Notes
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 1 kHz, that causes a 1.1 kHz
FM modulation of the local oscillator and thus of the wanted signal; V_wanted = 100 dBµV; f_unwanted = f_wanted + 5.5 MHz.
The FM modulation is measured at the oscillator output with a peeking coil using a modulation analyser with a peak
to peak detector and a post detection filter of 300 Hz up to 3 kHz.
3. Channel SO2 beat is the interfering product of f_RFpix, f_IF and f_osc of channel SO2; f_beat = 37.35 MHz. The possible
mechanisms are: f_osc − 2 × f_IF or 2 × f_RFpix − f_osc. For the measurement V_o(IFOUT) = V_RFpix = 115 dBµV.
