Receiver temperatures measured during the commissioning of APEX-2

 

T_rec vs. RF range measured on site: LSB tuning and USB tuning

These measurements were taken using the average value of the FFTS backend every GHz for the 4 GHz of IF. The specified frequency is the central RF frequency and the sideband is also specified. The measured temperatures are in a T_SSB scale.

T_rec vs. IF measured on site at discrete RF frequencies

These measurements were taken using the FFTS backend combining the 4 GHz of IF. The specified frequency is the central RF frequency and the sideband is also specified. The measured temperatures are in a T_SSB scale.
