Res. FM Filt. (ILS only)
Defines the filter type used to determine residual FM (see Chapter 5.1.3.4, "ILS Local-
izer Distortion View" , on page 49).
"ICAO" Filter according to ICAO specification
"Narrow" Narrow filter; the DDM filters used to determine the 90 Hz/ 150 Hz
modulation values are used to avoid interference between the signals
Remote command:
FILTER_LLZ_RESIDFM

5.1.4.4 Setting the Measurement Time (MTime)
Access : [MTime]
Access VNC : [d]
The measurement time determines the interval at which new measurement results are
displayed. Internally, values are captured every 100
ms, that is: 10 per second. (With
the High Measurement Rate option R&S EVSG-K22 installed, the internal capture rate
is 10 ms, that is: 100 per second.) If the defined measurement time is longer, the val-
ues captured internally in that interval are averaged and only the average value is dis-
played.
Note that the measurement time determines the minimum interval for values to be
stored during recording (see
"Time" on page 170).
Enter the time in milliseconds.
