LeCroy HVFO-1M-FIBER Test Probe Extension Set, For Use With HVFO Isolated Probe

Teledyne LeCroy HVFO103 60MHz High Voltage Fibre Optically Isolated Probe and Accessories

The Teledyne LeCroy HVFO103 (RS 136-8330) is a high voltage (HV) fibre-optically isolated 60MHz oscilloscope probe that is designed for the measurement of small signals floating on a high voltage bus in power electronics designs. Optical isolation between the probe tip and the oscilloscope input reduces adverse loading of a device under test. It also reduces noise, distortion, ringing, overshoots, and transients on the measured signal. It far surpasses the measurement capabilities and signal fidelity of both conventional HV differential probes and acquisition systems that rely on galvanic channel-to-channel and channel-to-ground high voltage isolation. Furthermore, it mitigates reliance on dangerous test setups that require floating the oscilloscope and probe, or investments in specialized isolated oscilloscope or data acquisition systems that result in other performance compromises.
The HVFO103 architecture is simple, with a single laser and fibre optic cable providing optical isolation and modulated signal + data communication. Selectable tips are available for various operating voltage ranges. The HVFO103 is small enough to fit in tight spaces, provides the performance required for real-world needs, and is affordable enough to accommodate tight equipment budgets.
