To prepare your oscilloscope for use, you need to do the following tasks.

After you have completed them, you will be ready to use the oscilloscope. After you have done a few basic tasks, you will connect probes to the oscilloscope. The number of probes, and the type of probes that you will use depends on the oscilloscope model that you have.

Then release the pivots. Continue pivoting the handle until it clicks into a set position. The oscilloscope power supply automatically adjusts for input line voltages in the range to VAC.

Therefore, you do not need to adjust the input line voltage setting. The line cord provided is matched to the country of origin. Ensure that you have the correct line cord. See table Some front panel key lights will come on and the oscilloscope will be operational in about 5 seconds. The grid or graticule intensity on the display can be adjusted by pressing the Display key, then turn the Entry knob labeled on the front panel to adjust the Grid control.

Be sure to connect the probe ground lead to a ground point on the circuit. The probe ground lead is connected to the oscilloscope chassis and the ground wire in the power cord. If you need to connect the ground lead to a point in the circuit that cannot be grounded to power ground, consider using a differential probe. You should compensate you probes to match their characteristics to the oscilloscope.

A poorly compenstated probe can introduce measurement errors. To compensate a probe, follow these steps:. Turning off power to the circuit under test would only prevent damage that might occur if you accidentally short two lines together while connecting probes. You can leave the oscilloscope powered on because no voltage appears at the probes. The digital probe cable is indexed so you can connect it only one way. You do not need to power-off the oscilloscope. Use only the Agilent part number digital probe kit supplied with the mixed-signal oscilloscope.

Be sure to connect the ground lead. Other probe leads are omitted from the figure for clarity. The ground lead improves signal fidelity to the instrument, ensuring accurate measurements. Chapter 2 Front-panel Overview—A quick start guide to get you familiarize you with the front-panel operation.

To view Quick Help information: 1 Press and hold down the key for which you would like to view help. Page 36 1- Page 38 Front-Panel Overview Before you make measurements using the Agilent series Oscilloscopes, you must first set up the instrument using front-panel controls.

Then, make the measurement and read the display results. These oscilloscopes operate much like an analog scope, but it can do much more. When you press Run key is illuminated in green , the trigger processing and screen update rate are optimized over the memory depth.

Single acquisitions always use the maximum memory available—at least twice as much memory as acquisitions captured in Run mode—and the scope stores at least twice as many samples.

Page 40 Front-Panel Overview Important Oscilloscope Considerations Peak Detect acquire mode In Peak Detect acquisition mode, any noise, peak, or signal wider than 5 ns will be displayed, regardless of sweep speed. Page 41 Front-Panel Overview Important Oscilloscope Considerations Auto-Single mode In Normal trigger mode, the oscilloscope will not trigger or display a waveform unless a trigger signal is present and trigger conditions are met.

In this trigger mode, each time Single is pressed, the oscilloscope will wait for a valid trigger. In Auto or Auto Lvl trigger mode, the oscilloscope will generate a trigger for you if one is not found in the predetermined time from when the trigger system is armed. Page 42 Front-Panel Overview Important Oscilloscope Considerations Post Acquisition Processing In addition to changing display parameters after the acquisition, you can do all of the measurements and math functions after the acquisition.

Measurements and math functions will be recalculated as you pan and zoom and turn channels on and off. Page Front-Panel Operation Front-Panel Operation This chapter provides a brief overview of interpreting information on the display and an introduction to operating the front-panel controls. Detailed oscilloscope operating instructions are provided in later chapters.

Page Interpreting The Display Front-Panel Overview Interpreting the display Interpreting the display The oscilloscope display contains channel acquisitions, setup information, measurement results, and softkeys for setting up parameters. Digital Trigger point, Delay Sweep Trigger Trigger Trigger Analog channel time reference time speed mode type source channels activity Autoscale displays all connected signals that have activity.

To undo the effects of Autoscale, press the Undo Autoscale softkey before pressing any other key. The default configuration returns the oscilloscope to its default settings. This places the oscilloscope in a known operating condition. Page To Adjust Analog Channel Vertical Scaling And Position Front-Panel Overview To adjust analog channel vertical scaling and position To adjust analog channel vertical scaling and position This exercise guides you through the vertical keys, knobs, and status line.

