TriMode Probe Calibration
After you perform a functional check of the probe, run a probe calibration routine. We recommend that you repeat the prob e
calibration for all four of the TriMode settings, and do this on each channel that you use.
The probe calibration operation minimizes measurement errors by optimizing the gain and offset of both probe attenuation settings
on each channel. Individual calibration constants are stored for each calibrated TriMode setting, on e ach probe, on each channel.
CAUTION. To avoid ESD damage to the probe, always use an antistatic wrist strap (provided with your probe), and work at
a static-controlled workstation when you handle the probe.
You can use the equipment s hown in the Functional Check to perform the probe calibration. (See Table 2 on page 10.)

Basic Operation
Basic Operation
This section includes more information about using t he probe controls on the control box and procedures for connecting the
probe to your circuit.
Attenuation and Input Mode Settings
Atten Selection
The ATTEN button toggles the probe between the two nominal attenuation settings of 5X and 12.5X. The choice of attenuation
setting is a tradeoff between probe dynamic range and noise. The probe dynamic range represents th e operating range over which
the probe is linear to within some specified percentage, such as ±1%. The probe noise is usually specified as a noise spectral
density and is significant because of the wide probe bandwidth. The 5X attenuation setting provides the lowest noise performance.
The 12.5X attenuation setting provides the largest dynamic range. The actual probe attenuation factor is automatically accounted
for by the attached oscilloscope using the intelligent TekConnect probe interface. The attached oscilloscope also indicates
the probe dynamic range with momentarily-displayed arrows when the vertical channel controls a re changed at larger vertical
scale factor settings.
The usual choice for attenuation setting should be 5X, if the measured signal fits within the specified dynamic range, since that
provides the best noise performance. The probe Offset control can also be used with some signals to compensate for a DC bias
and bring the displayed signal within the specified dynamic range. Although it is possible to measure signals that e xceed the
dynamic range of the probe, the measured signal performance becomes increasingly non-linear and eventually reaches a limiting
level. Although probe signal limiting does not damage the prob e (as long as the maximum input voltage is not exceeded), the
measured response no longer accurately represents the input signal.
20 P7504 & P7506 TriMode Probes Quick Start User Manual
Basic Operation
Input Mode Selection
The Input Mode button toggles the internal probe input selector switches between the four input mode selections. This TriMode
feature allows full characterization of a differential signal from a single soldered connection.
A-B Mode. The A-B Mode is used for making differential signal measurements and represents the traditional differential probe
functionality. Since the A-B Mode measures the difference between the A and B input signals, it eliminates any common mode
voltage, such as a DC bias common to both inputs, within the CMRR performance capability of the probe. For P7500 probe tips that
do not provide a TriMode ground reference, such as the P75PDPM handheld probing module, the A-B Mode is the only useful
mode for making low noise measurements. In fact, some oscilloscope models only allow the A-B Mode to be selected when the
connected tip does not include a ground reference. The A-B Mode can also be used for making single-ended measurements with
the P75PDPM probe tip by connecting the B input to the local circuit ground.
A-GND Mode. The A-GND mode is used for making probe A input single-ended measurements with TriMode probe tips such
as the Micro-Coax solder tip. The Micro-Coax solder tip includes a solder connection for the local circuit ground. In the A-GND
Mode the P7500 probe input switch is configured to measure the A input relative to this local circuit ground reference. The A input
signal measurement in A-GND Mode is designed for minimal coupling from any signal present on the B input within the A input
isolation performance of the probe.
The A-GND Mode is not recommended for measurement use with the P75PDPM probe tip because of the lack of a local circuit
ground connection (and some oscilloscope models do not allow the A-GND Mode to be selected with the P75PDPM).
P7504 & P75 06 TriMode Probes Quick Start User Manual 21
Basic Operation
B-GND Mode. The B-GND mode is used for making probe B input single-ended measurements with TriMode probe tips su ch
as the Micro-Coax solder tip. The Micro-Coax solder tip includes a solder connection for the local circuit ground. In the B-GND
Mode the P 7500 probe input switch is configured to measure the B input relative to this local circuit ground reference. The B input
signal measurement in B-GND Mode is designed for minimal coupling from any signal present on the A input within the B input
isolation performance of the probe.
Like the A-GND Mode, the B-GND Mode is also not recommended for measurement use with the P75PDPM probe tip because
of the lack of a local circuit ground connection.
(A+B)/2 Mode. The (A+B)/2 Mode is used fo r making common mo de mea surements on a differential signal and represents a
new probe feature th at previously could only be made using oscilloscope math on multiple channels. For a differential signal, the
common mode measurement indicates the DC bias level and also shows the degree of asymmetry between the A and B inputs.
Since the (A+B)/2 Mode measures the average between the A and B input signals, it eliminates any complementary differential
signal voltage, within the DMRR performance capability of the probe.
22 P7504 & P7506 TriMode Probes Quick Start User Manual
ConnectingtoaCircuitBoard
The P7504 and P7506 TriMode probes use a two-part interconnect system to make connections to your circuit. The Socket Cable

