Page 8: General Description
Version 1.0 GENERAL DESCRIPTION The VFCT is a passive device. It contains no active electronics. It has a rise time as low as 120 ps, corresponding to 3 GHz upper frequency cutoff (-3 dB). The differential output signal is provided by two SMA connectors which must be measured using 50Ω... -
Page 9: Vfct Main Advantages
Strong output signal droop shall be expected, if observed pulses are longer than a few 10 nanoseconds. • Eddy current losses can heat up VFCT ceramic break or its interior parts. This may lead to malfunction if power losses are excessive. -
Page 10: Operating Principle
VFCT User Manual Version 1.0 OPERATING PRINCIPLE VFCT CHARACTERISTICS VFCT bandwidth is limited by a lower and an upper cutoff frequency. Lower cutoff frequency The droop is equal to D = 2πf Where D [1/s] is the droop [Hz] is the lower cutoff frequency (-3dB) The droop is also equal to τ... -
Page 11: Upper Cutoff Frequency
VFCT User Manual Version 1.0 Example of VFCT output signal droop: Observe on the plot below the effect of a transformer’s lower cutoff frequency, i.e., its droop. -t/τ Upper cutoff frequency The upper cutoff frequency (-3dB) is the consequence of a complex combination of elements: a) The eddy currents which are developing inside transformer cores. -
Page 12: Specifications
VFCTs are equipped with two SMA jack connectors with PTFE dielectric. OUTPUT SIGNAL POLARITY The VFCT is bipolar. Arrows are printed on the outer surface of the sensor. Charges (positive) crossing the aperture in the direction of the arrow give positive outputs. For example, an electron beam (= negative charge) passing in the direction of the arrow yields a negative output. -

Page 14: Installation
A cable segment is any section of cable between two grounded connectors or bulkheads, for example through a grounded patch panel. In-flange VFCT bolts must be tightened at the recommended torque according to the flange type, but not beyond. Common mode filters To improve EMI rejection common mode filters should be installed at both ends of each cable segment. - Page 15 If you have any questions, feel free to contact us by e-mail info@bergoz.com Bergoz Instrumentation – 156, rue du Mont Rond – Espace Allondon Ouest – 01630 SAINT GENIS POUILLY – France Tél. : +33 (0) 459 42 66 42 Fax : +33 (0) 450 42 66 43 – bergoz@bergoz.com www.bergoz.com...
