AirSpy Mini/R2

AIS-catcher [-d serial number] -gm [setting value] ...

The AirSpy Mini/R2 requires careful gain configuration as described here. As outlined in that reference there are three different gain modes: linearity, sensitivity and so-called free. These can be set via the -gmswitch when using the AirSpy.

We can activate 'linearity' mode with gain 10using the following AIS-catcher command line:

AIS-catcher -gm linearity 10

Settings can also be provided per stage:

AIS-catcher -gm lna AUTO vga 12 mixer 12

More guidance on setting the gain model and levels can be obtained in the mentioned link.
