New switch box for Nov 2011
Figure 4.2: Overview of band combinations observable after the Nov 2011 upgrade (with a new switching box). See below for the Oct-2012 upgrade.

  • General band selection rules:
    • Only four IF outputs (of 8GHz for E0, E2, E3, or of 4GHz for E1), from a single receiver or any of the band combinations E0/E1, E0/E2, E1/E3, can be used simultaneously.
    • Only a maximum of 4 inner bands can be selected.
    • IF-cables 1-4 can be connected to the inner or outer bands. IF-cables 5-8 can only be connected to the outer bands.
    • Selection of IF outputs is restricted by the following exclusion table (RxA+RxB refer to E0/E1, E0/E2 or E1/E3):
      • VL on RxA excludes the use of VU on RxB
      • VU on RxA excludes the use of VL on RxB
      • HU on RxA excludes the use of HL on RxB
      • HL on RxA excludes the use of HU on RxB
    • WILMA, 4MHz, and VESPA can only be connected to IF cables 1-4.

  • In October 2012, we upgraded the switch box to offer more options when using E150. See here.
