P6209 4 GHz Probe Instruction Manual

Configuration
The P6209 provides the oscilloscope with the probe model number,
serial number, and attenuation factor. When connected to the
oscilloscope, the display readouts are corrected for the probe
attenuation factor.
The probe offset control is controlled by the oscilloscope.
CAUTION. To prevent damage to your probe, do not apply a voltage
outside the Maximum Input Voltage rating. See Specifications on
page 21.

To prevent electrostatic damage to the instrument and sampling
modules, follow the precautions described in the manuals
accompanying your instrument.
Always use a wrist strap (provided with your probe) when handling
the probe and sampling modules, and when making signal
connections.

Probe Offset
The purpose of the offset capability is to permit the input signal to be
positioned in the center of the dynamic range of the probe amplifier,
to obtain the best transient response. Using the offset to cancel DC
signal components enables optimal probe performance. See Figure 1
on page 10 for more information.
NOTE. If the offset is not correctly positioned, clipping or distortion
of the displayed signal may occur. See your oscilloscope manual for
specific instructions on its operation and offset control.

P6209 4 GHz Probe Instruction Manual

Configuration

To set the probe offset, follow these steps:
1. Set the oscilloscope vertical scale to the least sensitive V/div
setting (500 mV/div on the CSA/TDS8000).
2. Attach the probe to the circuit.
3. Adjust the probe offset to bring the trace onto the oscilloscope
screen.
4. Change the volts/division setting to the desired range, adjusting
the offset to keep the trace on screen.
NOTE. The P6209 has a ±5.0 V offset range. The linear operating
range is ±2.00 V. See Figure 1. Also, see page 13 for more information.

Functional Check

4. Set the offset to 1V, the vertical scale to 500 mV/div, and the
horizontal scale to 2 s/div.
5. The observed waveform should be a 200 kHz square wave with
an amplitude of approximately 2 V (the clock output is
unterminated), and have an offset of approximately 1 V.
If the probe does not pass this functional check, go to Troubleshooting on page 51.

P6209 4 GHz Probe Instruction Manual

Operating Basics
Please follow these operating guidelines to get optimum performance
from your P6209 probe.

Handling the Probe
Exercise care when using and storing the P6209 probe. The probe
and cable are susceptible to damage caused by careless use. Always
handle the probe using the compensation box and probe head,
avoiding undue physical strain to the probe cable, such as kinking,
excessive bending, or pulling. Visible dents in the cable will increase
signal aberrations. Do not drop the probe or subject it to physical
shock. Damage to the probe may result.
CAUTION. To prevent damage to your probe, do not apply a voltage
outside the Maximum Nondestructive Input Voltage for the probe.

Always use a wrist strap (provided with your probe) when
handling the probe and sampling modules, and when making
signal connections.

Maximum Nondestructive Input Voltage
Applying voltages above the P6209 design limits may damage the
probe tip amplifier. Please refer to Specifications on page 21 for the
maximum operating voltage and frequency derating information.

Input Linear Dynamic Range
The probe head amplifier used by the P6209 has a limited linear
operating range. To keep the input linearity error less than 0.1%, you
must limit the apparent signal input voltage to ±1.75 V.

P6209 4 GHz Probe Instruction Manual

13

Operating Basics

Use the DC offset adjustment to maintain the probe within its
dynamic range. The nominal offset adjustment range of the P6209 is
±5.0 VDC. For example: to offset a +2 VDC level in a circuit, set the
offset to +2 V.
NOTE. The probe can tolerate input voltages of ±30 V (≤5 minutes)
without damage; however, the linearity error specification does not
apply to input voltages outside the linear dynamic range of the
probe. See Figure 1 on page 10.

Ground Lead Length
When you are probing a circuit, you should always use as short a
ground lead as possible between the probe head and circuit ground.
The series inductance added by the probe tip and ground lead can
result in a resonant circuit; this circuit may cause parasitic ringing
within the bandwidth of your oscilloscope. When you touch your
probe tip to a circuit element, you are introducing a new resistance,
capacitance, and inductance into the circuit. Refer to Figure 3.

