Inspecting the Package Contents
❏Inspect the shipping container for damage.
Keep a damaged shipping container or cushioning material until you have
inspected the contents of the shipment for completeness and have checked the
oscilloscope mechanically and electrically.
❏Verify that you received the following items in the oscilloscope packaging.
• Oscilloscope
• (2) N2862A 10:1 10 MΩpassive probes (60 MHz and 100 MHz models)
• (2) N2863A 10:1 10 MΩpassive probes (150 MHz and 200 MHz models)
• CD-ROM containing user documentation
See Figure 1-1. (See table 1-1 for the power cord.) If anything is missing, contact
your nearest Agilent Technologies Sales Office. If the shipment was damaged,
contact the carrier, then contact the nearest Agilent Technologies Sales Office.
❏Inspect the oscilloscope.
• If there is mechanical damage or a defect, or if the oscilloscope does not
operate properly or does not pass performance tests, notify your Agilent
Technologies Sales Office.
• If the shipping container is damaged, or the cushioning materials show signs
of stress, notify the carrier and your Agilent Technologies Sales Office. Keep
the shipping materials for the carrier’s inspection. The Agilent Technologies
Sales Office will arrange for repair or replacement at Agilent’s option without
waiting for claim settlement.

Performing a Functional Check
Perform this quick functional check to verify that your oscilloscope is operating
correctly. See Figure 1-2.
1Turn on the oscilloscope. Use only power cords designed for your
oscilloscope. Use a power source that delivers 100 to 240 VAC, 47 Hz to
440 Hz. Wait until the display shows that all self-tests passed. Push the
Save/Recall button, select Setups in the top menu box and push the Default
Setup menu box.

WARNING To avoid electric shock, be sure the oscilloscope is properly grounded.
2Input a waveform to a channel of the oscilloscope.
3Press the Autoscale button and observe the signal on the display.

CAUTION To avoid damage to the oscilloscope, make sure that the input voltage at the
BNC connector does not exceed the maximum voltage (300 Vrms maximum).

Compensating Probes
1-7
Compensating Probes
Perform this adjustment to match your probe to the input channel. This should
be done whenever you attach a probe for the first time to any input channel.
Low Frequency Compensation
1Set the Probe menu attenuation to 10X. Press the appropriate channel
button on the front panel (1or 2), then select the Probe menu item until
10X appears.
2Attach the probe tip to the probe compensation connector and the
ground lead to the probe compensator ground connector. If you use the
probe hook-tip, ensure a proper connection by firmly inserting the tip
onto the probe.
3Press the Autoscale front panel button.

Probe Compensation
4If the waveform does not appear like the Correctly Compensated
waveform shown in Figure 1-3, then use a nonmetallic tool to adjust the
low frequency compensation adjustment on the probe for the flattest
square wave possible.
High Frequency Compensation
1Using the BNC adapter, connect the probe to a square wave generator.

Front Panel and User Interface Descriptions
One of the first things you will want to do with your new oscilloscope is to
become acquainted with its front panel. The front panel has knobs and buttons.
The knobs are used most often and are similar to the knobs on other
oscilloscopes.

1-12
Automatically Displaying a Waveform
The oscilloscope has an Autoscale feature that automatically sets up the
oscilloscope to best display the input waveform. Using Autoscale requires
waveforms with a frequency greater than or equal to 50 Hz and a duty cycle
greater than 1%.
When you press the Autoscale button, the oscilloscope turns on and scales all
channels that have waveforms applied, and selects a time base range based on
the trigger source. The trigger source selected is the lowest numbered channel
that has a waveform applied. The 3000 Series Oscilloscopes are two channel
oscilloscopes with an external trigger input.

Getting Started
Cleaning the Oscilloscope
1-13
Cleaning the Oscilloscope
• Clean the oscilloscope with a soft cloth dampened with a mild soap and
water solution.
CAUTION Do not use too much liquid in cleaning the oscilloscope. Water can enter the
oscilloscope’s front panel, damaging sensitive electronic components.
