General Safety Summary
Review the following safety precautions to avoid injury and prevent damage to
this product or any products connected to it.
Only qualified personnel should perform service procedures.
Injury Precautions
Product Damage
Precautions
Avoid Overvoltage. To avoid electric shock or fire hazard, do not apply potential
to any terminal, including the common terminal, that varies from ground by
more than the maximum rating for that terminal.
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.
Do Not Operate Without Covers. To avoid electric shock or fire hazard, do not
operate this product with covers or panels removed.
Do Not Operate in Wet/Damp Conditions. To avoid electric shock, do not operate
this product in wet or damp conditions.
Do Not Operate in an Explosive Atmosphere. To avoid injury or fire hazard, do not
operate this product in an explosive atmosphere.
Keep Probe Surface Clean and Dry . To avoid electric shock and erroneous
readings, keep probe surface clean and dry.
Do Not Operate With Suspected Failures. If you suspect there is damage to this
product, have it inspected by qualified service personnel.
Do Not Immerse in Liquids. Clean the probe using a soft cloth dampened with a
mild detergent and water solution. Do not use any other chemicals or abrasives.

Features and Accessories
The P6138A probe is a compact, high-impedance, 10X passive probe designed
for use with Tektronix TDS 400 series digitizing oscilloscopes. The P6138A
probe meets the requirements of UL3111-1 for ground-referenced applications
and is fully compatible with the Tektronix family of 3.5 mm probe accessories.
NOTE. Remove and discard the protective cover on the tip of the probe before
attempting to connect a probe tip accessory.
Table 1 illustrates the features and accessories of the P6138A probe.
T able 1: Features and Accessories
Feature/Accessory Description Applications/Notes
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.
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.
P6138A Instructions
SureFoot probe tips Provides fault-free probing of SMD packages that have lead
spacings of 25 mil JEDEC or 0.65 mm EIAJ. To connect,
simply push the SureFoot onto the probe tip and then probe
the SMD package. The tines of the adapter prevent the probe
tip from slipping or shorting to adjacent leads.
The list of optional accessories on page 8 includes SureFoot
tips for probing SMD packages with lead spacings of 50 mil
JEDEC or .5 mm EIAJ.
Low-inductance ground Connects the probe ground to a ground reference close to the
signal source. The short lead minimizes aberrations on
high-frequency signals caused by the inductance of the ground
lead.

Probe Compensation
Because of variations in oscilloscope input characteristics, check and adjust the
low-frequency (LF) compensation when you connect the probe to a different
oscilloscope input.
Figure 1: Low-frequency compensation
Use the following procedure to compensate the probe.
1. Connect the probe to the probe adjustment signal on the oscilloscope.
2. Press AUTOSET or otherwise adjust the oscilloscope so that it displays a
meaningful waveform.
1 kHz
LF
3. Turn on the 20 MHz bandwidth limit of the oscilloscope.
4. Turn on the high-resolution acquisition mode of the oscilloscope.
5. Adjust the trimmer in the probe as shown in Figure 1.
