Page 6 of 29 3.2 Transmitter requirements 3.2.1 Carrier Frequency Separation Procedure: The carrier frequency separation was measured with a spectrum analyzer connected to the antenna terminal, while EUT had its hopping function enabled. After the trace being stable, the reading value between the peaks of the adjacent channels using the marker-delta function was recorded as the measurement results. The spectrum analyzer is set to: Span = 15 MHz (wide enough to capture the peaks of two adjacent channels) RBW = 30 kHz (1% o…
