Can we perform OTF holography data analysis: data gridding, FFT, near-field correction etc.? |
Requires measurement for confirmation |
done |

Is the entire system sufficiently robust, capable of operating at least for hours without phase locks coming out of lock, or computer reboots? This is the ultimate holographic test for system stability. |

There should be adequate transmitter-receiver sensitivity |
Requires measurement for confirmation |
done |
Appears to be ok, but further checks need to be made. |

Receiver & backend: does it produce adequate amplitude and phase stability? |
Requires measurement for confirmation |
partially done |
Appears to be ok, but further checks need to be made. |

The holography feed illumination should be correct |
Requires measurement for confirmation |
done |
Checked 2006/11/09 |

The transmitter should be on the right frequency |
Requires measurement for confirmation |
done |
Checked several times a day. |

The holography receiver must be mounted and in focus |
Requires measurement for confirmation |
done |
Focus checked 2006/11/10. Set to -4mm. |
11 November 2006 |
The received signal should be available end-to-end, from transmitter to displayable data on disk |
Requires low-level data acquisition software |
done |
Implemented and tested. |

Data analysis: can we display amplitude and phase as a function of time, with the antenna stationary? This is needed for the receiver stability tests |
|
done |
Implemented and tested. |

The transmitter should be producing adequate power |
Requires measurement for confirmation |
done |
Looks ok. |

The telescope should be steerable |
(a) It must be possible to point the antenna into a chosen Az & El direction (b) It should be capable of performing cross-scans and OTF raster scans (c) It should be recording time-stamped Az-El coordinates during an OTF scan |
partially done |
Point (a) is done. Point (b) is not done. Point (c) is done. |

The transmitter should be illuminating the antenna correctly |
Requires measurement for confirmation |
done |
Transmitter has been realigned by Jack Meadows. Spot-on. |

The transmitter pointing should be adjustable with sufficient precision (NB we probably won't have the positioner that will be used at the OSF) |
Requires measurement for confirmation |
done |
Transmitter has been realigned by Jack Meadows. Spot-on. |

Can OTF data be recorded correctly, with antenna pointing data |
Requires measurement for confirmation |
done |
Verified by Robert Lucas. |
