Yes, It is needed with both power and ground as results may be different.

Your question is not very clear! The PSRR includes PSSR+ and PSRR-, pls see the picture! First u must know what to be simulated,PSRR+ or PSRR- .

 

[lijianheng]

It is PSRR+ & PSRR-, it depends on your application.

both of them will be tested
