7). N+5 -1 MHz is defined as the input level of channel N+5, at frequency 1 MHz lower, causing FM sidebands
30 dB below the wanted carrier.
8). Limits are related to the tank circuit used in the application board
be adjusted by the choice of external components.
9). The frequency shift is defined as a change in oscillator frequency when the supply voltage varies from
V
ment.
10). The frequency drift is defined as a change in oscillator frequency when the ambient temperature varies
from T
11). The switch-on drift is defined as a change in oscillator frequency between 5 s and 15 min after switch-on.
The oscillator is free running during this measurement.
12). The supply ripple susceptibility is measured in the application board
analyser connected to the IF output. An unmodulated RF signal is applied to the test board RF input. A sine-
wave signal with a frequency of 500 kHz is superposed onto the supply voltage
amplitude of this ripple is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of 53.5 dBc
with respect to the carrier.
