Peak Hold
5.1.5 Spurious Emissions at the Antenna Connector
Measurement conditions:
Peak Hold, Modulated Carrier
a. Measurement averaged over a burst and then averaged again over 50 bursts.
b. In each of the bands 925-960 MHz and 1805-1880 MHz up to five spurious measurements can fail these limits, in which
case the limit ≤ -36dBm shall apply.
