The 1130/1/2/4B InfiniiMax active probes are designed for probing differential and single-ended high-frequency signals. The probes are compatible with the Infiniium AutoProbe Interface which completely configures the Infiniium series of oscilloscopes for the probes.

Before using the probe, refer to “Safety Information" on page 31.

Before using the probes, refer to “Probe Handling" on page 12.

1 Getting Started

Introduction

Before you can use the probe, you must connect one of the available probe heads to an 1130/1/2/4B probe amplifier.

Figure 1 Probe Amplifier with Attached Head

Probe Heads

The available probe heads are shown in Figure 2 on page 9 and are documented in

Chapter 2, “Using Probe Heads". The InfiniiMax I probe heads are designed

specifically for the 1130/1/2/4B probes amplifiers. The InfiniiMax II probe heads are designed for 1168/9B probe amplifiers, but can also be used with the 1130/1/2/4B probe amplifiers.

The probe heads can be ordered at the same time as 1130/1/2/4B probe amplifiers. The E2669B and E2668B connectivity kits, described on page 21 and

page 20 conveniently package multiple probe heads and their accessories.

Differential probe heads offer easy measurement of differential signals and greatly improve the measurement of single-ended signals. Single-ended probe heads offer extremely small size for probing single-ended signals in confined spaces.

Compatible Oscilloscopes

Table 1 on page 10 lists the oscilloscopes that are compatible with the

1130/1/2/4B probes. Is Your Oscilloscope Software Up-to-Date? Keysight periodically releases Oscilloscope software updates to support your probe, fix known defects, and incorporate product enhancements.

Channel Identification Rings

When multiple probes are connected to the oscilloscope, use the channel identification rings to associate the channel inputs with each probe. Place one colored ring near the probe’s channel connector and place an identical color ring near the probe head.

Inspecting the Probe

Figure 3 on page 11 shows the accessories that are shipped with the 1130/1/2/4B

probe amplifiers. The probe amplifiers do not come with a probe head unless selected at the time of order. Any head shown in Figure 2 on page 9 can be ordered at any time for any 1130/1/2/4B probes.

• 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.

10 1130B-Series Probes User’s Guide

Getting Started 1

• 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 or pass calibration tests, 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.

Figure 3 Accessories Supplied With the Probe Amplifier

Cleaning the probe

If the probe requires cleaning, disconnect it from the oscilloscope and clean it with a soft cloth dampened with a mild soap and water solution. Make sure the probe is completely dry before reconnecting it to the oscilloscope.

1130B-Series Probes User’s Guide 11

1 Getting Started

CAUTION

Probe Handling

This probe has been designed to withstand a moderate amount of physical and electrical stress. However, with an active probe, the technologies necessary to achieve high performance do not allow the probe to be unbreakable. Treat the probe with care. It can be damaged if excessive force is applied to the probe tip. This damage is considered to be abuse and will void the warranty when verified by Keysight Technologies service professionals.

• Exercise care to prevent the probe end from receiving mechanical shock.

• Store the probe in a shock-resistant case such as the foam-lined shipping case

which came with the probe.

Connecting and Disconnecting Probe Heads

When disconnecting a probe head from an amplifier, pull the probe head connectors straight out of the sockets as shown in Figure 4. When connecting a probe head to an amplifier, push straight in. Always grasp the indentations located on the sides of the amplifier as shown in Figure 4. There are also indentations on many of the probe head sockets so you have a convenient place to grasp there as well.

Figure 4 Properly Pulling the Probe Head Straight Out

Avoid damaging the connection pins. Never bend the probe head in order to “pop” it loose from the amplifier. Do not wiggle the probe head up and down or twist it to remove the connectors from the sockets.

CAUTION

Handling the Probe Cable

Getting Started 1

Avoid degrading the probe’s performance. Do not twist, kink, or tightly bend the probe’s cable.

When the probe is attached to an oscilloscope, avoid letting object hit the probe cable where the cable exits the probe amplifier and bend it well beyond its limit.

When storing the probe, coil the cable in a large loops and avoid twisting the cable. Coil the cable in a similar manner to how garden hoses or extension cords are typically coiled. You can start by wrapping the cable around your thumb as shown in Figure 6. Then continue to circle your thumb, but provide a slight twist with each rotation. This allows the cable rotations to lie flat against each other and will eliminate the net twisting of the cable in the end.

Figure 6 Recommended Coil for Storage

1130B-Series Probes User’s Guide 13

1 Getting Started

CAUTION

Connecting the Probe to an Oscilloscope

Handling the Probe Amplifier

Make the coil’s radius fairly large so it does not induce kinking or bending.

The probes are only meant to be plugged into gold plated BNCs (like those on Infiniium oscilloscopes). To connect the probe to the oscilloscope, simply push the probe into the BNC connector and the locking mechanism automatically engages. To disconnect the probe, push and hold the locking lever to the left and then remove the probe.

