Next: Polarimeter XPOL
Up: The single pixel heterodyne
Previous: Extended tuning range: 72
Tuning of the single pixel/dual polarization receivers is now
considerably faster and more reproducible than before.
Particular frequencies, like those in the range 72 - 80 GHz or
those near a limit of the tuning range,
may still be problematic. In these cases, we recommend
to check with a Granada receiver
engineer at least two weeks before the observations.
HERA observers, however, are requested to send their frequencies as
soon as their project gets scheduled.
