Probing for Memory System Validation

Keysight Technologies, Inc. has the measurement tools you need to validate the very

latest memory technologies. These include logic analyzers, oscilloscopes and software

for automated compliance, decode, and protocol checking. To complement our high

speed digital instruments and software, Keysight offers probing solutions with a

comprehensive range of Ball Grid Array (BGA) interposers. When positioned between

the processor memory controller and the memory device, the interposers allow you to

make signal quality or protocol measurements with minimal effect on the system-under-

test. You can choose from a large selection of existing BGA interposers or work with

Keysight’s Application Engineers to define customized probing solutions for your specific

needs.

Refer to the following publications for information on available DDR/LPDDR BGA

interposers.

Reliable Connections Ensure Accuracy

Signal frequency content drives probing solutions

– Impedance

High input impedance ensures

minimum intrusion on your circuit.

Although many probes might be

acceptable for lower frequencies,

capacitive loading becomes

significant at higher frequencies. The

Keysight probing products perform

over a wide frequency spectrum.

Faster clock rates demand tighter timing tolerances, such as setup and hold

specifications. Systems with faster clock rates usually have shorter rise and fall times.

Signals with shorter transition times have more high frequency content and are more

susceptible to high frequency analog problems such as cross talk, reflections, ground

bounce, noise and emissions. Susceptibility of a system to analog problems relates to

the transition times of the signals, not the clock rate. A system with slow transition times

cannot have high clock rates. However, it is possible for a system with slower clock rates

to have signals with very fast transition times.

– Ruggedness

General-purpose probing solutions provide the analog bandwidth required to run

each logic analyzer module at its maximum clock rate. The high input impedance of

these probes, especially at high frequencies, presents a minimal load to most systems.

Systems that are operating with little margin should be designed with consideration for

both the system components and the input impedance of the probing solution being

used during debug. Input impedance specifications or equivalent load diagrams can be

found for each of the probing solutions described in this document.

Probes with quality mechanical

design provide solid electrical

connections. Intermittent open

circuits would only add one more

variable to your debugging equation.

Keysight probes are mechanically

designed to relieve strain and ensure

rugged, reliable connection.

– Immunity to Noise

Electromagnetic noise can corrupt

data captured by the logic analyzer.

Keysight probing solutions are

designed for a high immunity to

transient noise.

Which Logic Analyzer?

For logic analyzers with 160-pin front panel connector, use probes identified in

this document as “Direct-connect probes.”

For logic analyzers with cables that use a 3M-style connector with two rows of

20 pins on 0.1-inch centers, as illustrated in Figure 1.1, use probes identified in

this document as “for analyzers with 40-pin pod connectors.”

– Performance

Keysight logic analyzers have

front-end circuitry that supports the

state and timing specifications of

the analyzer. This circuitry, together

with the Keysight probing solutions

described in this document, will

accurately capture the target signals

at the specified clock rates.

For logic analyzers with cables that use a 90-pin, high-density connector as

illustrated in Figure 1.2, use probes identified in this document as “for analyzers

with 90-pin pod connectors.”

Other considerations

Physical connection compatibility

between various Keysight probes may

allow you to mix and match a variety

of probes and accessories. However, a

probe accessory designed for slower

clock speeds will not deliver high-speed

target performance simply because it

is used with a higher speed analyzer

module. Also, the serial connection of

multiple probe leads and/or accessories

will degrade signal integrity.

Probing Solutions for 90-pin Logic Analyzers

Soft Touch Connectorless Probing

Several options are available for connecting Keysight logic analyzers with 90-pin pod

connectors to a target system using mass connections.

Keysight Pro Series soft touch connectorless logic analyzer probes

Keysight has developed connectorless logic analyzer probes based on soft touch

probing technology. Connectorless logic analyzer probing removes the connector that

is traditionally attached to the target board and replaces it with an array of probe pads.

This reduces the probe load on the target by eliminating the loading associated with

the physical body of the connector. Additionally, this streamlines the design flow by

eliminating the need to assign a logic analyzer connector to the bill of material of your

board, procuring those connectors and then having them loaded onto your board.

Keysight’s soft touch connectorless probes use micro spring-pin technology to provide

reliable contact which is not dependent on the planarity of the PC board or the plating

processes used to fabricate the board. No special cleaning processes are required when

using Keysight’s soft touch probes.

The new Keysight Pro Series soft touch connectorless probes offer a 30% smaller

footprint than the original soft touch probes and are the basis for the industry standard

connectorless probing footprint.

