Installation
Installation
Before you connect the probe to your instrument, read the Overview below to understand the sequence of events necessary to
properly install the probe and adapters.
CAUTION. To avoid ESD damage to the probe, always use an antistatic wrist strap (provided with your probe), and work at
a static-approved workstation when you handle the probe.
Overview
1. Connect the probe to the host instrument.
If it is the first time the probe has been connected to the oscilloscope, the oscilloscope will download the S-parameters stored in
the probe. Once the oscilloscope has stored the S-paramete rs for the probe, it doesn’t matter which channel the probe is
plugged into. The stored S-parameters will be available for any channel the probe is moved to.
2. Connect the probe t ip to the TekFlex connector on the probe.
When a tip is inserted into the probe for the first time, the oscilloscope will download the S-parameter data stored in the tip.
3. The p
4. Open the Calibration menu (found in the Vertical menu).
5. Perform the DC probe calibration procedure using the DC probe cal fixture that ships standard with each probe. (See page 18,

Connect to the host instrument
NOTE. Your TekConnect instrument may
require a firmware upgrade to support full
functionality of the P7700 Series probes.
Before you connect the probe, check the
version requirements. (See page 74, Host
instrument firmware.)
1. Slide the probe into the TekConnect
receptacle. The probe clicks into place
when fully engaged.
2. Optional. Turn the thumbscrew clockwise
(finger-tight only) to secure the probe to
the instrument.
Disconnect
3. To disconnect, turn the thumbscrew
counter-clockwise.
4. Press the latch release button and pu ll the
probe away from the instrument.
Installation
P7700 Series TriMode Probes User Manual 5
Installation
Probe and probe tip power-on
After the con nection to the oscilloscope is
made:
1. The probe briefly turns on all LEDs during
a self-test, and then the A – B Input Mode
LED remains on. If a probe tip is attached,
an LED on the tip also turns on when
properly attached to the probe.
2. The probe transfe rs data from the probe
and tip to the host instrument, and a
message displays on the instrument as the
transfer occurs.
The data transfer takes a few minutes,
and is only don e when the host instrument
discovers a new probe or new probe
tip. The data transfer only occurs on
instruments that are fully compatible with
the probe.
3. After the data transfer is done, the probe is ready for a fun c tional check and calibration. (See page 11, Functional check.)
NOTE. If the probe’s warning light remains on, the power-on self-test likely failed.
(See page 76, Error conditions.)

Connect P7700 accessories to the TekFlex connector
All of the P7700 accessories mate with the new TekFlex (zero insertion force) connector. This connector provides an easy
connection with one handed operation for attaching to the P7700 series accessories. T he following procedures show the steps for
connecting probe tips to the TekFlex conne ctor; the procedures for connecting to other accessories are similar.
Connect the tip to the probe TekFlex connector as follows:
1. Pinch the TekFlex connector to open the
jaws.
2. Orient the tip with the probe head (notch to
the left) and slide the tip connector into the
TekFlex connector.
A green LED will light up when the tip is
inserted. The LED is the first indication that
the tip is powered and is inserted. You also
need to confirm that the connector p in s
on the TekFlex connector fit through the
alignment holes on the tip.
3. Once the tip is fully inserted, release the
pinch and the TekFlex connector closes.
When closed and properly seated, the top
of connector will be flush with the probe tip
housing.

NOTE. You can also change the Input Mode in the oscillosco pe Probe Setup screen.
Press the Input Mode button to select one of
the four TriMode measurements. The modes
cycle in the following sequence:

The Warning LED glows amber under the
following conditions:

Probe tip over-temperature detected
The input voltage on either the A or B input
exceeds the allowable limit
The Warning LED clears when the condition
causing the warning is removed. A notifier
message of a probe warning condition can also
be seen on the oscilloscope.
CAUTION. Do not exceed the input voltage limits of the probe and probe tips. The probe or oscilloscope circuits may be damaged
if the limits are exceeded. Make sure that you understand and work within the limits of the pro be and probe tips.

