Clearance requirements
The unique common mode voltage range of the measurement system allows it to be used in the presence of high frequency/high voltage common mode signals. It is important to observe all precautions while using this product.
WARNING:Electrical shock can occur while using this measurement system. The system is intended to isolate the operator from hazardous input voltages (common mode voltages); the plastic case of the probe head and the shield on the probe tip do not supply safe isolation. Maintain the safe clearance from the probe head and probe tip while the measurement system is connected to the energized circuit as recommended in this document. Do not access the RF Burn Hazard Zone while taking measurements on a live circuit. |
The following figure shows the components of the measurement system and the potential RF burn area when working with hazardous voltages. The RF burn area of 1 m (40 in.) is indicated by the dashed lines surrounding the probe head.
WARNING: Risk of RF burns. Refer to the following derating curve to identify the danger areas. To avoid RF burns, do not operate the probe within limits of the gray shaded area in the graph. |
WARNING: There is a risk of burn from elevated temperatures on the tip when continuous wave or high duty cycle burst common mode signals are between about 10 MHz and 50 MHz. This causes the tip ferrites to dissipate significant power at voltages lower than found on the following graph. To avoid the burn risk, keep the tip temperature at 85°C (185°F) or lower by limiting the applied common mode voltage and/or duty cycle, lowering the ambient temperature, and/or applying forced convection airflow. |

Operating information
Use this section to help you use the probe safely and effectively. Read all safety information before installing your measurement system to be aware of the operating and clearance requirements, including possible hazardous areas when the measurement system is connected to the DUT.
TICP block diagram
The following figure shows a block diagram of the Tektronix Active Isolated Current Shunt Probe.
The common-mode resistance and capacitance to earth ground is shown in the figure. The common-mode resistance is shown as infinite with the probe since it is galvanically isolated and can be ignored. The common-mode coupling capacitance to earth ground and the surrounding circuit is shown as the bridging capacitance. This capacitance will be approximately 20 pF when the probe head is placed 6 inches (15.25 cm) above a ground plane.
- When possible, choose a reference point in the device-under-test (DUT) that is static potential with respect to earth ground.
- Connect the coaxial (common) shield of the probe tip to the lowest impedance point of the circuit.
- Increasing the physical distance between the probe head and any conductive surface will reduce the capacitance.
- When using multiple TICP probes to measure different points in the circuit that do not have the same common-mode voltages, keep the probe heads separated to minimize the capacitive coupling.
Measurement system handling best practices
The measurement system consists of quality parts and should be treated with care to avoid damage or degrading the performance due to mishandling. Consider the following precautions when handling the probe and tips.
- Do not crush, crimp, or sharply bend the probe cable..
- Do not twist the cable.
- Do not allow kinks or knots to develop in the probe cable.
- Avoid putting tension on the probe cable.
- Do not pull or jerk the cable, especially when kinks or knots are present.
- Do not drop the probe head or comp box assembly. This can result in damage and misalignment of the internal components.
- Avoid over-bending the probe tips; do not exceed the minimum bend radius of 2.0 inches (5.1 cm).
- Avoid crushing the cables by accidentally running over the cable with a chair wheel or by dropping a heavy object onto the cable.
- Store the measurement system in the supplied carrying case when not in use.

Procedure
What to do next
Connecting to a circuit
The following steps describe the process for connecting the TICP Series probe to an oscilloscope and the device under test (DUT).
Before you begin
WARNING:Do not connect the measurement system to an energized circuit to avoid the risk of shock. Always de-energize the circuit-under-test before installing or removing the tip cable from the circuit-under-test. The plastic case of the probe head and the probe tip of the probe cable do not supply the isolation. |
WARNING:To avoid the risk of electrical shock or RF burns while the DUT is energized, do not touch the probe head or probe tip while taking measurements. Always keep a 1 m (40 in.) clearance from the probe head during the measurement. See Figure 1. |
WARNING:To prevent the arc flash caused by a different potential, do not place the probe head or probe tip on the circuit that has the different voltage. |
CAUTION:To avoid possible damage to the equipment, do not connect the coaxial (common) shield of the probe tip or SMA input to the high impedance portion of a circuit. The additional capacitance can cause circuit damage. Connect the coaxial (common) shield to the low impedance section of the circuit. |
Note:Touching the probe head or probe tip cable when measuring a high frequency common mode signal increases the capacitive coupling and can degrade the common mode loading on the circuit-under-test. |
Note:To avoid inaccurate measurements, do not stack the separate probe heads and keep cell phones at least three feet away while taking measurements. |
About this task
Verify the DUT is not connected to an energized circuit. To obtain the most accurate measurement, allow the probe to warm up for 5 minutes.
