Loc Audio Control Mode (Loca) Field Definition - Aeroflex NAV 2000R Operation Manual

Aeroflex Operation Manual
IDENT MODE
The ident mode field selects the identification tone modulation method. This is a toggle field containing
three valid options: OFF, CODE, and TONE. A selection of OFF, the default setting, commands the unit
to force the percent of modulation to 0%. Selecting CODE, causes the unit to Morse code modulate the
specified identification string. And a selection of TONE, commands the NAV 2000R to modulate a 1020
Hz tone.
PAGE 3:
IDENT CODE
Allows modification to the identification string transmitted. The field uses the alphanumeric field entry.
The characters allowed in the string are 0-9, A-Z, and the space. Characters lengths of 1 to 6 are
allowed. The default for this field is the string "JCAIR".
WORD RATE
Allows programming of time between each identification word. The valid range for the field is from 1 to
65 seconds programmable in 0.1 second steps. The default setting is 30 seconds.
DOT TIME
Allows programming of Morse code dot time in milliseconds. The valid range is from 50 ms to 250 ms in
1 ms steps. The default value is 150 ms.
DASH TIME
Allows programming of Morse code dash time in milliseconds. The valid range is from 150 ms to 750 ms
in 1 ms steps. The default setting is 450 ms.
SPACING DOT/DASH
Allows programming of delay time between Morse code dots and dashes. The valid range is from 150
ms to 750 ms in 1 ms steps. The default setting is 450 ms.
SPACING CHARACTER
Allows programming of delay time between Morse code characters. The valid range is from 50 ms to 250
ms in 1 ms steps. The default setting is 150 ms.

3.5.8 LOC AUDIO CONTROL MODE (LOCa) FIELD DEFINITION

The Localizer audio control mode, LOCa, is entered by pressing and releasing the SEL key while the
AUDIO control mode field, LOC page 1, is selected. This mode allows the user to specify the NAV
2000R audio output signal level using volts RMS. No RF level control is allowed while within this mode of
control.
COMPOSITE AUDIO CONTROL:
AUDIO LEVEL
This field allows the audio signal level to be changed. The value entered represents Vrms of the
Localizer composite signal with both 90 and 150 Hz signals selected on, and a DDM setting of 0 DDM.
