Tuning

  1. Start tuning on COSMOS GUI
    • Group/Project/Filename: aste16/calib16/EPAD3ph.tune
  2. Adjust receiver and E/O
    1. Login to aste-1c
      [asteobs@aste-mx1 ~]$ ssh aste-1c
    2. Set receiver automatically
      1. Adjust automatically
        [asteobs@aste-1c ~]$ asterx_set DASH345
        ### Query of LO Freq ###
        LO Freq = 351.635748072
        ---
        Set ATT     : Pol0=291, Pol1=285
         Pol0 =      291   , Pol1 =      285
         Pol0 = 0.007105[A], Pol1 = 0.006958[A]
         Pol0 = 0.683780[V], Pol1 = 0.780141[V]
    3. Adjust input power levels for E/O #1 and #2
      1. Stop chopper at R position
        [asteobs@aste-1c ~]$ mmc1_rstop
        ---
        20160905t042245z /cosmos3/naoj/sbin/mmc1_com.exe: execute end.
        20160905t042245z close_mmc(): socket '4' closed.
        20160905t042245z /cosmos3/naoj/sbin/mmc1_com.exe: normal end.
      2. Adjust input power level for E/O #1
        [asteobs@aste-1c ~]$ ifeo_tune 1 0.030
        volt=0.030000
            E/O att. =  8 dB      E/O att. =  8 dB    IF level=0.005563
        new E/O att. =  8 dB    IF level=0.005608
        new E/O att. =  6 dB    IF level=0.231108
        new E/O att. =  8 dB    IF level=-0.016370
         8 dB  -0.016370 V
      3. Adjust input power level for E/O #2
        [asteobs@aste-1c ~]$ ifeo_tune 2 0.050
        volt=0.050000
            E/O att. = 12 dB    IF level=0.132759
        new E/O att. = 12 dB    IF level=0.130974
        new E/O att. = 13 dB    IF level=0.105633
        new E/O att. = 14 dB    IF level=0.079953
        new E/O att. = 15 dB    IF level=0.060120
        new E/O att. = 16 dB    IF level=0.049238
        new E/O att. = 15 dB    IF level=0.071862
        new E/O att. = 16 dB    IF level=0.050086
        16 dB  0.050086 V
      4. Stop chopper at SKY position
        [asteobs@aste-1c ~]$ mmc1_sstop
        --- 
        c1_com.exe: execute end.
        20160905t042402z close_mmc(): socket '4' closed.
        20160905t042402z /cosmos3/naoj/sbin/mmc1_com.exe: normal end.
      5. Check y factor 1 and 2
        [asteobs@aste-1c ~]$ yfactor 1
        ---
            E/O att. =  8 dB
         E/O IF level = 0.004084 V
        R=0.005628 V,  Sky=0.004084 V, Y=1.392684 dB
        1.392684
        [asteobs@aste-1c ~]$ yfactor 2
        ---
            E/O att. = 16 dB
         E/O IF level = 0.030501 V
        R=0.051811 V,  Sky=0.030501 V, Y=2.301079 dB