Figure 3: Ground lead equivalent circuit
Ringing and rise time degradation can be masked if the frequency
content of the signal degradation is beyond the bandwidth of the
oscilloscope.

14

P6209 4 GHz Probe Instruction Manual

Operating Basics

You can determine if ground lead effects may be a problem in your
application if you know the self-inductance (L) and capacitance (C)
of your probe and ground lead. Calculate the approximate resonant
frequency (f0) at which this parasitic circuit will resonate with the
following formula:
f0 =

1
2π LC

The preceding equation shows that reducing the ground lead
inductance will raise the resonant frequency. If your measurements
are affected by ringing, your goal is to lower the inductance of your
ground path until the resulting resonant frequency is well above the
frequency of your measurements.
The low-inductance ground contacts described in Accessories can
help you reduce the effects of ground lead inductance on your
measurements.

Helpful Hints
Follow these helpful hints to make probing easier and noise free.

Low-inductance Grounding
Placing a ground plane on top of a package being probed can
minimize ground lead length and inductance. See Figure 4.

Figure 4: Low-inductance grounding
Attach a small piece of copper clad on top of the package and
connect it to the package ground connection. Use the low-inductance
ground lead provided with the P6209 to keep the ground lead length
as short as possible.

Helpful Hints

This method is very useful when making many measurements on the
same package. Using a ground plane on the package makes probing
the package easier and avoids adding unnecessary ground lead length
and distortion.

SureFoot Grounding
If you cannot use the recommended low-inductance grounding
method, you may ground the probe to the package under test using a
SureFoot adapter. Refer to Figure 5.

Figure 5: Using a SureFoot adapter for grounding
Use a SureFoot adapter at the end of a short ground lead to connect
directly to the package ground. This method is preferred over using
an adjacent circuit ground because it is the shortest ground path
possible.

Probe Tip Test Points
You can solder the push-in probe tip or a 0.025 square pin to a circuit
to be used as a temporary test point. See Figure 6.
Solder the tip onto a lead or pin with a low-power soldering iron.
Press the probe head onto the tip to make a measurement, and then
pull the probe head off when you are done.
The probe tip may be removed and reused by desoldering it from the
circuit and soldering it into another circuit in the future.

Solder

Figure 6: Using a probe tip as a test point
NOTE. Do not use pieces of solid-core copper wire as test points. If
the wire breaks off in the probe tip socket, it may be impossible to
remove the wire, and it will prevent insertion of other accessory tips.

Calculating DC Voltage Measurement Accuracy:
DC Voltage Measurement Accuracy (referred to input)
= [2% of input + (2% of offset) + 37.5 mV + 3.5 mV]
where:
gain error = 2% of input voltage (relative to offset voltage)
offset gain error = 2% of effective offset at probe tip
output zero = 37.5 mV effective at probe tip (worst case, but
does not include any oscilloscope offset control voltage error)
linearity error1 = 0.1% of 1.75 V (3.5 V full scale)=3.5 mV
High Error Example. To determine the maximum specified DC error
when measuring a PECL logic high of approximately 4.1 V with
probe offset set to 3.7 V:
(2% of input voltage = 8 mV, +
2% of offset voltage = 74 mV, +
output zero = 37.5 mV (worst case value), +
linearity error = 3.5 mV)
= 123 mV
Low Error Example. To determine the maximum specified DC error
when measuring a LVDS low of approximately 1.0 V without any
probe offset (0 V):
(2% of input voltage = 20 mV, +
2% of offset voltage = 0 mV, +
output zero = 5 mV (effective offset at probe tip due to typical
offset value of 1 mV at probe output), +
linearity error = 3.5 mV)
= 28.5 mV

The linearity specification is rated with a segmented range (see page 22).
The linearity error is higher at the extreme ends of the dynamic range.

Theory of Operation

Probe Head and Cable Assembly
The probe head assembly contains an active amplifier circuit that
buffers and amplifies the input signal. The amplifier receives power
and an offset level from the compensation box assembly via the
cable assembly.
All signal amplification and buffering is performed in the probe head
assembly. No further amplification takes place in the compensation
box.

