External AF input
Via the AF input (AF-EXT) at the rear side the unit can be fed with an AF signal for further analysis of
typical AF parameters (e.g. level, frequency). This is very applicable for receivers which cannot per-
form AF analysis.

DSP output
On the DSP-OUT at the rearside e.g. a XY-tracer can be connected. The scaling of the XY values
can be set for any mode (localizer/glideslope) in the setup (DDM Y / t-RANGE) or in ILS-Mode
(Y / t-SETUP).
