1. To pin 24, input a fOB / fOR signal with an amplitude of
100mVp-p.
2. Attenuate the input signal with an attenuator and detect
the achromatic level. Define the pin 24 input levels where
the killer operation turns on and off.

1. No signal is input to pin 24.
2. Measure the DC voltage of pin 29 (SECAM ID) and
define as SI.
3. Vary the external voltage applied to pin 29. Define the ID
voltage for SECAM color as SC.
4. Define the difference between the ID voltages in the
above modes as SI (SC-SI).

2. Attenuate the input signal with an attenuator and detect
the achromatic level. Define the pin 24 input levels where
the killer operation turns on and off. (Check the killer
operation by turning the SECAM ID switch on and off.)
Define the switching SECAM ID voltage as V29.
