INTRODUCTION 

The XFVP-L 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-L  probe  was  designed  to  minimize  input  capacitance  as  this  is 
what hurts most high frequency measurements.  

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.