The probe amplifier contains a delicate circuit board. Treat it carefully and take standard precautions (for example, not dropping it repeatedly or from large heights, not getting it wet, not smashing it with heavy objects, etc.). These probes are sensitive ESD devices so standard precautions need to be used to not ruin the probe from the build-up of static charges.

Securing Probe Heads and Amplifiers to Your DUTs

When soldering a probe head to a circuit, first provide strain relief by using low temperature hot glue (use as little as possible) or non-conductive double-sided tape. Do not use super glue and do not get the low temperature hot glue on the actual probe head tip as this can damage the precision components of your probing system (only use the low temperature hot glue on the probe head cables). The provided velcro pads can be used to secure your probe amplifier casing to the board.

Once strain relief has been provided, solder the probe tip to the circuit board and then plug the probe head into the probe amplifier.

Using Offset With InfiniiMax Active Probes

It is important to understand how the 113xA probes behave with respect to offset when different probe head / signal combinations are used.

The purpose of offset in active probes or oscilloscope front ends is to allow the subtraction of most or all of the dc component of the input signal so the signal can better utilize the dynamic range of the input. When using an InfiniiMax probe with an Infiniium oscilloscope, you can select the case (see the three cases described below) that applies for your measurement by selecting the Probes button under the channel setup menu. This allows you to select which type of probe head is being used and, if it is a differential probe head, allows you to select whether you are probing a differential or single-ended signal. With these inputs, the oscilloscope will use the proper type of offset for your measurement case. The specifics for each case are discussed below.

As an important side note, whenever adjusting the offset for a particular probe head, make sure to have a triggered signal.

Case 1. A single-ended probe head probing a single-ended signal

For this case, the offset control on the oscilloscope controls the probe offset and the channel offset is set to zero. This allows the offset voltage to be subtracted from the input signal before the signal gets to the differential amplifier. Since this subtraction is done before any active circuits, the offset range is large (±12V for the 113X amplifiers and 25-kW probe heads). Note that the minus probe tip is not present when using a single-ended probe head which means nothing is plugged into the "–" input of the probe amp. This is normal and causes no problems.

Case 2. A differential probe head probing a single-ended signal

For this case, the offset control on the oscilloscope controls the probe offset and the channel offset is set to zero. This allows the offset voltage to be subtracted from the input signal before the signal gets to the differential amplifier. Since this subtraction is done before any active circuits, the offset range is large (±12V for the 113X amplifiers and 25-kW probe heads). A differential probe can make higher bandwidth and more accurate measurements on single-ended signals than a single-ended probe and this method of applying offset to only the plus side of a differential probe means there is no sacrificing of offset range.

Case 3. A differential probe head probing a differential signal

For this case, the offset control on the oscilloscope controls the oscilloscope channel offset. The probe offset is not used and set to zero. Since the plus and minus sides of differential signals have the same dc component, it will be subtracted out and the output of the probe will by definition be centered around ground.

16 1130B-Series Probes User’s Guide

Getting Started 1

The channel offset allows the waveform seen on screen to be moved as desired. The allowable dc component in the plus and minus signals is determined by the common mode range of the probe which for the 113x probe amps and 25 kW probe heads is ±6.75 V.

Slew Rate Requirements for Different Technologies

The following table shows the slew rates for several different technologies. The maximum allowed input slew rate is 18 V/ns for single-ended signals and 30 V/ns for differential signals. Table 2 shows that the maximum required slew rate for the different technologies is much less that of the probe.

N5450B Extreme Temp Cable Extension Kit

CAUTION

The extreme temperature cable extension kit is an accessory that allows an oscilloscope probe to be used to monitor a device in a temperature chamber. Keysight’s Infiniimax probe amplifiers have a specified operating temperature range from 5 can be operated over a much larger range of temperatures. Use the extension cables to physically separate the amplifier from the probe head which allows you to operate the probe head inside a temperature chamber while the probe amplifier remains outside the chamber.

To ensure a high-quality measurement, the N5450B cable set have been phase-matched at the factory. A coupling tag is included with the cables to ensure the cables stay as a matched pair. To install the coupling tag, slip the small end of each cable through the holes in the tag. The tag can be positioned anywhere along the length of the cable and can withstand the temperature ranges specified.

Avoid rapid changes in temperature that can lead to moisture accumulating in the form of condensation on the probe components, as well as the DUT. If this occurs, wait until the moisture has evaporated before making any measurements.

Additional care must be taken when handling probe heads used during extreme temperature cycling because this process makes the probe heads less robust.

NOTE

N2880A InfiniiMax In-Line Attenuator Kit

Prevent abrasion and tears in the cable’s jacket, do not rest the extension cables on any metal objects or objects with sharp edges.

Do not kink the cables. The cables are designed to be flexible, but are not designed to be bent sharply.

Keep your extreme temperature testing probes separate from the probes they use under milder conditions. This is because cycling probe heads through extreme temperature ranges has a marked affect on their lifetimes as listed in Table 5. Only the lifetime of the probe head is affected by temperature cycling. The extension cables and probe amplifier should not need to be replaced with extended temperature cycling.

