NOTE
When performing a number of measurements it can be necessary to
repeat the calibration process due to temperature changes etc. This
is a regular behaviour. Furthermore, if you change the frequency
band, calibration has to be repeated. As soon as calibration is nec-
essary the 9102 will inform you by displaying the red “Calibrate“
icon.