The probes use a retention module that ensures soft touch pin-to-PC board pad

alignment and holds the probe in place while in use. The Pro Series soft touch uses a

“top-side” mountable retention module. The retention module is mounted on the same

side of the board as the probing footprint so there is no need to access the back-side

of the board. Because there is no requirement for the retention module pins to extend

beyond the back-side of the board, the retention module is compatible with virtually any

board thickness.

The U4207A is only for use with Keysight RC (resistor/capacitor) BGA interposers, such

as the W6602A. Please refer to the U4200A Series user guide for the specific Keysight

RC BGA interposer for specific information regarding connecting the U4207A.

The Keysight W6602A+U4207A passively monitors the LPDDR4 200 ball DRAM package.

After tuning the Keysight analyzer, Command/Address bits can be reliably captured up

to 3200 MT/s. At some data rates, the analyzer may not be able to provide an error-free

capture of all DQ data bits.

Physical dimensions of the U4207A are identical to the U4206A. Electrically, the probes

are very different. The U4206A contains the RC tip network for the U4164A internally.

The U4207A is zero Ω internally and is designed only to be used with Keysight BGA

interposers with the tip RC network for the U4164A designed onto the BGA interposer.

CAUTION: Connecting the U4207A to a footprint without the RC tip network can damage

the U4164A module.

The U4206A is designed to be used with either the quad state mode or ¼ channel

10 GHz timing mode of the U4164A logic analyzer module. For use in quad state mode

only, the U4207A includes two flying leads to connect additional clock qualifier signals

into the clock inputs on Pods 3 and 7 of the clocking module.

Please refer to the U4164A installation guide for specific details on the operation of the

40-pin and 90-pin Logic Analyzers Probe Cables

Signal line loading

Any probed signal line must be able to supply a minimum of 600 mV (unless noted

otherwise — see probe of interest) to the probe tip while the probe is connected to the

system. The maximum input voltage of each probe is ± 40 volts peak (unless noted

otherwise — see probe of interest).

Probe cables

The probe cable (see Figure 10.1 and Table 10) contains 16 signal lines and two clk lines,

two +5 volt power lines, and ground lines for each of the signal/clock and power lines.

All of these lines are contained in a 4.5-foot cable. The probe cable is included with the

logic analyzer. The cable grounds are chassis (earth) grounds, not “floating” grounds.

The two +5 volt power lines can be used to power active probing systems. Consult the

specifications for the individual logic analyzers or logic analyzer cards for the maximum

allowable current through each +5 volt power supply.

Figure 8.1. Typical logic analyzer probe cable.

Caution: These +5 volt power lines MUST NOT be connected to the target’s power

supply.

Caution: Be careful when using straight wire probe leads, one common ground, or

RC networks located far from the target. These circumstances increase the impact

of analog effects such as crosstalk and EMT susceptibility, which contribute to

measurement errors.

General-Purpose Probing

E5383A 17-channel single-ended flying lead probe

Ideal when only a few lines may need to be probed or probe points are distributed across

a target. The E5383A includes a set of 20 IC test clips and five ground leads.

Logic analysis general-purpose probes

General-purpose probing requires connecting probe leads to individual signal lines. This

method is most convenient for a small to moderate number of signals, is very flexible,

and can be used in conjunction with other probing methods.

Note: Any probed signal line must be able to supply a minimum of 600 mV to the probe

with the specified loading.

The standard probing system

The standard probing system consists of IC clips, probe leads, probe housing and

probe cable. Because it is passive, the standard probing system is smaller, lighter, and

much easier to use than active probing systems. This passive probing system is similar

to a probing system used on a high frequency oscilloscope. It consists of an isolation

network (as shown in Figure 9.1) at the probe tip and a shielded resistive transmission

line. The advantages of this system are:

– High input impedance. See Figure 9.1.

– Signal ground at the probe tip for high-speed signals.

– Inexpensive, removable probe tip assemblies.

Tip isolation network

Equivalent load

Probe leads and lead sets

Probe leads are configured into lead sets, which can probe 16 data channels with

ground, one clock channel, and a common ground. A 17-channel probe lead set

(E5383A) is shown in Figure 9.2, along with the replacement part numbers for individual

components in Figure 9.3.

Each probe lead is a 12-inch, twisted-pair cable connected to the probe cable at the

probe housing (see Figure 9.3). The probe tip includes a signal lead, a connector for a

ground lead, and the isolation network.

The signal and ground leads can be connected directly to the target system. This

requires installing 0.63 mm (0.025 inch) square pins, or round pins with a diameter of

between 0.66 mm (0.026 inch) and 0.84 mm (0.033 inch) directly on the board. An IC

test clip can also be used. The same specifications apply for the pin dimensions of the

test clip. (See Figure 9.6 for IC test clips available from commercial sources.)

