Chapter 3: Operation
Command AM9
command function
AM9 <AM-modulation depth (voice)> query AM-modulation depth (voice)
The command AM9 reads the actual AM-modulation depth (voice 300 Hz to 3 kHz) in the ILS / VOR
mode.
Prediction for reading out the data of the corresponding mode (VOR/ILS) is the
switching over to display2.
Example:
command from the controller
response of the VOR/ILS Analyzer EVS200
query:
AM9 <CR>
am9 <CR>
e.g. 09.6% <CR/LF>
e.g. 09.6% <CR/LF>
Command FA2
command function
FA2 <Fast measuring on> Activating the Fast measurement mode
The command FA2 switches on the fast measurement mode. The command FA2 performs the con-
tinuous measurement and output of the RF level, Bearing, AM30, AM9960, FM-deviation, FM-
Index with transmission speed of 15 measurement value sets (RF level, Bearing, AM30, AM9960,
FM-deviation, FM-Index) per second. This conforms to a time interval of 66 ms. The stated RS-232-
transmission times are related to 19.200 Baud.
The measurement values can be read in and output as a text file corresponding to the terminal pro-
gram.
The baud rate must be set to 19200 baud in the Setup of the VOR/ILS Analyzer EVS200.
It must be attended the acceptance of the data transfering rate by the terminal pro-
gram.

 The measurement can be stopped through the command FA0 (refer to Command FA0).
Example:
command from the controller
response of the VOR/ILS Analyzer EVS200
input: FA2 <CR>
fa2 <CR>
With the command FA2 the ech
