You can only connect the probe to a target system that has the
mating probe compression footprint designed in and the probe
retention assembly installed. (See Dimensions and Installingthe Probe Retention Assembly.) A lways clean the footprint
contacts before you connect the probe.

Installing the Probe Retention Assembly
The probe retention assembly provides a housing around the
connector footprint to secure the probe to the PCB. To install the
probe retention assembly on the circuit board, do the following:
1.If your PCB has multiple connector footprints, locate the
correct one.
2.Align the retention assembly over the footprint so that the
keying pin on the retention assembly lines up with the
keying pin hole on the footprint.

Product Description
The P6750 logic probe is a 17-channel, high-density
connectorless probe with D-Max probing technology. It
connects the 16 digital channels on Tektronix MSO70000
Series oscilloscopes to digital buses and signals on your target
system. A clock/qualifier (QC) input is also provided.
The cLGA contact (compression Land Grid Array) on the probe
mates to a PCB footprint that you design into your system
circuit board. The probe is secured with two thumbscrew s to a
retention assembly that you solder onto the circuit board.
2.Start both screws in the retention assembly, and tighte
them evenly to ensure that the probe approaches and mates
squarely to the PCB. The probe is completely fastened to
the PCB w hen the screws stop in the assembly.
Setting Up the Probe
From the Digital menu, select Digital Setup to set and view the
following parameters of each digital channel:
Threshold voltage and vertical position
Signal height
Channel label
The default settings are 1.4 V t hresholds with digital channel
number labels.
From the Digital menu, select Bus Setup to set and view bus
characteristics such as:
Clock source
Bus type (Serial or Parallel)
Bus width
Display format (Hex, Binary, or ASCII symbols)
Parallel bus setup information is resident on MSO70000 Series
oscilloscopes. However, for other buses such as I2C, you must
have the a ppropriate option. See your oscilloscope manual or
product data sheet for nomenclature and ordering details.
(set once for all 16 channels)

3.Insert the retention assembly into the holes in the footprint
on the PCB.
NOTE. The following two steps are important to ensure that
the retention assembly is correctly m ounted and that the probe
makes proper contact with the PCB.
4.Hold the retention assembly so that it is firmly flush with
the surface of the PCB, and the four anchoring posts
extend through the circuit board to the opposite side.
5.Using a pair of needle-nose pliers, hold one of the posts.
Using the circuit board hole as a fulcrum, bend the post
outwardsothatitisflush with the PCB surface, anchoring
the assembly to the PCB. Bend the other three posts in
the same manner.
CAUTION. After you insert the wires in the board, it is
important to bend the anchoring posts out to avoid solder
creep.
Connecting the Probe to the Oscilloscope
Connect the probe as shown in the illustration below.
1.Insert the probe label-side up into the receptacle.
2.To remove the probe, push the probe in, press the button,
ull out the probe.

Functional Che ck
Logic activity immediately displays on all connected, active
channels. If you do not see an active signal:
1.Press Trigger.
2.Select Edge for trigger type.
3.Select the channel that you are setting up as the source.
If you still do not see a n active signal, use an analog probe or the
iCapture analog mu
x to verify circuit activity at the test point.
Typical Application
1.Use the P6750 probe to view digital signals on a data bus.
2.Use iCapture or analog probes, such as the P7508 TriMode
probe to view analog waveform information.
6.Solder the anchoring posts to the PCB.

Safety Terms and Symbols in This Manual.
These terms may appear in this manual:
WARNING. Warning statements identify conditions or
practices that could result in injury or loss of life.
CAUTION. Caution statements identify conditions or
practices that could result in damage to this product or
other property.
NOTE. Y
ou should use immersion gold surface finish for the
best performance. Also, let the probe attachment holes float
in unconnected to a ground plane. This prevents
or rema
overheating the ground plane and promotes quicker soldering
etention posts to your PCB.
of the r
Use via-in-pad to route signals to the pads on the circuit board.
This allows you to minimize the stub length of the signals
on your board, thus providing the smallest intrusion to your
signals. It also enables you to minimize the board area that is
used for the probe footprint and maintain the best electrical
performance of your design.
2.Align the new contact clip with the probe head and gently
snap it into place.
3.Test the probe to confirm that all channels are functional.