IC clips

The surface-mount device IC clip with

twin hooks (part number 5090-4833,

containing 20 IC clips) is designed for fine

surface-mounted component leads. The

twin hook 0.5 mm IC clip (part number

10467-68701, containing four 0.5 mm

IC clips), is very useful for 0.5 mm pitch

components. See Figure 9.5.

Probe ground leads

RC network housing

Grounding

SMT IC clip

There are three methods of grounding

the probe system. First, the entire probe

lead set can be grounded through the

common ground. This requires only one

connection, but is not recommended

because it will cause poor signal fidelity

in systems with fast transition times. The

recommended method is to individually

ground each probe lead. This yields

optimal signal fidelity and is required for

signals with faster transition times

(< 4 to 5 ns).

Designing for Logic Analysis Probing

Keysight recommends that targets with probing constraints have connectors designed

into the prototype versions of the product for effective hardware and software debug.

The following should be considered when designing with connectors:

– Select the appropriate connector technology for your target speed and target

density.

– Carefully select all lines for routing to the connectors that may be needed for

debug.

– Group the lines at each connector for your probing convenience. For example,

Keysight may have written an inverse assembler for your device that has a

preconfigured signal order. Before designing, refer to the documentation for this

inverse assembler for essential signal lines and order.

– Keep the routing to connectors as short as possible to minimize target impact and

provide accurate data.

– Examine the impact of probing isolation networks designed into the target versus

the isolation network products offered by Keysight.

An isolation network must be located between the target and the logic analyzer. It can

be located on the target board in through-hole or SMT parts. It can also be attached to

the logic analyzer cable with the probe leads (the isolation network is molded into the

end of the probe); or the Keysight 01650-63203 isolation adapter with self contained

isolation networks can be used. Probe leads can be used with connectors but are not

the most convenient method. Direct connection of the connectors with the analyzer

cable (isolation network parts on the target) or with a probe or isolation adapter is the

faster, more convenient method.

Soft Touch Connectorless Probing

High-density, high-performance probes

E5404A Pro Series soft touch

connectorless probe

Keysight Pro Series soft touch connectorless logic analyzer probes

The E5404A is a 34-channel single-ended

Pro Series soft touch connectorless

probe compatible with all Keysight

logic analyzers that have a 40-pin pod

connector. It is capable of acquiring

data at the maximum rates of the logic

analyzer it is connected to.

Keysight has developed connectorless logic analyzer probes based on soft touch

probing technology. Connectorless logic analyzer probing removes the connector that

is traditionally attached to the target board and replaces it with an array of probe pads.

This reduces the probe load on the target by eliminating the loading associated with

the physical body of the connector. Additionally, this streamlines the design flow by

eliminating the need to assign a logic analyzer connector to the bill of material of your

board, procuring those connectors and then having them loaded onto your board.

Features

Keysight’s soft touch connectorless probes use micro spring-pin technology to provide

reliable contact which is not dependent on the planarity of the PC board or the plating

processes used to fabricate the board. No special cleaning processes are required when

using Keysight’s soft touch probes.

– No connector on the target board

– Top-side mount retention module

– Industry-standard connectorless

footprint

– 34 channels, single-ended clock and

data

The new Keysight Pro Series soft touch connectorless probes offer a 30% smaller

footprint than the original soft touch probes and are the basis for the industry standard

connectorless probing footprint.

– Extremely low, < 0.7 pF, equivalent

load capacitance

The probes use a retention module that ensures soft touch pin-to-PC board pad

alignment and holds the probe in place while in use. The Pro Series soft touch uses a

“top-side” mountable retention module. The retention module is mounted on the same

side of the board as the probing footprint so there is no need to access the back-side

of the board. Because there is no requirement for the retention module pins to extend

beyond the back-side of the board, the retention module is compatible with virtually any

board thickness.

– Capable of data rates > 2.5 Gb/s

(maximum rate dependent on

analyzer used)

– 500 mV p-p minimum signal

amplitude

– Robust and reliable soft touch

technology

Unused clock inputs can be used as data

inputs.

The E5404A (used with logic analyzers

with a 40-pin cable connector) uses the

same footprint, pinout, and retention

logic analyzers with a 90-pin cable

connector).

