|The first HBA spectrum, with all 96 channels. The tall peak in the middle of the |
plot is actually our test signal (which will be switched off later).
|The first LBA spectrum. At this stage, there are only two channels, as only one aerial had been installed.|
These tests demonstrate not only that the antennas themselves are working, but that the signal processing chain is functioning up to the beamformer. Checking the beamformer is the next step in our commissioning.
