Quick Frequency Response Test of ET 91 with Multi Tone Test Signal
MTTS METHOD: ■ The transmitter generates 35 test tones ■ The receiver measures the 35 test tones simultaneously
ADVANTAGES: ■ No synchronisation is necessary between the two instruments ■ The measuring time is shorter than that of other methods
