Test results of the SAMPA-based Front End Cards with Readout Chambers for the NICA TPC

The Time Projection Chamber (TPC) is the main tracking detector of the NICA Multi-Purpose Detector (MPD). It is a well-known detector for 3-dimensional tracking and particle identification of high multiplicity events. Readout Chamber (ROC) is multiwire proportional chamber with cathode pads. Front end electronics is one of the important element of the TPC. The system contains 95232 channels. Front End Card (FEC) design is based on SAMPA ASIC. Some test results of the FECs with ROC chamber are presented.
