Probe Operati
This section of the manual describes how to make connections to the instrument and to your circuit, followed by descriptions
of the probe controls and indicators.
ng Information
Connecting to the Instrument
1. Connect the probe to the input of the oscilloscope.
All of the LEDs on the probe body briefly light, and then indicate the settings from the previous session.
The Status LED on the probe control box lights amber as the probe completes a self-test.
The Status LED goes off briefly and then lights green to indicate the probe is ready to use.
2. Adjust the vertical offset (or position) of the oscilloscope input.
3. Select the proper range setting.
For example, when using the THDP0200 probe, to achieve higher resolution and less noise when measuring signals
below 150 V

30 VAC
RMS
Make sure that the accessories are fully mated before connecting or disconnecting.
WARNING. To avoid electrical shock or fire, make sure the test leads are in good condition. The input leads and extender
leads have a jacket wear indicator which becomes visible if the wire jacket becomes excessively worn. If the wear indicator is
visible, do not use the probe. Contact Tektronix Service for repair or replacement.
4. Use the probe accessories to connect the probe inputs to the circuit points to be measured. (See page 6, Accessories.)
WARNING. To avoid electrical shock or fire, keep the probe body and output cable of the probe away from the circuits being
measured. The probe body and output cable are not intended to be in contact with the circuits being measured.

To help you use the high voltage differential probes safely and effectively, this section provides important information about
safety limits, operating characteristics, and probing techniques.
ics
Operating Characteristics and Probing Techniques
This section explains the operating characteristics of the probes and includes techniques that you can use to maximize the
performanc
Operating Limits
The probes have two operating ranges that you select with the RANGE button; the ranges differ between probe models.
To keep within the linear measurement region of the probe, select a range that is above the differential voltage that you
are measuring. You can measure a voltage in the low range that exceeds the low range limit (provided it is within the high
range limit of the probe), but it will overdrive the circuitry of the probe. When this differential overrange occurs, the probe
detects the condition and lights the OVERRANGE indicator. Measurements taken in the lower, more sensitive range when
the OVERRANGE indicator is lit are not accurate during the Overdrive Recovery Time (ORT, typically <20 ns, depending
on the probe type).
Do not attempt to measure a differential voltage that is above the high operating range of the probe. (See Table 3.) Do
not exceed the common mode voltage on either input (+ or – input to ground). (See Table 6 on page 27.) The probe
can be damaged if these limits are exceeded.
The input signals that you attempt to measure must be considered both for the differential potential between each other
and for the amplitude on each input with respect to ground (the common m ode voltage specification). The maximum
common mode voltage limits vary between probes, from 550 V CAT I for the TMDP0200, to 2300 V CAT I for the THDP0100
probe. You should consider both specifications when choosing a probe for your measurement task. Some examples that
illustrate this are shown on the following pages.
THDP0100/0200 & TMDP0200 High Voltage Differential Probes Instruction Manual22

Measurement Examples
Example 1. Consider a case where you need to measure two sinusoidal waveforms that are 180° out of phase with each
other, each with an amplitude of 1000 V
s
with no DC offset (centered at 0 V). (See Figure 3.)

If both waveforms are at the same voltage potential, then the differential measurement would be 2 times the individual
signal inputs (in this example, 2000 V

probe model are shown in the figure above.

Operating Basic
Example 2. Next, assume that the same waveforms from the previous example are 120° out of phase with each other.
(See Figure 4.)
Although this is a lower potential between the inputs than in example 1, it exceeds the differential voltage ratings of the
THDP0200 and TMDP0200 probes, so you must use the THDP0100 probe.
This phase relationship yields a maximum differential of 1.732 times the individual signal inputs, or 1732 V

Overrange Detection
Differential voltage outside the operating range will overdrive the circuitry of the probe and distort the output signal. When
this differential overrange occurs, the probe detects the condition and lights the overrange indicator. With the Audible
Overrange ON, the probe will also emit an audible alarm.
WARNING. The Overrange indicator does not detect an overrange condition of common-mode voltages or voltage-to-earth
potential at the probe inputs. The Overrange indicator only detects differentially between the + and – inputs (not relative to
ground). Do not exceed the Common-Mode Voltage or Input Voltage-to-Earth ratings of the probe when taking measurements.
If you are not sure, first take a single-ended measurement of each point that you are intending to measure differentially.
Take a single-ended measurement by tying one input lead to ground (the – input) and then connecting the other lead (the +
input) to the points of interest, one at a time.
Common-Mode Rejection
The common-mode rejection ratio (CMRR) is the specified ability of a probe to reject signals that are common to both inputs.
More precisely, CMRR is the ratio of the differential gain to the common-mode gain. The higher the ratio, the greater the
ability o

Twisting the input leads helps to cancel noise from high-EMI environments that is induced into the input leads.

Probe Loading
When you touch your probe tip to a circuit element, you are introducing a new resistance, capacitance, and inductance into
e circuit. Frequency and impedance of the source determine how much the probe loads the circuit you are measuring. As
th
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. For a
graph of frequency versus input impedance, refer to the Specifications section. As the graph shows, the probes have virtually

Troubleshooting
Host Instrument Firmware
Some instruments m ay require a firmware upgrade to support full functionality of the latest probes that are offered by
Tektronix. Instruments with lower versions of firmware may not display all probe controls and indicators on screen, and in
some cases may require you to power-cycle the instrument to restore normal instrument operation. If you are having problems
with your probe and suspect that you need to upgrade your instrument firmware, go to www.tektronix.com/probe-support
to download the latest firmware.
To check the firmware version on Windows-based instruments, from the menu bar, click Help/About TekScope. On
Linux-based instruments, press the Utilities button on the front panel.
Error Conditions
LEDs Do Not Remain Lit
If none of the LEDs remain lit after you connect the probe, a probe/oscilloscope interface fault may exist. Perform the
following steps until you clear the fault or isolate the problem:
Disconnect and reconnect the probe to restart the power-on diagnostic sequence.
Connect the probe to a different channel on the oscilloscope.
Disconnect the probe from the oscilloscope, power-cycle the oscilloscope, and then reconnect the probe.
Connect the probe to a different oscilloscope.
If the symptoms remain (they follow the probe), then the probe is defective and must be returned to Tektronix for repair.

Cleaning
Protect the probe from adverse weather conditions. The probe is not waterproof.
CAUTION. To prevent damage to the probe, do not expose it to sprays, liquids, or solvents. Avoid getting moisture inside
the probe when cleaning the exterior.
Clean the exterior surfaces of the probe with a dry, lint-free cloth or a soft-bristle brush. If dirt remains, use a soft cloth or
swab dampened with a 75% isopropyl alcohol solution. Use only enough solution to dampen the cloth or swab. Do not use
abrasive compounds on any part of the probe.
