This paper introduces the generalized excited pair coherent state (GEPCS).Using the entangled state |η> repre sentation of Wigner operator,it obtains the Wigner function for the GEPCS.In the ρ-γ phase space,the variations of the Wigner function distributions with the parameters q,α,k and I are discussed.The tomogram of the GEPCS is calculated with the help of the Radon transform between the Wigner operator and the projection operator of the entangled state |η1,η2,T1,T2>.The entangled states |η> and |η1,η2,T1,T2) provide two good representative space for studying the Wigner functions and tomograms of various two-mode correlated quantum states.
