 +Data recorder to ATNF V016B
 +
 +Using room temp S-band Rx.
 +
 +Agilent set to 7.8 GHz
 +
 +From top of rack 3:
 + LCP -> (400 MHz LPF) -> (30 dB amp) -> (Atten 12 dB) -> Splitter
 +
 + ​Splitter_out_1 -> (Freq translator RF 1)
 + LO1 (R & S SML) = 837 MHz
 +
 + ​Splitter_out_2 -> (30 dB amp) -> (Atten 20 dB) -> Splitter2
 +
 + ​Splitter2_out_1 -> Spectrum analyser
 +
 + ​Splitter2_out_2 -> (Freq translator RF 2)
 + LO1 (R & S SML) = 869 MHz
 +
 +The 400 MHz BPF was put in at ~02:26 UT to try and improve stability by blocking RFI. It helped a little bit but Tsys measurements from PCFS are still not to be trusted.
  
 No data recorded between 02:50 and 03:35 because I forgot to reset the recorder duration after fringe check! No data recorded between 02:50 and 03:35 because I forgot to reset the recorder duration after fringe check!
