addition of an interface module. Unattended waveform

monitoring and additional waveform math, such as FFT, can be added

with the addition of one of the Measurement/Storage modules.

Bring your scope and PC together with BenchLink software.

BenchLink, which runs under Windows, allows easy transfer of scope

traces and waveform data to your PC for incorporation into

documents or storage.

In This Book

This is the User and Service Guide for

the HP 54615B, HP 54616B, and

HP 54616C Oscilloscopes. This guide

contains five chapters.

First Time Users Chapter 1 is a quick

start guide that gives you a brief

overview of the oscilloscope.

Advanced users Chapter 2 is a series

of exercises that guide you through the

operation of the oscilloscope.

TV/Video triggering Chapter 3 shows

how to use enhanced TV/Video triggering

if you have Option 005 installed in your

oscilloscope.

Service technicians Chapter 4

contains the service information for the

oscilloscope. There are procedures for

verifying performance, adjusting,

troubleshooting, and replacing

assemblies in the oscilloscope.

Reference information Chapter 5 lists

the characteristics of the oscilloscope.
