Reliable Connections Ensure Accuracy
Signal frequency content drives probing solutions
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.
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.
Which Logic Analyzer?
Keysight logic analyzers have two methods of connection to the probes. One
uses a 3M-style connector with two rows of 20 pins on 0.1-inch centers,
as illustrated in Figure 1.1. Probes for these analyzers are identified in this
document as “for analyzers with 40-pin pod connectors.”
The other style uses a 90-pin, high-density connector, as illustrated in Figure
1.2. Probes for these analyzers are identified in this document as “for analyzers
with 90-pin pod connectors.”
Currently available Keysight logic analyzers in these two groups are as follows:
40-pin pod connector (pages 10 to 36)

16910A
16800 Series benchtop analyzers

16962A and U4154A
– 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.
– Ruggedness
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.
– Performance
Keysight logic analyzers have frontend 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.
Other considerations
Figure 1.2. 90-pin pod connector
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 40-pin Logic Analyzers
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 2.1) at the probe tip and a shielded resistive transmission
line. The advantages of this system are:
– High input impedance. See Figure 2.1.
– Signal ground at the probe tip for high-speed signals.
– Inexpensive, removable probe tip assemblies.

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 2.2, along with the replacement part numbers for individual
components in Figure 2.3.
Each probe lead is a 12-inch, twisted-pair cable connected to the probe cable at the
probe housing (see Figure 2.3). 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 2.6 for IC test clips available from commercial sources.)

IC clips
The surface-mount device IC clip with

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 2.5.
Probe ground leads
RC network housing
Grounding
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).
For moderate rise times (greater than
2 ns), it may be acceptable to ground
every other (or every fourth) ground
connection to the target.

Probing Solutions for 40-pin Logic Analyzers
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.

Probing Solutions for 40-pin Logic Analyzers
Soft Touch Connectorless Probing
High-density, high-performance probes
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.
E5404A Pro Series soft touch
connectorless probe
The E5404A is a 34-channel single-ended
Pro Series soft touch connectorless
probe compatible with all Keysight

The soft touch probes are attached to
the PC board using a retention module
which ensures pin-to-pad alignment
and holds the probe in place. A board
thickness of up to 2.54 mm (0.100 inch)
is recommended. Insert the retention
module into the board, noting the keying
pin, and solder the four alignment pins to
the backside of the board.

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 3.18 shows
the equivalent load for the E5339A, and Figure 3.19 shows the equivalent load for the
E5346A. Figure 3.20 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 Er=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 (Tr). If it is, the E5346A, E5339A, or E5385A can be used for
connection.
For example, if Er=4.9, a 2.5 inch probe hookup stub generates a propagation delay of
400 ps. If Tr is > 2 ns, the E5346A, E5339A, or E5385A is a viable probing choice.
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, surface mount isolation network 5062-7396, 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 3.25. 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.

Options for on-board
terminations for the E5351A
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 3.26 for
schematic and pinout.
– Use discrete components. Refer
to Figure 3.25 for recommended
components and equivalent load.
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.

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.

As shown in Figure 3.26, the 5062-7396
SMT isolation network supports six logic
analysis channels. The size of the part
allows you to repeat the pattern in Figure
3.26 to accommodate multiple parts
stacked end-to-end for the number of
channels needed in your application.
Three of these SMTs are required for each
probe cable. The process for using the
ceramic hybrid isolation network is similar
to the process for an LCC package. Due
to the small part size, thermal expansion
mismatch during solder reflow should not
be a problem. Capacitance also remains
stable with temperature changes.

Notes on using the 5062-7396
SMT part
Keysight currently recommends a twostep process in soldering the SMT part
to the board. The first pass places solder
paste on those pads with vias. Application
of heat allows the via to fill with solder. (If
only one solder step is used, the solder
wicks away from the part into the via and
a solid connection will not be made with
the part.) The next pass places solder
paste on all of the pads.

Support shrouds
A support shroud is recommended to
provide additional strain relief between
the probe and the connector, as shown
in Figures 3.21 and 3.23. Two plated
through-holes are required on the target
board. The shroud is mounted directly
to the target board using the throughholes. This places the shroud around the
connector, providing solid mechanical
strain relief. Connector kits are available;

Probing Solutions for 90-pin Logic Analyzers
Soft Touch Connectorless Probing
Seven 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.

General-Purpose Probing Flying Lead Probing Accessories
Wedge adapters
The Keysight Wedge technology provides
very reliable probing of a few channels
on 0.5 mm and 0.65 mm pitch QFPs. No
clear area is required around the device.
Each Wedge of the probe slides between
the legs of the QFP. The side of each
Wedge probe contacts the package legs.
An insulation core electrically isolates
the sides of each Wedge (see Figures 9.1
and 9.2). Various 3-signal, 8-signal, and
16-signal probes are available (see
Table 9).

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.
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.
