4.2

Power spectral density

The measurement shall be performed at the lowest, the middle, and the highest channel on

which the equipment can operate.

The transmitter shall be connected to a spectrum analyzer with the following settings:

Start Freq: 2400 MHz; Stop Freq: 2483.5 MHz; Res BW: 10 kHz; Video BW: 30 kHz

Sweep Points: > 8350; Detector: RMS; Trace Mode: Max Hold; Sweep time: Auto

The measures show a value in line with the limit: 10 dBm/MHz.
