EXT AM [SENS. 1V/100%]
Switching on/off an external modulation signal via socket EXT1.
OFF External AM input EXT1 switched off.
ON External AM input EXT1 activated.
The sensitivity is 10 mV per percent of modulation
depth.
IEC-bus command SOUR:ILS:SOUR INT2, EXT
Note: As the automatic level monitoring of the external
modulation signal is switched off in this operating mode,
there can be an overmodulation as a function of the level
of the external signal without a corresponding caution
message being generated.
In order to avoid an overmodulation, the peak value of
the external signal is to be delimited corresponding to the
sum of the modulation depths of the remaining ILS signal
components.
