We present simulated results of the fundamental performance of our Exoplanets Tracker (ET) type instruments including current ET type instruments at Kitt Peak (KPNO ET), and Apache Point Observatory (Multi-object APO Radial Velocity Exoplanet Large-area Survey= MARVELS), as well as the new generation of Extremely Precision Extrasolar planet Tracker (EXPERT) and an infrared version ET (IR ET) instruments. The simulations begin with our universal simulated fringed spectra generator, which can produce fringed spectra for stars with a wide variety of spectral types. We can also input the desired velocity shift to the simulated spectra easily. Then the produced simulation datasets are reduced by the real data reduction pipeline. The simulations enable us to obtain the ideal Doppler precision that our instruments can achieve when observing different types of stars. The results create an important reference database for us to evaluate the performance of our instruments and to design the appropriate observing strategy (especially exposure time) for each instrument. In this poster,we will present the simulated Doppler precision for EXPERT, discuss its capability of discovering small planets and show the preliminary simulated results for the IR ET.