Discoloration or texture changes are possible with the extension cables. These changes do not, however, affect the performance or the quality of a measurement.

The in-line attenuators are an accessory for probes. The maximum input range of the 1130B probes are 5 V design allows you to add the N2880A InfiniiMax in-line attenuators between the probe head and probe amplifier to increase the maximum input range (as listed in

Table 6 on page 25). Additionally, these attenuators enable you to increase the

offset range of the probe as specified in Table 6 on page 25. When using the N2880A In-Line Attenuators, the bandwidth and rise time of your probing system is not affected. There is, however, a trade-off in noise (refer to Table 6) and in the accuracy of DC offset relative to the input.

The N2880A provides a pair of 6 dB, 12 dB, and 20 dB attenuators. The attenuators come as matched pairs and should only be used with each other. Each attenuator has a serial number. The pair of matching attenuators in each set will have the same four digit numeric prefix and will differ by the last letter (one attenuator in the matched pair will be labeled A and the other will be labeled B).

Compatibility with probe heads and amplifiers

NOTE

All InfiniiMax I probe heads and amplifiers are compatible with the N2880A In-line attenuators. However, the following two limitations should be considered when planning to use N2880A attenuators.

• The maximum input voltage of the InfiniiMax probe heads is ±30 Vdc (depending on the frequencies of your signal, the maximum allowed slew rate (see table below) may require that the maximum input voltage magnitude be less than 30V), so they should not be used to measure signals that exceed this range. This places a practical limit of 20 dB on the attenuators used with the InfiniiMax probing system. Larger attenuation ratios will only degrade the noise performance and gain of the system.

• Due to the N5380B dual-SMA probe head’s maximum input voltage specification of 2.28 V large enough to require an added attenuator.

Calibrating and Configuring Attenuators on an Infiniium Series Oscilloscope

The software in the Infiniium and InfiniiVision oscilloscopes will detect a probe when it is connected and by default will assume that no additional attenuators are installed. If you want to scale readings and settings on the oscilloscope so they are correct with the attenuators installed, refer to the procedures below for your specific oscilloscope series.

Configuring Attenuators on a Infiniium Scope

1130B-Series Probes User’s Guide 25

1 Getting Started

You cannot calibrate your InfiniiMax probes with the attenuators attached. Calibrate the InfiniiMax probes as you normally would (with no attenuators), configure the attenuators as discussed in the next section, and begin probing.

First, plug your InfiniiMax probe amplifier / probe head into one of the oscilloscope channels with the attenuators connected. Then enter the Probe Setup dialog box (can be reached via Setup > Probes on the oscilloscope menu). Press the Configure Probing System button. A pop-up window will appear where you can select External Scaling. Click the Decibel radio button under the External Scaling section and then set the Gain field to either –6 dB, –12 dB, or –20 dB depending on the attenuator you are using (be sure to include the negative sign). Finally, you will need to manually set the Offset field in this dialog box to zero out the signal.

Calibrating Probe with Attenuators on a InfiniiVision Scope

The following instructions only apply if you have InfiniiVision software release 5.25 or newer installed on your oscilloscope.

1 Plug your InfiniiMax probe amplifier / probe head into one of the oscilloscope

channels with the attenuators attached.

2 Press the Channel on/off key to turn the channel on (if the channel is off).

3 Press the Probe softkey in the Channel menu. A series of probe related softkeys

will appear.

4 Repeatedly press the second softkey from the left softkey until the probe head

selection matches the attenuator you are using. The choices are:

• 10:1 single-ended browser

• 10:1 differential browser

• 10:1 (+6 dB Atten) single-ended browser

• 10:1 (+6 dB Atten) differential browser

• 10:1 (+12 dB Atten) single-ended browser

• 10:1 (+12 dB Atten) differential browser

• 10:1 (+20 dB Atten) single-ended browser

• 10:1 (+20 dB Atten) differential browser

Once the probe head configuration has been selected, you can press the Calibration key in the same probe menu and follow the on-screen instructions to calibrate the probe/attenuator setup.

Frequency Response Plots

Figure 14 on page 27 shows the frequency response plots for four setups: the

probe without any attenuators, the probe with the 6 dB attenuators, the probe with the 12 dB attenuators, and the probe with the 20 dB attenuators.

N2881A InfiniiMax DC Blocking Caps

The DC blocking capacitors are an accessory for the probes. The architecture of the InfiniiMax probing system allows you to place the N2881A DC Blocking Caps in between the probe amplifier and the probe head (as shown in the picture below). These N2881A InfiniiMax DC Blocking Caps block out the DC component of the input signal (up to 30 Vdc). The N2881A InfiniiMax DC Blocking Caps can be used with the N2880A In-Line Attenuators. The order of the two products in the probing system (i.e. which one is closest to the probe amplifier) does not matter.

WARNING

CAUTION

WARNING

Do not install substitute parts or perform any unauthorized modification to the probe.

Do not operate the probe or oscilloscope in the presence of flammable gasses or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.