Procedure
Tripod adapter installation
The following steps describe installing the tripod adapter to the probe head and attaching it to a tripod.
Procedure
Bipod installation
The following steps describe installing the bipod to the probe head.
Procedure
- Squeeze the handles of the bipod together to open the clamp.
- Place the probe head into the clamp and release the handle so the probe is as the angle needed to connect to the DUT.
Connecting the SMA adapter
The following steps describe the process for connecting the TICPSMA SMA tip adapter to the probe head and SMA cable.
Before you begin
Note:It recommended to connect SMA cable to the SMA adapter first and then connect the SMA adapter to the probe head. |
Procedure
Installing the probe tip adapters
There are two Tektronix probe tip adapters to connect the MMCX probe tips to pins on the circuit board. The MMCX-to-0.1-inch (2.54 mm) pitch adapter and the MMCX-to-0.062-inch (1.57 mm) pitch adapter.
One end of each adapter has an MMCX socket for connection to an IsoVu MMCX tip cable. The other end of the adapter has a center pin socket and four common (shield) sockets around the outside of the adapter. Notches on the adapters can be used to locate the shield sockets. The procedure for installing these adapters are the same, the main difference is the spacing of the pins on the circuit board.
To install the adapters onto the square pins, line up the center of the adapter with the signal source pin on the circuit board. Use the notch on the adapter to align one of the shield sockets to the common pin on the circuit board. The following figures show examples of lining up the adapters on the circuit board.
To achieve the best electrical performance, especially the CMRR performance and EMI susceptibility, place the probe tip adapter as close as possible to the circuit board.
After lining up the adapters gently push down on the adapter to seat it in place on the circuit board.
Installing the square pins on the circuit board
The following figure and table shows the recommended clearance requirements for connecting the adapters to the square pins on the circuit board. The bottoms of the adapters are shown at the top.
Figure reference | Probe Tip Adapter, MMCX to 0.1” pitch sq. pin 0.635 mm (0.025 in) sq. pins | Probe Tip Adapter, MMCX to 0.062 in pitch sq. pin 0.406 mm (0.016 in) sq. pins |
---|---|---|
1 | Recommend maximum pin length 6.00 mm (0.235 in) | Recommend maximum pin length 4.40 mm (0.170 in) |
2 | Minimize area between adapter and circuit board | |
3 | Keep out area (diameter of each adapter) | |
4 | Avoid or minimize components within keep out area |
The 0.025-inch (0.635 mm) square pins should already be located on the circuit board. Some square pins might have headers installed on the circuit board. Tektronix recommends removing the plastic spacer from the square pins to gain closer access to the circuit board as shown in the following figure to achieve the best electrical performance, especially CMRR. You might need to use a pair of tweezers to remove the spacer as shown in the figure.
Tektronix provides a set of solder pins (0.018-inch (0.46 mm) diameter) to install on the circuit board for use with the MMCX to 0.062-inch (1.57 mm) adapter. Use the soldering aide tool accessory (Tektronix part number, 003-1946-xx) to install these pins on the circuit board.
The solder pins are extremely small and can be challenging to handle. Tektronix recommends using tweezers and a magnifying tool when installing the pins on the circuit board.
The solder pins can be installed around a surface mounted component on the circuit board, but adequate clearance should be maintained for a good electrical connection for the adapter. Figure 1
Note:The coaxial (common) shield of the probe tip and tip adapters should always be connected to the lowest impedance point (usually a circuit common or power supply rail) in the circuit-under-test (relative to the probe tip cable/center conductor) to obtain the most accurate waveform. |
Use the following steps to install the solder pins using the soldering aide on the circuit board:
- Carefully insert the solder pins into the soldering aide as shown in the following illustration.
- Use the soldering aide to hold the square pins in place while soldering the square pins to the circuit board.
