General Information1-10 560-0982-00 Rev D Apollo CNX80 Installation ManualFrequency range...........................................329.150 to 335.00 MHzFrequency tolerance......................................0.0008%Cross modulation products ...........................At least 60 dB downReceiver sensitivity.......................................-95 dBm typicalCentering error .............................................RTCA DO-195 two sigma limit: 6.7% of full scaleSL30 performance: less than 2.0% typical (3.0 mV)1.3.8.4 Computation RatesThe tuned active frequency is computed 10 times per second. If the VOR monitor function is activated,20% of each second is allocated to the monitored frequency, slightly decreasing the active to frequencycomputation rate. It is important to note that the monitored frequency is only updated once per second.1.3.9 AVIONICS INTERFACES1.3.9.1 Main CDI (GPS or VHF Nav)1.3.9.1.1 Deviations / Flags / AnnunciatorsCDI L/R deviation........................................±150 mv full scale (200 Ω load max)TO/OFF/FROM flag....................................±250 mv, TO/FROM (200 Ω load max)Nav valid flag ..............................................+300 mv for valid indication (200 Ω load max)Nav superflag...............................................Vin - 2 volts (minimum) for valid, source capabilityof 400 mAVDI up/down ...............................................±150 mv full scale (200 Ω load max)VDI valid flag ..............................................+300 mv for valid indication (200 Ω load max)VDI superflag ..............................................Vin - 2 volts (minimum) for valid, source capabilityof 400 mAGPS/Nav Annunciators ................................Open collector outputs capable of sinking up to 400mA for turning ON annunciator lamps1.3.9.1.2 OBS ResolverTSO compliance...........................................TSO-C40c (DO-196)Applicable documents...................................RTCA DO-196Operational class..........................................N/AAccuracy category........................................B {-46oC to + 55oC}Output signal ...............................................300 Hz ± 2 Hz (rounded square wave)Output voltage (automaticallyadjusted during calibration) ..........................5 Vpp to 10 VppInput voltage max (calibrated) ......................5 Vpp (when OBS is set to maximum)Resolver voltage gain (loss) ..........................1:1 maximum, 2:1 minimumOutput loading at max voltage......................100 ohms impedanceAccuracy/Resolution ....................................0.25o rounded to 1o steps
