s This value is only guaranteed in lab.
1). The RF frequency range is defined by the oscillator frequency range and the intermediate frequency (IF).
2). This is the level of the RF unwanted signal (50% amplitude modulated with 1kHz) that causes a 1.1 kHz
FM modulation of the local oscillator and thus of the wanted signal; Vwanted = 100 dBV; funwanted = fwanted +
5.5 MHz.
3). This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequen-
cy deviation on the oscillator signal producing sidebands 30 dB below the level of the oscillator signal.
