"Var"
Amplitude modulation of the output signal with the VAR signal compo-
nent (30Hz signal content) of the VOR signal. The modulation depth
corresponds to the value set under VAR Depth.
"Subcarrier"
Amplitude modulation of the output signal with the unmodulated FM
carrier (9960Hz) of the VOR signal. The modulation depth corre-
sponds to the value set under Subcarrier Depth .
"Subcarrier +
FM"
Amplitude modulation of the output signal with the frequency-modula-
ted FM carrier (9960Hz) of the VOR signal. The frequency deviation
corresponds to the value set under REF Deviation, the modulation
depth corresponds to the value set under "Subcarrier Depth".
Remote command:
[:SOURce<hw>]:VOR:MODE on page 580
VAR/REF Frequency
Sets the frequency of the VAR signal and the REF signal. As the two signals must
have the same frequency, the setting is valid for both signals.
Remote command:
[:SOURce<hw>]:VOR:VAR:FREQuency on page 582
VAR Depth
Sets the AM modulation depth of the 30Hz VAR signal.
Note: The sum of "Subcarrier depth", "VAR depth" and "COM/ID > Depth" must be
smaller than 100 %.
Remote command:
[:SOURce<hw>]:VOR:VAR[:DEPTh] on page 582
Subcarrier Frequency
Sets the frequency of the FM carrier.
Remote command:
[:SOURce<hw>]:VOR:SUBCarrier[:FREQuency] on page 581
Subcarrier Depth
Sets the AM modulation depth of the FM carrier.
Note: The sum of "Subcarrier depth", "VAR depth" and "COM/ID > Depth" must be
smaller than 100 %.
Remote command:
[:SOURce<hw>]:VOR:SUBCarrier:DEPTh on page 581
REF Deviation
Sets the frequency deviation of the reference signal on the FM carrier.
Remote command:
[:SOURce<hw>]:VOR:REFerence[:DEViation] on page 581
