Software Levels

In international mode, the station has 4 software levels, but only 3 of which are used extensively. Levels are performed iteratively, so mode 3 will contain any services running from mode 1 and 2.

Software Level 0 (Off)

Software level 0 is the default mode the station is in after handover, and should be returned to before handback. In this state, all of the RSP, beaforming and calibration services are stopped and the station is inactive. Between observations the station is sometimes returned to software level 0 to ensure there are no rogue beams, statistic collectors, etc still running from a previous observation.

Software Level 1 (Station Monitoring)

Software level 1 initialises some low-level daemons and the station monitoring and control software. Observations cannot be performed in this mode.

Software Level 2 (Hardware Initialised)

Software level 2 loads images onto the RSPs, enables the RCUs and performs some other low-level operations to prepare the station. While correlation statistic observations should be taken in this mode (XST, ACC), no beamformed observatons can be performed in this mode. 

Software Level 3 (Software Initialised)

Software level 3 starts the beamforming and calibration services. This is the default mode the station should be in while performing any beamformed observations (any non-XST/ACC observations).
