Calibrating the TV Explorer
The picture shows the calibration screen in terrestrial mode. RP-080 generates two frequencies in this band, 85 MHz and 750 MHz and the TV Explorer will automatically detect them and show the values on the side bars. If we work with RP-050, which generates one single frequency in the terrestrial band, then the centre bar will be used.
Due to measurement resolution limitation users can always expect the cablibration to indicate some minute numerical loss.
