Figure 3: Logical signal path for 400 MHz observations. All frequencies shown are in MHz.

Figures 1 to 3 show the logical signal paths for the front of the racks. Near complete signal paths exist simultaneously for the two main setups at 1400 Mhz and 600/400 MHz. Several pieces of equipment are duplicated to make this possible. In particular, there are separate down converters and LOs.

To change from 600 or 400 MHz to 1400MHz only the following minimal changes should be required.