If the probe is used in a manner not specified by the manufacturer, the protection provided by the probe assembly may be impaired.

Do not attempt internal service or adjustment. Service should be carried out by a Keysight Technologies authorized service personnel. For any service needs, contact Keysight Technologies.

The probe cable is a sensitive part of the probe and, therefore, you should be careful not to damage it through excessive bending or pulling. Avoid any mechanical shocks to this product in order to guarantee accurate performance and protection.

Concerning the Oscilloscope or Voltage Measuring Instrument to Which the Probe is Connected

Whenever it is likely that the ground protection is impaired, you must make the instrument inoperative and secure it against any unintended operation.

If you energize the instrument by an auto transformer (for voltage reduction or mains isolation), the ground pin of the input connector terminal must be connected to the earth terminal of the power source.

Before turning on the instrument, you must connect the protective earth terminal of the instrument to the protective conductor of the (mains) power cord. The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. You must not negate the protective action by using an extension cord (power cable) without a protective conductor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection.

Capacitors inside the instrument may retain a charge even if the instrument is disconnected from its source of supply.

Troubleshooting

The following symptoms may indicate a problem with the probe or the way it is used. The probe is a high frequency device with many critical relationships between parts. For example, the frequency response of the amplifier on the hybrid is trimmed to match the output coaxial cable. As a result, to return the probe to optimum performance requires factory repair. If the probe is under warranty, normal warranty services apply.

Probe Calibration Fails

Probe calibration failure with an oscilloscope is usually caused by improper setup. If the calibration will not pass, check the following:

• Check that the probe passes a waveform with the correct amplitude.

• If the probe is powered by the oscilloscope, check that the offset is

approximately correct. The probe calibration cannot correct major failures.

• Be sure the oscilloscope passes calibration without the probe.

Getting Started 1

Incorrect Pulse Response (flatness)

If the probe's pulse response shows a top that is not flat, check for the following:

• Output of probe must be terminated into a proper 50W termination. If you are

using the probe with an Infiniium oscilloscope, this should not be a problem. If you are using the probe with other test gear, ensure the probe is terminated into a low reflectivity 50W load (~ ±2%).

• If the coax or coaxes of the probe head in use has excessive damage, then

reflections may be seen within ~ 1 ns of the input edge. If you suspect a probe head, swap it with another probe head and see if the non-flatness problem is fixed.

• If the one of the components in the tip have been damaged there may be a

frequency gain non-flatness at around 40 MHz. If you suspect a probe head, swap it with another probe head and see if the non-flatness problem is fixed.

Incorrect Input Resistance

The input resistance is determined by the probe head in use. If the probe head is defective, damaged, or has been exposed to excessive voltage, the input resistor may be damaged. If this is the case, the probe head is no longer useful. A new probe head will need to be obtained either through purchase or warranty return.

NOTE

Incorrect Offset

Returning the Probe for Service

Assuming the probe head in use is properly functioning, incorrect offset may be caused by defect or damage to the probe amplifier or by lack of probe calibration with the oscilloscope.

If the probe is found to be defective we recommend sending it to an authorized service center for all repair and calibration needs. Perform the following steps before shipping the probe back to Keysight Technologies for service.

1 Contact your nearest Keysight sales office for information on obtaining an RMA

number and return address.

2 Write the following information on a tag and attach it to the malfunctioning

equipment.

• Name and address of owner

• Product model number (for example, 1130B)

• Product Serial Number (for example, MYXXXXXXXX)

• Description of failure or service required

Include probing and browsing heads if you feel the probe is not meeting performance specifications or a yearly calibration is requested.

3 Protect the probe by wrapping in plastic or heavy paper.

4 Pack the probe in the original carrying case or if not available use bubble wrap

or packing peanuts.

1. MX0100A InfiniiMax Micro Probe Head

The MX0100A is a small, flexible, and lightweight solder-in probe head that allows you to conveniently probe denser and smaller-sized target devices. The micro size and flexibility features of this probe head overcome the probing challenges faced with the smaller pads and narrower spacing in such small devices..

This probe head configuration supports the highest bandwidth and provides the full bandwidth signals (1134B: 7 GHz, 1132B: 5 GHz, 1131B: 3.5 GHz, and 1130B:

1.5 GHz) and the lowest capacitive loading for measuring both single-ended and differential signals.

This probe head connects easily to an InfiniiMax probe amplifier using the bullet adapter shipped with the probe head.

For connection to a DUT, it has pre-wired probe tip leads that allow solder-in connection to very small, fine pitch targets.

NOTE

CAUTION

Before usage under high

temperatures

Discoloration after usage under high temperatures

When probing differential signals, the + and – connection of the MX0100A probe head can be determined when the probe head is plugged into the probe amplifier. The + and - indicators on the probe amplifier represent the + and - inputs on MX0100A probe head. When probing single-ended signals, ensure that the - input of the probe amplifier is connected to the ground of the DUT.

