Gaseous tracking detectors play a key role in existing and planned hadron and particle physics experiments. A universal tracking device has been set up for optimizing the performance of existing trackers (ANKE@COSY, WASA@COSY) and for developing new concepts (PANDA@FAIR). The setup consists of a drift gap followed by a GEM amplification stage and a stack of drift chambers. Additional scintillators above and below the setup give time reference signals for cosmics measurements. Data are read out with 160 MHz flash ADCs and with F1-TDCs. The setup will be described. Results on tracking resolution, cluster formation along cosmics tracks, gas amplification for various mixtures will be presented. The implication for particle identification based on the energy loss for e.g. straw detectors will be discussed.
