6124.9007.82.01 3.12
8 Harmonic Emissions
8.1 Set transceiver to modulation F3E without
modulation. No modulating signal at audio in-
put X26.10/.40 of transceiver.
Set transceiver to the following TX
frequencies. By using the spectrum analyzer,
measure harmonic emissions related to the
TX frequencies:
1.5 MHz
2.2 MHz
3.2 MHz
4.6 MHz
6.7 MHz
9.7 MHz
14.2 MHz
20.6 MHz
27.0 MHz
29.99 MHz
The greater harmonic product (first or
second) must be below the test value.
TX power set to 10 mW:
≤ -40 dBc
TX power set to 100 W:
≤ -45 dBc
9 Max. Current Consumption in Transmit
State Mode F3E
