Hi All,
I am trying to make a system which supplies a large burst mode AC signal to a piezo and then short circuits the terminals once the burst is over( here in the literature).
The system has a Function Generator attached to a High Power amplifier which is attached to the leads of the piezo. I know how to program the function generator to give burst signal of a certain number of cycles, but how can I short circuit the terminals after the burst is done? The measurement is too fast to short circuit by hand.
Frequency: 20kHz
Voltage (out of the amplifier): ~50V
Piezo impedance: 10 Ohms (resonance drive)
Thanks in advance.