Extreme Temperature Testing with MX0100A Probe Head

The MX0100A probe head can withstand temperatures from –55°C to +150°C thereby making it suitable for extreme temperature environments such as temperature chambers. For extreme temperature testing, use the MX0100A probe head with the N5450B InfiniiMax extreme temperature extension cable.

InfiniiMax probe amplifiers cannot withstand extreme temperatures (–55°C to +150°C) that the MX0100A probe head can withstand. Be cautious not to subject these probe amplifiers to extreme temperatures. Using the N5450B extension cable with the MX0100A probe head physically separates the amplifier from the probe head and therefore eliminates the chances of amplifier’s exposure to extreme temperatures.

To know more about the N5450B extension cable and cautions associated with using an InfiniiMax probe head in extreme temperature testing, refer to “N5450B

Extreme Temp Cable Extension Kit" on page 22".

The MX0100A probe head components may undergo discoloration when used under high temperatures. Such changes do not, however, affect the probe head’s performance or measurement quality. The probe head maintains its specified frequency response and bandwidth over the operating temperature range (–55°C to +150°C), without any need for compensation or correction.

Trimming the Lead Wires of MX0100A Probe Head

Before soldering, trim the probe head’s lead wires matching your DUT’s geometry. You can choose from the following lead wire lengths:

• 135 mil (3.4 mm) - The probe head is shipped with this factory-trimmed standard

length. Use this lead wire length to accommodate variable-pitch targets. With this length, you get the maximum convenience in terms of longer reach and the available bandwidth is the full bandwidth of the probe amplifier being used (1134B: 7 GHz, 1132B: 5 GHz, 1131B: 3.5 GHz, and 1130B: 1.5 GHz).

• 60 mil (1.5 mm) - If your DUT’s geometry allows you to use shorter lead wire

length, trim the wires to this length to get the maximum performance. Use this lead wire length to accommodate small fine-pitch targets. The available bandwidth is the full bandwidth of the probe amplifier being used (1134B: 7 GHz, 1132B: 5 GHz, 1131B: 3.5 GHz, and 1130B: 1.5 GHz).

You need to specify your choice of lead wire length (3.4 mm or 1.5 mm) in the Probe Configuration dialog box of the Infiniium software GUI. This allows the software to load the appropriate s parameter file applicable to that wire length. The s parameter file adjusts the frequency response to enhance the measurements accuracy.

NOTE

To properly trim the probe head’s lead wires

1 Use the Keysight supplied trim gauge template that is included as part of the

MX0100A probe head kit.

Figure 18 MX0100A Trim Gauge Template (MX0100-94302)

2 Using tweezers, place the lead wire over the outline of the lead wires as shown

on the trim gauge template. The trim gauge template displays two lengths:

3.4 mm and 1.5 mm. Choose the correct length as per your DUT.

3 Using the cutting tweezers, trim the lead wires even with the trim lines.

You can spread the probe head’s lead wires within the range of 0mm to 7mm span without causing any significant variation in its available bandwidth.

Soldering an MX0100A Probe Head to DUT

The tools included in the MX0102A soldering toolkit can be of great use while soldering the MX0100A probe head to DUT (see page 29). You may purchase this toolkit separately.

To solder the probe tip lead wires to DUT

1 Trim the length of the MX0100A probe head lead wires to match your DUT’s

geometry (see page 40). You may use the cutting tweezers (Keysight part number 8710-2838) included in the Soldering toolkit.

1130B-Series Probes User’s Guide 41

2 Using Probe Heads

NOTE

Apply flux to both DUT and MX0100A probe tip lead wires. Always use plenty of flux, even if your solder already contains flux. This cleans the solder joint and allows for easier flowing solder and quicker dwell times.

3 Add solder to existing test points on DUT, if necessary. Heat momentarily and

do not dwell any longer than necessary!

4 Connect the MX0100A probe head’s lead wires to DUT by positioning these

wires on DUT and then reflowing joint while heating momentarily. .

Keep the temperature as low as possible while still reflowing the solder at the joint of concern. The following are some of the useful tips to maintain low temperature during soldering.

- A temperature-controlled soldering iron is the best way to do this. Set it for no more than 350

C if using standard lead-free solders and 150oC for

tin-bismuth solder.

- Do not rest a soldering iron on a probe joint for more than a few seconds.

5 Provide strain-relief to the probe head by taping its mid portion to a flat surface

such as a tabletop using the double-sided foam tape (such as Keysight part

MX0100A Probe Head Handling Precautions

One of the advantages of the MX0100A probe head is its reusability feature. This section describes some of the cautions and tips on how to properly handle the MX0100A probe head to prevent damage and maintain high performance and reusability of the probe head.

1130B-Series Probes User’s Guide 43

2 Using Probe Heads

To prevent damage and ensure reusability of the MX0100A probe head

• After you have connected the MX0100A probe head electrically to a DUT via solder, it is best to secure it mechanically as well. Always provide strain relief to the probe head setup using putty, velcro, low temperature hot glue, or double-sided foam tape to prevent any unnecessary strain to the probe head and to protect delicate connections.

