Yes, below breakout the secondary response is linear and
this offers another method of calibration -
Put a small shunt resistor between secondary base and ground
so that a scope can measure the base current. Say 1 ohm so
that 1 volt on the scope corresponds to 1 amp of base current.
Run the system at a drive level below breakout.
Calculate the top voltage using the effective secondary
inductance Les obtained from JavaTC,
Vtop = 2 * pi * Fres * Les * base_current
Observe the response of the E-field probe and work
out the calibration factor. With care this could be
accurate to 5%.
