Hi,
Actually I have designed individually customized boards for the pulser(lm96550), Beamformer (lm96570), tx/rx switch (tx810) with reference of Tx_sdk_v1.
The below Image shows the beamformer p,n channel logics and respective HV pulser output with resistive(2.2k ohm) load with out capacitor.
Then I applied the HV pulses to inputs of switch(Tx810) , And again observed the o/p pulser which is shown in below image.
Here the pulser o/p are connected to switch i/p using female connectors. If I disconnect and observed then clean pulser o/p pulses are observed. Just after connecting to switch o/p the signal is getting distorted like shown in above image and beamformer o/p also(p,n channels).
Tx_en given by 10hz(100ms) logic pulse. And observed the default pulse patterns at beam former p,n o/p channels. Which are interfaced to pulser i/p channels.
Can you help me interface of transducer, pulser o/p and switch i/p. And observe the echo signals at pulser o/p.
thank you.
regards,
chandu.