TriMode High Temp Solder Tip
The High Temp Solder tip is designed for
use with the optional Socket Cable XL, but is
usable with the standard Socket Cable. This
tip enables you to take measurements on your
circuit over a wide tem perature range: –55 °C
to +150 °C (-67 °F to 302 °F).
The resistor leads on the tip pass the two
complementary signals from your circuit,
through the Socket Cable, to the TriMode
probe. The tip resistors can tolerate several
solder cycles and can be replaced when
necessary.
NOTE. For best signal fidelity, you must trim
the resistor leads to the shortest length possible
to reach your test points. Long leads degrade
the quality of the measured signal.
This tip provides full TriMode capabilities when
you u se the soldered-ground connection on the
tip board.
Two High Temp Solder tips are included with
the probe.

Basic Operation
Notes on Using the Tips.
Use the following precautions when you solder the tips:
CAUTION. To prevent damage to the circuit board or circuit board connections due to accidental movement of the probe and
soldered leads, we recommend that you secure the tip to the circuit board using the adhesive tip tape provided in your accessory
kit. You can also use other materials such as Kapton tape or hot glue.
To avoid damage to the tip or the circuit under test, avoid applying excessive heat from the soldering iron. Use a low-wattage,
temperature-controlled soldering iron and appropriately sized soldering iron tip.
Use a low-wattage, temperature-controlled soldering iron and a small mass soldering iron tip. The soldering iron temperature
should be set as low as possible, while still providing a reliable s older joint.
Use SAC305 solder (included with th e wire replacement kit) to attach the tip wires to the circuit under test.
The attachment wires should be bent symmetrically to vary the interconnect spacing. Use care when you solder a tip to a circuit
under test to avoid inadvertently desoldering either the attachment wires or the damping resistor.
For optimum performance and signal integrity, keep the lead length between the DUT (Device Under Test) and the tip as
short as possible, and the lead lengths the same length.

Error Conditions
LEDs Do Not Remain Lit
If none of th e Range or TriMode LEDs remain lit after you connect the prob e, a probe/oscilloscope interface fault exists. Perform
the following steps until you clear the fault or isolate the problem:
Disconnect and reconnect the probe to restart the power-on diagnostic sequence.
Connect the probe to a different channel on the oscilloscope.
Disconnect the probe from the oscilloscope, power-cycle the oscilloscope, and then reconnect the probe.
Connect the probe to a different oscilloscope.
If the sympto m s remain (they follow the probe), then the probe is defective and must be returned to Tektronix for repair.
LEDs Flash On and Off
If all of the Range or TriMode LEDs flash on and off repeatedly after you connect the probe, an internal prob e diagnostic fault

Input Mode Selection
If you cannot select an Input Mode other than A-B and you are using a TriMode tip that does not provide a circuit ground connection
(such as the P75PDPM), this is normal operation. The other input modes refer to circuit ground and are only valid when a
TriMode tip that provides a circuit ground connection is selected.
If you are using a TriMode tip that provides a circuit ground connection (such as the TriMode High Temp Solder Tip) and you cannot
select an Input Mode other than A-B, check the Probe Setup screen on the oscilloscope. An incorrect Probe Tip might be selected.

Handling the Probe
This probe is a precision high-frequency device; exercise care when you use and store the probe. The probe and cable are
susceptible to damage caused by careless use. Always handle the probe at the control box and probe body to avoid undue physical
strain to the probe cable, such as kinking, excessive bending, or pulling. Visible dents in the cable will increase signal aberrations.
CAUTION. To prevent da mage to the probe, always use an antistatic wrist strap connected to a static-controlled workstation when
you handle the probe. The probe input contains electronic components that can be damaged by contact with high voltages,
including static discharge.
Observe the following precautions when using the probe. Do not do any of the following:
Drop the probe or subject it to physical shock
Subject the probe to a dverse weather conditions
Kink or fold the probe cable tighter than a 2 in ch radius
Solder the tips with excessive heat or duration
Injure yourself with the sharp tips

Cleaning the Probe
CAUTION. To prevent damage to the probe, do not expose it to sprays, liquids, or solvents. Avoid getting moisture inside
the probe during exterior cleaning.
Do not use chemical cleaning agents; they may damage the probe. Avoid using chemicals that contain benzine, benzene,
toluene, xylene, acetone, or similar solvents.
Clean the exterior surfaces of the probe with a dry, lint-free cloth or a soft-bristle brush. If dirt remains, use a soft cloth or swab
dampened with a 75% isopropyl alcohol solution and rinse with deionized water. A swab is useful to clean narrow spaces on the
probe; use only enough solution to dampen the swab or cloth. Do not use abrasive compounds on any part of the probe.
