After some testing, the transducer receiving works ok with oscilloscope without connecting to TDC1000-GASEVM, but connecting gives me nonsense noise.... (about 150mV negative, and a lot of noise).
After some checking, without connecting external tranducers, I can see the 30Volts in TX1 (square pulses), and I see the same signal (only 5V square pulses, possibly limited by schottskys) in the RX2.
I've the TDC1000-HV EN1 and EN2 enabled. The time needed must be calculated or the square pulses doesn't work.
What can happen? The noise from TX1 makes unusable the RX2 in some interval of time (hundred of microseconds).
Thanks.
Best regards.
