If you want something really interesting with LV excitation,
try this....
Get a variable square wave generator with good p-p output capablity.
If it's too weak to use directly, put it though a solid state direct
coupled
amp.
Connect the generator through a small rf choke to two zeners wired
"back to back" to the primary.
GEN ------------////////----------->|----|<----------o
RFC ZENERS to TC primary
GEN----------------------------------------------------o
The gap drop can be simulated with the zeners acording to whim or
available equipment.
Adjusting the period of the generator will approximate different BPS
rates and their effects on the system.
If you don't have a generator handy, I suppose a lv transformer would
work, but you're stuck with 120 BPS.
Have fun!!
