Don't include the \n in the commmand. fprintf will append the default terminator (LF) for you when writing the command.

...
command = ':SOUR:POW:AMPL -63 DBM';
fprintf(t, command);
...

Hi Siva,

It looks like you're running into an issue when connecting to your hardware using "tcpip" function.

I found the following article by the MathWorks support team which may be helpful.

Do try the steps mentioned in the above article.
