P5100A 500 MHz 100X High Voltage Probe Instructions

Operating Information
Standard Accessories
The P5100A Probe is a high impedance probe with
100X attenuation that is designed for use with Tektronix
ground-referenced oscilloscopes.
The probe includes the accessories shown below.
WARNING. Do not substitute accessories from other
products for use with this probe. Only use the
accessories that are included with this probe.
Connect the probe as shown in the illustrations below.
To avoid electric shock when using the probe or
accessories, keep your fingers behind the finger guard
of the probe body and away from the shaded area shown
in the accessory illustrations below.
500 MHz 100X High Voltage Probe
Compensating the Probe
Due to variations in oscilloscope input characteristics,
the low-frequency compensation of the probe may need
adjustment after you move the probe from one oscilloscope
channel to another.
Connect the probe to the oscilloscope channel that you
plan to use for your measurements.
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
x P071288202*
Push AUTOSET or otherwise adjust your oscilloscope
to display a stable waveform.
Adjust the trimmer in the probe until you see a perfectly
flat-top square wave on the display. (See illustration.)

Common spring (TACS)
Use this accessory to limit
aberrations on high frequency
signals caused by common
lead path inductance.
Bend the spring to reach
nearby connections (~1 in).
Small hook tip (TASH)
Use this tip to access test
points in tight spaces. Screw
the hook tip onto the probe tip
and then clamp the hook onto
the circuit.
Rating: 1000 V CAT II
Note: Only the 1000 V CAT II
rating is applicable when used
with the P5100A probe

IEC 61010-1). Rated for indoor use only.
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 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.
