Where:

f = Maximum frequency in Hz

K = 3.45 ×10

. K is the scale factor to convert Farads to picoFarads and Amperes to milliAmperes

and a factor to allow cable capacitance to charge to 95% of the final charge.

C = Cable capacitance in picoFarads

V = Maximum peak measured voltage from sensor in volts

Icc = Constant current from current source in mA

Ib = Current required to bias the internal electronics, typically 1 mA
