The SYNOPtic page displays (Refer to
Figure 21 TOAD synoptic display):
• Antenna state (TRACKING, SLEWING, STOWED etc.)
• Weather conditions. Note that the weather condition quality (i.e. Fine)
refers to Antenna safety, not observing data quality due to weather!
• Cryogenics system status
• Environment temperatures
• Power / Generator status
• Subreflector position and status
• Paddle status
• Receiver and Turret status and positions, as well as center frequency
• Millimetre switch position
• Upstairs attenuators and samplers (B6)
• Laser diode status (B5)
• MOPS samplers
o GTP = Gated Total Power expressed in scaled units. Ideal range is
between 0.2 – 1.0
o SDO = Noise injection in % over the signal floor.
o Tsys per sub band (i.e. each is a 2 GHz wide band!)
o Tsys sigma = standard deviation of the Tsys over the specified
amount of time. You can reset those calculations by pressing the
“Reset / Restart Tsys sigma calculations” at the top of the screen.
