•

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.

Perform self-calibration first

For the oscilloscope to perform most accurately in the ambient temperature where it will be used, the self-calibration procedure described on page 4-25 should first be performed. Allow the unit to operate for at least 30 minutes before performing the self-calibration.

The Oscilloscope at a Glance

One of the first things you will want to do with your new oscilloscope is to become acquainted with its front panel. Therefore, we have written the exercises in this chapter to familiarize you with the controls you will use most often.

The front panel has knobs, grey keys, and white keys. The knobs are used most often and are similar to the knobs on other oscilloscopes. The grey keys bring up softkey menus on the display that allow you access to many of the oscilloscope features. The white keys are instant action keys and menus are not associated with them.

Throughout this book, the front-panel keys are denoted by a box around the name of the key, and softkeys are denoted by a change in the text type. For example, labeled Source under the trigger portion of the front panel, and

The Oscilloscope at a Glance

To connect a signal to the oscilloscope

The HP 54615B is a two-channel, 500 MHz bandwidth, 1 GSa/s sample rate oscilloscope with an external trigger input. The HP 54616Band HP 54616C are two-channel, 500 MHz bandwidth, 2 GSa/s sample rate oscilloscopes with an external trigger input. The input impedance of these oscilloscopes is

selectable – either 50Ω or 1 MΩ. The 50Ω mode matches 50Ω cables commonly used in making high frequency measurements. This impedance matching gives you the most accurate measurements since reflections are minimized along the signal path. The 1 MΩ mode is for use with probes and for general purpose measurements. The higher impedance minimizes the loading effect of the oscilloscope on the circuit under test. In this exercise you connect a signal to the channel 1 input.

To avoid damage to your new oscilloscope, make sure that the voltage level of the signal you are using is less than or equal to 250 V (dc plus the peak ac). For a complete list of the characteristics see chapter 5, "Performance Characteristics."

CAUTION

Do not exceed 5 Vrms in 50Ω mode. When input protection is enabled in 50Ω mode, the 50Ω load will disconnect if greater than 5 Vrms is detected. However the inputs could still be damaged, depending on the time constant of the signal.

The 50Ω input protection mode only functions when the oscilloscope is powered on.

•

Use a cable or a probe to connect a signal to channel 1.

•

The oscilloscope has automatic probe sensing . If you are using the probes supplied with the oscilloscope, or other probes with probe sensing, then the input impedance and probe attenuation factors will be automatically set up by the oscilloscope when automatic probe sensing is turned on. The default setting is to have automatic probe

sensing on. This is indicated by the selection of

To display a signal automatically

The oscilloscope has an Autoscale feature that automatically sets up the oscilloscope to best display the input signal. Using Autoscale requires signals with a frequency greater than or equal to 50 Hz and a duty cycle greater than

0.5%. When you press

channels that have signals applied, and selects a time base range based on the trigger source. The trigger source is selected from inputs that have a signal applied.

To set up the vertical window

The following exercise guides you through the vertical keys, knobs, and status line.

Center the signal on the display with the Position knob.

The Position knob moves the signal vertically, and it is calibrated. Notice that as you turn the Position knob, a voltage value is displayed for a short time indicating how far the ground reference is located from the center of the screen. Also notice that the ground symbol on the right side of the display moves in conjunction with the Position knob.

Measuremen t hi nts

If the channel is dc coupled, y ou can quickly measure the dc component of the signal by si m pl y noting its distance from the gr ound symbol.

If the channel is ac coupled, th e dc component of the s i gnal is removed allowing you to use gre ater sensitivit y t o di splay the ac component of the si gnal .

Turn the trigger Level knob and notice the changes it makes to the display.

As you turn the Level knob or press a trigger menu key, for a short time two things happen on the display. First, the trigger level is displayed in inverse video. If the trigger is dc coupled, it is displayed as a voltage. If the trigger is ac coupled or if LF reject was selected, it is displayed as a percentage of the trigger range. Second, if the trigger source is turned on, a line is displayed showing the location of the trigger level (as long as ac coupling or low frequency reject are not selected).

Adjust the Holdoff knob and observe how it changes the display.

Holdoff keeps the trigger from rearming for an amount of time that you set. Holdoff is often used to stabilize the display of complex waveforms. The Holdoff range is from 300.0 ns to about 13.5 s. When you adjust the Holdoff knob, the current holdoff time is briefly displayed in inverse video near the bottom of the display. For an example of using Holdoff, refer to the section, "To trigger on a complex waveform" on page 2-12.

To set a long ho ldoff time, go to a sl ower sweep speed. The value used to increment the holdoff depends upon the sweep s peed or

time/div sel ection. Howeve r, the actual holdoff v al ue is a fixed num ber; it is not a percentage of s w eep speed. For a time/div setting of 5 ns/div, the holdoff increment is 5 0 ns. For a time/div setting of 5 s/div, the holdoff increment is 100 ms.

Using Color (HP 54616C only)

With the HP 54616C color oscilloscope, you can select any of the seven available color palettes to assign colors to channels, cursors, stored waveforms, and text.

The seven color palettes allow additional customization, which allows you to easily distinguish between channel waveforms. In addition, when making measurements on a channel, wherever the channel number appears on screen, it is highlighted in the selected color.

The color palettes are individually named, and you can choose the palette that best suits your needs. You can change from the Default palette to any of the following:

•

Alternate 1 works well for people who are colorblind.

•

The colors in Alternate 2 are compatible with those used in HP 545xx-series oscilloscopes.

•

Alternate 3 sets the cursors to yellow.

•

Inverse 1 works well for hard copies.

•

Inverse 2 works well for overhead transparencies.

•

A Monochrome palette is also available.

In each palette, different colors are used for cursors, waveforms, softkeys, and Autostore. The background is always black, unless you select the Inverse palettes, which use a white background. Softkeys and the grid are always in white, except in the Inverse palettes, which set them to black.
