VOR/ILS Analyzer EVS200

 

 

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>

e.g.

09.6% <CR/LF>

 

am9 <CR>

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>

output form: (RF level <CR >, Bearing <CR >,

 

fa2 <CR>

AM30 <CR >, AM 9960 <CR >),

 

With the command FA2 the echo

FM-deviation<CR >,

 

mode is automatically switched

FM-Index <CR >),

 

OFF.

RF level: three-digit with indication (dBm)

 

 

 

 

example: -400 <CR > (-40.0dBm)

 

 

 

122 <CR > (12.2dBm)

 

 

Modulation depth:

three-digit (%)

 

 

example:

304 <CR > (30.4 %)

 

 

 

004 <CR > (0.4 %)

 

 

FM-deviation:

four-digit (Hz)

 

 

example: 4800<CR > (480,0Hz)

 

 

 

0004 <CR > (0.4 Hz)

 

 

FM-Index:

three-digit

 

 

example:

160<CR > (16,0)
