General Safety Summary
Review the following safety precautions to avoid injury and prevent damage to
this product or any products connected to it. To avoid potential hazards, use this
product only as specified.
Only qualified personnel should perform service procedures.
While using this product, you may need to access other parts of the system. Read
the General Safety Summary in other system manuals for warnings and cautions
related to operating the system.
ToAvoidFireor
Personal Injury
Connect and Disconnect Properly. Connect the probe output to the measurement
instrument before connecting the probe to the circuit under test. Disconnect the
probe input and the probe ground from the circuit under test before disconnecting
the probe from the measurement instrument.
Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings
and markings on the product. Consult the product manual for further ratings
information before making connections to the product.
Connect the ground lead of the probe to earth ground only.
Do not apply a potential to any terminal, including the common terminal, that
exceeds the maximum rating of that terminal.
Do Not Operate Without Covers. Do not operate this product with covers or panels
removed.
Avoid Exposed Circuitry. Do not touch exposed connections and components
when power is present.
Do Not Operate With Suspected Failures. If you suspect there is damage to this
product, have it inspected by qualified service personnel.
Do Not Operate in Wet/Damp Conditions.
Do Not Operate in an Explosive Atmosphere.

Operating Basics
The P5050 is a compact, high impedance, passive probe designed for use with
Tektronix TDS5000 Series Digital Phosphor Oscilloscopes. The P5050 has a
1.3 meter cable and is fully compatible with the Tektronix family of compact
size (3.5 millimeter) probe accessories. The Replaceable Parts list beginning on
page 10 identifies the standard and optional accessories for the P5050 probe.

Operating Basics
Probe Compensation
Due to variations in oscilloscope input characteristics, you may need to adjust
the low-frequency compensation of the probe when you move it from one
oscilloscope to another. If a 1 kHz calibrated square wave displayed at
1 ms/division shows significant differences between the leading and trailing
edges, perform the following steps to optimize low-frequency compensation:
1. Connect the probe to the calibration signal on the oscilloscope front panel.
2. Press AUTOSET or otherwise adjust your oscilloscope to display a
meaningful waveform.
3. Adjust the trimmer in the probe (accessible through the compensation box)
until you see a square wave with perfectly flat top on the display. See
Figure 3 on page 3.
WARNING. To avoid damaging the trimmer, use the Philips head adjustment tool
supplied with your P5050 probe. Adjustment tools from some probe models may
not be compatible with the P5050 probe. See Figure 2 below.

Figure 3: Probe compensation waveforms
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. Refer to Figure 4.

Cleaning
To remove accumulated dirt from the probe exterior, use a soft cloth dampened
with a mild detergent and water solution, or use isopropyl alcohol. Do not use
solvents such as benzene, toluene, xylene, or acetone. Avoid abrasive cleaners.

Guard This feature keeps fingers away from the probe tip for
protection against electric shock.

Retractable hook tip Connects the probe tip to wires and component leads for
hands-free measurement.
NOTE. For a solid connection, firmly push and twist the hook
tip onto the probe tip before using.
Adjustment tool This Philips head tool is used to adjust probe compensation.
Access the adjustment through the opening in the compensation box.
CAUTION. To avoid damage to the trimmer, use only this
adjustment tool for adjusting probe compensation.
Color marker bands Color codes the probe to the oscilloscope input when more
than one probe is in use. Clip one band around the strain relief
of the probe head and the matching band on the strain relief of
probe output.
