HP E5346A/E5351A
High-Density Adapter Cable
Installation Note
High-density adapter cables provide a convenient way to connect two
HP logic analyzer probe cables to a small area of a target system. The
HPE5346A cable has RCR networks in the cable end that connects to
the high-density AMP Mictor (Matched Impedance ConnecTOR)
connector. The HP E5351A cable does not have RCR networks, so
terminations must be made on the target system.

Installation overview
1 Attach the Mictor connector(s) to the target system. Use 38-pin
surface mount receptacles, AMP part number 2-767004-2.
2 Align the Mictor connector with the support shroud. Note pin 1
orientation for both connector and shroud.
3 Attach the support shroud around the Mictor connector. Use HP
Part Number E5346-44701 support shroud.
4 Connect the high-density adapter cable to the Mictor connector
and then to the logic analyzer.
Tabs on the support shroud lock the high-density adapter cable into
the Mictor connector to provide dependable connections and prevent it
from inadvertently being disconnected. They also protect the flexible
end of the adapter from being bent and damaged.
Reference
• Refer to HP publication number 5962-8620E Minimizing
Intrusion Effects when Probing with a Logic Analyzer for
help on the terminations when using the HP E5351A cable.
• Use the illustrations on the following pages to plan and layout
your target system.

Pin 1 and pin 3. Do not use these pins.
Pins 5, 7, 9, ... 37. These pins are even numbered logic probe inputs.
CLKe is the clock probe input used in state analysis. D15e to D0e on
the even side are probe data inputs.
Pin 2 and pin 4. Do not connect these pins. They are SCL and SDA,
which are used by the HP logic analyzer with an emulator or analysis
probe (preprocessor) to program or read target information.
Pins 6, 8, 10, ... 38. These pins are odd numbered logic probe inputs.
CLKo is clock probe input used in state analysis. D15o to D0o on the
odd side are probe data inputs.
Grounds. There are five through-hole connections that are the ground
returns for the 32 data and 2 clock probe inputs. This connection
should be made to the target’s digital ground plane as close to the
target as possible.

Document Warranty
The information contained in this
document is subject to change
without notice.
Hewlett-Packard makes no
warranty of any kind with
regard to this material,
including, but not limited to,
the implied warranties of
merchantability or fitness for
a particular purpose.
Hewlett-Packard shall not be
liable for errors contained herein
or for damages in connection with
the furnishing, performance, or
use of this material.
Safety
This apparatus has been designed
and tested in accordance with
IEC Publication 1010, Safety
Requirements for Measuring
Apparatus, and has been supplied
in a safe condition. This is a
Safety Class I instrument
(provided with terminal for
protective earthing). Before
applying power, verify that the
correct safety precautions are
taken (see the following
warnings). In addition, note the
external markings on the
instrument that are described
under "Safety Symbols."
Warning
• 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.
• Only fuses with the required
rated current, voltage, and
specified type (normal blow, time
delay, etc.) should be used. Do
not use repaired fuses or shortcircuited fuseholders. To do so
could cause a shock of fire hazard.
• Service instructions are for
trained service personnel. To
avoid dangerous electric shock,
do not perform any service unless
qualified to do so. Do not attempt
internal service or adjustment
unless another person, capable of
rendering first aid and
resuscitation, is present.
• If you energize this instrument
by an auto transformer (for
voltage reduction), make sure the
common terminal is connected to
the earth terminal of the power
source.
• Whenever it is likely that the
ground protection is impaired,
you must make the instrument
inoperative and secure it against
any unintended operation.
• Do not operate the instrument
in the presence of flammable
gasses or fumes. Operation of any
electrical instrument in such an
environment constitutes a definite
safety hazard.
• Do not install substitute parts or
perform any unauthorized
modification to the instrument.
• Capacitors inside the
instrument may retain a charge
even if the instrument is
disconnected from its source of
supply.
