Title: Satellite repeater monitoring device
Inventor: MACHINO YOSHIATSU
IPC: H04B1/707
Filed: 1988-07-21
Abstract: PURPOSE:To measure the saturation characteristics of a satellite repeater even in a frequency band in which the ground power flux density is severe by connecting an AM modulator after an FM modulator, and taking out a required AM modulated signal component alone by means of a band-pass filter on the receiving side. CONSTITUTION:An FM modulated signal generator 13 outputs symmetrical triangular waves and the IF carrier inside an FM-modulator 12 is FM-modulated by means of FM modulated signals and diffused so that the amplitude becomes constant on a frequency axis. Moreover, the waves to be FM-modulated are AM-modulated by the next AM modulator 1. The FM-modulated waves are converted into RF signals and transmitted to a satellite. Signals passed through a satellite repeater are passed through an AM demodulator 10 and band-pass filter 14 having a center frequency equal to the frequency of the AM-modulated signals and FM-modulated signals and carrier components are removed after the signals are received and converted into IF signals by means of a down converter 9. Therefore, detection of the saturated point of the satellite repeater by means of the waves to be AM-modulated becomes possible even in a frequency band in which the restriction of the ground power flux density is severe.
