P5120 High-Voltage Probe Instructions
Features and Accessories
The P5120 is a passive high-voltage probe designed for use with
TPS2000 series instruments. The probe feat ures a floating reference
and is ideal for measuring and troubleshooting power supplies and
high-voltage devices. The probe provides 20X attenuation of signals
up to 1000 V
P5120 probe is certified to international safety standards.
The P5120 probe has features and accessories to make high-voltage
measurements safer and easier. Please take a moment to familiarize
yourself with these features and accessories and their uses.
WARNING. Do not substitute accessories from other products for
those provided with the P5120. The accessories for the P5120 have
been safety tested. The use of non-tested accessories may cause
injury.

Probe Body -- The P5120 probe body is designed for personal
safety, ergonomic comfort, and signal fidelity.
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.
The probe tip is a 6--32 threaded post that accepts both standard and
optional accessories.
Keep the probe body and accessories clean to reduce the risk of shock
due to surface conduction.

P5120 features and standard accessories (Cont.)
Compensation Box -- The compensation box contains low- and
high-frequency compensation adjustments. The high-frequency adjustments are accessible by removing the compensation box cover. Refer
to Adjustment Procedures on page 7.
Adjustment Tool -- Use the supplied adjustment tool for probe com-
pensation adjustments. Do not use metallic or conductive tools while
making adjustments.
Color Markers -- The matching markers help you identify probe in-
puts at a glance. Clip one marker near the probe head and the matching marker near the compensation box as shown.

Small Hook Tip -- Use the small hook tip for making connections to
small conductors such as component leads.
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. The hook tip will firmly
hold the conductor under test.

Large Hook Tip -- Use the large hook tip when working with larger
components such as bolt terminals and buss bars typically found in
power distribution equipment.
Install the large 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. The hook tip will firmly hold the
conductor under test.
Reference Leads -- The P5120 probe comes with a long and a short,
floatable reference lead. Both reference leads connect to a removable
crocodile clip.
Attach the reference lead to the probe body by inserting the probe
head into reference lead as shown.
The length of the reference lead directly impacts the fidelity of high-frequency signals. The longer the reference lead, the more the signal will
be distorted. For more information about the reference lead and signal
quality, go to page 5.
Crocodile Clip -- The large crocodile clip attaches to the insulated
banana connector on the reference leads.

WARNING. For safe electrical connections, use the crocodile clip
provided. Do not attempt to substitute the crocodile clip with any
other accessory.

Attach the adapter by pressing it onto the 6-32 probe tip and making
sure that the reference clip makes contact with the probe reference.
WARNING. Do not connect the Probe-to-BNC Adapter to a floating or
high-voltage source. The BNC adapter is only rated to 500 V (DC +
peak AC) with the probe reference connected to earth ground.

P5120 High-Voltage Probe Instructions
Operating Basics
To get guaranteed performance from the P5120 probe, please read
and apply the information in this section.
Maximum Nondestructive Input Voltage
The P5120 probe is designed to be used in a hi gh voltage environment; however, the voltage input rating of the probe starts to
decrease at about 2 to 3 MHz. Please refer to the Specifications
section of these instructions for the maximum input voltage and
frequency derating information.
Reference Lead Length
Always use as short a referenc e l ead as possible between the probe
head and circuit reference for high frequency or fast rise time
signals.
The input capacitance of the probe and the series inducta nce added
by the probe tip and reference lead can result in a resonant circuit;
this circuit may cause parasitic “ringing” visible within the
bandwidth of your oscilloscope. Refer to Figure 1.

Figure 1: Waveform distortion from reference lead length
P5120 High-Voltage Probe Instructions
Reference

Operating Basics
Parasitic ringing is not a concern when the probe is used with low
frequency or slow rise time signals and is not apparent if the
frequency content is beyond the bandwidth of the oscilloscope.
Probe Loading
When you touch your probe tip to a circuit element, you are
introducing a new resistance, capacitance, and inductance into the
circuit. Refer to Figure 2.

Figure 2: Probe loading equivalent circuit
Frequency and impedance of the source determine how much the
probe loads the circuit you are measuring. As the frequency of the
source starts to increase beyond 1 kHz, the input impedance of the
probe begins to decrease. The lower the impedance of the probe
relative to that of the source, the more the probe loads the circuit
under test. Refer to Figure 12 on page 21 for a graph of frequency
versus input impedance.
The probe has virtually no loading effect on sources with relatively
low impedance and low frequency.

P5120 High-Voltage Probe Instructions
Adjustment Procedures
The low-frequency (LF) compensation of the P5120 probe must be
checked every time the probe is connected to a different oscilloscope
input.
The high-frequency (HF) compensation should be checked if the
probe was repaired or fails to meet rated bandwidth specifications.
Check the probe using the performance verification procedures on
page 15 to determine if adjustment is required.
LF Compensation
Before taking any measurements with the probe, first check the LF
compensation of the probe and adjust it to match the channel input it
is connected to.
1. Connect the probe to the Probe Comp signal on your TPS2000
instrument and then press AUTORANGE.SeeFigure3.Usethe
reference lead connection to obtain the proper waveform.

Adjustment Procedures
Opening the Compensation Box
NOTE. This procedure should be performed by qualified service
personnel only.
To open the cover, obtain two small screwdrivers and use them to
unlatch the tab as shown in Figure 6.
WARNING. Avoid damaging the tab. A damaged tab will allow the
cover to easily separate and expose the user to the electrical
potential of the reference connection.
To avoid damaging the tab, do not attempt to press on the tab
through the hole in the cover where it latches. In the event of a
damaged tab, replace the probe.
Perform the following procedure to open the compensation box.
1. Insert the flat blade of small screwdriver (A) into the location
shown in Figure 6. Insert the blade until it stops against the back
of the tab.
