Introduction

The N2840/1/2/3A and N2853A high-impedance passive probes and accessories

are a great choice for high quality at a very reasonable price. With the exception of

the N2840A, the probes include probe ID capability that allows most

oscilloscopes, such as Keysight’s InfiniiVision and Infiniium series, to detect the

probe’s impedance and attenuation ratio.

Oscilloscope Compatibility

To be compatible with the probes, the oscilloscope must have a 1 MWinput

resistance shunted by 5 to 30 pF of input capacitance.

Handling the Probe

Handle the probe with care and refer to the safety notices in this manual. The

probe cable is a sensitive part of the probe, so use care not to damage the probe

through excessive bending or pulling. Avoid any mechanical shocks to the probe

to guarantee accurate performance and protection.

CAUTION

Before using the probe, refer to “Safety Information" on page 18.

CAUTION

Always wear an ESD wrist strap when working with the probe. Not

doing so can result in the probe becoming permanently damaged.

Introduction

N2840/1/2/3A and N2853A User’s Guide 5

Accessories

The probes come with the accessories shown in Figure 1. A probe tip is

pre-installed on the probe. N2840A probes do not include the BNC adapter.

Two additional accessories not supplied with the probes are available: the PCB

socket adapter and the dual-lead adapter. Refer to “Printed-Circuit Board

Adapter" on page 11 and to “Dual-Lead Adapter" on page 13.

Introduction

WARNING

Handle Probe Tips and Ground Spring Carefully. The probe tip and

ground spring are sharp. Handle these items with care to avoid

personal injury.

NOTE

To order a replacement kit that provides all of the supplied accessories

listed in Table 2, order accessory kit N2856A. The quantities of the

accessories included in the kit are the same quantities originally

supplied with the probe.

Introduction

N2840/1/2/3A and N2853A User’s Guide 7

Cleaning the Probe

Disconnect the probe from the oscilloscope and clean the probe with a soft cloth

dampened with a mild soap and water solution. Do not allow any solution to enter

the probe. Make sure that the probe is completely dry before reconnecting it to an

oscilloscope.

Inspecting the Probe

• Inspect the shipping container for damage.

Keep the damaged shipping container or cushioning material until the contents

of the shipment have been checked for completeness and the probe has been

checked mechanically and electrically.

• Check the accessories.

• If the contents are incomplete or damaged, notify your Keysight Technologies

Sales Office.

• Inspect the probe. If there is mechanical damage or defect, or if the probe does

not operate properly, notify your Keysight Technologies Sales Office.

If the shipping container is damaged, or the cushioning materials show signs of

stress, notify the carrier as well as your Keysight Technologies Sales Office. Keep

the shipping materials for the carrier’s inspection. The Keysight Technologies

office will arrange for repair or replacement at Keysight Technologies’ option

without waiting for claim settlement.

NOTE

When using any accessory, the probe assembly-accessory combination

is only rated for measurements on mains isolated circuits, not CAT II, III,

or IV circuits.

8 N2840/1/2/3A and N2853A User’s Guide

Using the Probe

This section describes how to attach the various accessories as well as the

channel ID tags. Before making measurements, compensate the probe as

explained in “Low-Frequency Compensation" on page 16.

Channel Identification Tags

When multiple probes are connected to the oscilloscope, it can be difficult to

determine which probe is connected to each oscilloscope channel. To quickly

identify a probe tip with the associated channel input, use the colored channel ID

tags. Snap one color-matched tag to each end of the probe’s cable as shown in

Figure 2. Select the tag color that matches the oscilloscope’s channel color.

Figure 2 Channel ID Tags Attached to the Probe Cable

WARNING

Must be Grounded. Before making connections to the input leads of

this probe, ensure that the probe’s output connector is attached to the

channel input of the oscilloscope and that the oscilloscope is properly

grounded.

WARNING

The maximum input voltage rating of the probe decreases as the

frequency of the applied signal increases. Refer to Figure 14 on

page 21.

CAUTION

To protect against electrical shock, use only the accessories supplied

with or available for this probe.

Using the Probe

N2840/1/2/3A and N2853A User’s Guide 9

Retractable Hook

Use the retractable hook tip to make quick connections for hands-free probing. To

attach the retractable hook tip to the probe, gently slip the tip onto the end of the

probe barrel. Once the tip is attached to the probe, push the tip’s collar towards

the probe body to expose the hook.

Figure 3 Push the Tip onto the Probe’s Barrel

Ground Spring

The ground spring improves measurement performance by providing a short

ground connection. The shorter lead reduces the inductance in the ground return

path which corresponds to higher performance than using the alligator ground

lead. To attach the ground spring, insert it over the end of the probe barrel as

shown in Figure 4. The spring must make contact with the metallic band on the

probe’s barrel.

Figure 4 Ground Spring Placed on Probe Tip

CAUTION

Avoid damaging the probe tip. Always align the axis of the retractable

hook tip with the probe tip when inserting the tip.

10 N2840/1/2/3A and N2853A User’s Guide

Using the Probe

Alligator Ground Lead

Use the alligator ground lead to reach circuit grounding points that are farther

away from the probing location than can be reached by the ground spring.

Because the longer lead increases the inductance in the ground return path, this

solution results in slightly lower performance than using the ground spring.

Figure 5 Probe with Alligator Ground Lead Attached

BNC Adapter

The BNC adapter connects the probe tip to a BNC (female) connector. Insert the

probe’s tip into the adapter as shown in Figure 6.

Figure 6 BNC Adapter

NOTE

The BNC adapter is not provided with N2840A probes but can be

ordered (part number 1250-3978).
