- Page 2 DIMENSIONS 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.
- Page 3 It is always recommended that the probe head be installed over a tripod mount and secured When manually positioning the probe head keep in mind the unit is physically joined to the receiver unit, moving the probe head may send the receiver into the floor www.saker-mv.com BR-XFVPL-Rev 2. 12/22...

- Page 5 ACCESSORIES Several accessories for the XFVP-L are available which include patch cables, attenuators and external power supplies. Consult the accessories list. COMPATIBILITY The XFVP-L probe requires an external oscilloscope with internal 50 termination. The Ω termination is needed to provide appropriate high-frequency transmission of the signal. If the oscilloscope does not have internal 50 Ω...
- Page 6 CAT rated for use on these types of circuits according to definitions of IEC/EN 61010-031. The accessories provided by Saker for connecting the probe head to the DUT are compatible with the touch protected SMB connector in the probe. Please refer to the accessories list.
- Page 7 Set the oscilloscope vertical scale at an appropriate scale given the conversion ratio of the XFVP-L and attenuator (see specifications section) in question. A 50 Ω termination is necessary for calibration and signal integrity. The preferred method of operation is as follows: 1.

- Page 9 Due to their non-conductive nature, fiber optic cables provide excellent isolation between probe head and receiver. However the probe head is floating at the same potential of the measured conductor. Thus the whole body of the XFVP-L probe head can be at hazardous potentials.
