The leader in optical isolation—PMK optical isolation FF-1500

In power electronics measurement, as the demand for wide bandgap measurement increases, high-bandwidth, large-voltage probes have become a development trend. In this trend, optically isolated probes have emerged

It uses optoelectronic isolation technology, using fiber optic transmission for signal transmission between the probe and the oscilloscope, which avoids the effects of parasitic capacitance and inductance caused by traditional cable transmission

This greatly increases the bandwidth of the probe. Therefore, optical isolated probes can be considered a powerful tool for solving power electronics problems

Germany's PMK delivers a perfect answer in this regard. The PMK optical isolation probe offers the industry's highest bandwidth—1.5GHz—and features an extremely high common-mode rejection ratio

CMRR is >180dB at DC-500kHz and 80dB at 1GHz. These are specifications that Tektek, Lyco, and Rohde & Schwarz cannot achieve

PMK's photoisolated probe front-end interface uses a compact angled probe design, allowing measurements to be conducted in confined spaces. At the same time, this design allows for the use of shorter attenuation heads

can reduce the stress and antenna effects applied to the test points, enabling higher signal fidelity measurements

To accommodate various types of oscilloscopes on the market, the FF-1500 uses a universal BNC interface, making it compatible with any oscilloscope with an input impedance of 50Ω or 1MΩ

greatly facilitates engineers' signal acquisition in practical applications

The FF-1500 is powered by an easy-to-swap, rechargeable industry-standard 18650 battery and can operate continuously at room temperature for up to 30 hours. Therefore, the probe itself has no fan and operates very quietly

At the same time, it has excellent temperature characteristics, with low drift and offset over a wide temperature range, making it convenient for engineers to measure

The interface box of the FF-1500 needs to be powered by PMK's PS power supply, which comes in two types: PS-02 two-channel power supply and PS-03 four-channel power supply, both equipped with remote control functionality

Therefore, both have USB interfaces and optional network ports. The FF-1500's remote control allows for biased control and can be programmed via Python

The FF-1500 high-voltage optical isolation probe boasts industry-leading performance, capable of accurately parsing high-bandwidth, small-difference signals under high common-mode voltage

and ultra-high common-mode rejection performance across the entire bandwidth make it an ideal measurement solution for GaN and SiC device characterization and system-level design development
