Hi Valeri,
Since you are using the TX-SDK-V2, which has LM96550 High Voltage Pulser, you would be needing an external bench supply of +/- 40V to the pins VPF & VNF.
I apologize for the information provided earlier that ±40V are generated from ±50 V with 10V difference; because in TX-SDK-V1 it has LM96551 High Voltage Pulser which internally generates the +/- 40V from +/-50V supplied, with 10V difference.
Let me be back with the information you need shortly.
Thanks,
Rohit
