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.

4P5210 Instructions

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.
