Notes
1. This is the level of the RF signal (100% amplitude modulated with 11.89 kHz) that causes a 750 Hz frequency
2. The frequency shift is defined as the change of the oscillator frequency when the supply voltage varies from
3. The frequency drift is defined as the change of the oscillator frequency when the ambient temperature varies from
4. The switching on drift is defined as the change of the oscillator frequency between 5 seconds and 15 minutes after
5. The ripple susceptibility is measured for a 500 kHz ripple at the IF amplifier output using the measurement circuit;
6. This is the level of divider interferences close to the IF frequency. For example:
7. Crystal oscillator interference means the 4 MHz sidebands caused by the crystal oscillator.
8. The reference frequency rejection is the level of reference frequency sidebands related to the sound subcarrier.
9. Channel x beat: picture carrier frequency (69.25 MHz) and sound carrier frequency (74.75 MHz) both at 80 dB V,
10. Channel S02: picture carrier frequency is 76.25 MHz at 80 dB V, f

the level of the ripple signal is increased until a difference of 53.5 dB between the IF carrier set at 100 dB V and the
sideband components is reached.

The VHF RF input must be left open (i.e. not connected to any load or cable).
The UHF RF inputs are connected to a hybrid.
The rejection should be >60 dB for an IF output signal of 100 dB V.
