How to use the hybrid
to get circular polarization channels from the Shigh RX
(1) Choose the 10-GHz up-down coversion path:
vw% ifsetup sbh 3500
(2) Have to include the hybrid into the IF path, and
apply some phase angle between the two linears.
vw% set sigphdeg 90
vw% set if1setup "if1_hybrid true if1_phdsig $sigphdeg"
vw% if1 $if1setup
(3) Optimum phase-values measured at different
frequencies on 12th May 2005 are:
| 90 deg
The above commands should be entered to the VX_works system either on
the online computer or using a widget via "user preferences"
