The remaining controls and features of the probe are located on the probe head.
Probe Inputs
The maximum voltage that the probe inputs can accept depend on the probe model and the measurement points.
For example, the THDP0200 probe (shown) can measure a maximum of 1,000 V II between either input and ground, and a maximum difference of 1,500 V (DC + peak AC) between the (–) and (+) inputs. These input ratings are valid for both range settings.
The other probes covered in this manual have different limits; refer to Specications. (See Table 6 on page 27.)

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.

THDP0200 150 V >150 V 1500 V >1500 V
TMDP0200 75 V >75 V 750 V >750 V
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 mode voltage specication). The maximum common mode voltage limits vary between probes, from 550 V C AT I for the TMDP0200, to 2300 V CAT I for the THDP0100 probe. You should consider both specications when choosing a probe for your measurement task. Some examples that illustrate this are shown on the following pages.

Example 2. Next, assume that the same waveforms from the previous example are 120° out of phase w ith 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

Operating Basic
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, rst 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 specied 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

Twistin
Twisting the input leads helps to cancel noise from high-EMI environments that is induced into the input leads.
de rejection decreases as the input frequency increases. For example, if you apply a 60 Hz line voltage of

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 Specications section. As the graph shows, the probes have virtually

Specication
The specications shown apply to the THDP/TMDP series probes installed on Tektronix MSO/DSO4000 oscilloscopes. When a probe is used with another oscilloscope, the oscilloscope must have an input impedance of 1 Mand a bandwidth equal to or greater than the probe. The probe must have a warm-up period of at least 20 minutes and be in an environment that does not exceed the limits described. (See Table 5.) Specications for the THDP/TMDP series probes fall into three categories: warranted, typical and nominal characteristics.

WARNING. Use only an i nsulated tool to make the adjustment. Failure to do so presents a potential shock hazard.
9. Disable the generator output.
10. Reverse the probe input leads to the generator.
Adjustments
11. Invert the signal and trigger slope on the oscilloscope to display the rising edge of the signal. Adjust the trigger level
if necessary.
12. Enable the generator output and make the adjustments in the following order: long-term –LF, long-term –LF*, short-term
–LF. (The long-t
erm –LF* adjustment is not used in the TMDP0200 probe.) Repeat this sequence as necessary to
optimize the square-wave response.

Troubleshooting
Host Instrument Firmware
Some instruments may require a rmware upgrade to support full functionality of the latest probes that are offered by Tektronix. Instruments with lower versions of rmware may not display a ll 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 rmware, go to www.tektronix.com/probe-support to download the latest rmware.
To check the rmware 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.
Signal Display
probe is connected to an active signal source and you do not see the signal displayed on the oscilloscope:

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 s olvents. 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.
Service
There are no user-serviceable parts in the probes. If your probe requires service, contact your Tektronix service representative or repair center for instructions on returning your probe for repair.
