Description
About the DP-02VF 150MHz High Frequency Differential Probe
The DP‑02VF is an 80V, 150MHz high‑frequency differential voltage probe engineered for precision measurement in today’s fast‑switching power‑electronics and high‑voltage environments. Designed to deliver clean, accurate and isolated differential measurements, it allows any oscilloscope, DAQ or data recorder to safely analyze floating or high‑potential signals while the instrument itself remains properly grounded. This makes the DP‑02VF an indispensable tool for engineers working with modern high‑speed, high‑efficiency power‑conversion systems.
The DP‑02VF 80V 150MHz high frequency differential voltage probe is an important accessory for any application involved in power electronics and high voltage systems. These probes allow isolated, floating and safe measurements with any oscilloscope, DAQ or data recorder, allowing the oscilloscope to remain grounded while input signals float at other voltage levels. Using a DP‑02VF Differential probe, differential and floating (isolated) measurements can be made on a variety of AC power systems like 460V/230V/110V AC input power supplies, chopped and switching power supplies, thyristor controllers, variable‑speed motor drives (PWM signals), motor inrush current and current‑shunt measurements.
To ensure secure, high‑integrity connection to test points, the DP‑02VF uses two 4mm safety banana sockets as its isolated input interface. A BNC output provides seamless compatibility with oscilloscopes and DAQ systems, enabling stable, low‑noise waveform capture even in high‑frequency, high‑EMI environments.
The DP‑02VF differential isolation voltage probes are powered from a battery or an external power supply, offering flexibility for both laboratory and field applications. With excellent common‑mode rejection, high input impedance and robust insulation, the DP‑02VF delivers the accuracy and reliability required for advanced power‑electronics diagnostics.
Engineers in R&D, system validation, industrial maintenance and academic research rely on the DP‑02VF for high‑bandwidth differential accuracy, safe floating operation and consistent oscilloscope performance. Its combination of speed, safety and measurement fidelity makes it a trusted choice for modern high‑frequency power‑electronics design and troubleshooting.
