General Information

To inspect package contents

❏ Inspect the shipping container for damage.

If your shipping container appears to be damaged, keep the 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 and any optional accessories in

the oscilloscope packaging (see figure following).

• 54620-Series Oscilloscope (54621A, 21D, 22A, 22D, or 24A)

• 10074C 10:1 150 MHz passive probes with ID: (2) for 54621A, 21D, 22A, or 22D oscilloscopes (4) for 54624A oscilloscope

• 54620-68701 digital probe kit (for 54621D or 22D)

• Accessory pouch and front-panel cover (standard for 54622A, 22D, and 24A) (optional on 54621A and 21D; order N2726A)

• Power cord (see table 1-3)

• IntuiLink for 54600-series Oscilloscopes software and RS-232 cable (for

54622A, 22D, or 24A). IntuiLink is a Windows application that makes it very easy for you to

download images, waveform data, or oscilloscope setups from the oscilloscope to your pc using either Microsoft Word or Microsoft Excel. After installation of IntuiLink, a tool bar in these Microsoft applications will make connection and data transfer from the oscilloscope very simple.

IntuiLink software is available free on the web at: www.agilent.com/find/5462xsw RS-232 cable may be ordered separately, part number 34398A

If anything is missing, contact your nearest Agilent Sales Office. If the shipment was d amaged, contact th e carrier, then cont act the ne arest Agil ent Sale s Office.

General Information

• Agilent IntuiLink Data Capture (for 54622A, 22D, or 24A) IntuiLink Data Capture is a standalone program for downloading waveform

data from the oscilloscopes to your PC via GPIB or RS-232 interface. It provides the capability to transfer deep memory data out of the oscilloscope, allowing up to 4MB (scope channels) and 8MB (logic channels). The IntuiLink for 54600-Series limits the size of acquisition data available to a maximum of 2,000 points regardless of actual number of acquisition points on the screen. With the IntuiLink Data Capture, the amount of points transferred will be the actual number of acquisition points currently displayed or you may select the number of points to download. It provides the following functionality:

• Download waveform data and display the data as a simple chart

• Save the data as binary or text files

• Copy the chart and a selected portion of the data to the clipboard. The

maximum data saved to the clipboard is 50,000 point

• Load saved waveform data back into the application IntuiLink Data Capture software is available free on the web at:

www.agilent.com/find/5462xsw RS-232 cable may be ordered separately, part number 34398A

❏ Inspect the oscilloscope

• If there is mechanical damage or a defect, or if the oscilloscope does not operate properly or does not pass the performance tests listed in the Service Guide, notify your Agilent Sales Office.

• If the shipping container is damaged, or the cushioning materials show signs of stress, notify the carrier and your Agilent Sales Office. Keep the shipping materials for the carrier’s inspection. The Agilent Sales Office will arrange for repair or replacement at Agilent’s option, without waiting for claim settlement.

Preparing the Oscilloscope for Use

To prepare your oscilloscope for use, you need to do the following tasks. A ft er y ou ha ve co mp l et ed th em , y ou wi ll be re a dy to us e t he o sc il lo sc op e.

In the following topics you will:

• adjust the handle

• power-on the oscilloscope

• adjust the display intensity

• connect the oscilloscope probes

• connect the digital probes (with 54621D and 54622D)

• connect a printer

• connect a RS-232 cable

• verify basic oscilloscope operation

• get started using the oscilloscope interface

• learn how to use Quick Help

This chapter also tells you how to:

• clean the oscilloscope

Setting up 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.

• When using the Agilent 54621A and 54622A 2-channel Oscilloscopes, and the Agilent 54624A 4-channel Oscilloscope, you will connect and use analog probes to examine analog signals.

Analog channels

(2 or 4, depending

on the oscilloscope

model)

• When using the Agilent 54621D and 54622D Mixed-Signal Oscilloscopes, you will connect and use both analog and digital probes to examine analog and digital signals.

Then release the pivots. Continue pivoting the handle until it clicks into a set position.

Preparing the Oscilloscope for Use

To power-on the oscilloscope

1 Connect the power cord to the rear of the oscilloscope, then to a suitable

ac voltage source.

The oscilloscope power supply automatically adjusts for input line voltages in the range 100 to 240 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 1-3

2 Press the power switch.

Some front panel key lights will come on and the oscilloscope will be operational in about 5 seconds.

Preparing the Oscilloscope for Use

To adjust the display intensity

The Intensity control is at the lower left corner of the front panel.

• To decrease display intensity, rotate the Intensity control counterclockwise.

• To increase display intensity, rotate the Intensity control clockwise.

Dim Bright

Intensity control

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.

Preparing the Oscilloscope for Use

To connect the oscilloscope probes

1 Connect the Agilent 10074C 1.5-meter, 10:1 oscilloscope probe to the

analog channel 1 or 2 BNC connector input on the oscilloscope, or channel 1 through channel 4 on the 54624A.

Maximum input voltage for analog inputs:

CAT I 300 Vrms, 400 Vpk CAT II 100 Vrms, 400 Vpk with 10074C 10:1 probe: CAT I 500 Vpk, CAT II 400 Vpk

2 Connect the retractable hook tip on the probe tip to the circuit point of

interest. 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.

Perfectly compensated

Over compensated

Under compensated

To compensate your 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:

1 Connect the probe from channel 1 to the Probe Comp signal on the lower-

right corner of the front panel. 2Press 3 Use a nonmetallic tool to adjust the trimmer capacitor on the probe for

Preparing the Oscilloscope for Use

To use the digital probes (mixed-signal oscilloscope only)

1 If you feel it’s necessary, turn off the power supply to the circuit under

test.

Off

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.

2 Connect the digital probe cable to D15 - D0 connector on the front panel

of the mixed-signal oscilloscope. 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 54620-68701 digital probe kit supplied with the mixed-signal oscilloscope.
