INTRODUCTION
The XFVP probe is a novel voltage probe that provides high voltage isolation via fiber optic
cables. Not only is this approach advantageous from the voltage isolation point of view, but is
also immune to typical radiated interferences and capacitances created when using long
coaxial measuring cables. The XFVP probe was designed to minimize input capacitance as this
is what hurts most high frequency measurements.
Also analog optical links are prone to slight power variations due to connector mismatches,
temperature drifts and offsets. We use a proprietary algorithm to calibrate the link and cancel
those. This increases overall accuracy as compared to other optical equipment and saves lots
of setup time during research and testing. Moreover the XFVP probe can do “hot” calibrations
with no input disconnect, which translates into saved time and increased user safety making it
unnecessary to access the high voltage area during operation. Another useful feature puts in
standby or turns off the probe head from the receiver so that the user does not have to access
areas that can be at high voltage during tests.
Most high-end oscilloscopes feature proprietary input connectors that force the user to choose
among the supplied accessories of the scope. XFVP probe can be used in any 50
Ω
terminated
oscilloscope. This gives developers freedom to use their favourite digital scope and reduce
overall investment costs at the same time. Lastly the back of the probe head features a
standard camera tripod mount thread. This makes it more convenient to place the probe inside
tightly spaced cabinets or power modules and maintain proper clearance distances.
