In this report calibration of the four probes attached onto the JUICE spacecraft has been made.The JUICE spacecraft (JUpiter Icy Moon Explorer) is a spacecraft which will investigate theenvironment on and around Jupiter and its four biggest moons. On the spacecraft are 10different instruments onboard, where one of the instruments is the Radio and Plasma WaveInvestigator (RPWI). The mission of RPWI is to measure the electromagnetic field and plasmaparticles, among other things around the Jovian system. To analyse the measured data fromthe probe, the data has to be calibrated. In this report test data and raw flight data of the probeshas been calibrated by digital-analog converting the signal. The data SID 1 and SID 3, whichboth measure the electric field, the calibration was successful both for the ground test data andthe raw flight data. However, the calibration of SID 2, which measure the plasma density, didnot give the calibrated analog signal within expected range. Possible sources of error for thatdeviation includes error in the Fourier Transform of the transfer function. The raw flight data forSID 1 and 2 was further disturbed by solar wind, resulting in high measured signals for theelectric field and the plasma density. For future improvements this calibration method could berepeated on another set of data without disturbance to verify the calibration method and identifypotential source of error.
