General Safety Summary
Review the following safety precautions to avoid injury and prevent
damage to this product or any products connected to it.
Injury Precautions
Avoid Electric Overload. To avoid injury or fire hazard, do not apply
potential to any input, including the common inputs, that varies from
ground by more than the maximum rating for that input.
Avoid Electric Shock. To avoid injury or loss of life, connect the probe
output to a measurement instrument before connecting the test leads
to a voltage source. Do not disconnect the probe from the measure-
ment instrument while the test leads are connected to a voltage
source. Use only probe accessories that are rated for the application.
Avoid RF Burns While Handling Probe. To avoid RF burns, do not
handle the probe while the input leads are connected to circuits
above the voltage and frequency limits specified in Figure 2 on page
13. Use only probe accessories that are rated for the application.
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.
Product Damage Precautions
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 only a damp cloth.
Refer to the cleaning instructions on page 16.

Getting Started
This section describes the P5210 High-Voltage Differential Probe
and gives instructions on how to install and functionally test the
probe.
Features and Accessories
The P5210 probe (Figure 1) provides a safe means of measuring
circuits with floating high voltages. The probe outputs a low-voltage,
ground-referenced signal for display on instruments with the
TekProbe interface (or any oscilloscope or other measurement
instrument when used with the Tektronix 1103 TekProbe power
supply).
The P5210 probe allows clear and accurate measurements of
high-speed transitions and provides excellent rejection of common-
mode signals. Both inputs have high impedance and low capaci-
tance. Because of these features, the probe can safely and accurately
measure the fast voltage transients in switching power devices
without risk of damage.
Other applications for the P5210 probe include testing high-voltage
motor control circuits and line connected circuits in switch-mode
power supplies.
The probe has a number of design features to protect you from high
voltage. This protection extends up to the full input rating of the
probe.
The probe head and input cables are double insulated.
The control buttons and probe housing are non-conductive and
isolated.
The probe housing is internally shielded with a connection from
the shield to earth ground through the output cable.

WARNING. To avoid shock or burn hazard, use only the standard
accessories or accessories that are rated for the application. Use the
P5210 accessories with this product only.
Keep your fingers behind the finger guard on the probe body
whenever possible to reduce the risk of a shock from the circuit under
test.
Differential Inputs. The inputs are CAT II rated to a
maximum of 2,200 VRMS between either input and
earth ground. They are also rated for a maximum
difference of 4,400 VRMS between the inputs with less
than 5,600 V(DC +peak AC)) between the inputs or
between a single input and ground.
Attenuation Range. In the raised position the range
button sets the attenuation to 1,000X. In the lowered
position the range button sets the attenuation to 100X.
Use the 1,000X position for measurements up to a
maximum of 4,400 VRMS. Use the 100X position for
better signal resolution on connections below
440 VRMS.
OverrangeIndicator. The overrange indicator lights red
if the voltage of the input signal exceeds the linear
operating range of the probe. When this happens, the
signal on the probe output does not accurately represent
the signal on the probe input.
Overrange Beeper. In the raised position the overrange
button sets the overrange beeper to sound whenever the
overrange indicator lights.
Bandwidth Select. In the raised position the bandwidth
button sets the full bandwidth (50 MHz). In the
lowered position the bandwidth is restricted to
approximately 5 MHz.

P5210 Instructions 7
Input Leads. The input leads of the differential probe
connect to the probe tips. The connectors are 4 mm
insulated banana plugs and are double insulated for
safety.
NOTE. Use only accessories that are rated to the
maximum input voltage under test.
TekProbe Interface. The TekProbe interface provides
power, signal, and probe characteristic data transfer.
If your oscilloscope does not support the TekProbe
interface, you can use the optional 1103 probe power
supply as an effective interface. Contact your local
Tektronix representative for more information.
Zero Adjust. Use the zero adjust to set the probe output
to the zero reference point prior to making measure-
ments. Use the adjustment tool provided.

6-32 Probe Tip
Finger
Guard Probe Body. The probe body is designed for personal
safety, ergonomic comfort, and signal fidelity. The
body is rated for the maximum input voltage of the
P5210 probe.
The probe tip is a 6–32 threaded post that accepts the
hook tips provided with the probe.
The finger guard provides protection when the hook
tips are not being used. Keep your fingers behind the
finger guard whenever possible to reduce the risk of a
shock from the circuit under test.
Use only accessories that are rated for the application.
Substitution of other accessories may create a shock or
burn hazard.
Keep the probe body and accessories clean to reduce
the risk of shock due to surface conduction. Refer to
page 16 for cleaning instructions.
Small Hook Tip. Use the small hook tip for making con-
nections to small conductors such as component leads.
The hook tip is rated for the maximum input voltage of
the P5210 probe.
Install the small hook tip by sliding it over the body of
the probe and screwing it onto the threaded probe tip.
To use the tip, hold the probe body and pull the tip
shield back. Hook the tip onto the circuit and release
the shield.