Functional check and calibration
After you connect the probe to the oscilloscope, you can perform a functional check using either the optional deskew fixture
designed for the probe or the optional P77C292MM Adapter.
CAUTION. To avoid ESD damage to the probe, always use an antistatic wrist strap (provided with your probe), and work at
a static-approved workstation when you handle the probe.
Functional check
This procedure checks the four TriMode settings on the probe, using the FAST EDGE signal from the front panel of the oscilloscope.
It verifies the signal path o f both the probe A and B input signals and their combination in the four TriMode settings. The P7700
Series Probe deskew fixture is used to connect the FAST EDGE signal to the probe tip input. (See Table 2.) Alternately, the P7700
Series probe with the optional coaxial input adapter can connect directly to the FAST EDGE signal. (See Table 3 on page 12.)

Test setup with the P77DESKEW
Fixture
1. Connect the probe to any channel (1-4)
of the oscilloscope (connection to CH4 is
shown). Set the oscilloscope to display the
connected channel.
2. Connect the USB cable assembly supplied
with the P77DESKEW fixture between the
USB connector on the fixture board and a
USB connector on the host oscilloscope.
Several white LEDs under the fixture Port1
and Port2 probe tip clamps will light up
when the fixtu re is attached to USB power.
3. Connect an SMA cable from the FAST
EDGE output connector on the oscilloscope
to the A input of the Probe Deskew Fixture.
4. Connect a P7700 Series probe tip to either the Port1 or Port2 on the P77DESKEW fixture. If a TekFlex solder-in tip is used
to make this connection, its tip input should be inserted into the plastic clamp of the deskew fixture port. This is done by
compressing the spring-loaded clamp, inserting the probe tip input into the clamp, and then releasing the clamp so that it
locks the connection.
P7700 Series TriMode Probes User Manual 13
Functional check and calibration
An additional set of green LEDs will light up under the probe tip clamp when the solder-down probe tip is properly inserted
into the clamp.
Finally, connect the TekFlex connector at the end of the probe main cable to the probe tip inserted into the deskew fixture port.
An LED on the probe tip will also light up when the tip is properly inserted into the TekFlex connector of the probe.
5. If a P77BRWSR tip is used instead of a solder-down tip to make connection to the Deskew Fixture, th e TekFlex connector of the
probe should first be connected to the P77BRWSR tip. The P77BRWSR tip inputs must t hen be pressed into place against the
A and B signal traces on the P77DESKEW fixture board edge, located between the Port1 and Port2 clamps. Either of the two
sets of A and B signal trace connection patterns located on the P77DESKEW fixture board edge may be used.

Functional check and calibration
Test setup with the P77C292MM
adapter
1. Connect the probe to any channel (1-4)
of the oscilloscope (connection to CH4 is
shown). Set the oscilloscope to display the
connected channel. Connect the probe to
the P77C292MM adapter.
2. Connect the A cable from the P77C292MM
adapter to the FAST E DGE output
connector on the oscilloscope. Leave the
B cable disconnected for now.
Test procedure
1. Set the prob e Input Mode to A-B.
2. Adjust the oscilloscope to display a stable waveform (or press the Autoset button). The FAST EDGE signal is a 1 KHz square
wave. The amplitude of the FAST EDGE signal is attenuated b y 2X, compared to a single path termination, due to the
power splitter built into the P77DESKEW fixture.
P7700 Series TriMode Probes User Manual 15
Functional check and calibration
3. When you see a stable square waveform, check the amplitude (use the horizontal cursors). The atten uated amplitude displayed
for a DPO70000 oscilloscope FAST EDGE signal routed throu gh the Deskew Fixture should be about 100 mVpp.
4. Cycle the Input Mode button through the
remaining selections and compare the
displayed waveforms to the waveform
measured in the setup steps.

A-GND (same amplitude and polarity as
preivously measured)
