Sensitivity
The sensitivity of the transponder to S-Band and X-Band signals can be set independently. The HIGH, MEDIUM
and LOW settings are related as described in the following example:
A radar that just triggers the transponder at some range (say 40km) when the HIGH option is selected would
need to be at half that range (20km) to trigger a response if the MEDIUM setting was selected. Similarly, if
LOW had been selected, then the radar would need to be at half the range again, i.e., 10km.
When the OFF option is selected, any pulses received in that band are ignored.
