144 Keysight EXG and MXG X-Series Signal Generators User’s GuideAvionics VOR/ILS (Option 302)Using ILS Glide Slope SoftkeysTo set the ILS Glide Slope mode to produce a full or partial signal1. Press Aux Fctn > Avionics > ILS Glide Slope2. Press ILS GS Mode(Default selection is OFF.)3. Select either: OFF | NORM | Suppress Up | Suppress DownThese softkeys allow selection of a complete or partial ILS Glide Slope signaland can set the ILS Glide Slope Mode to one of the following:— Selecting OFF turns off all ILS Glide Slope signals. When set to OFF, allILS Glide Slope mode parameter settings are turned off, but the selectedILS Glide Slope carrier is still present on the RF Output connector. To turnoff this ILS Glide Slope carrier, set RF Off/On to Off.— Selecting NORM turns on both Up (90 Hz) and Down (150 Hz) ILS GlideSlope signals.— Selecting Suppress Up turns off the Up (90 Hz) ILS Glide Slope signal.— Selecting Suppress Down turns off the Down (150 Hz) ILS Glide Slopesignal.To set the ILS Glide Slope carrier frequency1. Press Aux Fctn > Avionics > ILS Glide Slope2. Press Carrier Freq Index(Default value is 1 and corresponds to 334.70 MHz.)3. Select a value from 1 to 40 (see table) and press Enter.There are forty channels that are allocated to the ILS Localizer in the rangefrom 108.10 to 111.95 MHz; each ILS Localizer carrier has a corresponding ILSGlide Slope carrier frequency in the range from 329.15 to 335.00 MHz.The default ILS Glide Slope carrier frequency Index is 1 and corresponds to334.70 MHz.ILS Localizer and Corresponding ILS Glide SlopeCarrier Frequencies (MHz)ILS LocalizerIndex 1-20ILS GlideSlopeIndex 1-20ILS LocalizerIndex 21-40ILS GlideSlopeIndex 21-401=108.10 1=334.70 21=110.10 21=334.402=108.15 2=334.55 22=110.15 22=334.253=108.30 3=334.10 23=110.30 23=335.004=108.35 4=333.95 24=110.35 24=334.855=108.50 5=329.90 25=110.50 25=329.60
