Rohde & Schwarz FMAV

This unit measures with utmost precision all modulation parameters relevant in VOR and ILS air navigation systems, for example ILS DDM to an uncertainly of +/- 0.0002 DDM and VOR phase to an uncertainly of < 0,1°.

With its extremely low measurement error achieved by means of digital signal processing, FMAV meets the stringent requirements placed on measuring instruments for ILS systems of category III.

Its high accuracy makes FMAV also ideal for use as a calibrator for VOR and ILS signal generators like Radio communication Service Monitor CMS 57.

With CMS 57 as a signal generator used in conjunction with FMAV as a demodulator, Rohde & Schwarz offers a complete, state-of-the-art test system for aeronautical radio.