A kit of five retention modules is shipped

Mictor and Samtec Probing

High-Density, High-Performance

Keysight has developed high-density probing solutions based on the 100-pin Samtec

and AMP Mictor 38-pin connectors. The Keysight probes and adapter cables, E5346A,

E5339A, E5351A, and E5385A, provide a connection strategy to route your important

signals to the Keysight logic analyzer. Simply design the connectors onto the board for

the critical signals such as address, data, and status bits. The connectors consume a

minimal amount of board space. Each connector provides 32 channels of logic analysis

per connector and two clocks (unused clocks can be used as data). Connectors for use

with the E5385A, E5346A, E5339A, and E5351A can be purchased directly from AMP,

Samtec, or Keysight. See the “Related Information” at the end of this document.

Keysight Technologies E5346A, E5339A, and E5385A probes

The E5346A, E5339A, and E5385A probes include the required isolation networks for

the logic analyzer right at the probe tip, close to the target. The E5346A and E5385A are

designed to acquire signals with peak-to-peak amplitude as low as 500 mV. The E5339A

is designed to acquire signals as small as 250 mV peak-to-peak. Figure 9.24 shows

the equivalent load for the E5339A, and Figure 9.25 shows the equivalent load for the

E5346A. Figure 9.26 shows the equivalent load for the E5385A.

To use the E5346A, E5339A, or E5385A at high clock speeds, the following design

guidelines should be observed:

– Calculate the electrical length of the probe hookup stub.

– For PC board material with E_r=4.9, use a propagation delay of 160 ps/inch.

– Check that the propagation delay of the probe hookup stub is less than 20% of the

bus signal rise time (T). If it is, the E5346A, E5339A, or E5385A can be used for

r

connection.

For example, if E_r=4.9, a 2.5 inch probe hookup stub generates a propagation delay of

400 ps. If T is > 2 ns, the E5346A, E5339A, or E5385A is a viable probing choice.

r

The E5346A and E5339A use the AMP Mictor 38-pin connector. The E5385A uses a

100-pin connector manufactured by Samtec. Keysight recommends the E5394A or

E5385A for new applications, due to the reduced input capacitive loading and improved

isolation between adjacent channels.

Keysight E5351A 38-pin adapter cable

If the calculated electrical length of the required routing stub prohibits the use of the

Keysight E5339A, E5346A, or E5385A, the Keysight E5351A can be used with the

required isolation networks installed on the target.

The E5351A does not have its own internal isolation networks. When using the E5351A,

place the SIP isolation networks or equivalent discrete components very near the

target component for measurement. Ensure that the stub length between the target

component and the isolation network is short. The stub propagation delay should be

less than 20% of the bus signal rise time, as mentioned before. The transmission line

from the on-board isolation network to the Mictor connector should be designed for an

impedance in the range of 80 to 100 ohms (closer to 100 ohms is better). This length

should not exceed 3 to 4 inches, and all signal line lengths should be equal. Signal line

length variation should not cause propagation delay variation to exceed 20 ps between

signal lines.

Notes on using discrete components

Discrete components can be used in the design of the RC network. Keysight

recommends the circuit shown in Figure 9.31. To achieve the equivalent load shown in

the figure, trace lengths should be minimized by locating the RC network very near the

measured node. Actual load will be the stub length load added to the equivalent load in

the figure.

k

There are two options for isolating the

E5351A on the target PC board:

– Use the surface mount isolation

network, Keysight part number

5062-7396. Refer to Figure 9.32 for

schematic and pinout.

9 pF

10 pF

– Use discrete components. Refer

to Figure 9.31 for recommended

components and equivalent load.

Figure 9.31. Suggested on-board isolation network and equivalent load when using discrete

components to terminate the E5351A.

1. The effective input capacitance for on-board isolation networks is purely a function of geometry -

0.3 pF is about as low as can be achieved.

If you are operating at state speeds

above 200 MHz, you should use discrete

components for best results. Due to the

added electrical length of the E5351A

probe cable, the divider compensating

capacitors in the SIP, and surface-mount

isolation networks are not optimum for

the E5351A, but they are usable up to

200 MHz clock rates.

2. The equivalent load is the same when using the surface-mount isolation network, 5062-7396.

A support shroud is recommended to

provide additional strain relief between

the probe and the connector, as shown

in Figures 9.27 and 9.29. Two plated

through-holes are required on the target

board. The shroud is mounted directly

to the target board using the through-

Direct connection through

isolation adapter

Isolation adapters (Keysight part number

01650-63203) that connect to the end of

the probe cable are designed to perform

two functions. The first is to reduce the

number of pins required for the header

on the target board from 40 pins to 20

pins. This process reduces the board area

dedicated to the probing connection.

The second function is to provide the

proper RC networks in a very convenient

package. Figure 9.36 illustrates how the

isolation adapter physically connects to

the target system and the equivalent load

of the isolation adapter connected to a

Keysight logic analyzer. Figures 9.37 and

respectively. There are two 20-pin
