Abstract :
This paper describes measurement system established for microwave low power measurement at TüBITAK UME. System was carried through the superheterodyne type receiver. The system was realized between 100 MHz to 26.5 GHz frequency range. Also error model of the system was analyzed. The output power of a signal source was measured between -60 dBm to -120 dBm. The expanded uncertainty (k=2) of the measured power is between 0.19 dB to 3.04 dB in all frequency range.
