Basic procedures

Start and stop

Tuning of DASH345/BAND8 for continuum observations

  1. Set antenna EL angle to 60 degrees
  2. Login to aste-1c with asteobs
    > ssh asteobs@aste-1c
  3. Select CONT BE
    asteobs@aste-1c: swbox_ctl_be CONT           <--- CONT BE is selected
    asteobs@aste-1c: swbox_ctl_be
    status: swbox_ctl_be CONT
  4. Select either of DASH345 and BAND8 and then, set the synthesizer B
    [DASH345]
    asteobs@aste-1c: asterx_sw DASH345           <--- DASH345 is selected
    ...
    asteobs@aste-1c: synthe_ctl B FREQ 14.375    <--- 14.375 GHz x24 = 345 GHz
    asteobs@aste-1c: synthe_ctl B
    FREQ = 14.375000000 [GHz]                    <--- confirm the frequency is set
    AMPL = 20.00 [dBm]
    RF   = ON

    [BAND8]
    asteobs@aste-1c: asterx_sw BAND8             <--- BAND8 is selected
    ...
    asteobs@aste-1c: synthe_ctl B FREQ 12.0      <--- 12.0 GHz x36 = 432 GHz
    asteobs@aste-1c: synthe_ctl B
    FREQ = 12.000000000 [GHz]                    <--- confirm the frequency is set
    AMPL = 13.00 [dBm]
    RF   = ON
  5. Tune DASH345/BAND8
    [DASH345]
    asteobs@aste-1c: asterx_set DASH345
    ### Query of LO Freq ###
    LO Freq = 345.000000000                      <--- confirm LO freq = 345.000
    ...
    Set ATT     : Pol0=225, Pol1=310
     Pol0 =      225   , Pol1 =      310
     Pol0 = 0.005490[A], Pol1 = 0.007567[A]
     Pol0 = 0.662948[V], Pol1 = 0.778741[V]
    
    If necessary, adjust ATT values with loatt_dash345.

    [BAND8]
    asteobs@aste-1c: asterx_set BAND8
    ### Query of LO Freq ###
    LO Freq = 432.000000000                      <--- confirm LO freq = 432.000
    ...
    > GET_PA 0 
    3.380737,279.586792,-0.291290
    > GET_PA 1 
    4.022064,228.485107,-0.489655
    
    If necessary, adjust ATT values with lopwr_band8.
  6. Select sidebands and polarizations
    asteobs@aste-1c: swbox_ctl_pol 0 1           <--- P0USB and P1USB are selected
    asteobs@aste-1c: swbox_ctl_pol
    status: swbox_ctl_pol 0 1
    400:P0-USB	402:P1-USB
  7. Adjust input levels to DASBOX (TBD)
    [DASH345]
    asteobs@aste-1c: cont_if 2 22
    changed Cont IF #2 att. = 22 [dB]
    ...
    Cont IF #2 Lev. = -0.000264 [V]
    asteobs@aste-1c: cont_if 3 17
    Cont IF #3 Att. = 0 [dB]                     <--- Just ignore even if 0 [dB]
    changed Cont IF #3 att. = 0 [dB]
    ...
    Cont IF #3 Lev. = -0.000301 [V]
