Does onetesla support frequency above 20kHz

Postby phao92 » Sun Apr 28, 2019 12:20 pm

Hi
I'm a potential buyer and would like to know whether I can hook up a function generator through the MIDI jack if it supports frequency above 20kHz?
I want to play with high voltage high frequency electricity.

best regards.

The frequency of the coil is already very high (270 KHz) - unfortunately it is not possible to modulate the output much past 1KHz because of duty cycle limitations.

Ok thanks. Does this mean that it wont play a sound past 1KHz?

It can, but I don't know how performance will be past 1KHz.

Ok thank you. One last question, according to the definition of duty cycle is how long it's on each pulses and frequency is how many times per second.
I can't see the change in duty cycle if you change the frequency?
Please correct me if I'm wrong.

The coil has a minimum pulse width (a few cycles at 270KHz) it needs to ring up and output voltage, which means as the period becomes smaller the duty cycle becomes higher.
