Frequency Display Offset
It is possible to connect the
Artemis
to a down-converter to receive
frequencies which are normally beyond the
Artemis
’ frequency range. In this
scenario, it is convenient to see the actual received frequency rather than
having to manually transpose the displayed frequency to the down-converter’s
input signal.
For this purpose, there is an option to add a user-defined offset to the
displayed frequency. This option is called
Display offset
and is located under
the
Options
top menu bar:
As usual, you can enter the display offset in Hz, kHz or MHz by terminating the
entered value with either
h
,
k
or
m
, respectively, if you prefer to change the
displayed frequency unit.
An option to invert the spectrum is provided for situations where the spectrum
is inverted by the down-converter.
Receiver Selection
Clicking on one of the three
Receiver tabs
located above the main frequency
display selects that particular
virtual receiver
. The other receivers continue
operating provided their frequency fit within the current DDC1 spectrum
bandwidth.
The tuned frequency of each receiver is displayed inside their associated tabs.
