About HORNET® Probe Series

The state-of-the-art high voltage differential probe series HORNET® establishes itself as the best-in-class solution for the growing demands of wide bandgap power electronics design, e.g. double pulse testing of high-speed high-voltage switching devices of SiC technology, and IGBTs, thyristors, fast- switching HV diodes, and more.
HORNET®’s ±4000V differential and common mode voltage capability provide engineers with the flexibility to tackle the most challenging high voltage applications in power electronics design.

With a bandwidth exceeding 300MHz, HORNET® ensures accurate and reliable measurements for fast-switching wide bandgap, SiC, power electronics, making it an essential tool for engineers working on advanced designs having a protected test environment.
HORNET® is engineered to deliver precise and consistent results, allowing designers to optimize the efficiency and performance of their power electronic systems with confidence.
The probe is designed with advanced safety features to safeguard both users and the equipment during high voltage measurements. Anyhow, HORNET® series probes are not for handheld use and for integration into full-automated or manual test stations for high-voltage safety reasons. HORNET® is therefore used as a voltage-measuring component (permanently attached device) of a test system.

The HORNET® series probes have a universal BNC output connector and are compatible with any oscilloscope in the lab with 50Ω input impedance, or 1MΩ input impedance and a 50Ω feed-through termination.
All HORNET® series models require a power supply, which is not included in the scope of delivery, and has to be ordered separately. Review the Ordering Information at the end of this document for more details. The interface box is powered by the required PMK power supply. The referring power supplies all have remote control capabilities and therefore a USB interface and optional additional LAN interface. As an alternative for most flexible use, the 1 channel battery pack power supply AP-01 provides >8h of portable and isolated operation but has no software remote control.
HORNET® series has the capability to be controlled from either remote control or the controls located on the interface box.

• For remote control PMK offers the software “PMK Probe Control” with graphical user interface, which is shipped with any PS2 and PS3 power supply, and is available for download at: http://www.pmk.de/en/products/probecontrol
• In addition, the Python package “PMK-probes” is available as a programming interface for controlling PMK’s active probes. Installation instructions, examples and documentation is available at: https://pmk-probes.readthedocs.io/en/latest/

Measurement Principle
The high voltage differential probe series HORNET® consists of two balanced precision attenuators, which are differentially matched. The attenuators scale the input voltage before passing into the differential amplifier. The output of the differential is fed over a driver stage to the 50 Ω input of a measuring device.

Factory Calibration
All models are shipped with factory calibration certificates. Annual factory re-calibration is recommended. ISO17025 calibration upon delivery or as re- calibration is possible on request.

Specifications

Read the Instruction Manual before first use and keep it for future reference. A digital copy of the latest Instruction Manual revision can be downloaded at www.pmk.de.
Do not exceed the specifications. Allow the probe to warm up for 20 minutes. This probe comes with 1 year warranty. Each specification is determined at +23 °C ambient temperature. This probe series is not for hand-held use, and not rated for CAT II, III or IV.

General Information

Read the “Safety and Handling Information” in this manual before first use.
When using HORNET® series non-hand-held probes install it in a safety environment only, e.g. a tester application. Probe configurations via remote control are recommended.

Download “PMK Probe Control” PC software or Phython package from www.pmk.de

Make all required probe settings before the measurement starts. To prevent electrical accidents, read the safety instructions and this entire manual carefully, and observe the five safety rules of the German standard EN 50110-1.

This is not a hand-held probe. Make sure the probe is installed in a safety environment. and configured completely prior to its operation.

Handling Information
Adjust the input coupling of the measuring instrument to 50Ω before connecting the probe to it. After connecting the power supply, you hear a short triplet of signals from the buzzer and the LEDs on the probe head will blink.
Connect first the BNC output to the oscilloscope, then connect the probe inputs to the deenergized circuit under test.

Best practice: Drill the input leads twice for best CMRR but acceptable bandwidth degradation.

For use in environments with high levels of electro-magnetic interference (EMI), the noise suppression kit is recommended, and to be installed on the signal cable near the interface box.

Adjust the attenuation and offset correction if needed. After all settings are made, the probe is ready to be used as component of the measurement system.

For removing the probe’s input from the DUT, or for changing the configuration via the knobs at the probe head, make sure the circuit under test is de- energized.

Probe Head Indicator Layout

Use the probe head’s control buttons only if the circuit under test is de- energized. Remote control is recommended.

Keylock
If no key is pressed 10 seconds after opening the menu the keypad will be locked. Press the “Set” button again to release it.

Use the probe head’s control buttons only if the circuit under test is de- energized. Remote control is recommended.

Global Offset
By pressing “Set” you can switch between the set global offset position and zero. While in setup menu, this function is not available. Also with set “Hold Overload” an occurring overload event must be cleared before switching offset zero position is available.

Use the probe head’s control buttons only if the circuit under test is de- energized. Remote control is recommended.

Setup Menu
Access the setup menu by holding the “Set” button for 5s. The Overvoltage- indicator LED of the output blinks green as confirmation.
The setup menu starts with the unlid/off LED 1000:1, the Channel Identification Color menu, menu point I.
The selected menu item is indicated by the attenuation LEDs.

Change the menu selection using buttons “1” and “2”. Use the
Buttons “5” and “6” configure the settings in the menu. Press “7”, the SET button, to exit the menu.

Use the probe head’s control buttons only if the circuit under test is de- energized. Remote control is recommended.

In the following LEDs are marked as x = unlit/off and o= lit/on.

Channel Identification Color ( x o o o ) – Menu point I
For channel identification the following colors (modes) are available: unlit, white, yellow, cyan, pink, blue, green, red.

Overload Buzzer ( o x o o ) – Menu point II
In case of detected overvoltage at input or output channel, the Overload Buzzer gives an audible signal and can be turned on- and off with Button “5”. Additionally, the Hold-Overload Buzzer can be activated with Button “6”. In case of detected overvoltage, the “Set” Button must be pressed to confirm and carry on.

Key buzzer ( o o x o ) – Menu point III
Activate the Key Buzzer, giving audible feedback when any Button on the keypad is pressed.

Offset synchronization ( o o o x ) – Menu point IV
Turn offset synchronization on and off.

Offset-Zero( o o o x ) – Menu points V – VIII
Adjust offset-zero per attenuation mode.

Reset Factory Default
By pressing both buttons “1+2” together while in setup menu, the probe resets to factory settings. Hold both buttons for 5s and wait until you hear a differing signal.

Use the probe head’s control buttons only if the circuit under test is de- energized. Remote control is recommended.

EMC Noise Suppression Kit
For use of PMK’s high-voltage differential probes in environments with high levels of interference, like in double-pulse tester applications for analysis of fast switching power devices, the EMC noise suppression kit 891-102-EMC is recommended. Recommended installation is on the signal cable near the interface box.

Please note that signal lines must never be laid parallel to pulsed lines. This also includes AC fields. Ensure that there is sufficient distance. The ferrites can be used in any order or individually.

Scope of Delivery

A PMK power supply is required for all models. See chapter “Ordering Information” to review the selection.
