TEST DATA SHEET
F. GLIDESLOPE RECEIVER/CONVERTER
Input a standard GS deviation signal into the unit. Monitor flag for 190 mV or greater.
*1. Sensitivity:
329.15 MHz (108.95)________________ -87 dBm max
332.00 MHz (109.30)________________ -87 dBm max
335.30 MHz (110.30)________________ -87 dBm max
2. Selectivity:
Find RF level that produces 1/2 flag. Increase the RF level by 6 or 60 dB. Vary
frequency until 1/2 flag occurs and record frequency.
Upper 6 dB Frequency________________ (
≥
332.020 MHz)
Lower 6 dB Frequency________________ (
≤
331.980 MHz)
Upper 60 dB Frequency________________ (
≤
332.145 MHz)
Lower 60 dB Frequency________________ (
≥
331.855 MHz)
3. Centering:
Input a -56 dBm, 0.000 ddm signal into the unit. Monitor the D-Bar.
