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 a P76xxx adapter to the probe. This step should be done before you connect the probe to the oscilloscope.
2. Connect the probe to the oscilloscope.
3. The probe performs a self test, and then one Input Mod e LED remains lit.
4. The oscilloscope discovers the probe (if this is the first time they are connected), and downloads S-parameter data from the
probe. The oscilloscope then computes the filters. A message displays until the process is complete.
5. The P robe Setup screen displays (if this is a first-time connection).
6. Perform a functional check on th e probe.
7. Use the Probe Setup screen to set the probe parameters as described in the Basic Operation section.

P7600 Series TriMode Probes User Manual 3
Installation
Connect TriMode Adapters to the Probe Body
TriMode adapters are required to complete the connection between the probe and your circuit, and are briefly de scribed below. The
adapters connect the P7600 Series probes to your circuit through 2.92 mm or SMP cables, or through P7500 Series solder tips,
such as the P75PST Performance Solder Tip. The adapter inputs are polarized, with the A input marked in red and the B input
marked in black. The adapters should be connected to the probe before the probe is connected to the instrument.
1. P76CA-292
Use this adapter with high quality,
skew-matched cables that have male
2.92 mm connectors at the probe end. The
other end of the cables can be customized with
connectors that mate to your circuit.
2. P76CA-292C
This adapter includes a pair of skew-matched,
6 inch cables with male 2.92 mm connectors.
3. P76CA-SMP
This adapter includes a pair of skew-matched,
6 inch cables with female SMP connectors.
4. P76TA
Use this adapter with P7500 Series probe
solder tips. (See page 39, Connecting to a
Circuit Board.)
4 P7600 Series TriMode Probes User Manual
Connect th e Adapters
All of the adapters mate to the P7600 Series
probe head through a keyed, multi-pin
connector that transfers the adapter information
to the oscilloscope for automatic identification.
Connect them as follows:
1. Orient the adapter to the probe body with
the A and B inputs on top, as shown.
2. Insert the adapter into the probe head.
3. Attach the adapter to the probe head with
the hex tool included with the probe. Use
the long end of the tool as shown, a nd only
use enough force to ensure a secure fit.
CAUTION. As you tighten the adapter screw,
be careful not to damage the input cables on
adapters with integral cables.
CAUTION. Do not overtighten the adapter
screw. You can damage the connectors if you
apply too much torque to the screw.

Installation
Connect to the Host Instrument
NOTE. Your TekConnect instrument may
require a firmware upgrade to support full
functionality of the P7600 Series probes.
Before you connect the probe, check the
version requirements. (See page 61, Host
Instrument Firmware.)
1. Slide the probe into the TekConnect
receptacle. The probe clicks into place
when fully engaged.
2. 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 pull the
probe away from the instrument.
6 P7600 Series TriMode Probes User Manual
Probe Power-On
After the initial connection to the oscilloscope
is made:
1. The probe briefly lights all LEDs during a
self-test, and then the A – B Input Mode
LED remains lit.
2. The probe transfers data 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 done when the host instrument
discovers a new probe. 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 functional check and calibration.
(See page 11, Functional Check.)

Input Mode Button and LEDs
Press the Input Mode button to select one of
the four TriMode measurements. The modes
cycle in the following sequence:
A – B (for differential signal measurement)
A – GND (for A inp ut single-ended
measurement)
B – GND (for B inp ut single-ended
measurement)
(A+B)/2–GND(forcommonmode
measurement)
NOTE. You can also change the Input Mode
in the oscilloscope Probe Setup screen. (See

Installation
Overload LED
The Overload LED glows amber under the
following conditions when using the P76CA-xxx
adapters:
• the input voltage on either the A or B input
exceeds ±4.5 V
• the termination voltage driver current on
the A or B input exceeds 50 mA
(See page 23, Termination Voltage.)
The Overload LED clears when the input sign al
is removed.
NOTE. The Overload LED may flash briefly
when you ad just the termination voltage levels;
this is normal.
CAUTION. Do not exceed the input voltage limits of the probe and adapters. The probe or oscilloscope circuits may be damaged if
the limits are exceeded. Make sure that you understa nd and work within the limits of the probe and adapters.

Functional Check and Calibration
After you connect the probe to the oscilloscope, perform a functional check using the procedu re below.
Functional Check
This procedure checks the four TriMode settings on th e probe, using the FAST EDGE connection on the front pane l of the
oscilloscope. The A-B (differential mode) is set up and verified first, and then the remaining input modes are checked and
compared to the differential m ode measurement.

Test Setup
1. Connect the probe to any channel (1–4) of
the oscilloscope.
2. Set the oscilloscope to display the channel.
3. Connect one of the probe inputs to the
FAST EDGE output of the oscilloscope,
using the P76CA-292C adapter.
You can also make the connection with one
of the other P76xxx adapters, but you must
use additional equipment. Refer to the
Required Equipment table. (See Table 2
on page 11.)
4. Leave the other probe input open.
5. Set the termination and offset voltages to
0 volts in the Probe Setup screen. (From
the oscilloscope menu, select Vertical and
then select Probe Cal.)

Test Procedure
6. Set the probe Input Mode to A–B.
7. Adjust the oscilloscope to trigger on and
display a stable waveform (or press the
Autoset button).
NOTE. If you do not see a waveform, check
the connection at the probe body. (See page 4,
Connect TriMode Adapters to the Probe Body.)
8. When you see a stable square wave,
check the amplitude. (Use the horizontal
cursors.) Signal output levels for some
oscilloscope models are listed below.

9. Cycle the Input Mode button through the
remaining selections and compare the
displayed waveforms to the waveform that
you measured in step 8.
A – B (the waveform from step 8)
A – GND (same amplitude and polarity
as measured in step 8)
B – GND (the B input is grounded; no
signal is measured)
(A+B)/2 – G ND (half-amplitude, but the
same polarity a s measured in step 8)
10. Repeat steps 3 through 9 for the other
probe input. Note that with the FAST
EDGE signal now applied to the B input
and with the A input open, the polarity of
the A–B waveform is inverted.
