Tektronix P6139B User manual

Revision A
500 MHz 10X Probes
The P6139B & P5050B probes are high impedance,
passive probes that are designed for use with Tektronix
ground-referenced oscilloscopes, including the
DPO/MSO/TDS 3000/4000/5000/7000 series oscilloscopes.
Both probes have a bandwidth of >500 MHz and 10X
attenuation. The P6139B probe has a compensation range
of 8 to 18 pF, while the P5050B probe has a compensation
range of 15 to 22 pF.
Connecting the Probe to the Oscilloscope
Connect the probe to the oscilloscope as shown below.
Compensating the Probe
Due to variations in oscilloscope input characteristics,
the low-frequency compensation of the probe may need
adjustment after moving the probe from one oscilloscope
channel 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 oscilloscope channel that you
plan to use for your measurements.
2. Connect the probe to the probe compensation output
terminals on the oscilloscope front panel.
WARNING. To avoid electric shock, only connect to the
Probe Comp signal on the oscilloscope when making
this adjustment.
To avoid electric shock, only use the insulated adjustment
tool when making compensation adjustments.
3. Push AUTOSET or otherwise adjust your oscilloscope
to display a stable waveform.
4. Adjust the trimmer in the probe until you see a perfectly
flat-top square wave on the display. (See illustration.)
Standard Accessories
The accessories included with the probe are shown below.
WARNING. To avoid electric shock when using the probe
or accessories, keep fingers behind the finger guard of
probe body and accessories.
To reduce risk of shock, verify that the ground lead and
ground spring are fully mated before connecting the
probe to the circuit under test.
Item Description
Universal IC Cap
Use this cap to prevent shorting
the probe tip between IC pins.
Press the cap on the probe tip
until it snaps on, and then spin
the cap to expose the probe tip
toward the IC lead.

Ground spring
This spring minimizes
aberrations on high frequency
signals caused by ground
path inductance, giving you
measurements with good signal
fidelity.
Attach the spring to the ground

Revision A
Replacing the Probe Tip
Order Tektronix part number 206-0635-xx (P6139B) or
206-0636-xx (P5050B). The insulator sleeve, part number
204-1226-xx, is reorderable and is common to both probes.
WARNING. Only qualified service personnel should
replace the probe tip. Disconnect the probe before
servicing. After replacing the tip, securely tighten the
insulator sleeve before using the probe.

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. Using the probe or accessories in a manner not
specified could result in a shock or fire hazard.
To Avoid Fire or Personal Injury
Ground-Referenced oscilloscope use. Do not float the
reference lead of this probe when using with ground
referenced oscilloscopes (for example, DPO, MSO, and
TDS series oscilloscopes). The reference lead must be
connected to earth potential (0 V).
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 reference lead from the circuit under test before
disconnecting the probe from the measurement instrument.
Avoid electric shock. To avoid injury or loss of life, do not
connect or disconnect probes or test leads while they are
connected to a voltage source.
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.
Avoid electric shock. When using probe accessories, never
exceed the lowest rating of the probe or its accessory,
whichever is less, including the measurement category and
voltage rating.
Avoid electric overload. To avoid injury or fire hazard, do
not apply potential to any input, including the reference
inputs, that varies from ground by more than the maximum
rating for that input.
Avoid exposed circuitry and do not operate without
covers. Do not touch exposed connections and components
when power is present.
Inspect the probe and accessories. Before each use, inspect
probe and accessories for damage (cuts, tears, defects in
the probe body, accessories, cable jacket, etc.). Do not use
if damaged.
Do not operate in Wet/Damp conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.