• Strain relief is recommended at the probe head and amplifier housings as well as at the probe head cable.

Figure 19 Example of a properly strain-relieved MX0100A probe head setup

• While moving a soldered MX0100A probe head, always ensure that you do not twist, pull, tightly bend, or apply force near the probe head’s cable housing.

Figure 20 Example of correct movement of MX0100A probe head

Figure 21 Example of incorrect movement of MX0100A probe head

• Use a microscope setup while performing soldering/de-soldering tasks. A microscope with the following features is recommended.

• Binocular eyepieces

• Adjustable magnification (at least 20x)

44 1130B-Series Probes User’s Guide

Using Probe Heads 2

• Good working distance from the sample (at least 4 inches)

• Adjustable arm

• Integrated ring light around the objective lens

• Ensure that there is less thermal stress on the probe head as well as DUT by:

• Using a high quality temperature controlled soldering iron with the tip

temperature set as low as possible (just high enough to melt the alloy).

• Using a low temperature solder alloy such as SAC (Tin / Silver / Copper)

with 220

C melting point), or tin-bismuth solder with 138 oC melting point.

• Do not apply heat on the probe tip leads for a time period longer than two seconds.

• Use a small solder iron tip (<1mm is recommended).

• No clean (non-conductive) and less acidic flux is recommended.

• While disconnecting the probe head from the MX0103A bullet adapter:

• either gently pull the bullet adapter from the probe head by hand

• or engage a flat screwdriver on the notch provided on the bullet adapter and

gently disconnect the probe head from bullet adapter.

1130B-Series Probes User’s Guide 45

2 Using Probe Heads

To check the MX0100A probe head for any damage

You can use a Digital Multimeter to check the resistance measurement of your MX0100A probe head. If the resistance measurement between the probe head’s tip and tail is 25.2 kohm, then the probe head is usable,

Figure 22 Resistance measurement for an undamaged MX0100A probe head

For a damaged probe head, the resistance measurement between the MX0100A probe head tip wire and the center conductor of the SMP connector of the MX0100A is displayed as Infinite.

Figure 23 Resistance measurement for a damaged MX0100A probe head

Replacing an MX0100A Probe Tip Lead Wire

Use the following procedure to install or replace the lead wires on the MX0100A probe head in the event of damage or break off due to use. Depending on your probing application, you can order either 9 mil or 10 mil wire as listed in the following table. These wires are also included in the Keysight MX0102A Soldering Toolkit (see page 29 for details).

table. You may use a double-sided foam tape (Keysight part number 0460-3122 included in the MX0102A Soldering Toolkit). Keep the lead wires solder joints off the raised base to facilitate soldering. Cover the entire probe head tip with Kapton tape while ensuring that the lead wires solder joints are fully exposed for soldering.

2 Remove the damaged lead wire from the via by grabbing it with tweezers and

pulling up very gently. Touch the soldering iron to the solder joint just long enough for the lead wire to come free of the probe head tip.

To avoid burning and damage to the probe head, do not keep the soldering iron in contact with the tip any longer than necessary. The solder joint quickly melts and releases the wire.

3 Position the end of the new lead wire (Keysight part number MX0102-21302 or

MX0102-21303 included in the MX0102A Soldering Toolkit) over the via hole. Touch the soldering iron to the side of the hole. When the solder in the hole

1130B-Series Probes User’s Guide 47

2 Using Probe Heads

melts, the lead wire will fall into the hole. Remove soldering iron as soon as the lead wire falls into the hole..

4 Apply flux on the solder joint, Then apply a small amount of solder to the tip of

the soldering iron. Touch the solder tip (with the solder on it) to the solder joint. Do not dwell on the joint with the solder iron any longer than needed. The solder should flow off the soldering iron tip into the joint. If it does not flow, then sufficient flux may not have been used.

5 Cut the extra wire off using a cutting tweezer (Keysight part number 8710-2838

included in the MX0102A Soldering Toolkit).

2. E2677B Differential Solder-in Head with Full BW Resistors

This probe configuration provides the full bandwidth signals and the lowest capacitive loading for measuring both single-ended and differential signals. This head allows a soldered connection into a system for a reliable, hands-free connection. At the tip it uses a miniature axial lead resistor with 8 mil diameter leads which allows connection to very small, fine pitch targets.

1130B-Series Probes User’s Guide 49

2 Using Probe Heads

CAUTION

NOTE

Do not solder in resistor leads with a big ball of solder right next to the resistor body. Normally the nickel lead will limit the heat transfer to the resistor body and protect the resistor, but if a ball of solder is right next to the resistor body on the lead, the resistor may come apart internally.

When soldering leads to DUT always use plenty of flux. The flux will ensure a good, strong solder joint without having to use an excessive amount of solder.

Strain relieve the micro coax leading away from the solder-in tips using hook-and-loop fasteners or adhesive tape to protect delicate connections.

