4. Ident : Allows the use to select the audio identifier of the ARTS 7000 generated ILS signal.
Possible Selections are:
a. Off – No Audio Ident
b. Code – the ARTS 7000 generates a repetitive Morse code identification signal
comprising the letters LSB. This LSB morse signal is sent every 30 seconds. The
morse can be instantly transmitted manually by pressing the
Code button.
c. Tone – the ARTS 7000 generates a constant 1 kHz audio tone .
5. To/From : Allows the selection of either:
a. To the Beacon (ARTS 7000) indication.
b. From the Beacon (ARTS 7000) indication.
6. Tone Delete : Gives the operator control of the 30Hz reference and 30Hz Variable
elements of the VOR signal. This function is used to test the response of the radio when
an invalid signal is received. Cockpit warning/fail flags should be displayed when any
element of the two 30Hz signals are deleted. The aircraft receiver should extinguish
warning/fail flags when the valid signal is returned.
Possible selections are:
a. 30Hz Ref – Switches off the 30Hz Reference element.
b. 30Hz Var – Switches off the 30Hz Variable element.
c. Both – Switches off both the 30Hz Reference and Variable elements.
7. 30Hz Mod : This setting allows control over the 30Hz variable phase modulation depth.
The Default setting is 30Hz which is the normal operating value.
8. 9960Hz Mod : This setting allows control over the 9960Hz sub carrier modulation depth.
The Default setting is 30Hz which is the normal operating value.
9. AUTO – when the Auto function is enabled the ARTS 7000 sets up a VOR signal IAW the
selected frequencies, Power Modulation and Ident. The VOR signal from the ARTS 7000
then automatically steps the bearing in the selected step range from 0 Degrees to 360
Degrees. Once this full-scale sweep is complete the VOR signal will be reversed from 360
Degrees to 0 Degrees. The ARTS 7000 will continue to sweep the bearing through full
range until the Auto button is pressed again. This sweeping the instrumentation across full
scale. This process will continue to run until Auto is pressed again. This simulates the
aircraft being tuned to a VOR beacon and flying in a circular motion back and forth around
the beacon. This process is continuous until the Auto is switched off. It is intended that
this function can be used to fully exercise the VOR system continuously and can also be
used for trouble shooting poor connections or damaged cables.
