TRANSCRIPT
Measurement Equipment• ILS field receiver, Type EVS-200 of Rohde&Schwarz
Raw data acquisition at 33 Hz for DDM and RF-Level
• Antenna Rohde&Schwarz HF-108Directivity: gain is 1.2 at 112 MHz, front to rear and right/left ratios 6 dB
• In special cases (Position 2 and 8) the opposite LLZ antenna was used as receiving antenna
• Notebook PC for recording with ILMA (DFS ILS Measurement Application) Post processing and filtering evaluation by help of Excel for ICAO Filtering at different speeds T[sec]=92,6/V[km/h]typical speed: 60 km/h, in special cases (P5): 10 km/h
