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).
