Hi sir,

thank for your reply, it is very useful for me. 

I have some more doubts, please guide me sir.

1)  For transducer connection at SMA connectors in Tx_sdk_v1, manual mentioned that need to remove capacitors (CB51-CB58). But I am not understanding what and how to remove the SMD capacitors in Tx_sdk_v1 board?.

2) Actually I dont have +/-50v DC power supplies so I tried to generate +/-15v pulses at pulser o/p's by giving vpp(50v)=15v, vnn(-50v)=-15v, vdd=10v, vdn=-10v ,vsub=-20v, 3.3v, 1.8v ,-5v ,5v supplies to phoneix connectors pins of Tx_sdk_v1 board. But GUI is not getting connected I am facing error as shown below.

 3) i was bought just the Tx_sdk_v1 board. when first time I was connected the opall kelly board and Tx_sdk_v1_REVB board reibbon cable and to the system. I found LEDs in opal kelly board and DOTP1 led in tx EVM board were on(with out giving the vsub +/- 50v, +/-10v 3.3, 1.8v etc). But now  led DOTP1 led off , after setting the setup with +/-15v supplies and I am got error mentioned above. Is there any problem sir, please let me know if any.

    Already this is second time I  bought the Tx_sdk_v1, so please help me sir.

thank you.

regards,

chandu.