Compensation Box
The compensation box contains the following circuits:
H Offset amplifier
H Probe identification EEPROM
H TEKPROBE SMA interface
H VCC, +7 V linear regulator
Offset Amplifier
The offset amplifier is used to offset the input signal DC component
so that it stays at the optimal point of the probe linear dynamic
range. For more information on the linear dynamic range characteristic, refer to Input Linear Dynamic Range on page 13.
The offset amplifier receives offset information as a ±1 VDC voltage
from the oscilloscope. The amplfier then amplifies it to match the
probe characteristics and applies it to the probe head circuit.
The offset amplifier has two adjustments: offset zero and offset scale.
These adjustments rarely need attention; however, detailed
adjustment instructions are in the Adjustment section on page 43.
Probe Identification EEPROM
The probe identification EEPROM is used to configure the
oscilloscope to the probe. The EEPROM receives a clock input from

30

P6209 4 GHz Probe Instruction Manual

Theory of Operation

the oscilloscope, and information about the probe is passed to the
oscilloscope.
TEKPROBE SMA Interface
The TEKPROBE SMA interface provides a communication path
between the probe and the oscilloscope. Contact pins provide power,
signal, offset, and data transfer for the probe identification
EEPROM.
Figure 11 shows the probe interface pin functions. Refer to your
oscilloscope service documentation for more detailed specifications.

Performance Verification

NOTE. The P6209 probe is guaranteed to have less than 7.5 mV
offset. However, the CSA/TDS8000 and TDS 820 will have some
residual voltage remaining when set to 0.00 V offset that will appear
in this test as additional offset at the probe output.

DC Attenuation Accuracy
Use this procedure to verify the probe DC attenuation accuracy.
1. Set the oscilloscope trigger to internal clock.
2. Set the oscilloscope channel vertical offset to 0.00 V.
3. Set the multimeter to read DC volts.
4. Connect the probe tip and ground to the DC calibrator output of
the CSA/TDS8000, using the Y-lead adapter, KlipChips and SMA
adapter jack.
If the probe is being used with a TDS 820 oscilloscope, a separate
DC power supply is needed to provide the stimulus. In this case,
connect the probe to the power supply using the Y-lead adapter
and KlipChips.
Record the results of steps 5 through 11 separately. Use the results to
calculate the DC accuracy of the probe in step 12.
5. Set the DC calibration output of the CSA/TDS8000 (or external
power supply if using a TDS 820), to +1.000 V. Use the
multimeter to verify the DC voltage is as close to +1.000 V as
possible. Record this measurement as Vmax.

the benefit of the latest circuit improvements. Therefore, when
ordering parts, it is important to include the following information in
your order:
H Part number
H Instrument type or model number

If a part you order has been replaced with a different or improved
part, your local Tektronix service center or representative will
contact you concerning any change in the part number.

Using the Replaceable Parts List
The tabular information in the Replaceable Parts List is arranged for
quick retrieval. Understanding the structure and features of the list
will help you find the information you need for ordering replacement
parts.
Item Names
In the Replaceable Parts List, an Item Name is separated from the
description by a colon (:). Because of space limitations, an Item
Name may sometimes appear as incomplete. For further Item Name
identification, U.S. Federal Cataloging Handbook H6-1 can be used
where possible.
Indentation System
This parts list is indented to show the relationship between items.
The following example is of the indentation system used in the
Description column:
1 2 3 4 5
Name & Description
Assembly and/or Component
Attaching parts for Assembly and/or Component
(END ATTACHING PARTS)
Detail Part of Assembly and/or Component
Attaching parts for Detail Part
(END ATTACHING PARTS)
Parts of Detail Part
Attaching parts for Parts of Detail Part
(END ATTACHING PARTS)

Attaching parts always appear at the same indentation as the item it
mounts, while the detail parts are indented to the right. Indented
items are part of, and included with, the next higher indentation.
Attaching parts must be purchased separately, unless otherwise
specified.