Before using the resistors, the resistor wires must be cut to the correct dimensions. For the correct dimensions see “Replacing Resistors on E2677B/9B Solder-In Probe

Heads" on page 74".

3. E2678B Differential Socketed Head

NOTE

This probe configuration allows a removable, hands-free connection that provides full bandwidth with a minor increase in capacitance over the probe head for probing differential and single-ended signals. Additionally, 3.6 cm resistor tip wire accessories are provided for high fidelity lower bandwidth probing of signals with very wide spacing. It is recommended that a 25 mil diameter plated through hole on the board for mounting the lead resistors.

The E2678B is a direct replacement for the E2678A that provides a more robust connection between the E2678B head's socket and printed circuit board. The E2678B’s performance and fit are identical to that of the E2678A.

NOTE

PC Board Target Dimensions

Shaping the Resistors

To install or repair resistor leads. Refer to the information found in this section.

The spacing for the socketed tip differential probe head is 0.100 inch (2.54 mm). For soldering on a PC board, the targets can be two vias that can accept the 0.020 inch (0.508 mm) diameter resistor leads. A via of 0.025 inch (0.0635 mm) diameter is recommended. If soldering a resistor lead to a surface pad on your PC board, the resistor leads can be bent in an "L" shape and soldered down. A pad size of at least

0.030 x 0.030 inch (0.762 mm x 0.762 mm) is recommended.

Before installing the 82W resistors (01130-81506) onto your device under test, the resistor wires must be trimmed using diagonal cutters and bent to the correct dimensions as shown in Figure 26. Use tweezers, to place the resistor body inside the rectangle of the supplied trim guage. Use diagonal cutters to trim the leads even with the trim lines.

The N2851A QuickTip probe head is used with an N2849A QuickTip and together they provide the following advantages:

• Easy-to-make secure magnetic mechanical connection between the probe head and QuickTip. Three magnets in the head connect the two sides of a differential signal and a ground. No latch lever is used!

Permanently solder any number of QuickTips to your DUT as shown in Figure 35 on page 61. Because the probe head is magnetically connected (instead of mechanically connected) to the QuickTip, you can effortlessly connect and disconnect to each QuickTip. For best performance, position the QuickTip vertically on the DUT. The N2849A QuickTip has two signal leads and two ground leads. The ground leads have minimal effect on your differential measurements. However, if you are making only differential measurements you can optionally cut off the ground leads or fold them out of the way. Be aware that without the ground leads, the mechanical stability of the QuickTip will be reduced and you will need to stabilize the probe head.

Connecting a QuickTip to the DUT

Before connecting the QuickTip head to the tip, use the tack-putty (N5439-65201) included with the N2848A QuickTip probe head or the N2787A 3D probe positioner for securing the probe amplifier to a rigid body near the DUT.

Use the following tips when soldering the QuickTips to your DUT:

• Orient the QuickTip vertically as shown in Figure 35 on page 61.

• Solder the four leads to vias or surfaces.

Always mechanically strain-relieve the QuickTip head before using to protect both your probe accessories and DUT from damage.

Resistor and wire leads on the QuickTip are factory trimmed to the proper length for use. Adding wire length to the tip of the mini-axial lead resistors or to the ground leads will degrade the performance of the probe.

Soldering the ground wires is not required when making differential or single-ended (+ or – leads) measurements.

• When soldering to a via, always trim the lead close to the via’s underside.

• If a lead is to be soldered to a surface and not a via, make a stronger solder joint by bending the end of the lead 90°. For signal leads, bend the wire approximately half way between the resistor and the end of the wire. Bend the ground leads at about the same distance.

Be careful not to damage the tip wires when handling the QuickTips. Wires can be carefully reshaped with tweezers or fingers if necessary.

The QuickTips are very fragile. They must be manufactured in this way in order to meet the high-performance, high bandwidth applications they are intended for. Be extremely careful when handling.

Cleaning the Magnetic Connections

If the three magnetic connections in the head become dirty, clean the connections using the following steps:

1 Use compressed air or a cloth to remove any loose dirt.

2 Gently rub a small piece of tack putty (supplied with the probe) against the

magnetic connections to clean off any remaining surface grime.

12. E2678B Differential Socketed Head with Header Adapter

This probe configuration can be used to connect to 25 mil square pin headers with 100 mil spacing such as those used in USB testing. The header adapter is recommended for use with the 1130B and 1131B InfiniiMax probes.

If the header adapter is used with higher bandwidth probe amplifiers such as the 1132B (5 GHz) or the 1134B (7GHz), the rise time of the input signal should be slower than ~150 ps (10% to 90%) to limit the effects of resonances in the adapter.

All of the specifications and characteristics of the header adapter are the same as those for the socketed differential probe head except for the input capacitance shown in Table 25.

Table 25 Characteristic Capacitance

Cg 0.54 pF

Cdiff 0.70 pF Differential mode capacitance is Cm + Cg/2

Cse 0.97 pF Single-ended mode capacitance is Cm + Cg

To adapt the 01130-21303 damped wire accessory from solder-in to plug-on, solder the tip into the 01131-85201 square pin socket and then slip the 01131-41101 heat-shrink sleeve over the solder joint and heat the heat-shrink tubing with a heat gun. This allows the damped wire accessories to be used to plug onto 25 mil square pins.