- If necessary apply a small amount of adhesive to further strengthen the connection to the circuit board. However, keep the height of the adhesive to a minimum to provide good electrical contact for the adapter. Figure 1
Probe Setup menu
Use the probe setup menu to see probe information, perform self-calibration (SelfCal), perform AutoZero, change the range mode, and configure the range.
To access the Probe Setup menu on the oscilloscope, double-tap the corresponding analog channel badge on the settings bar and tap Probe Setup.
You will receive a warning message if you connect the probe to the oscilloscope without a probe tip attached. The following images display the menu with and without the tip warning.
Self-calibration
The self-calibration (SelfCal) function that corrects gain accuracy and DC offset. These parameters change as the probe warms up to the operating temperature and remain constant once the temperature reaches steady-state.
Check the SelfCal Status in the Probe Setup menu. The status indicates when SelfCal has Passed, Failed or if it is Recommended to run SelfCal.
To check the status of the SelfCal remotely, use the SELFCAL:STATE?
PI command to determine self-calibration is RECOMMENDED
, RUNNING
, or PASSED
.
- Tap the channel badge corresponding to the channel you connected the probe to.
- In the channel menu, expand the Probe Setup tab.
- Tap the SelfCal button.
To run the self-calibration remotely, use the CH<x>:PROBE:SELFCAL EXECUTE PI
command. The connected channel is specified by "x".
Note:For the best results, run self-calibration while the probe is connected to the powered down DUT. |
When using vertical scales of 10 mV/div or less, probe self-calibration should be run with the probe tip still attached and with no signal applied to the probe tip. Additionally, for the TICPSMA and TICPMX1X tips, it is recommended to leave a representative drive impedance (a powered-down DUT) connected to the probe tip during self-calibration.
At higher vertical scales, or in the particular use case of a TICPSMA or TICPMX1X tip driven by a very low impedance (a shunt resistor ≤5 Ω), an alternate approach of disconnecting the tip from the probe head may be used to insure no signal is applied during self-calibration.
The TICP Series probe takes five minutes to warm up and self-calibration takes less than two minutes to complete. The SelfCal Status will change to Passed or Failed.
AutoZero
AutoZero and self-calibration work on different parts of the measurement system. Self-calibration optimizes measurements through adjusting parameters in the probe. AutoZero is an oscilloscope function and is used when a displayed waveform is not centered correctly (for example; due to a small DC offset error). AutoZero automatically runs after self-calibration.
It is important to power-down the DUT or disconnect your probe from the DUT before running AutoZero.
Auto Range
The Range Mode is selectable for either Auto or Manual. When the Range Mode set to Auto, the probe range is automatically selected when the V/div knob on the oscilloscope is turned. The relationship between probe range and V/div setting matches that shown in Ranges and 4/5/6 Series MSO Volts/div settings table.
Ranges
The measurement system has a variety of ranges available for you to select, whether the probe is being used with or without a tip. This allows for tradeoffs to be made between noise and dynamic range depending on the needs of the measurement being made.
CAUTION:To avoid damaging the probe, do not exceed the Peak Voltage rating for a given tip or the probe head. The Maximum Non-Destruct Voltage limit (Peak Voltage) does not increase when the Probe Ranges are changed. |
In 4, 5, and 6 Series MSO Instruments, the ranges are selectable when Range Mode is set to Manual. The recommended V/div settings are displayed in the table below. The ranges shown are for the probe SMA input and 1X tip. Multiply the range and V/div setting by the tip attenuation to get the values for a probe tip.
4/5/6 Series MSO probe ranges | Recommended V/div setting |
---|---|
20 mV | 2 mV/div |
30 mV | 5 mV/div |
45 mV | 5 mV/div |

When using a tip, the label of each probe tip shows the maximum dynamic range and the attenuation factor. When more sensitive ranges are selected, dynamic range is limited. Refer to the Linear differential input voltage range in the specifications table for more information.
Selecting a probe tip
CAUTION:Avoid over-voltage conditions that can damage or degrade the probe head input termination by selecting the correct probe tip. Selecting the correct probe tip attenuation factor is crucial to ensure that the probe head input termination is not degraded or damaged by an over-voltage condition. Select the probe tip that will provide the lowest attenuation possible for the signal being measured. |
When selecting a probe tip for a particular application, consider the following questions:
- What is the maximum RMS/Peak Voltage at the test point being measured (for example, under a fault condition)?
