13). 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.
14). The supply ripple susceptibility is measured in the application board (Chapter 4), using a spectrum ana-
lyser connected to the IF output. An unmodulated RF signal is applied to the test board RF input. A sinewave
signal with a frequency of 500 kHz is superposed onto the supply voltage (see 5.5.8 on page 49). The ampli-
tude of this ripple is adjusted to bring the 500 kHz sidebands around the IF carrier to a level of 53.5 dBc referred
to the carrier.
15). This is the level of divider interferences close to the IF frequency. For example channel S3: fOSC = 158.15
MHz, 1/4 fOSC = 39.5375 MHz. Divider interference is measured with the application board (Chapter 4). All
ground pins are connected to a single ground plane under the IC. The LOWIN input must be left open (i.e. not
connected to any load or cable). The MIDIN and HIGHIN inputs are connected to a hybrid. The measured level
of divider interference are influenced by layout, grounding and port decoupling. The measurement results be-
tween various applications and the reference board could vary as much as 10 dB.
16). Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator. The rejection
has to be greater than 60 dB for an IF output of 100 dBV.
17). The reference frequency rejection is the level of reference frequency sidebands (e.g. 62.5 kHz) related to
the carrier. The rejection has to be greater than 60 dB for an IF output of 100 dBV.
