The state-of-the-art high voltage probe series PHVX establishes itself with its first 4kV model PHVX4kV as the best-in-class solution for the growing demands of power electronics design, e.g. low side VDS measurements in double pulse testing of high-speed high-voltage switching devices of SiC technology, and IGBTs, thyristors, fast-switching HV diodes, and more.
All PHVX series models are engineered to deliver precise and consistent results, allowing designers to optimize the efficiency and performance of their power electronic systems with confidence.
With <3pF low input capacitance and a bandwidth exceeding 600MHz, the PHVX series ensures accurate and reliable measurements for fast-switching devices and power electronics, making it an essential tool for engineers working on advanced designs having a protected test environment.
The PHVX series probes have a universal BNC output connector and are compatible with any oscilloscope in the lab with 1 MΩ input impedance.
PMK’s PHVX series probes are not for handheld use and for integration into full-automated or manual test stations for high-voltage safety reasons. All PHVX probes are therefore used as a voltage-measuring component (permanently attached device) of a test system.
The probe series impresses with its innovative and compact form factor. Individual contacting with high signal fidelity in different applications is ensured with the replaceable spring tip and a variety of contacting accessories for high voltages. Particularly the unique ground ring, which can be rotated through 360° and thus enables direct contacting to 5.08 mm pitch square pin headers without adding any additional capacitive loading to the DUT for highest signal fidelity. In addition, there is a wide range of soldering adapters, BNC adapters, and other accessories for easy and save connectivity for this non-handheld probe.
Each voltage model is available in different cable lengths and configurations, w/o intelligent read-out function, and w/o additional Silicon insulation (S) for high power measurements. The optional read-out (RO) features intelligent communication with automatic scaling on the oscilloscope display. The fully equipped model with intelligent read-out and extra Silicon insulation end with nomenclature -S-RO.
Step 1: Select base PHVX probe
Read-Out (RO) in our probes is a physical pin, positioned in the BNC adapter. This read-out pin allows automatic adjustment of the oscilloscope's settings, like scaling, based on the probe's attenuation factor so that the read out on the probe is correct.