- What is the minimum single-ended input resistance that my circuit can tolerate?
- How large of a signal do I want to display at one time on the oscilloscope?
- What sensitivity do I need (for example, the minimum V/div setting)?
The following table will help you select the correct probe tip. Start at the top of the table and work down. Choose the first tip that meets all of your criteria.
Probe tip | Most sensitive V/div setting | Dynamic range | Maximum non-destruct voltage (DC + pk AC) | Single-ended input resistance |
---|---|---|---|---|
TICPSMA | 1 mV | ±0.5 V | ±3 V | 50 Ω |
TICPMM1 | 1 mV | ±0.5 V | ±3 V | 50 Ω |
TICPMM10 | 10 mV | ±5V | ±15 V | 500 Ω |
TICPMM100 | 100 mV | ±50 V | ±60 V | 5000 Ω |
For maximum non-destruct voltage refer to the Maximum differential input voltage vs frequency derating graphs.
Deskew
Each probe comes loaded with nominal propagation delay values that can be automatically applied through the Vertical menu on the oscilloscope. Deskew accuracy can be improved using a known signal and a deskew fixture. When the timing relationships between waveforms is critical, always deskew your test system with known equipment.
Input offset
The measurement system provides an adjustable input referred offset voltage.
This enables viewing a portion of the signal that is off-screen or examining sensitive behavior riding on a larger differential voltage. For example, a 0 V to 0.6 V step would normally exceed a ±0.5 V input range. By applying 250 mV of offset, the 600 mV step is brought into the dynamic range of the probe and can be viewed accurately. Offset is applied by the probe.
Voltage range
The probe is designed to enable characterization of high frequency circuits with a wide range of differential voltages in the presence of common mode voltages. Understanding the limits and differences between the voltage ratings as discussed in this section is essential to optimize signal fidelity and measurement accuracy.
Although the common mode voltage range of the probe is very large (1000 V CATII), the differential input range is limited and depends on the tip attenuation, the gain range selected, and the applied offset.
The input voltage conditions are divided into several different input ranges.
Common mode voltage range
The probe head is isolated from earth ground, making the common mode input range 1000 V CATII. The differential input range is more limited and refers to the signal that can be applied across the probe tip, regardless of the common mode voltage.
Differential voltage range refers to the actual measurement that will appear on the oscilloscope screen when using IsoVu™. For accurate results, the measurement must fall within the range of any applied offset ±Vdiff range of the tip.Vmeas=Voffset±Vdiff
Offset voltage range
Offset voltage can be applied through the oscilloscope Vertical menu settings. The input offset capability of the probe extends from ±0.5 V to ±50 V depending on the tip used. This offset is applied at the probe head and can be useful to bring applied signals within the dynamic range (Vdiff) of the probe.
Maximum non-destruct differential voltage range
The maximum non-destruct differential input range is the maximum differential voltage that can be applied to the input without damaging the probe. This is a DC +peak AC rating (no portion of the differential input signal should exceed this value). The maximum non-destruct differential voltage varies from ±3 V to ±60 V depending of the probe tip being used. Exceeding these levels will cause permanent damage to components of the probe head.

Application Examples
Application examples for Wide Bandgap (WBG) and PMIC power integrity.
WBG example (800V, 40 A typical; 0.125 Ω shunt)
In a 800 V SiC circuit switching at 40 A, a 125 mΩ shunt will produce a 5 V signal. To measure this using the TICP the 10X tip must be used. In the ±3.5 V range apply 0.3 V of offset.
The measurable current range goes from 52 A to -4 A. At these settings, the RMS noise floor at 250 MHz bandwidth is 2.2 mA RMS
PMIC power integrity (48 V, 3 mA typical; 1 Ω shunt)
On a 48 V PMIC bus, the standby current of 3 mA will produce a 3 mV signal on a 1 Ω shunt. Use the 1X tip in the most sensitive ±20 mV range, apply offset to view the 3mA current and capture transients from 0 A to 40 mA with a RMS noise floor of 21.2 µA