NOTE

Using Probe Heads 2

1 Use the vise or clamp to position the tip an inch or so off the work surface for

easy access.

If using a vise, grip the tip on the sides with light force. When tightening the vise, use light force to avoid damaging the solder-in probe head If using a tweezers clamp, grip the tip either on the sides or at the top and bottom.

Figure 45 Clamping the Probe Head

2 If you need to remove an existing or damaged lead wire, grab each resistor lead

or body with tweezers and pull very gently up. Touch the soldering iron to the solder joint just long enough for the resistor to come free of the probe head tip.

To avoid burning and damage to the pc board, do not keep the soldering iron in contact with the tip any longer than necessary. The solder joint has very low thermal mass, so the joint quickly melts and releases the wire.

Make sure soldering iron tip is free of excess solder.

3 In needed, fill the mounting hole with solder in preparation for the new wire.

4 Use the flux pencil to coat the solder joint area with flux.

5 Prepare the mini-axial lead resistor for attachment to the head’s pc board. The

lead to be attached to head’s pc board will have a 90° bend to go into through hole in the tip pc board.

6 Using tweezers, place the resistor body inside the rectangle of the trim

template.

CAUTION

NOTE

Do not use the wrong value of resistor at the wrong length.

Using Probe Heads 2

10 Holding the resistor lead or wire in one hand and soldering iron in the other,

position the end of the resistor lead (after the 90° bend) over the solder filled hole. Touch the soldering iron to the side of the hole. When the solder in the hole melts, the resistor lead will fall into the hole. Remove soldering iron as soon as lead falls into the hole.

The thermal mass of the joint is very small, so taking extra time with the soldering iron in an attempt to ensure a good joint is not needed.

Make sure the zero ohm resistor is used for ground leads on the E2679B single-ended probe head.

For the E2677B differential solder-in probe head, the + and – connection can be determined when the probe head is plugged into the probe amplifier, so which way the tip is soldered in is not important.

Calibration for Solder-In and Socketed Probe Heads 80 Calibration for Hand-held Browser Probe Heads 87 Calibration for N5380A/B SMA Probe Heads 89

Calibrating the InfiniiMax probes (1168B, 1169B, 1130B, 1131B, 1132B, 1134B) is done using the E2655C Deskew and Calibration Kit. The kit contains the following parts:

• SMA (male) to SMA (male) adapter

• SMA (male) to BNC (female) adapter

• BNC (male) to SMA (male) adapter

•50Ω SMA Terminator

• De-skew Fixture

When the probe has been calibrated, the dc gain, offset zero, and offset gain will be calibrated. The degree of accuracy specified at the probe tip is dependent on the oscilloscope system specifications.

This chapter contains procedures showing vertical and skew calibration for solder-in differential probe head, the differential browser probe head, and the SMA probe head. The procedures can also be applied to all of the different InfiniiMax probe configurations and for the 11560 and 1150A series active probe configurations.

3 Calibrating Probes

NOTE

Calibration for Solder-In and Socketed Probe Heads

Calibration of the solder-in and socketed probe heads consists of a vertical calibration and a skew calibration. The vertical calibration should be performed before the skew calibration. Both calibrations should be performed for best probe measurement performance.

Before calibrating the probe, verify that the Infiniium oscilloscope has been calibrated recently and that the calibration D temperature is within ±5°C. If this is not the case, calibrate the oscilloscope before calibrating the probe. This information is found in the Infiniium Calibration dialog box.

Step 1- Connecting the Probe for Calibration

The calibration procedure requires the following parts.

• BNC (male) to SMA (male) adapter

•Deskew fixture

•50Ω SMA terminator

1 As shown in Figure 49 on page 81, connect BNC (male) to SMA (male) adapter

to the deskew fixture on the connector closest to the yellow pincher.

2 Connect the 50Ω SMA terminator to the connector farthest from the yellow

pincher.

3 Connect the BNC side of the deskew fixture to the Aux Out BNC of the Infiniium

oscilloscope.

4 Connect the probe to an oscilloscope channel.

5 To minimize the wear and tear on the probe head, the probe head should be

placed on a support to relieve the strain on the probe head cables.

6 Push down on the back side of the yellow pincher. Insert the probe head

resistor lead underneath the center of the yellow pincher and over the center conductor of the deskew fixture. The negative probe head resistor lead or ground lead must be underneath the yellow pincher and over one of the outside copper conductors (ground) of the deskew fixture. Make sure that the probe head is approximately perpendicular to the deskew fixture.

For the socketed probe head, insert two properly trimmed 82Ω resistors into the sockets.

7 Release the yellow pincher.

To ensure contact, pull up on the back side of the yellow pincher to ensure good contact between resistor leads and the deskew fixture.