The position knob moves the signal vertically; The digital channels are displayed when these keys are illuminated. You are viewing multiple acquisitions of the same signal similar to the way an analog oscilloscope displays waveforms. When Delayed mode is selected, the display divides in half and the delayed sweep icon displays in the middle of the line at the top of the display. The top half displays the main sweep and the bottom half displays the delayed sweep.

Page To Make Cursor Measurements Front-Panel Overview To make cursor measurements To make cursor measurements You can use the cursors to make custom voltage or time measurements on scope signals, and timing measurements on digital channels. Page To Make Automatic Measurements Front-Panel Overview To make automatic measurements To make automatic measurements You can use automatic measurements on any channel source or any running math function.

Cursors are turned on to focus on the most recently selected measurement right-most on the measurement line above the softkeys on the display. Page 62 Triggering the Oscilloscope The Agilent series Oscilloscopes provide a full set of features to help automate your measurement tasks, including MegaZoom technology to help you capture and examine the stored waveforms of interest, even untriggered waveforms.

The figure below shows the conceptual representation of acquisition memory. Think of the trigger event as dividing acquisition memory into a pre-trigger and post-trigger buffer. The position of the trigger event in acquisition memory is defined by the time reference point and the delay setting.

When the trigger event is found, the oscilloscope will fill the post-trigger buffer and display the acquisition memory.

Holdoff Holdoff sets the amount of time that the oscilloscope waits before re-arming the trigger circuitry. Page 68 Triggering the Oscilloscope To set holdoff Holdoff Operating Hints Holdoff keeps a trigger from occurring until after a certain amount of time has passed since the last trigger. This feature is valuable when a waveform crosses the trigger level multiple times during one period of the waveform. Without holdoff, the scope could trigger on each of the crossings, producing a confusing waveform.

Page Trigger Types Trigger Types The oscilloscope allows you to synchronize the display to the actions of the circuit under test by defining a trigger condition.

The triggering modes include Auto Level, Auto, and Normal. Triggering types include edge, pulse width, pattern, duration, sequence, I C, and TV trigger. Page To Use Edge Triggering Triggering the Oscilloscope To use edge triggering To use edge triggering The Edge trigger type identifies a trigger by looking for a specified slope and voltage level on a waveform.

You can define the trigger source and rising or falling edge in this menu. The trigger type, source, and level is displayed in the upper-right corner of the display. Page 71 Triggering the Oscilloscope To use edge triggering Analog source Press the analog channel source softkey to select an analog source. Adjust the trigger level for the selected analog channel by turning the Trigger Level knob. The position of the trigger level for the analog channel is indicated by the trigger level icon if the analog channel is on at the far left side of the display when DC coupling is selected.

Page To Use Pulse Width Triggering Triggering the Oscilloscope To use pulse width triggering To use pulse width triggering Pulse Width triggering sets the oscilloscope to trigger on a positive pulse or a negative pulse of a specified width. If you want to trigger on a specific timeout value, use Duration trigger in the trigger More menu. Page 73 Triggering the Oscilloscope To use pulse width triggering 3 Press the pulse polarity softkey to select positive or negative polarity for the pulse width you want to capture.

The selected pulse polarity is displayed in the upper-right corner of the display. A positive pulse is higher than the current trigger level or threshold and a negative pulse is lower than the current trigger level or threshold. The qualifiers can be set from 10 ns to 10 s. Page To Use Pattern Triggering Triggering the Oscilloscope To use pattern triggering To use pattern triggering The Pattern trigger identifies a trigger condition by looking for a specified pattern.

This pattern is a logical AND combination of the channels. Page 76 Triggering the Oscilloscope To use pattern triggering 3 For each channel you select, press one of the condition softkeys to set the condition for that channel in the pattern. A high is a voltage level that is greater than the channel's trigger level or threshold level. Page To Use Duration Triggering Triggering the Oscilloscope To use duration triggering To use duration triggering Duration trigger lets you define a pattern, then trigger on a specified time duration of this logical AND combination of the channels.

Page 78 Triggering the Oscilloscope To use duration triggering 3 For each channel you select, press the logic level softkey to set the condition for that channel in the pattern.
