The new Agilent E5400-pro series soft touch probes are
ultra- low-load connector- less probes that work with the
Agilent logic analysis modules. The probes attach to the PC
board using a retention module which ensures pin- to- pad
alignment and holds the probe in place.
• The E5402A- pro series probe is a low-profile right- angle
34- channel single- ended connectorless soft touch probe
(for analyzers with 90-pin cable connectors).
• The E5404A- pro series probe is a 34-channel single- ended
connectorless soft touch probe (for analyzers with 40- pin
cable connectors).
• The E5405A- pro series probe is a 17-channel differential
connectorless soft touch probe (for analyzers with 90- pin
cable connectors).
• The E5406A- pro series probe is a 34-channel
single- ended connectorless soft touch probe (for analyzers
with 90- pin cable connectors).
Use the following information to design your target system
board for use with the Agilent soft touch probes.

Installation Instructions
1 Use the information provided in Chapter 2 to design pads
on your board and holes for mounting the retention
module.
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.
2 Use flux as necessary to clean the board and pins before
soldering the retention module to the board.
3 If your board has Organic Solder Preservative (OSP)
finish, apply solder paste to the footprint pads prior to
reflow or hand soldering.
Typically, dipped and coated finishes do not require extra
solder paste.
4 Attach the retention module to the board from either the
top or bottom of the board:
Top- side attach
Can be used with most board thicknesses.
a Insert the retention module into the board noting the
keying pin.
b Solder alignment pins from the top ensuring that solder
is added until a fillet is visible on the pin.

Insert
Figure 1 Solder retention module from the top.
Bottom- side attach
Can be used for board thickness of 2.54 mm (0.100 in.) or
less.
a Insert the retention module into the board noting the
keying pin.
b Solder the alignment pins to the back side of the
board.
5 Insert the probe into the retention module.
Ensure proper keying by aligning the Agilent logo on the
probe with the one on the retention module and place the
probe end into the retention module.
6 Alternate turning each screw on the probe a little until
both screws are finger tight like you would attach a cable
to your PC.

The E5402A-Pro Series Low-profile Right-angle 34-channel
Single-ended Soft Touch Probe
The Agilent E5402A- pro series probe is a 34-channel,
single- ended, soft touch probe compatible with the Agilent
logic analysis modules listed in Table 1 on page 12. It is
capable of capturing data up to the rated maximum state
(synchronous) analysis clock rates of all the supported
analyzers, with signal amplitudes as small as 250 mV
peak-to- peak. A retention module must be installed on the
target system board to attach the probe to the board. There
is a key on the retention module that indicates the egress of
the cable when the probe is attached.
A kit of five retention modules are supplied with each
probe. Refer to “Ordering retention modules" on page 13 for
information on ordering more.
See “Mechanical Considerations" on page 19 for

The E5386A Half-channel Adapter (for use with the 16760A logic analyzer)
The E5386A Half-channel Adapter is intended to be used
with the Agilent 16760A logic analyzer in half-channel state
mode and supports the E5402A, E5405A, and E5406A
probes.
The E5386A Half-channel Adapter has its own ID code.
When using the adapter, the 16760A logic analyzer
recognizes its code rather than that of the probe which is
attached to the target. Therefore, the user interface format
menu doesn't automatically set thresholds to the proper
values. You need to go into the threshold menu and select
(differential, custom, or standard settings).
E5386A
half-channel adapter
When using the adapter in half- channel state mode:
• Clock-bits are not available in half- channel state mode
(although JCLK on the master is still used).
• Be sure to connect Master pod 1 of the logic analyzer to
the upper bits, 8- 15 + clk, on the half- channel adapter.
This is necessary to connect the clock in the system
under test to the logic analyzer system clock.
• Using the E5386A does not reduce the performance of the
16760A logic analyzer and the soft touch probes.
If the E5386A is used in full- channel state mode, the
thresholds on the unused (odd) bits are floating. This could
result in spurious activity indicators in the format menu.
