The primary focus receiver at 18-23 cm again has got new filters
because
of strong interferences and baseline problems. For that reason the old
frequency ranges changed. All frequencies can be used in the upper
or
lower sideband.
The symbols in OBSE
are:
(They automatically set the right
configuration. One should
only use these definitions !)
- FRQRX
<frequency>
[<fixed> [ <sideband> <xx>]]]
with the following definitions:
- <frequency>: is the
observing frequency in GHz
- <fixed>:
F if the frequency shall be fixed, otherwise
it is
corrected
- <sideband>: U for
upper and L for
lower sideband
- <xx>:
if parameter present means: Take broadband (1350-1480) in
overlapping
region
The old symbols in OBSE
for the
different possible frequency-ranges are also valid:
The changed frequency-ranges are indicated in red.
