The way to correct for the series resistance of the
generator, providing you know the secondary inductance, is
to calculate the total measured series resistance
=2*pi*f*L/Q, subtract the generator resistance from it, and
recalculate the Q.
To measure the generator resistance, if you have
a suitable voltmeter or scope, measure the open circuit
voltage and then load it with a resistance that drops the
voltage to one half. That will be the equivalent resistance
of the generator.
