The non-archimedean power series spaces Ap(a,t) are the most known and important examples of non-archimedean nuclear Fréchet spaces. We study when the spaces Ap(a,t) and Aq(b,s) are isometrically isomorphic. Next we determine all linear isometries on the space Ap(a,t) and show that all these maps are surjective.
