Hi Chandu,
I am sorry for your trouble. But did you power up the 1.8V supply before powering the 3.3V supply? (As you posted on Aug 12). You should power up the 3.3V then the 1.8V supply.
Regards,
Charles

hi,
I have some doubts in powering the EVM.
1) J_SUB pin at 1-2 position to minimize power supplies, then what is power on sequence?
I think power on sequence -50v ,1.8v, 3.3v , +/-10v. +50v, am I right ?
but here -50v powered on early is there will be any problem, since the original power on sequence Vsub, 1.8v, 3.3v , +/-10v. +/- 50v.
2) when J_SUB pin at 2-3 position, V sub should be most -ve or atleast equal to -50v so could I use Vsub= -50v.
3) to generate pulses at pulser out put we are giving +/- 50v , I want generate <50v pulses (15v or 20v) Is possible with this evm? To do that how much voltage needs to be given at Vsub, +/-50v bannana pins.
4) With out giving power supplies(Vsub, +/-50v and etc..), Just I connected opal kelly board and transmit solution to the PC. Then is it possible to connect through the GUI, That is clicking on the connect button in GUI. I am facing error so is it possible to connect GUI with out all power supplies or with some power supplies?
thank you.
regards,
chandu.
